Alright so I've been seeing allot more people running holsets these days. And with information spread out all over the interweb I would like to make a collective source for all s-chassis people running them. Like what manifold you're using, injectors, boost, where you got your rebuild kit, power etc. But most importantly PICS.... I have none at the time as I am waiting on a rebuild kit for my hx30w. So I'm counting on you guys lets see your setups. I ordered the rebuild kit form baeturbosystems $73 shipped.

such a great IDEA this thread.

Most of them are either t3/t4 or t4 twin scroll...
manifolds aren't hard to make with a little patience and a mig. and of course cast irons are easy to come by.

I love holset turbos, HX35 is a good sr20 turbo. I'm a little rusty with reading compressor maps but if anyone wants to know which holset turbo will go with their motor, and respective power gains, just post here and ask me.

I'll get the maps and show you how much boost / power you'll get for each one. took me weeks to learn, but im eager to help.

I have a 8 blade holsett hx35... I have a vvl w/p12 cams in my s13... Havent tuned or anything yet, but Im looking to use 15psi daily and ~25psi at the track...

what kind of power do you see at both levels?

Got a 4.3 Gtst Diff also, what kind of 1/4 with the right sized slicks?

1 psi is approximately 7 hp

15x7 = 105hp ...what does that mean?

Holsets are good for cheap power. Bear in mind they were made to work with much greater exhuast volume, so it will effect efficiency. That and they are ship anchor heavy.

he means gain, so if you're making 200 hp @ 7 psi, you would be making 249 ish @ 14psi... not sure if that's accurate, but i believe that's what he means...

I have a Wh1c, which is the same as an early HX35, on my S30 I'm currently running 15psi. I basically unbolted it from the cummins and bolted it to my L28. I did however have to port the heck out of the exhaust housing, wastegate hole, and I eventually retrofitted a bigger wastegate flapper to take care of boost creep.

Stock 280zxt exhaust mani
Stock motor
42# injectors
15 psi of boost
Around 300hp to the wheels

I was going to ask if anyone was using the internal wastegate in my first post. Can you remember how big you bored it out? And what actuator did you use?

hx30 is too small for a 2.0 liter engine. SR20 flows up to 630 CFM at 7000 rpms. This turbo cant keep up with your motor, and it would be worse on a KA.

I've done this a million times but its been a while. (http://forums.nicoclub.com/holset-hx40-vs-rb25-neo-t439733.html?hilit=compressor#p4945506)

>>> HOW TO READ A COMPRESSOR MAP. <<<
You can use this method with ANY MOTOR, and ANY TURBO

-------------------------------------------

X - CFM ( cubic feet per minute ) this is the volume of air the engine is moving out the manifold and into the turbo's exhaust housing every minute.*

you'll need Enthalpy tune CFM calculator. (excel doc) (http://api.viglink.com/api/click?format=go&key=dc030a8cad8d809f44b40cadb5b817de&loc=http%3A%2F%2Fforums.nicoclub.com%2Fholset-hx40-vs-rb25-neo-t439733.html%3Fhilit%3Dcompressor%23p4945506&v=1&libid=1326486056758&out=http%3A%2F%2Fwww.rs-enthalpy.com%2Ftuning%2Fcompressormath.xls&ref=http%3A%2F%2Fforums.nicoclub.com%2Fsearch.php% 3Fkeywords%3Dcompressor%26terms%3Dall%26author%3Dk alypso%26sc%3D1%26sf%3Dall%26sr%3Dposts%26sk%3Dt%2 6sd%3Dd%26st%3D0%26ch%3D300%26t%3D0%26submit%3DSea rch&title=Holset%20HX40%20vs%20rb25%20neo%20%3A%20RB20 DET%20%2F%20RB25DET%20%2F%20RB26DETT%20Forum&txt=%20HERE!%20&jsonp=vglnk_jsonp_13264863880233)

to START, Enter in the CC of your motor, for an SR20 (2.0 liter) its 2000
for a KA ( 2.4 liter ) is 2400... Nissan has the exact cc if you search on google for any motor you want.

Y - Pressure ratio: This is how much boost the turbo is pumping
( 1 bar is 14psi of atmosphere, everything above that is BOOST. )

- 1.0 = 14.503 psi ( remember again that atmosphere naturally makes 14psi on its own... ) thats why the compressor map doesnt go down to 1 cause the turbo isnt spooling yet.

- 1.5 = 21 psi ( 21lbs - 14lbs [of atmostphere] = 7lbs of boost )

- 2 = 28 psi ( 28lbs - 14lbs [of atmostphere] = 14lbs of boost )

ect...

-------------------------------------------

look at the line going through the center of the compressor map, that's indicative of the pressure under ideal boost conditions. the shape of the map defines the effective area of the turbos efficiency.

1psi OVER NA = 7hp gain.

A couple of years ago I started researching holset turbos. I was going to run a holset hx40 pro and have seen pretty good results with these turbos. There are huge write ups consisting of graphs and all kinds of technical talks on the dsm forums. They have dyno graphs and reported horsepower numbers. These turbos are very popular with the mitsubishi guys. For instance there is a guy on that forum that made 685 awhp on an hx40 and you can get exhaust housings for holsets through bullseye power's website.

hx35 is a big turbo... and it will spool hard on an RB25.

@ 3K RPM = 11 Psi
@ 7k RPM = 39.2 Psi !!!

that's approx 450 - 500hp

( assuming that this map's turbine housing is the one your going to use )

I initially tried to port the wastegate hole still using the stock flapper, still creeped. Took the turbo back off and removed the divider all the way down to the wastegate hole, solved the majority of the problem. To put it to bed I bought a 34mm flapper from forged performance and ported the hole to the new flapper, No more boost creep. I'm using a custom mounted, shortened, rethreaded 7psi wastegate from a mid 80's 300zx.

I'm getting:
@3000 rpm 156 CFM @ 7psi

Regardless, like you said, the compressor housing is not a good match to a 2.0L.

The Hy35 has a 9cm exhaust housing, which is like a .48ar or so. If I ever decide to upgrade, I'll go to the He351cw. Its a 9cm exhaust housing, but has the same compressor side as an Hx40. It moves along nicely as is though, so a change might be a ways off. cumminsforum.com is a good place to buy and turbobyholset.com is good for info and compressor maps.

My friend got an HX30 with the bigger inlet and anti-surge comp. housing
Compressor: IN:49MM EX:73MM AR similar to garret 0.5AR size
Turbine: IN: 64MM EX:52MM AR: 9cm
That actually could be quite a good turbo for 1.8 or 2.0l engines.

Any got the balls to plot the compressor in my last post ? HX35 and HE351 for 1j ?))

Well, to be quick and dirty, it takes 450cfm to make 300hp. The HX30 according to the map posted flows a maximum of 370cfm.

Quite frankly, you would be better off running a gt28. It will actually flow 482cfm @6500rpm @10psi. Of course these calculation are rough at best but they do give you a good idea to go from.

lowrider260

01-15-2012, 12:56 AM

Looking forward to this thread. We gonna rock that shit :)
Lets say stock 1jz non-vvti with 440cc injectors and HX35 7blade with 56mm inducer 82mm exducer. 12cm turbine housing. Wanna run 18psi and 20psi. What would it be ?
What about he351 with 60mm inducer and 86mm exducer and 14cm ar exhaust ? Turbine wheel 60mm/70mm ? Same boost ?
Here is a map of an HX35 that could be loosely applied to both the 1jz, and the Rb25.
This is reaching full boost at 3250rpm. If you anticipate it to spool later, just move the the intersection point of the diagonal and horizontal line to the right.

01-15-2012, 01:51 AM

Dude, I think ur calculations are a bit off.
All turbos are basically the same. Its just compressor/turbine wheel size and ar on the turbine which really tell the story.
Lets say we got 71mm compressor exducer be it on t3/t4 or mitsu or holset or even gt2871.
Basically they will be all capable of similar flow.
So no way a smaller GT28 will flow more air. GT28 exducer is what 60mm?
Also the turbine will flow more on HX30.
I don't believe that lower trim on HX30 compressor will reduce the flow that much.
Maybe a few lbs at most.

As for the HE351, can you do the 62mm/86mm compressor plot ? What do you think the flow be on 20psi ?

lowrider260

01-15-2012, 09:58 AM

Are they now? So the only thing that affects flow on a compressor wheel is the exducer size? Not the ratio between the induced/exducer, the compressor housing design, or the blade design of the compressor wheel?

Turbines:
Well sir, we are plotting compressor maps. The two significances that the turbine housing plays is where the "boost knee" is drawn on the graph, along with the fact of restricting maximum flow via back pressure if they are too small.

For comparison, compressor trims:
HX30 has a 44mm inducer and a 73mm exducer. The trim of the turbo would then be ((44*44)/(73*73))*100 which equals a 36 trim compressor wheel.

Gt28 has a 46.5mm inducer and a 60mm exducer. The trim would then be ((46.5*46.5)/(0*60))*100 which is a 60 trim compressor wheel.

I can post a plot of the same engine on both the gt28 and hx30 to illustrate my point.
I'll try and find one, the last time I looked I couldn't find a HE351 map.

robots

01-15-2012, 12:32 PM

This is your thread, and I have no intentions in changing that.
What I believe is compressor trim can't effect flow that much. And even garrett states, that its not a rule of thumb.
Smaller trim should mean its higher pressure ratio capable, right ?
What I get to is. Bigger wheel turbo with a similar hot side shouldn't get u less horsepower. Its not right haha )))
I just want to belive that way probably haha. Will wait for your posts.

lowrider260

01-15-2012, 01:14 PM

Yea, its a tad bit confusing. Anyhow, here are the hx30 and gt28 maps for visual reference. Both use the exact same flow numbers for an Rb25, with the maximum boost being achieved at 3250rpm.

If you search on driftworks, there's someone running a hx30 on a sr20, and his friend running a hx35. The hx35 user complained about lagginess for drifting, but loved the power delivery of the hx30 on the other car. I like results a lot more than compressor maps. I just got a hy35 that I'm rebuilding for my ka-t. I can't wait.

robots

01-16-2012, 12:48 AM

holset website states, hx30 flows 0,35kg/s at 3:1pr, about 30psi of boost. converting kg/s to lb/min will give us calculated compressor flow of 46.29lb/min. also check out trust turbo table at trust jp website. they would have approximate hp reading for every turbo.
there will be interesting turbos there with different compressor trims and turbine sizes. You should check it out. Maybe the compressor map u have for hx30 is a bit off? I believe there are several hx30s out there, and they would have different maps.

240sxluver4life

01-16-2012, 02:09 AM

Just so everyone knows, trim equals (inducer)2*(exducer)2*100. I have an hy35 on my kade. Havent started it yet but if i remember correctly i calculated the trim at 54 lb/ min.

smelly240

01-16-2012, 07:11 AM

I think the size of a HX35's compressor cover is deceiving. Its not a very big turbo as far as power output goes. They flow less than a 3076 or a 5557.

I ran them for a long time when i was younger... even ran a he351ve a few years ago (with the vgt working completely).

An 8 blade is ok if you are looking for 400ish - but a hx30 is probably too small for your average sr with cams/intake manifold.

Trim isnt measured in lb/min btw - its simply a number discribing the relationship of the size of the inducer and exducer. Lb/min cannot be "calculated" without extensive testing - it needs to actually be measured.

Ok, back to pc.
Here it is: http://www.trust-power.com/spec_swf/02turbo/Syogen.swf
http://i36.photobucket.com/albums/e22/andrei666/trust.png

Since Trusts are ex-mitsu diesel heritage. So its good info.
There are various trims for compressors. There is similar one to HX30 one.
TD06 17C or smth. Trust states it can push 300-380 hp.

Can we anticipate one's turbos hp rating ? Yeah.
Will it be 100% correct - no.

I usually just get a list of turbos compressor sizes and try to find a close match.
And see read about that turbo and real life results if applicable.

Hope it makes some sense haha.

Bring on some more results.

Maybe we should make a list of HX30 variants and HX35, HX40 with their compressor maps here ? Make the thread more educational ? Maybe even post some youtube vids with spool and stuff ? What you guys think ?

There are 2-3 HX35 I know about. Exducer 76 and 82. Inducer also runs differently from 52mm to 54 and 60mm I believe.

It will all net you with different results.

I think I'm definitely going with the he351cw.

Thanks! unfortunately I did it in stages, but the final porting did the trick It holds 10psi steady. As most know the hx35 and Wh1c have a divided t3 exhaust housing. It also only has the wastegate pulling from one side of the divider. Sooo, I cut the divider out all the way down to the wastegate hole. Then ported the hole and used the stock flapper, It still creeped a little. The be all end all was a forged performance 34mm flapper and porting to match. Like I said it holds 10psi now. I'm currently running 15psi, but I would like to turn it up to 20psi with some meth injection. I'll also include a few pics of the divider removed and the fp flapper install.

Unshrouding the flapper a bit, and you can vaguely see the difference in the wastegate hole size:

Don't stop, keep it going !
Nice work on the wastegate hole! What actuator did you end up using ?
How is the boost build up with the actuator ? Noticeably worse than with external wastegate ?

slydin240sx

Could you not just weld the internal waste gate shut? and run a external waste gate?
I don't know much about turbo's but one day would like to run a holset hx35 on my KA. So any information I can get would be great.

^ You can run an external but there $200++work. And yes lowrider what actuator are you using? I looked at the prices of those 34mm flappers, and lets just say I'm a cheap skate.
I wonder if I could cut and modify and exhaust valve to work, and if it could take the heat? I don't see why it wouldn't.

The actuator is a factory piece from a mid 80's 300zx turbo, that I had from my from my first turbo. I cut the actuator rod down, rethreaded it, modified it to mount on the holest's exhaust housing, and adapted the original wastegate arm.
You can kind of see it in this picture.
http://i558.photobucket.com/albums/ss22/lowrider-260z/untitled.jpg

The exhaust valve is a good idea, it's designed to withstand the heat in the combustion chamber. The only problem is that the exhaust valve is made to seal on the top side and most exhaust valves aren't flat on the bottom, where you need it in a wastegate flapper application.

Way less work to just have a wastegate flange welded to the manifold. You can find used Tials and other name brand wastegates for $100. Oh and SLydin240sx, everyone welds the internal gate shut when used on KA's. Every t3 manifold available has an external wastegate flange on it.

robots

01-19-2012, 01:59 AM

I dont think its turbo problem. Oil breaking up is either oil temp to high or just shitty oil.or bad luck. I ran oil cooled turbos even with no oil cooler. And the temps were all good. Bad tuning can also result in high oil temps. Check ur shit man. Its suppose to be all good.

Mainly HX35 and found some interesting shit.
Wanted to check the AR on the housings.

Pretty common 12cm on the HX35

And ohh shit. 10cm on the HX35 !!! Although it does look different to other HX35s, smaller compressor and no anti-surge inlet.

I'm running an hx30 on my KA, downpipe should be done tomorrow so I'll let everyone know how it feels. Both compressor and turbine wheel are physically larger than the ones on my old t28, I'm aiming for 300whp at around 15psi. If it doesn't work out I'll probably end up buying a friend's hx35.

Here's a link to the SR builds, one guy did an hx30 and one did an hx35. The guy running the 30 on his SR made 325whp/375tq at 19 psi, that's promising for me haha.

Here's a picture I took earlier, downpipe got welded up today and manifold just about done, should be up and running tomorrow. I'll try to find some pictures of just the turbo.

Edit: Found some more pictures. Seems like the hx30's only came with 6cm, so I have a 6cm housing. The hx35 pictured has a 9cm housing, and the hx40 has a 17cm housing. Looks like I might be upgrading to the hx35 soon, but that dyno graph with the SR makes me want to keep the 30 for how much torque it makes. I'll see how it feels tomorrow though, previous setup was 293/310 with a t28 so I can compare it to that.

I feel like I'm rambling about the hx30, but I just looked up some compressor maps. The hx30 flows more than a gt28rs, and at a much lower pressure ratio, so I don't know where people are getting the notion that the hx30 doesn't flow enough for 300whp. Here are the maps for comparison.

http://www.dsmtuners.com/forums/attachment.php?attachmentid=92009&stc=1&thumb=1&d=1283352997

http://www.atpturbo.com/root/maps/images/gt28rscompress.gif

At 15 psi, the KA is right in the middle of the hx30's compressor map. At the same boost level, the gt28rs is almost out of the efficiency range. My friend who is welding up everything ran out of Argon so I won't be able to drive it until probably Tuesday, but I still think the hx30 will be plenty capable of 300 whp.

-He351cw (Spools faster than the hx35, but makes the same power) flows approx 60.85 lbs/min
-Hx40, flows approx 70.10 lbs/min
-Hx45 (can't find the flow at this time)
-Hx50/52 or 55. flows approx 99.20 lbs/min

The 35 will be good for what you're looking for. Spool a bit slow but mine was good for that power.

For 350hp only I think HX30 will be better suited. Beware though, there are 2 types of HX30. One with very small Inducer. And another one bigger. U should get the later one.

IN:49MM EX:73MM
Turbine: IN:64MM EX:52MM
Good rear specs also.
More like TD06 20G, a tad tad larger. So it would be good spec for RB20.

Cheers.

Well cant see it at the moment. its gettin shipped but Its a hx30w. Is that the one that im looking for? How much sooner should I see full boost on this compared to the hx35?

76+ compressor vs 73mm
Is ur HX30 with anti-surge compressor ? If it is, u are getting the right one.
If not - the smaller one.

I know this isn't exactly a Nissan engine, but it's in my S13.

Modified HX35 for external gate, Stock twin-scroll 12cm2 housing. I would encourage anyone looking to do an HX35 to stick with the stock housing, weld the wastegate shut, and use a twin-scroll manifold. The setup on my buddies stockblock evo makes 28psi in 4th at 3500rpm.

that 4g is going to be awesome. at our shop we have built multiple dsm's with them. always a great pair. i have a 2g with a built motor running a 16g with a 20g wheel bored out in the compressor housing. 20psi by 3800 rpm. going to be turning it up to 28 here soon! another cheaper setup with incredible results.

Yeah I'm thinking so as well. Is yours a 6 or 7 bolt?

Mine will be a 2.3 stroker and I'm hoping the hx35 will pull some ridiculous spool numbers.

RB25 with HX35. The ebay manifold had to have the flange cut off and angled away from the valve cover. Full spool (15psi) is around 4k depending on load and gear.

Hey, did you tune your car? how much hp is pushing? i have the hx35 with rb25 too! i get full boost 15psi on 5k rpm.. i think is due to the crappy CX racing turbo manifold that i have..

Have you ever seen what they do on the stock 12cm2 twin-scroll housing?

Stock 2.0 6bolt with 272 cams at 30psi. I've never seen an SR or KA that has used the stock housing on an HX35, otherwise I would post one of them.

I think this would be a killer setup on a stock SR or build KA.

If its leaking it will cause you to lose boost pressure, making it not boost as rapidly.

RB25, HX52, ebay twin scroll, twin Tial 38s, 4" downpipe to 3.25" cat back.

Impressions so far: surprisingly nice spool for such a monster. In 1st gear, boost hits hard at 5k. In 3rd, it starts spooling at around 3.5k with 10psi (gate pressure) at a little under 5k. I still haven't driven this thing much or adjusted the tune, but it should get better with an electronic boost controller and some timing. On 10psi at 7200rpm, the z32 maf was reading 4.650v.

Size comparison to my hx35 compressor cover.

For those of you that don't know, this turbo compares roughly with the 2860r. It has a 44mm inducer, compared to the 47mm inducer on the 2860. But the exducer is significantly larger at 73mm vs 60mm for the garrett. This should make it better at higher pressure ratios, and the 65mm turbine flows a lot more than the little 54mm on the Garrett. Even with the bigger wheels, it should spool faster in the twin-scroll housing. There is an SR20 in the UK making over 350 to the wheels on this turbo.

Im looking for a hx30 on my bone stock ka-t. But haven't found any feedback on it like quick spool. I've heard the hx30 is to small? My setup now makes 270hpit at 7psi so not looking for much more power.

An hx30 is about the size of a 2860 depending on which compressor wheel you get. Basically instant spool on a KA. The bigger compressor wheel is good for over 350whp, no one has really pushed it past 20psi.

not really, i don't mind the lag that much,

closest thing would be when i had a gt3071 on my sr, and that felt a lot more laggier than the hx35 on my ka.

Do you have a 12cm2 housing? What gear are you thinking? It looks like the Boost Junkyz manifold is 1.25 runner, so 3800rpm in 3rd and 3500rpm in fourth. Full spool.

That turbo is good for over 500whp depending on boost, what are you planning on running it at?

Get that dyno'd! So people can see what the HX35 can do on an SR! Everyone I've seen runs open scroll and complains about the lag.

4G, Custom bell housing, and a holset wins all day.

Oh i will get it dyno'd for sure. im aiming for higher hp/fast spool. Im just in the midst of buying a forged built sr20 off here. deals keep falling threw and guys are flaky. i would just build the sr20 i have but in canada there isn't alot of shops that do that kinda stuff near me. i don't even have anyone within 400 miles that can tune my car. lol. here is a pic of my shelf of goodies

Do you have a 12cm2 housing? What gear are you thinking? It looks like the Boost Junkyz manifold is 1.25 runner, so 3800rpm in 3rd and 3500rpm in fourth. Full spool.

That turbo is good for over 500whp depending on boost, what are you planning on running it at?

Get that dyno'd! So people can see what the HX35 can do on an SR! Everyone I've seen runs open scroll and complains about the lag.

Here is my holset hx40 twinscroll dyno on my sr20 stroker motor. This thing is a beast!, can't wait to install my z33 trans kit, comes on slightly slower than the gt3076r but has way more top end. It keeps pulling hard all the way through.

Here is my Info and write up.. sort of dated as I did my holset back in 2006. I ran an older H1C on my KA-T and a newer H1C on my RB25.

Dyno

KA-T only made 204 hp 208tq, Ran 13.7 @ 104mph @ MIR.. at about 8 psi not nearly enough to get that holset going. Used the car as a daily drift and auto-x vehicle, was good low power fun and reliable until I left America. There is no doubt if I would have replaced the pistons, rods, bearing, better manifold and new head gasket with more boost and better tuning it would have made a lot more power. The graph looks like crap I know but we smoothed that out later as it happen to be a bad plug wire. Back then I self-tuned with a Safc and just backed the timing off. Notice in the video he was like.. "that looks better..." I was like... "......................yea......" hahah sure enough fixed it and pulled to 204.

sAhyZEX21SU

R33 self-tuned with Power FC 433chp 383whp used as daily driver and drifter all over japan still operational after 4 1/2 years of abuse!!. Great all around power almost instantly spooled and even more so when I shifted the entire timing resolution about 2-3deg on track days. Could have made more power with this setup during that dyno but had the limiter set to 6500 as I was doing some tuning in stages. and forgot to set it back to 7500.

Overall impressed with holsets and stand by them 100%.

probably 20-26mpg on street and highway , that u make big power or use a big turbo or small turbo doesnt matter , its all in the tune by having the car run at around 15.ish to 16 on the wideband when u are out of boost

Hey bud, the dyno was reading the rpm pick up intermittently so the tuner gave me this in speed, I know it doesn't help but where it starts coming on is 3000 to 3500 rpms and it revs out to 7500rpms on the top end. Just subtract 500 rpms from the top at every hash and it should give u an Idea, I am trying to get him to send me a graph with an overlay of rpms, I'll post it when I get it. These pulls were at 18 and 21psi. Stock trans with an hks gd pro twin plate, Gtr 4:08 clutch type rear end with upgraded hubs, axles and output flanges.

Your torque is insanity man...

I'm really glad to see someone getting tuned at TDC in Mobile. I'm in Bama and plan on visiting them in the future.

Care to give the specs on your engine?

displacement, cams, compression, fuel, injectors, etc. ??

Interesting. It doesn't seam like you're gaining much spool with the small housing, as you're hitting peak torque at roughly 4500rpm. What kind of boost control are you using? You're on pump gas correct? Do you know what the runner size is on your exhaust manifold?

01-21-2013, 07:01 PM

Thanks bro, mike the tuner at TDC is a boss with aem! My specs are as follows, 2.35 bc stroker motor,91mmx90mm bore, darton sleeved block, Manley I beam rods, cp pistons, arp mains, rods and Mazworx head studs with PE headgasket. Bc 272 cams, springs retainers, deleted vtc, match ported stock intake manifold and exhaust, s13 tb, port and polished head, stock valves, full race twin scroll t3 manifold with twin 44mm tial gates, hx40 pro with 12cm hx35 turbine housing from Tim's turbos. 850cc injectors, aeromotive fpr, aeromotive 340lph in tank pump. Tuned via aem. Head has dual guide conversion and revised lifters as well, itsa low compression motor, something like 8:1, running good old pump gas too, this is what limited my power, mike wasnt comfortable pushing any more for safety reasons,anything else u wanna know lmk, hit tdc up they know my car and would be glad to answer questions you might have.

01-21-2013, 07:12 PM

Boost is controlled via greddy profec 2 b spec or whatever its labeled, I haven't played with the gain or any settings on this controller so I don't know if I can pick up faster spool, I'm sure I could but its not something I care to do right now, maybe later, yes I am on 93 pump, I don't know the runner diameter, it's a fullrace twin scroll t3 flange if that helps. Oh the turbo was clipped too I remember Tim telling me it would slow spool down low but be better up top, hope this answers some questions.

RB25 HX40 with T3 .70 Bullseye power housing here.
Peakboost topmount/Tial 38mm external.
The only thing that makes these turbos at all heavy is the stock housing. Once stripped off and replaced with a bullseye, they're no more heavier than any other turbo I've used.
I'm having my car dyno tuned in the spring so I'll report back with some numbers, but it looks promising.

Hi I'm new here and this is my first post.
I bought an HX 35 last week with a twin scroll .89ar turbine housing.
It's very heavy.

Has anyone tried chopping off the waste gate casing bit and also the extended V band. There's also quite a few chunks of casting there on the housing that could be cut off too.
So
Weld closed the waste gate , cut the v band off flush with the top edge of the scroll just above the wheel drill and tap for new bolt holes.

Do-able?
Cheers

01-27-2013, 12:58 PM

Exactly!

I don't have access to a surface grinder or a milling machine so I would do it with a 9" angle grinder.
Never thought about re welding the V band on tho ... Maybe best as the metal may be as hard as the proverbial whores heart and difficult to drill and tap because its been subjected to so much heat.
If you are that far on you can also dress off some of the other chunks of surplus metal too.
Any idea how much weight you removed?
You also get more space in your engine bay with this mod.

I was going to buy a .63 housing from Tims Turbos because the original housing was such a boat anchor but. Maybe not bother now

01-28-2013, 11:32 AM

Just chopped a few of the non required chunky lumps off the casing with a 4.5" angle grinder ....... Cuts like butter
I reckon whole job done (except re welding) in about 2 hours.
I'll flat the cut off v band and the new face on the housing on a 6" wide flatbet linisher and ....... Job done

I'm running rb20 with wh1c (hx35) internally wastegated 12cm turbine housing converted to run external tial 44mm and seeing full boost at 4500 17lbs

I'm using a 2" runner tubular equal length manifold with a tial 44mm wastegate
272 8.8mm cams
rb26 intake mani
big ass intercooler with 3" ic lines
made 332rwhp dynojet and 292 on dynamic dyno

a little less then ideal for drifting so plans now are to chop the IC in half, 2.5" ic piping stock twin scroll with the thermal expansion port welded up and convert the stock mani to run external gate.

looking for full boost around 3500 but I'm not sure if this is going to happen or what were going to see. Anyone else running semi same setup out there on a rb20?

Oh and my hx has quite a bit of shaft play I wonder if this is also detrimental to the spool time?

Also another idea I was contemplating was building a spacer to come off the stock manifold to make the twin scroll stock manifold merge into a single scroll and block one of the scroll ports on the holset. I am only worried about this causing too much back pressure. It did happen to come off of a 5.9L so one would think that they could get by pushing a 2.0l through one port . Blocking off one side of the turbine will make it spool very fast, you are essentially cutting the AR in half.

Here's what I think you should do:

Fab a 1.25 runner twin-scroll manifold, use your single gate, and move down to 2.5in intercooler pipes. This is really the only way to get to your spool goal while not choking the top end. With those two parts, you'll have a much larger powerband, and have the ability to make more power than the stock block can handle.

i have an hy35 on a ka, starts boosting around 2.7 and full by around 3200. works pretty well imo. I do have an extra hx35 if anyone needs to experiment, just pm.

I am confused when I read some body say this.

What does it mean to say start boost at 2700 and be full boost around 3200??

Is it like you feel turbo power at 2700 and ends at 3200?? What happens after 3200, theres no more turbo power?

Or

Is it like your turbo starts to build up pressure at 2700 and reaches full pressure 3200 then you feel turbo power from 3200 to red line , per say.

Sorry for the basic vocabulary and new to the turbo game question. (Don't like the word noob)

I'm looking to boost a stock rebuild ka24e with a Hy35 or similar.

I had a friend tell me if I wanted to be gas efficient to get a turbo that doesn't start spool till 2700-3000 rpm. Can somebody explain this to me. Thanks in advance

Hard to tell on the pic but is that a T3 or T4 frame housing?

DO you mind sharing where you got it? I'm considering something similar in a T3 Frame. Thanks!

Not at all... it may not help much, but Alamo out here just rebuilt the turbo and told me it was a hybrid of "some sorts" lol...

The serial tag reads HX40R, yet, I can't find any info on it, not even the housings

Thanks! I'm just checking my housing options if it's worth the trouble switching them out. I currently have both 60mm Compressor Holset turbos while it's not really an issue to run TS turbo on a NON-TS turbo manifold It would be nice to keep it the same if cost is not too bad.

Stock rb making 300-350wtq? Likely 20+psi out of that turbo to get there... cams are likely a wise choice as well.

The turbo should come with a restrictor, if not, call holset or do a quick google... Go with stainless lines to make life easier.

Got a stock rb25 s1 planning on using the stock mani with ext WG flange welded near the turbo flange planning on using 7-blade hx35 (90k miles on turbo) any suggestions for how many psi I should run for 300-350wtq? Any advice, suggestions,first hand experience, also do I have to run a oil restrictor on this turbo or should a normal oil feed line suffice?

These turbos don't really wake up till after 25psi, but I'd imagine a big engine like an RB could make 350wtq at 20psi.

A normal oil feed should suffice, but you might need a .8 restrictor if your oil pressure goes above 80psi or so at maximum rpm. Also make sure you run the biggest drain you can fit.

I bought two HX35s recently ... one with a 7 blade comp wheel and the other with an 8 blade.

Is there any difference between the compressor housings on an 8blade vs a 7blade or are they completely interchangeable?

Cheers

They are NOT interchangeable. a 7-blade wheel has a smaller exducer and bigger inducer on the compressor wheel.

Also I notice that the CHRA on the 7 blade one does not have an oil baffle plate and has a pepperpot oil slinger instead of a plain one .... I know these internal parts aren't interchangeable but is one style better than the other?
