18g and 20g turbo users

[s13silvia123]

i would like some info and share some info on what could benefit each other. i know that there isnt too many guys who are into these turbos but i've most people go after the garret series of turbos. i would like to see more people who uses mistsubishi turbos and their thoughts

please post your engine specs

1. your motor
2. motor specs
3.turbo size 18g or 20g turbo, etc.......
4.fuel injector size and brand
5. tune or untune
6. engine management system

i'll add more when i can think of more

When I first got the car, it had a Greddy T518Z turbo on it. S15 Spec R engine with 550cc injectors with a rom tune. Changed the injectors to 850cc SARDs and PFC, figured turbo was pushing close to 350hp. Compared to my GT2871R in the states, setup wasnt smooth compared to it. GT2871Rs has a more linear power band, T518Z was more like an on/off switch.

The beauty of the Mitsubishi turbos are that they're rebuildable. $80 for the rebuild kits.

I know a couple of folks out here who run Mitsu turbos. With the 20G, one guy made about 380-390 hp and 2 guys were running 25Gs. One made 460hp and the other was at 485hp.

[s13silvia123]

thanks for the info dude i would like to see more poeple who has these turbos

[deukalionS14]

i was looking into the GReddy varient of the TD-06 20g turbo too...I need info on this thing! lol

[s14unimog]

1. s13/s14 Hybrid SR20DET
2. Engine Spec list:HERE (http://zilvia.net/f/chat/221815-96-zenki-slight-overhaul.html#post2413955)
3. FP TD06SL2 20G
4. Nismo 740cc / 300zxtt fuel pump
5. Tuned
6. Nistune

Due to, what we believe is, a problem with the actuator opening prematurely, my graph looks to be that of an N/A platform. The car spooled slowly and ended up spiking to around 17psi with no boost controller (using the 1bar actuator provided with the turbo). These are the results. I'm currently in the process of figuring out why its spooling so slow...:wtf:

Couldnt find any TD05-18Gs on ZY, I had a Greddy T518Z that was basically an 18G. Comparing it to my GT2871R in the states, they were putting down about the same power (roughly 350whp). Only difference between the 2 was the power delivery. GT2871s, power came in more linear/smoothly. T518Z, it was more like an on/off switch. Nothing before 3.5k-4k, then full boost of fury that I'd loose traction like crazy. I wouldnt recommend it for drifting since itll just make you spin out when the power gets there.

will the Greddy T518Z TD05 18G 10CM turbo bolt right on re-using the oil feed and oil return line/pipe from my GT2871R? Or will i have to piece Banjo bolts or fittings to make it work?

[S13 curtis]

You know what, it makes more sense for people to buy evo8-9 turbo's because you could get the turbo for about $250 bucks on the evolutionm forum and make the same power as a gt2871r for a fraction of the price. just purchase the flanges that are really cheap to get and have some one weld you a kit.

@TS i think you will prolly be better off pieceing it togeather from a hardware store that sells that stuff.

oil feed fitting is different, i'm using a -3 an fitting i think its been quite a while now but as for the the rest they all fit

[TSLegendary]

I installed the (rebuilt) turbo, and after being mis informed by the seller of the turbo, the S14/s15 return line didn't work. I ended up having to use the Mitubishi return line, after he insisted that the OEM nissan ones we're compatible. Long story short im stuck with a turbo with no shaft play and but smoking under boost. I used the Gt2871R line but with a 10 x 1.25 banjo bolt and banjo fitting. This is horrible, made me wish i just bought a new GT2871R then would have bought this. By the way thanks for responding guys.

[s13silvia123]

for the oil return line for my turbo i'm using a t25 return line with a rubber hose.

Nice job. E85 makes such a difference. You must be just about maxing those 1000's out at that power. Time for 1300's and 30psi.

[TheRealSy90]

Has anybody ever ran a Greddy TD06 20g 8cm on the stock manifold with t2 turbine housing? Thinking of doing this to go back to a stock manifold setup. I hear a rumor that the 20g on a t2 turbine housing would restrict it's capability by about 50hp but idk about that since the stock manifold is proven to support 400+hp, which is the upper limit of a 20g.

well there was a guy on here with a fully built KA and a greddy 20g 8cm t3 made 400whp on e85 and 26 psi

[Tom N]

Made 520hp with a T2 20g on 22psi with E30 and alcohol injection.

[s13silvia123]

made 380hp 18psi on 93 on a Greddy 18g 8cm T2 with custom 38mm external gate megan manifold for a fact i know it should make more on E85
scraped the idea and went twin scroll GTX 3076R after oil seals on 18g went out.
i still have the kit just laying until i rebuild the turbo.

[TheRealSy90]

Okay cool. So since I don't even want over 400hp it's definitely capable with the T2 housing. Now i'll have a greddy 3 bolt, t3, and t2 housing for the same turbo haha.

Figured I should post it in here since I finally decided on my setup. Sorry the picture is large.
Still putting everything together but I'm hoping to have it all done and get the setup tuned on both pump and e56 by early 2017.

I'll be using the Mazworx kit with a GkTech shifter.

I've got the Comp twin disc and it's an awesome race clutch, but at a reasonable torque level especially within that of a 20g or even bigger...I'd seriously consider the spec stage 3+ for its holding ability and much smoother engagement potential. The twin disc grabs like trump and shifts fast as lightning, but it's not very friendly cruising around town. I haven't used the stage 3+ yet, but I may swap to it sooner than later. My older act held the 20g no problem and had a lower rating than the 3+

I have a Competiton Clutch stage 3 ( 6 puck ) and it's holding close to 500TQ. It does engage very high though with minimal slip. Very grabby. But I hate twin disks.

Not a very necessary mod for a 20g unless your trans is already fucked.

You think a stock SR trans will hold up very long at 550hp?

[TheRealSy90]

It won't hold up lol. The mazworx kit is great except the shifter relocation isn't far enough forward unless you don't might trimming the hole a bit in the chassis. It will clear the shifter trim though.

I doubt you crack 500 on a chassis dyno, but I guess 450 is starting to push the SR trans. Mine lasted a couple seasons at that power, but I was smooth on it so i guess it's probably worth the CD009 if you've upgraded everything else. Both of my mazworx kits work flawlessly.

Made 520 on Zfevers dyno jet at 22psi. At 30 psi it's topping 550.
The SR trans isn't going to last. Haven't even run it past 20psi yet at the track cause I know it's going to break that trans.

[600supersport]

[TheRealSy90]

Finally got it all put together. I got Inconel studs for the t2 flange from Flyin' Miata, these are supposed to be stretch proof so that the gasket doesn't blow. Combined with the Stage8 lock nuts I'm hoping it stays leak free for a while. CodyAce Tial MVs manifold. Kinugawa td06h t2 8cm turbine housing with gate welded shut. Mazworx studs and nuts to the head.

It's only the one oil feed line. Unfortunately I can't find any local :/ are they not durable enough without it?


Sent from my iPhone using Tapatalk

[600supersport]

The cast manifold won't be as detrimental as a tubular manifold in this case and your oil line isn't even close to it, but you are worried about flange bolts stretching so a few inches of shield won't hurt, but isn't necessary.

I'll definitely get a piece on there before it's ran for any significant amount of time. The 90° where it goes to the turbo is actually really close to the flange, like 1/8" to 1/16" from it. Really needs a banjo there but don't have a line like that unfortunately.

The studs to the manifold definitely do stretch under track abuse, mostly the grip racing guys that are on track for extended periods of time have that problem. I'd just rather not risk it. However the studs to the 5 bolt flange are just regular FRSport brand.

Just did a little upgrade on my TD06H hotside. From the 11 blade wheel (312 grams) to the newer, straight 9 blade wheel (193 grams). I expected weight savings, but that's almost 38% less, not to mention better flow.

What kind of power can I expect from a TD05H 18G? I picked this up over the weekend to run on my SR, motor will be stock compression, tomei 260 cams, stock SR manifold w/ ewg and E54.

Also, can anyone tell me what A/R this exhaust housing is? Would throwing a billet compressor wheel in it make any more power? Got this thing for so cheap I wouldn't mind spending some cash to update it a bit.

You could reasonably make 400hp on it. If you're one of those who knows how to extra all a turbo can do then you could get 450.

Yes a good billet wheel will make a little more power. A billet when that's the same inducer/exducer will have a thinner center and typically be taller. This makes for a larger blade surface even though inducer/exducer remains the same. Larger blade surface will add few extra lb/min airflow potential.

Don't know the a/r of that turbine housing.

Interesting, wasn't expecting it to be able to make that kind of power. Really glad I decided to pick it up now, should be a fantastic little turbo to run for a bit. :hsdance:

he's right. you can also change out the intake housing and convert it to a 20g with a 20g intake turbine.

450hp is possible if you take all the necessarily steps.

Well technically it's my daughters car. I'm just the builder. Motor is out right now. Stupid timing chain oil squirter popped out. What a great design there Nissan.
Have the Mazworx screw in one now. Going to try and get to doing that this weekend and put the motor back in. Hoping to see 550 rwhp on this same tired 20g with the new bigger injectors and Haltech. No more stock ecu.

I have a Talon.

Are you on a billet wheel 20G?? I see the connection now between the Talon and your hankering to run the 20G :)

And to be fair, Nissan never thought they would be seeing a 300% increase in power when they designed the stock timing chain oiler lol!

Yes. TD06-SL2 w/ billet 7 blade 20g compressor wheel.
This is an amazing street turbo. Spools fast and doesn't stop pulling till 8k rpms.

I don't see how horsepower affects the timing oiler lol. Just a bad design that can pop out.
You should be able to see a number inside the turbine inlet somewhere that says what size it is. My 8cm 20g had an "8" cast into the turbine housing somewhere.

There is an 8 on the inside of the turbine housing inlet, probably safe to assume its an 8cm housing.

Yep, 8cm turbine, which is good. Best size for a response setup.

Okay, so I have been thinking about what I want to do with this TD05 I picked up and I think I am going to grab a 20G billet wheel and housing. If I bought this, I would just need to swap the wheel and housing and I'd be good to go, right?

20G wheel and housing (https://www.ebay.com/itm/MAMBA-5200-3-TD05-TD06-20G-Non-Anti-Compressor-Housing-GTX-11-0-billet-wheel-/262950705325)

Also planning to rebuild the turbo while its apart, are there any rebuild kits that you guys would suggest or just buy any random one and I should be good?

Yes.

I would look for the KTS 7 blade billet wheel.

Yes.

Why that specific brand? I have read that the 7 blade wheels can make slightly more power, but I think I'd prefer response over the extra power.

I have also been looking at 9 blade turbine wheels, seems like they weight significantly less, offer better spool and helps hold boost in the higher RPM range. Would it be worth moving to one with the 20g compressor wheel?

I paid next to nothing for this turbo so if I can spend around $400 to make it capable of 400whp I'll do it.

The 7 blade wheel just works.

A standard cast 20g turbo is good for 400hp.

Fair enough, if it ain't broken don't fix it.

Any input on the 9 blade turbine wheel vs the 12 blade? I'll probably snag this one because its a drop in for my TD05H

No input on the 9 blade.

I tried the 9 blade in the TD06H and felt absolutely no improvement to the 11 blade in spool with the lower weight, it only seems to have worse efficiency so at best, the same spool as 11 blade and maybe a cunthair more top end flow, but I wouldn’t bother with it. Get KTS 7 blade compressor like Tom said and have G Pop Shop do the machining and balancing.

G-Pop shop is the way to go for a quality rebuild. Mine came back looking better than new.

[tb13]

Got some parts today and got to work rebuilding this thing. Couldn't find a source for the KTS wheel you guys suggested, so I got a compressor wheel and housing from Turbo Labs of America along with their rebuild kit. Everything fit perfectly, little heat from a blow torch let me slide the wheel right on. Also got some new studs for the turbine housing to round it all off. Super excited to hear this thing and see what kind of power it can make.

That wheel from turbo lab is a KTS wheel. It's what I have. Made 565hp With it.

[Danscomp]

I've read something about needing to balance the rotating assembly after you replace the wheel. Any truth to that?

[600supersport]

People have had luck not doing it, but for <$100, it gives me a little more reassurance because small imperfections can become large vibrations when something is spinning well over 100,000rpm especially if you’re pushing high boost levels. I’d rather not spend a bunch of time cleaning aluminum out of my charge pipes if I don’t have to.

The billet compressor wheels are component balanced. So it's not 100% needed to balance the whole rotating assembly but it's not a bad idea either.

Have you been on any other dynos Tom N?

Been on 2 different Dyno jets. One at Fever racing and one at Ztuner.
Both were about the same. Car has only gone down the track at around 400-420hp level so far. Needs some drivetrain upgrades.

I posted a dyno comparison from when we switched from a standard cast 20g wheel to the 7 blade billet wheel awhile back. I would have to look it up but at 15psi the Billet wheel made like 30-35 more hp if I remember correctly, with it being the only change. That wheel has a much larger face surface on the blade and flows a good 3lb/min more air than a standard 20g wheel. While still having the same inducer/exducer measurements.

Well sweet, that is some really impressive power from a turbo this size. I'm sure my 18G turbine wheel will hold me back a bit.

That is a really impressive gain for just swapping the wheel. Would be interested to see those graphs if you've got them handy.

There's no such thing as a 18g turbine wheel. If you mean a TD05h turbine wheel then yes it won't make as much top end power as the TD06sl2 wheel we're using. But it will spool faster.

I'll try and see if I can locate the graphs. It was close to 2 years ago we first swapped to the billet wheel.

This is going to be fun :2f2f:

Hey guys I've been doing some research on the turbo I am going to be running. It's one of the new Tomei MX8270's. On paper, it has the same exact specs as a td06h 20g. I am unsure what wheel they are running, all I know is that it looks like a 6+6 blade billet wheel.

Has anyone ran this new turbo?

Am I going crazy or its pretty much the same thing as a 20g lol. Below are the specs maybe you guys could tell me your thoughts?
