stroker kit being done and turbo is tiny

[whereda40at]

i have an sr20det and i am gettin my stroker kit done as we speak. (brian crower 2.35L)

i have an hks 2530 .86 a/r turbo on the car now. and i cant realy find anything about anyone with this set up. im trying to find out what the turbo is good for.

i dont care about streetabilty cause it is goin to be a track car. i was thinking of the garret 35r or 40r. but dont know what is best.

any help would be great

[steve shadows]

hks 2530?

eh.

go garett

or maybe a T04Z.

I mean how much power do you want?

A gt3076R with a .86 would be fucking retarded.

Youd be in the 480whp range at 20 psi of boost with the right tuning and supporting mods, even on 93 oct

I still want to do this before I move to BMW one day.

Do the 2.2 or 2.3 liter with a .63 ar sr20det or a .78 ar ts gt3076r.

Run 25 psi all the time on 104, 500whp+ with insane response.

[whereda40at]

well what turbo would get me at 600whp. that is realy my goal.

[DrIvEsldEwAyS]

gt35r would. my buddy running pump gas and 21 psi on 2.0 and makes right at 500

[hooflungpoo]

here is a chart on turbos, maybe this will help you out...this is an estimate tho so dont quote me or use this as a factorial guide...also hp #'s depend on what motors they are applied to

[whereda40at]

ok and with the stroker the lag would go away.

what kind of power can i get with the hks cause i cant get the bigger turbo yet cause i have to save up money. (still payin on the stroker)

i have all bpu and greddy intake mani, hks step 1 cams and e-manage for tuning.

also before i get the new turbo i have to get axles.

[hooflungpoo]

u could probably get anywhere from 350-450 with a very good tuner? i dont know those turbos well but that would be my guess...sounds like u have a long time before u put a big turbo on there ;]

you definitely need a bigger turbo with a stroker kit...more displacement spools bigger turbos up faster, and that my friend is room for tons of power

[whereda40at]

yea prolly wont be until march or april cause i have to get new axles and drive shaft and maybe a tranny. so its being built slowly.

i just want to know what ill be putting down with the turbo im running. the people i have doing my tuning have the worlds fasted dsm (1081 whp) extreme motorsports. they are realy good.

[sr20boostn20]

im running a turbonetics gtk 550, a big t3/t4 it got me to 491whp @ 18 psi, i have terrible lag tho, its a drag car.

that turbo on a 2.3 l would definitely be good for over 600whp with a lot less lag

[qt_240]

gt35R to me would be a good set-up

[SlidewayzS14]

How will the stroker get rid of the lag? wouldnt it increase it due to the longer stroke?

[PoorMans180SX]

You need to read up. More displacement means more exhaust gases coming out of the cylinders, which means faster turbo spool. I could get into a lot of technical stuff, but you can find that yourself.

For the original poster: I wouldn't expect more than 350 with that turbo. You'll have zero lag though.

[whereda40at]

ok cool thats what i was looking for. so then ill just get the turbo kit then ill get axles. if it aint broke dont fix it.

could i get more power out of that turbo with race fuel and more boost

[steve shadows]

ok and with the stroker the lag would go away.



in fantasy land.

You will still have lag and considerable lag with a gt35R on a 2.2 liter.

It will just be less lag than a 2.0.

- why do you need new axles?

Stock ones are fine and cheap and work to 600 whp.

and tranny? You mean Z tranny?

are you brainstorming or just talking about this in a pipe dream?

Pipe Dream if it wasn't he would already know what he would be getting if not... stick to what he is saying .. the pretty much the basics for 600..

[redtop91]

Ummmmmmmm no?

[Creizai]

BC has a 2.35 Stroker do it do it

[Koopa Troopa]

I don't know why people like ruining the perfect 86mm x 86mm bore and stroke the SR20 has...

[redtop91]

Their friends told them the the only way to make power is to up the displacement, and they assumed it as fact, either way it is misguided and airflow is far more important. And you EGT's will go up by using the same turbo on a large displacement motor. I wouldn't consider a stroker until I was over 600whp.

[whereda40at]

well i have been lookin up turbos and such. still have not found a simular set up that im goin for on a dyno sheet.

im only 1 month away from gettin the car back together. just waiting for the machine shop to start the block and we will be good after that.

i have a friend of mine who is makin 430whp and broke both of his axels. thats why im getting new ones. why would dds sell 600whp axels if that is was stock hold.

i cant find anything about borg warren turbos. i have been on there website and didnt find what i was looking for. anyone with a set up yet or no?

[johngriff]

BUY A GT SERIES GARRET TURBO. They make LOTS of stuff that will fit your needs.

Get RID of the emanage. You will find me as a propenent of the cute chrome box here allot.

But not now. The injector size will be WAY too big to tune via +/-. So you would have to set it up in "Total map mode" Then, for that much power, you will have way to LOW of a map resolution (16x16). Additionally, your injector phasing is going to be so out of time compared to the stock sr.

These issues disqualify the PFC. Too expensive of an engine to risk a MegaSquirt on.

You MUST buy:
HKS FCON pro (and have Tanaguchi tune it)
Haltech
AEM
MOTECH
TEC III
WOLF 3D

That is IT.

Dont say they are out of your budget, because you are spending allot of money, time to NOT cheapen out.

[Prok0]

Yeah, I dunno about the BC stroker kit.. IMO if you want more displacement, have new sleeves installed and go 90 mm bore and stock stroke that way you have added displacement without sacrificing revs. Comes out to around 2.2 if you go 90 bore and stock stroke. Enjuku runs that setup on one of their race cars.

[whereda40at]

well i havent still seen a set up like what im goin for. i want to know what the spool will be on a 40r or 42r.

sorry dont mean to sound ingnorent but i dont realy understand what you are sayin can you dumby it down a little bit for me.

[johngriff]

40 Series is LAGGY.

IE: "TeamPacMan" built a similar car, that was very thorough with a 40R, made less than 500hp with so much lag he parted the car (someone here owns the chassis now).

[whereda40at]

what about a 37r or a twin scroll?

also i didnt do the sleves and just get rods and pistons because my crank was messed up and it only made sence that the motor was goin to be apart i was goin to do it all instead of doing it twice.

[johngriff]

3037r? Thats an ok turbo now, but its been overshadowed by the 3071r because of its much faster spool.

What type of racing will you be doing?
:-D

[whereda40at]

drag 1/4 mile

[Prok0]

sorry dont mean to sound ingnorent but i dont realy understand what you are sayin can you dumby it down a little bit for me.

If you are looking for added displacement to spool a turbo a little quicker I wouldnt stroke the motor, I would install new sleeves and bore it.. That way you still maintain the stock stroke and can still rev high..
Because if you go longer stroke you wont be able to rev as high so it will sort of be pointless, you may spool the turbo quicker, but you have a lower redline, and therefore about the same powerband..

[whereda40at]

sorry i ment what johngriff said i under stood what you ment. sorry bout that. but the kit will be here in a day or 2.

The operating range might be similar, However the torque and HP numbers would be larger.


I would recommend a gt3582R or a 3076 R, depending on what is more impoartant to you, response or big numbers.

*edit*
For drag, probably a 3582R... that is the set up I am going with.. only instead of increasing the stroke I am increasing the bore and building it for high rpm runs....

[whereda40at]

would a 37r be too laggy or know. cause like i said its for drag and lag is not realy a proplem here. as long as it makes up for it in the long run.

[johngriff]

No as long as you have an adequate staging system, like a two step or anti lag.

[steve shadows]

40 Series is LAGGY.

thats because it was a 2.0


2.3liter should spool a gt40r with a .82 housing the same as a gt35r with .86 t3 housing, maybe better.

GT40R wheel is great, but I would suggest solid lifters.

Then you run in calcin max piston speed and oil pressure needs to compliment your 9k power band as well.

sigh, so much money.


hence i stick with 86 x 86 like koopa was mentioning.

Raise the compression, use a 500whp turbo that has a power band, it will be faster on the street, strip and canyon than a gt40r car with 600whp and 2.2 liter in most all cases.

You can rev an sr to 8500 with a stroker kit and propper oiling.

its when your seeking nine, you need to take bearing clearences and oiling into account (like custom clevite maybe) etc.

mazworks does 10k... and 9500 shifts on a 2.2 liter latey, Hybrid doing 8500s all day with stock oiling system iirc

[whereda40at]

well the kit will be in real soon and then the block goes out to get machined. right now im lookin for motor mounts.

but im still leaning towards a 40r cause to run in the class that ill be running in at the track. you have to be in the 10's to be a threat.

im also lookin for a rear set up. still doin alot of homework but i have time. cause money will not be there for all of it at once. so i have time to learn. and im sittin in the front row of the class with my notebook. so teach.

[PoorMans180SX]

Definitely get a twin-scroll turbine housing, whatever turbo you choose, and a split manifold.

^ HYPE ALERT ^

haha, I want to try one myself, but from what I know, Its not going to make a night and day difference.

many have reputed that.

It does make A Difference, but its up to the buy to decide if the transient response (which is the only improvement) is to be worth the extra money.

[whereda40at]

what does a split manifold do for me?

[steve shadows]

According to Full Race and people who shelled out 1400 dollars for the manifold it bends time and space.




honestly it's suggested to divide gas pulses up between odd cylinders allowing for better flow, for better transient response.


Some also think it makes mid range torque increase, but this has only been demonstarted in a couple of cases and makes me led to believe it was just a change in boost through that range of rpm due to less more back pressure in the system

[whereda40at]

ok so to put this tread to an end. here are the conclusions i have come to....

1. a gt40r .82 a/r is not to big and would not be laggy on the stroker kit.
2. can rev up to 8500 rpm
3. full race manifold is the way to go for easy intall and power and reliable
4. the 300zx rear is a must and will be done asap.
5. need a 2 step or anti lag system. which one?

[daryl337]

In all honesty... although a 2.2 or 2.3 liter motor would be able to spool a gt40r... I think that a 3582R would suffice for you until you really are going to shell out the cash... because the operating range of a 3582r would give you less of a spikey powerband (albiet it will still be spikey).. and is well enough to get you into the 700hp range if you tune correctly and use race gas.


But then again, I dont know what kind of money you are playing with, because I could tell you a sweet set up if you are willing to pay for it.


I myself have about 4 thousand dollars worth of new car parts in my bedroom waiting for me to shell up the other 4 thousand for parts for me to finish the job. :)

[whereda40at]

well time is money and you have to play to pay. i just have to make sure i have everything else before i go big. like get my drivetrain straight. im on stock drivetrian with a stage 4 comp clutch and flywheel. i know the axels wont last and that i will need a new tranny soon. its all a matter of what breaks first and what i have to do to fix it. so my tranny is prolly next and i already know what i want for that. im getting a dog box for that.

[toy215]

i'm at about the same stage you are at and would like to pick your brain give me a call. i pm'd you... hks 2.2L stroker kit with sleeves greddy oil pan, port and polished head, match ported greddy intake manifold and throttle body,tomei 270 intake/exhaust cams, BC +1mm valves with 5 angle job, tomei double valve springs, tomei solid lifters, 550cc injectors, running my s15 turbo, and a blitz FMIC for now also. oh and a toda flywheel.

i still need to get bigger turbo, 1000cc injectors, new clutch kit, and engine management. thats just to finish the motor. car it self has a long way to go so i know how you feel!!! actually i know how your wallet feels....

[whereda40at]

i had been lookin and talkin to people and i think im goin to get a borg warner 366. it spools as fast as a 35r and had the power of a 40r.

the 366 has a much better flow rating.
