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

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..

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...

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

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....
