well the budget says no pistons are allowed . So it looks liek the f20 will be using the stock 11:1 comp .

i was thinking of making 400whp at some point down the line so i want a turbo that will keep mr goign for that. i know that 400whp isnt gonna happen on the 11:1 reliably . if i went with a t3/t4 of some sort (sc61/ t3/t4 turbonetics ect) what the max boost i would want to run .

ill be tunnign with crome and im gettign 650 to 750 injectors (mabye over kill but i dont want to have to buy them again down the line .

i might be able to get away with a thicker head gasket but i dont really want to crack open the motor untill i can at least do pistons .


how long have the stock type R guys held up ?

 

i know i wouldnt boost on 11:1...

 

type r guys can get away with it , and s200 seem to do ok on stock , im not after insane power just what ever i can get away with .

 

with the stock pistons thats allot of power/heat/stress to put on them. how long you want the motor to last?

there are lots of guy making decent power on high compression+boost but it's all in the tuning. you need a good EMS and some good high octane fuel.

i would strongly suggest getting some forged pistons and bring the compression down to around 10:1 or less.

 

Use race gas.

drive that **** on C16

You may look into a HG shim...it fits your budget and would save you a lot of headache. I would personally go with a large(r) turbo... T4/60-1...T4/T67

 

Is this your daily driver? If it is and you will be on pump gas then lower the compression to like 9:1. It will be much safer.

 

he has to keep the stock pistons.

 

That sucks.

head gasket shim. problem solved

 

you should be alright if u get a good tune, i would get hondata or uberdata, f*** an FMU

 

no fmus i hate them . ill be runnign a 255 walbro and i have crome ,awaiting crome pro.
im pretty sure i can make it work , and im no tlook ing for things to last the for 2 years
mabnye not even one year .

i just need more time to save up . id rater not get pistons now and save up to sleeve and bore to 87 0r 89mm and keep the 88mm stroke , i think it would be a great combo . but

can i get away with a full point lower with just a gasket ? reliably that is

Couldn't have said it better^^^. Just make sure that when you are tuning it you are reading the plugs. I had an 11.5:1 setup w/ boost on top and it would start to detonate on anything above a certain power level on 93(timing taken out as far as possible). I ran it on 110 oct. and was able to go much higher w/ the power but, still had to run crazy conservative timing. Good luck and don't be scurred

thats the way i see it . but what kinda boost should be run , i dotn plan on going over 6-7psi and ill make sure i have more injector then needed and ill go easy on the timming

 

F20 = Iron sleeved you will be fine

 

thicker headgasket
race gas
real good tuning
it's very do-able

 

yup thicker headgasket .060-.080 should do it

What power level/boost/turbo was that? And what was your motor setup and what were you using for tuning? Did you feel this setup was more responsive than a lower comp setup? What did you think of it for the street on pump gas overall? After running that compression with boost on pump, what would you choose ideally for the street on pump for best response?

 

You'll be ok. I was runnign a JDM ITR stock motor 11.1:1 compression on Hondata S200b dyno tuned. I made 307whp/208tq at 8-9 psi on a T3T04 57 trim. It was awesome! I drove it for over 6 months. IT DID NOT BLOW! My tranny went out and decided to redo my set-up for more power......

 

I ran about a year on 11.5:1 JDM ITR with a t3/t04e at 9psi with hondata and a conservative tune pumping out 280hp to the wheels. It had slightly lower compression in #3 cylinder before I boosted it...so it was only a matter of time before the ringland cracked on #3. Im rebuilding now, I probaly would still be driving it if the rings werent week in #3.

 

nice , thanks guys .

what a/f should i be tunnign for for safty . i was thinking 11.5ish but im not 100% sure

About 400whp worth of fuel was being used, Boost pressure was at 13psi and the turbo was a straight T04e(.80/.70). Motor was, piston and rod GSR(11.5:1 SRP's). The motor was not noticeably more responsive than a 9:1 motor. On Pump I could only run about 9psi (injector calc. said 325whp worth of fuel) before it would start to show signs of detonation on the plugs on 93oct. I will NEVER build or use another high C/R(over 10.5) setup for boost. It was a bitch to tune and I only used it because it was what I had. I'd go w/ 9:1-10:1 regardless of Purpose (Street to full race setup). Nothing lower than 9:1 on the street though. Just my .02 on the subject.

No joke..A guy in town here makes 400+hp on a stock compression ITR motor, as far as I know it is still running

 

call inlinepro.. they will help you out... a friend of mine used there thick head gasket and ran 18 psi with a gt35e on pump gas and made around 430. stock S2000 motor

 

what thickness of gasket should i be looking at
