limits of gsr stock internals
what is the limits on whp for a stock internaled gsr? my motor has about 24k on it and im puttin 160 to the wheels now, hopefully 170 at the end of the week. i am considerin boostin her, but if the stock limits are only gonna net me another 30 whp then i wont do it. i dont want answers like boost till she blows or anything like that. this is my only car so cant be doin that.

Im going to be putting down 220whp @ 6psi on stock internals on my b18c1 with a t3/t04e. I have seen Jeff Evans tune a stock b18c w/ skunk2 intake manifold for 360whp on stock sleeves and internals. Now of course even though that motor is well well well tuned, its gonna let go eventually because the internals can't hold the extra pressures however I have seen 10psi on well tuned stock engines all the time.
My co-worker has a 1998 Type-R with 112k miles, the engine has never been opened and hes running 9psi on a crappy FMU and pump with a Turbonetics T3 a/r 48 turbine .42 compressor. Hes been boosting for the past year and a half, we go to New England dragway about twice a month and he puts about 6-8 1/4 mile passes every month. His car is not puffing smoke, doesn't burn or leak a drop of oil, and a recent compression test showed:
cyl1:220psi
cyl2:215psi
cyl3:210psi
cyl4:220psi
He hasn't done a leakdown, but its not burning anything. Just goes to show ya, you can run a good amount of boost on any honda engine. Hes going to Uberdata and going to try 12psi.

I have seen well over 300 whp on stock internals, so it really isn't a problem with the amount of power you are looking for. Most of it is in the tuning, but anything more than 300 whp is really stretching the structural limits of the internals.

stock internals lol.. they rule.. i just tuned a b18c turbo running a percision c50 turbo, at 5, and 7 psi.. its sick son.. it spiked boost to 11.3psi at one point and it didn't do anything damage.. even raced a SC 350z on that 11.3 untuned boost and whipped his ass.. stock internals as shmoo said are compiable of handling up to 320 WHP..the only major thing to really upgrade on a gsr is the rod bolts, head studs really other then that man u can run 10-12psi all day long.
