turbo details and compression for b18c7 question

[votek]

i have recently bought a 2.6mm headgasket for my b18c7. worked out by a known mechanic, the compression will be 9.3

im running a custom turbo kit with a t28 ball bearing from the jdm s15. what would the max psi / boost i would run on my stock motor?

[Q_ball]

Dude, seriously, there's no definite answer to that...
Ive seen stock motors take 12psi for months on end.

All comes down to who you're tuning it with, and with what etc etc.

Yeh, too many variables man. Setup, tune, how you drive it.

damn this is a hard one.

How high does your boost controller/wastegate go?

that im not to sure. i have a electronic boost controller. just im asking because sr20's with 8.5 compression run up to 15psi with this turbo.. my motor now a 9.3 compression. will it hand at least 10 to 12 psi daily drive

Doesnt work like that..

IT IS ALL ABOUT THE TUNE

Like Q-Beezy said, with stock internals DL001 was running 12psi?

And it could possibly even handle up to 16 depending on how it has been tuned. There was an article about this on honda-tech a while back..

ive ran 9 psi with stock internals and stock head gasket,

like they said its all about the tune,

if they get the proper air/fuel ratio in then it should handle 10-12 psi

[DLO01]

Na man. I am about 8.5 psi max.

Like I said there is no exact figure. Depends on setup, tune and how you drive....

i'm running 10PSI on a stock build.
heard with a HKS decompressed head gasket you can run up to 16PSI, there was a car running this tuned by Toda.
Maybe PM him and ask.

But it all depends on how long you want it to last.

It's unreal to think just a head gasket can make such a difference.
