Sr20blacktop

Hey I purchased a 240sx a week or so ago claiming to make 240-250whp

. It's running a greddy (?) exhaust, stock blacktop turbo, K&n air filter, apexi standalone, maf deleted, bov, fmic, etc. Anyways I believe it's on the stock fuel system. currently running 8-9psi of boost. Is there more room on a stock motor for more boost? 10-12 psi or is that asking for trouble ? What size injectors are needed to make more power? Any other recommendations?

If it is an S14 engine with the S14 JDM Ball Brearing unit you can safely go to 12psi. More is possible but it will wear the turbo out quickly, especially if you had a shitty bypass.

Its on an apexi stand-alone unit, so your best option for more power is to install 740cc injectors, and a GT2871r or similar turbo, for a 320rwhp on stock cams, or 350-370rwhp with a set of upgrade cams (S3 JWT I recommend for OEM springs)

I was told it was a s15 black top with s15 turbo , i believe since it's a swap I may only have the ka24 fuel pump
