what’s the max boost you can run on a completely stock RB20 set-up without detonating the engine? like, would i be safe raising boost a point or two?

How are you running 7psi? Completley stock I have been running in excess of 12psi. With the SMIC and even now with the FMIC.
ALL stock.
Had a bc on it, pushed her to 16psi, heard detonation, back her down to 14psi. Then learned about ceramic turbo’s blowing up over 14psi. Back to stock. leave it alone lol. 10-12 psi is good.
Watch your a/f’s though. Get a wideband.

i’m rockin’ a wideband already. i thought the stock boost was 5 lbs on these, but my gauge is telling me 7. possibly an aftermarket wastegate then? well, i should be good for 10-11 psi then i guess.

No man. My shit is all stock lol.
RB25 had regulator for 7psi iirc.
Maybe you have RB25 turbo already? With RB25 regulator?
Supposed to change the RB25 regulator to the RB20 regulator.
