How much boost will a stock '02 engine take without sacrificing reliability, and how much power would it add vs stock? Thanks.

 

40lbs with out new head studs. Just a GUESSTAMENT

 

just adding boost to add boost won't do much for you unless you're adding fuel to the equation... you probably won't be able to increase your boost much without the extra fuel anyhow.

 

Yea what graphit said. Gotta have that extra fuel added in. You have a hy-35 which ive heard from a few places and people you shouldnt go over 30lbs. 35ish is when it enters into the inefficient range which can lead to through the roof egts and compressor wheels coming apart. I wouldnt pass 30lbs. Thats my .02 anyway.
