i have an '82 zxt (just rebuilt the engine,new turbo,injectors) that has the p90a head on it.....
w/an adjustable pop-off valve (6-12 lbs) will just adjusting it give me (some) more boost?...i'm kinda concerned about that p90a head also...i believe its hydraulic and heard its not a good one to boost (very much) with......what do you think?
thanks......s
