hey guys kind new here and did some searching but couldn't find what i was looking for. I have a 91 si and and a buddy of mine is in the process of turboing his DOHC ZC and giving me the stock pistons and rods. My questioni s how much abuse can the factory ZC pistons handle?? I know that they'll upo the compression but i'm thinking of running about a 50 or 75 shot. I just want to make sure they will take it. And would it be worth it tot get some after market rods to ensure the strength of no? Thanks guys.

 

You are going to need management of some sort if you want to make power and be reliable...ZC (p29 or PM7) pistons aren't any stronger than what you have now, and you are more likely to experience detonation at the higher compression level, which will be especially critical with nitrous...I'd run the 75 shot on the stock A6, and be sure to run a wet kit.
