see this is exaclty what i needed to know! the srp pistons for my car, stock compression 9:5:1 are footnoted for use with nitrous. it doesnt mention anything about use with turbo, only the 8:5:1 comp. ones say for turbo use. thats what i was trying to firgure out. so i can still use the stock comp. ones for my turbo setup even though there is a footnote on their page for nitrous. i was thinking i wouldnt have a problem and if this is true then i'll buy em already!! drama drama

Re: Big ??? about building motor and tuning!

they are made out of the same materials regardless what thier footnote says, the only reason they recommend the lower c/r pistons for boost is because it would be safer, however 9.5:1 c/r srp forged pistons will still take a good 15 psi consistantly, the JE's are rated higher like consistant 20+ psi, but srp's should be fine.....
