Don't mean to be abrasive but facts are facts.

What is wrong with SRP ? just curious.
The SRP pistons are made out of a 4032 alloy that is not as strong as a 2618 uded in a tradtional JE, I woulf not reccomend more then a 200Hp shot on a SRP. We do have some nitrous specific pistons what combo are you running?
And this is from the man who sells them. If you're close to the ragged edge in RPM and close to lean for the best performance they are too brittle. I've had one failure with them and 2 failures with Wisco pistons. All on Alcohol. I want use a Mahle piston either.
