low compression pistons

alright is their low compression pistons out there for a geo prizm 7afe engine and if not what would i have to do to safely run more then 5 psi boost and a 75 shot of nitrous without completly killing my engine?? probally should of thought of this before installing the turbo but anyways any help would be greatly appriciated also my budget is about $500
Thanks!

sorry to disapoint u i kno a guy that had the same setup an it lasted 1 drag season before it threw a rod. only differenc is he had a 4age20 v with is stronger than your engien. he put 8.5.1 comp pistons in it. he said he think the nitrous killed it

so the nitrous is probally a no go then alrighty then i'll go back to the drawing board i guess
