Best Compression ratio pistons for SR20 rebuild

[Doofer]

I'm rebuilding my Sr20 engine in the next few weeks and Im not sure which ratio pistons to buy.. It'l have a HKS GTRS turbo if that makes any difference? Also what size gasket should be used? It will be standard size bore, ACL bearings and A.R.P bolts top and bottom.. Blacktop non vvt. Anyone have advice for me?

it'd be kinda pointless to go putting new pistons into old bores, i'd be getting it overbored if i were you

What the Wang said, for the love of god bore it!

Is on of the bores surely not damaged anyway sure didn't a ring landing shit itself or something?

They were just about to go John. I seen the hair line cracks when I took out the first piston. I literally pressed it with my finger nail and the side of the piston fell apart in me hand.. Insanely lucky not to break before that and destroy the bore.. 5 minutes with a honer and it would be brand new again.. How much of an advantage is there of goin over sized. What extra horse power or torque would be gained by an extra mil or two over sized? Genuine question I'm not bein smart

definetly want a bore , or at very least checked , your engine over 15 years old at very least every engine has wear , i definetly wouldnt order anything till bore is measure properly

And if I was to bore it how much bigger should I go to keep it safe
