sup guys i have a 87 7mgte that i did a rebuild on i was gonna get je pistons but 4 right know ima go stock..
Now ima runnin sum pretty good stuff under my hood walbro fuel pump 550 injectors spearco intercooler down pipe 3inch and appexi exhaust u think the pistons can hold up to 18 psi? i plan on boosting 12 after i break it in than bigger.

hmmm.... it's hard to say really... i guess as long as your fuel is happy then i guess they might
but after a while they may commit suicide.... so i would suggest... go stock for now.. save for je's prolly 20' over.... so if your stockies do commit suicide and score the bore you can just rebore and slip in the new ones :)
