Like jr-ss said ! Stock det pistons will work but p11 cams only nothing bigger !
I just pulled my brother sr out of is s14 ! Stock bottom end that was refresh with built head , precision 4828 and suporting mod
(Never ran after the rebuilt) Did about 6 pull on the dyno tuning the car (at around 10psi) it started to do blowby like mother fucker
We Did a leak down test and 90% leak on 1 and 4 ... 2 and 3 : 0% leak
Took everything appart to find out the ring land on 1 and 4 is cracked (stock pistons have there limit i guess or its just bad luck)
Lucky us , no damage to the cylinder walls
