B20B and B20Z pistons OK for higher revs?
I am helping a guy swap his Civic Si's B16A2 block for a B20B/Z short block, and knowing the CRV rods will need to be replaced, we will probably use a set of forged Golden Eagles. My question is are the stock CRV pistons safe for higher revs (no higher than 8200)?

Pistons will be fine, the weak point in the system are the rod bolts... which you are replacing w/ the forged rods.

yea the rod bolts are the weak link but if your going to pull the block apart i highly recomend getting pistons and balancing the bottom end. it will end up being cheaper to do it right the first time.....(would also like to reconmend a clutch masteres flywheel which would def help it rev faster like the b16)

Re: B20B and B20Z pistons OK for higher revs? (dohcsideSi)
Im thinking about picking a b20z up next month and want to leave the internals stock for now. I do want to put ARP rod bolts in though. Only problem I have is that I don't really want to mess with tearing the whole motor apart since I don't plan on doing a rebuild on it right now. Would it be alright if I just pull the rods and pistons out, have the new bolts put into the rods, then put the rods and pistons back in with the same bearings, and torque the bolts back down to spec? Would it be bad on the bearings, and what about the piston rings?
