I did a b16 swap a little while ago and i want to just replace the pistons rings and bearings in the engine I'll be useing stock pistons and rods and stock rings and acl bearings. My question is can i just pull them out and replace the rings and bearings and than reinstall them in the motor with out sending the block to a machine shop and getting the bore honed to 81.5mm ?

 

as long as there isnt any scoring or any damage to the cylinder walls you should be fine. make sure your bearing clearances are good when you slap those acls in there

 

ok cool would OEM be better I have the tools to measure clearances ?

 

This is advise for making so so power.

 

I have new ACL bearings, standard size,lmk if your interested
