B18b w/ b16 pistons Q??
 

I have a 94 integra with a B18b and did a compression test. From the looks of it the rings are going, Low comp. Question is I have a brand new set of b16 PR3 piston and wanted to know if I put them in my B18b could I run it with stock engine management and fuel management?

compression will be MUCH worse, considering the b16 have a smaller bore size :P

Re: B18b w/ b16 pistons Q??
 

Aint they both 81mm? And will I be Able to run stock management with that setup? Motor has no mods just needs new pistons and rings and have PR3's laying around.

oops, you're right :-[

ull probably be ok without management and if u ping just retard the dizzy a bit

if your rings are shot its best to start with a fresh slate by getting overbore pistons and doing the required machine work to the block

your going to need to run 91+ but it should be fine with out any other mods. keep im mind theres no knock sensor so if you dont get 91+ your computer wont save you.

honestly a re-ring of your old pistons would prolly be fine unless you want more compression (this is a turbo site) however if the motors at the point it needs rings then theres proly more wrong than that... maybe seals and gaskets

How about Pr3's and a thicker head gasket. By any chance does anyone know if they will give me more hp and how much,Just wondering?
