Hi everyone,
I know some of you out there know some about this so I thought I'd ask
clarification on a few questions I have. I have an L20b sitting in the
garage right now striped down to the block. I'm doing a total rebuild.
Right now I'm debating weather I should bore it out 2mm and put a z22s
crank, rods, and pistons in or leave it as is. My calculations seem to
bring the compression ratio pretty high though with the first option (around
9.5-9.8:1). I have a u67 casting head that I'm putting on. Does anyone
know if this is right? This is going to be a street driver. Also does
anyone know where I could get a crank from a z22? Every parts store I've
tried can't get one and I don't really want to have to tromp through junk
yards to try and find one. I may have to wait till it warms up to get one.
Thanks
