dose anyone off hand know the highest compression piston in an f/h series motor.
the jdm h22a has the some bore 87 mm as the h23a1, with a smaller stroke, I was under the interpertation the f series had a higher compression piston still in the 87mm range, all i have uncovered is there all 85 mm borebut the stroke varies.

Isnt there some kinda of frankinstine senario for utilizing the H23 crank, rods, some f22 pistons, and a h22 head? or evan a link.

any input would be apprechieted.
Thanks Cole

 

correct me if im wrong but do all H series mtrs. need to be sleeved. I know for a fact the JDM dose but I thought the USDM H23A1 diddent need to be sleeved.

need to be sleeved for high boost? low boost? N/A? stock?

please clarify the specific setup you are asking about.

 

some h22a blocks have fiber reinforced sleeves. therefore they need to be sleeved to use forged pistons.
