ive done some research on what pistons to put in my single cam. i was originally going to use the d16a1 pistons out of the old dohc motors in the old integras. they are basically the same pistons as those in the jdm dohc zc motor. but instead, i want to maybe go with b16 pistons. the usdm version (pr3) not jdm (p30). i have a y8 block and im going to use a z6 head so i dont have to go through changing to obd2. i noticed that the b16 pistons are a bit taller than sohc pistons. is there any rod combo with b16 pistons that would work?

thanks,
mike

 

no you cant; there is 6 mm bore difference. 75 vs. 81

 

pr3 and p30 has nothing to do with if it is a jdm engine or not, they are just different pistons for the jdm 1st gen and second gen.

 

Ive heard that if you sleeve the block you can bore to 81mm, but i just heard that not sure if you actually can

 

to get 812mm bore in a d16 you will need a custom crank.
79mm bore is the largest i ahve seen possible without the crank work.
