I have heard that in order to properly put CTR pistons into a B16 you have to modify the CTR piston slightly ( I think i heard it is around the wristpin, and on the dome for proper cam valvetrain clearance ). If this true can someone tell me the proper modifications needed to make the pistons fit properly without malfunction

thanks guys

 

you need to shave 1mm off each side of the rod or piston by the wristpin area

 

You need to have a shop do it.

 

alright thanks for the help guys
