I have a question about building a ls/vtec but boring the block to 84mm. So basically like the crv/vtec. My question is it okay to run the crv/vtec (B20/B16) pistons that wiseco and Je make. It would be low compression and it would have some huge turbo cams. I know that its known that the valve reliefs for the b16 and b18a/b are different so this is why i ask. BTW: The block will be sleeved by darton. Thanks in advance!
