I don't think that people understood what i was trying to say in my last post.
anyway. it goes like this. if I put GSR pistons in a B16 it would actually yield a lower CR because they are flat-top pistons. what I'm trying to get at is I can't seem to find 9:1 pistons in any reputable piston company for a B16. if I put 9.8 GSR pistons in a B16 block, B16 head would I lower the CR. would that get me close enough to 9:1. I know alot of people do pistons in B16's, let me know whats goin on. I don't wanna raise the compression instead of lowering it.

 

9.8:1CR pistons for a B18C1 will yield 8.65:1CR in a B16A.

I know SRP makes 9:1CR pistons for B16As. http://www.crower.com/cat/import/hon...rp.shtml#b16a1 I'm sure there are others out there.
