I have a d15b1 with all the d16a6 si stuff on it u could think of. I wanna turbo it now and was wondering just for the bottom end can I use crx racing H beam connecting rods on the stock crank and will d16 piston heads work with that? I got the top end rebuilt but do I need another head like the d16y8? I'm just starting with the block and it only has 80k miles on it. Just wanna run 10 psi. Please help.

 

Why not just turbo your b1/a6 combo?

Just start out with 6-7psi and see if that works for you while you build up something a little beefier
