I put a B16a2 and turbo in a 97 CX and it blew the valve seals. Is there an 18 series head that could be installed to give me a lower compression with the turbo and not degrade the performance much?

 

a b18b head would give lower compression, but thats a waste to even try

 

The only VTEC head is the one off a B18C1 (GS-R) and it has a smaller combustion chamber so that will raise compression. The B18C5 or Type R motor uses a modified (supposvely some porting) B16A head. I would recommend you either replace the seals or get another B16A head. If you want to lower compression, I would suggest new pistons. More expensive than anything else, but definately money well spent on a turbo application.

 

B16 head with stacked or thicker head gasket would be good.
