Anybody out there ever done a B18C block w/B16A head conversion with integra or Civic Type R pistons? If so than what was the compression and how much HP did you get?

Ive seen a b16 block with a GSR head... but not the other way around... I think he said that it raised his compression to almost 11:1

fowler!

Well, if you put the b16a head on the GSR without switching pistons, you'll actually lower your compression ratio due to the shape of the head's combustion chamber.

Likewise if you put a GSR head on a b16a, you'll raise the compression about .2 pts. I believe.

Basically known as the Poorman's type R motor. If you plan on putting a stock b16a head on a GSR, I wouldn't do it. For about that much you could get a Skunk2 manifold and some other goodies. Now if you're doing an ITR head, that's a different story. Very worth it. Just switch to some CTR or JDM P30 pistons and you'll be good to go

the b16a head is the same as the type r head except for some factory porting. You can actually make the B16a head better.
