Wondering if anyone knows off hand of any complications associated with putting a 88-89 Integra head on a 90 Civic DX block? I will convert to MPFI, I had a DX block lying around and a very rudementary test fit concluded that it does at least fit on the block, turned the crank over (with timing belt installed) didn't hear any collisions, the 1.5 oil return hole is slightly smaller the the SI one but it appears if you use the SI head gasket there would be very minimal restriction with the oil draining from the head. Can anyone think of any compression problems?

 

never work...............G1 tegs are in a league of their own. they dont really interchange with many other cars except 84-87 CRX......

 

thanks, just looking for a little more power that that DPFI, but don't really want to go with a B swap, might just get a ZC. Just got bored and had the crap lying around the garage.
