I've got a 97' civic HX, that I want to put a new engine in. and this performance shop I talked to said they have b20 block from a crv and a gsr head. I was just wonder when the two are put together do they work well? Or is it more trouble than its worth?
I guess I am asking is it a good strong motor that will hold up?
