Will a d15b7 fit into a 88 crx hf direct fit or will things need to be changed and custom made?

 

Ahh, easy. My buddy did the same swap a few years back with a turbo d15.
It dosen't require a mount change or anything. It does, of course, require a new ECU, wire harness, and, as with any swap, beer.....lots of beer. Hasport makes a good set of solid mounts that'l make things a bit easier.
