I've heard 90-91 stock integra mounts fit nicely when swapping a B series engine in a 4th gen hatch. The only one that needs to be made custom is the passenger side mount.

Anybody else has any info on this?

 

That is correct accept think about this. 90-91 mounts are old and probably on their last leg if they arent already broken. I chose to go ahead and buy new mounts because of this and also because I trust the factory weld a whole lot more than I trust some JIM BOB cutting and welding the passenger side mount on my ride. I went with HCP they are good and affordable. But this is just my oppinion.
