Swaps are a pain in the ass for these cars honestly... Is his car carburetted or EFI???
It's alot easier if it's EFI... he can swap a B series engine in there (just liek a civic on integra)
www.placeracing.com makes a kit for these cars that allow you to do it.
If his car is carburetted. It's more trouble but it can be done (Hell I converted my carburetted Accord to EFI)
