There are some online salvage companies that can help you out, but I don't remember the addresses offhand.

You're going to have a hellofa time fitting an H22A in there. The entire engine bay is going to need rewiring and it's going to take a LOT of 100% custom parts. Not to mention probably some banging and cutting.

Unless you have a lot of free cash sitting around that you don't mind saying "goodbye" to forever, you should probably keep that car stock as a daily beater. Don't get me wrong, I like the older 'ludes, but it is just too cost-preventive to build one up.
