talk to mattback and rainforest. chris built a mini-me in the spring that came out pretty well, but they didn't have many good things to say about it. as i understand...they both said it was difficult to wire and overall not an easy swap or worth the time.
if you're looking at a sohc vtec...turbo setup, then i'd look at a zc. they're low compression, come with around 135hp and go pretty well without turbo...plus they're not that expensive.
