I honestly wouldn't go that route as everything you've stated. For starters, parts are harder& cost more, added weight & most important auto or 5spd. Personally, why don't you go with a B16 or B18C1. Not sure what money you're working with. Also why would you really want to have someone banging on your car to get something to work that wasn't designed to fit your ride. I have a B16 in my EF Si & love it. Don't get me wrong the H22A is like having air cooled Bug & putting a 2.0 in the bug it'll fly.Choice is yours, good luck
