If your gonna do an H22 swap, do it as an H2B swap with the B-series GSR or ITR tranny. It's supposed to be brutal.

As for your plans i would do the suspension and body work first. An engine is good and all, but it's nothing if you don;t have a good platform to put it on. I spent alot of time and money on getting my engine to run right and perfect, than i neglected to repair anything on the suspension and ended up spending close to a $1000 dollars in mods/repairs (seen my drop). Now that that is all sorted out, i can finally concentrate on the mini-me and a possible swap in the future. That's my .02 cents.
