wow... good post, I'm impressed.
as for swaps, the ls1 is pretty much the hot swap into any kinda car you can think of. so there are even aftermarket harnesses and stuff to make it cleaner. check out painless wiring.com.
this swap will end up being really eazy and I'm sure xat will be able to handle it. also the ls2 is being put in most everything now, all the part interchange, its just a few more cubes and better flowing heads. makes 400hp stock instead of 300ish for the ls1. so its going to be even easier to get ahold of motors soon.
rep for you mike.
I drove a stock sr swap for the first time, a few weeks ago and got out wondering what all the hype way about. it was pretty weak, even compaired to a good running ka. I'm sure a big turbo and 25lbs would help but why... when it would be cheaper in the long run to just put a v8 in it... and for drifting, turbo lag has to suck ass.
mike, hope you get that thing to FD and kick bills ass with it

show him how something with some hp slides
