Hey Chris.
Great project Chris! I am in the middle of a similar project -- though I am going for s14 power and a m3 CR gearbox. I'd love to come take a look at your car sometime, especially to see your radiator support modifications...I am planning something similar.
I'm in Portland, not far from PIR raceway, actually...
Drop me a note sometime, if you'd like.
Cheers,
Dominic
