Hate to burst your bubble, but better deals are out there. I bought all the peices for my NA-T conversion for a hair over 500, that includes the turbo, manifold, coil pack, injectors, and, everything else
Coil packs go on here for 30-40 bucks, and turbo injectors for another 40 or so.
Look for someone who is parting out a turbo supra, and purchase all the parts at once from them, and get a great deal.
