Use a 4.8/5.3L Iron Block, not the LS1/6 Block. Get some dished pistons, flat top may be too much CR depending on the heads. Ditch the FAST intake and use an LS6. Definitely get with aftermarket heads, TFS, AFR, PRC, Mast etc. Turbos a WAYYYYY too big, Outlaw Drag Radial Guys use either 76mm or 88mm Turbos and the go 6's. I would do a 4L80e for a street car as opposed to a T56. Also, 4.10s will be too much gear. No need for Turbo headers either, truck manifolds will work fine. Fuel Rails are a definite, you will also a higher LPH rater pump(s) and an adjustable FRP. No need for an MSD ignition, use stock coils.
