Default Twin Turbo LT1

This is a complete twin turbo set up for a C4 corvette that will make 1200hp easily. There was over $25k spent on this setup and everything is BRAND NEW. The headers and downpipes fit the chassis but the AC has to be removed and the accessories will need relocated. Everything clears the hood and fits nicely within the chassis. The headers are jet hot coated and are stepped from 1 3/4 to 1 7/8. They are made from 304 stainless and were tig welded all custom fitted and crafted no chinese junk here.

Turbos are Precision GT 6152 with the new boosted turbine wheels. The wastegates are Tail 38mm.

Motor 383ci:
-LT1 block .030 over splayed billet main caps.
-DRM road race oil pan
-Callies 3.75" stroke crank
-Billet 5.85 Oliver rods
-J&E 8.5:1 turbo pistons (I also have a set of new Diamond flat tops ~ 12.5:1CR weight matched for this setup)
-Billet solid roller turbo cam (Also have a NOS grind cam)
-Cloyes Billet roller timing chain
-ATI balancer
-AFR 227 CNC ported heads
-Jesel rocker shaft rockers
-Custom sheet metal valve covers that will clear a C4 LT1 accessories
-LT4 intake modified for distributor
-FAST engine management with WBO2 I also have the adapter harness to piggy back the factory ECU in a C4
-MSD pro billet distributor with MSD 8.5mm wires
-DRM twin 58mm throttle body

I am open to offers and may separate the package. This stuff is all top notch and no junk. Motor was run to break in but normally aspirated and never run hard. I has 300 miles on it. I put a stock motor back in the car and sold the car now the motor has to go.
There are four pages of pictures and a few with the parts mocked up on a C4.

I will sell the entire package for $10,500 and would be willing to take vehicle trades not looking for projects or parts. Again no junk no excuses everything is brand new.
