Got a nice big intercooler! It is used however helped make 1200 Wheel HP on a Twin Turbo V8 in a GN, custom made by Ken Duttweiler and cost $1100 new. Snagged it for really low $ so I will re-plumb the boosted air to this big sucker in front of my radiator.




Also got my 4L80E custom torque converter from Hughes, it was $900 but it was custom built and will handle 1000 HP without an issue and has electronic lockup for highway cruising with 100% lockup. I also have the electronic shifting kit which was custom built so I can run either a mouse to shift the gears or push buttons on the steering wheel. manual shift only no auto shift but the column shift still selects Park N, and Drive. A LED shows gears 1 through 4.

$300 custom controller for the push button shifted 4 speed 4L80E trans built for 1200 HP:


Quote from the seller: "I saw that you weren't running an intercooler in your twin project, and I have this kicking around the garage. A friend of mine ran a GN in twin turbo form on the street in Brooklyn for a few years before it became a full on tube chassis car, and this was the intercooler Ken Duttweiler built for him. The car ran pretty hard (9 second quarter mile) but I don't know much about the flow rate or anything like that. The inlets are 2.5 inch pipe, and there is one 2.5 inch outlet at the bottom."



I should take a picture of the SFI rated ATI balancer and the TA SFI flexplate... Next move is POR the underside of the car then add re-chromed rear bumper, add the tubular adjustable rear suspension and rear disk brakes. Then drive shaft loop, install the engine and fire it up, complete the interior etc.

pushed the car out of the garage to coat the floor with epoxy and decided to snap a few pics:
