The entire dash bar behind the dash had to be swapped out.

There are too many little details that to be addressed to make it work right.

It's been a while since I've updated this thread.

Oil accumulators for turbo oil return


Modified AC lines for engine side


Heat reduction on white car engine bay


Modified AC lines on chassis side


Some of the powder coated parts


Rebuilt and re-coated calipers for both cars


Finished engine install on silver car.

Engine bay for the silver car. You'll notice the custom roll bar too.


Dyno graph from silver car. This same engine/turbo package was making 430whp in our race car on 110 leaded race fuel. This graph was on Arizona's crappy 91 octane fuel. 364whp is about all the 275mm Nitto NT05 street tires can handle.


Engine installed in white car. Major differences between this car and the silver car are smaller turbo GT2871 versus GT3076, single scroll versus twin scroll, and 5 speed versus 6 speed.


White car again


Trunk on the white car. The rear carpet section will install after the car is tuned. You can see the coolant expansion tank, intercooler, intercooler water pump and catch can.

The white car is ready to be tuned as of today so I should have horsepower figures some time next week. I'll get some videos too.

Both cars are going to be getting complete exterior reshoots, but right now, they are both multi-colored
