The fabrication of the turbo system was a large challenge in packaging. With OEM power steering, A/C and cutting of the car kept at a minimum. Only 2 large holes were cut in the car. That was where the tubes leave the inter coolers and run through the inner edge of the fenders and through the core support. The air leaves the turbos and exits down toward the ground and through the inlets to the intercoolers. All of that was not so bad. The exhaust and waste gate plumbing was the real issue.

Building the driver side exhaust was a challenge. Found some very tight stainless U-bends on ebay that worked great.

The waste gate and turbo outlet section pre and post jethot coated. Used their ultra high temp so I did not have to worry about "burning off" the standard coating while dialing in the tune. Also was trying to keep as much heat in the exhaust instead of cooking the fiberglass hood.

In this picture it shows how little room there is with the fans in. The waste gates actually fit into the shroud in spots.

Very nice build, look forward to seeing this finished! If you don't mind my saying so, the old radiator looks a little out of place now : )) Good luck!

Here is a pic with the done engine compartment. Yes, the stock radiator is not as flashy as the rest but I have had issues with aluminum ones in the past and this one works great.

Here is the inside with the sound deadener installed. Raised the rear of the tunnel a little so it can sit a little lower and not have any issues hitting the yoke or driveshaft

Here is a view of one inner fender. Above the intercoolers there is a air pump (smog) from a modern can re-purposed as crank case vac's. One each side connected to each valve cover. I have the PCM control them through a pulse width module. From 500rpm to 2000rpm they run at 30%. From there they ramp up to 100% by 3500rpm.

Side view. I went with a satin finish where flat/semi gloss would normally be (hood,stripes,spoiler,tail panel) for a more modern touch.
