More Turbo Pipe

I finished most of the hot side turbo pipe tonight. I had to make some changes to it from the last post and I also modified the motor mounts.

For the mounts, I re-drilled the 1/2″ bushing holes 7/8″ lower. This will allow the hood to close with the Speedmasters intake that I have. But I will have to buy a F-Body oil pump instead of cutting and welding the truck pan. The main reason is that the F-Body pan is 1″ shorter in the front and allows better steering rack clearance. I will post a final mount drawing when I pull the motor for assembly and re-cut the plates for the hole changes.

On the turbo side I moved the exhaust plate lower and towards the center more. This placement seems to give good clearance for the belts and water pump outlets. I also started on the 3″ down pipe and I think I have a good placement for the wastegate. Once everything is tacked in place I will cut where needed to allow for V-band clamps and do the final welding.

Turbo Hot Side Begins

I started plumbing the hot side of the turbo system tonight. Cut the truck manifolds so they would exit straight forward and tacked on 2.5″ tubing. I didn’t feel like waiting for mandrel bend sections, so everything will be pie cut pieces.

I also tested the hood closure and found out that I need to modify the main rack/motor plates to drop the rack and motor about 3/4″ so the hood will clear the throttle body. This will also drop the turbo lower, so I plumbed it a little higher.
