Upper plenum / spacer question.

[scot w.]

What spacer do i need in order to clear the 4" Inlet pipe to my new PTE-70 GTQ? Here is a view of the turbo / TB, you can see how the TB needs to go up about 1/2" and it even has the phenolic spacer in these pics.

Call Champion or DLS. They have a thick plenum spacer thats 1.5in.thick. You can mill it down if need be. My throttle body sits really high now and hits the hood insulation.
