ATR Headers/Intake Manifold/Intercooler and more

[Kevin87TurboT]

Up for sale is a set of ATR headers for 86-87 GN. They include the crossover pipe and mounting hardware. These are the best that you can find for a 10 second GN or faster. I'll take $550 shipped in the 48 States.
I have an intake for sale, including plenum, TB and fuel rails. One of the corners had a small crack that was professionally repaired. It works great. $350 shipped in the 48 States.
I also have a stock intercooler for $110 shipped.
Extra set of stock IC brackets. $50 shipped.

Id like to be put 1st in line for the ATR headers.

What kind of wastegate does it require?

What kind of downpipe will work with these headers?
