Sorry T-Typed, the 86 87 turbo was mounted on the front of the motor for the intercooled set up. The down pipe will not fit, due to the reason not only because the turbo is on the front, but that the turbo is actually "clocked" or twisted differently into the intake. If you are in search of an aftermarket DP on the larger side, ATR i believe sells an entire kit for the Hot Air cars, and they are a little on the pricey side.
Other than that, MEASE performance in NJ might have a few pipes left which mount directly to the turbo, eliminating that elbow on your turbo. They are a tight fit, but they are 3" and look real nice. Lee Thompson used to have a few of his own 3" pipes, but last time I talked with him, he said he was all out....With Lee's pipe, you needed to buy an external gate, because his eliminated the puck inside the elbow (eliminated the elbow completely), and the Mease pipe has the puck integrated like the stock elbow.
Other thank that, it is a little difficult to find a manufacturer of our DP's because it is a lot of bending and very limited space. Good luck with whatever you decide!
