Product Description

351 Swap Turbo Kit
The On 3 Performance Turbo Kit for 1986-1993 Fox Mustang with 5.8L swap features a single 70mm Turbo with intercooler. This kit is capable of 400 to 800 horsepower(with proper supporting modifications)! Headers and crossover tubing are high temp black coated mild steel, while the rest is 304 stainless steel. Boost is controlled by a 44mm Wastegate and pressure relief is handled by a 50mm Blow-off Valve. All needed hoses, lines, couplers, clamps, brackets, and hardware are included.

Installation Note
-The y-pipe to connect the downpipe to the catback is not included.
-Air filter not included.

Modification Required
While this kit is designed to be a bolt on, it is not a direct fit. The alternator will need to be relocated with the included bracket. Some modifications will be required! Such as cutting and clearancing to fit the intercooler and tubing, minor dimpling of the tubing to clear chassis components, tapping an oil return in the oil pan, etc. You will need to upgrade your fuel system; a high flow fuel pump and injectors will be required along with a properly calibrated MAF. Custom tuning will be required! 1986-1988 Mustang will require a Mass Air Conversion. All 86-93 5.8s will require an oil Filter Relocation Kit!

What is a Turbocharger?
A Turbocharger, or Turbo, is powered by your engines exhaust flow. Exhaust from the engine spins the Turbine which is connected to the compressor. The compressor draws in filtered ambient air, compresses it and feeds it to the engine. The amount of pressure above atmospheric pressure is referred to as boost. Turbo systems are generally referred to as being very efficient power producers and offer stock like driveability with significant power increase potential.

-Fits 1986-93 Mustang w/ 351 swap.
