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.
