Flowed turbine housings for low and high rpm boost control to match your engine for maximum air control. Waste gated and non waste gated housings are available to match your high horsepower engine.
In the 1989/90 5.9 6BTA Cummins a 18 cubic centimeter housing is a little to large and the turbo lag can be eliminated with a 16 cubic center housing.
The 91-93 engines have a 20 square center housing and turbo lag is quite obvious. By installing the non-waste gated 16 square centimeter housing, higher boost pressure and our larger injectors can pump the engine up to a 210 hp engine with 22 pounds of boost pressure.
