1999 Powerstroke KC38R 66mm/73mm Turbocharger (300451)

Fits

Supports: Up to 238cc/80% injectors

The KC Turbos 300451 KC38R 66mm/73mm Turbocharger is a perfect example of how modern turbo technology can completely transform a 20-year-old turbo design.

Generally, most people end up focusing too much on the "compressor wheel" since that is what we can typically see. However 90% of the "turbo magic" comes from the turbine side of the turbo, which is where KC Turbos has done their due diligence to make this the best option on the market. No other drop-in 7.3L turbo on the market runs a larger shaft. They have increased the thickness of the shaft from 6.4mm to a whopping 7.5mm in order to support the extra power, which helps make KC Turbos even more robust. Modelled after the 366SXE compressor wheel, the KC Turbos Compressor Wheel has the same profile, shape, and blade style, however, it utilizes a Larger 7x7 wheel and is reverse rotation. This wheel is not only bigger but much stronger!

• EXHAUST BRAKES: Do exhaust brakes work with KC turbos? KC Turbos has found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues.  These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aid in braking.  This can be hard on a turbo and motor and is not recommended.  It will be up to the customer to verify fitment and functionality.
• KC turbos are designed to fit directly in 7.3 equipped pick-up trucks. Although KC turbos can drop into 7.3 equipped Vans, you will need to modify the turbo intake boot and down-pipe for proper fitment.
