Description:
Because of the popularity of the KC38r turbo for the 7.3, We have made a smaller version of the turbo for those running average size injectors. Also known as the Tiger turbo. The 63mm compressor wheel is drastically different, It is a larger, 7x7 wheel and is modeled after the 366sxe compressor wheel. It Has the same profile, shape, and blade style, except it is reverse rotation. This wheel is not only bigger, but stronger. It has thicker blades, thicker hub, and thicker backing, this makes it much less prone to fatigue and wheel burst. The turbine wheel is also much larger, 74mm vs the old 70mm and increased shaft thickness from a 6.4mm to a 7.5mm. The turbine wheel is much larger, 74mm vs the old 70mm and increased shaft thickness from a 6.4mm to a 7.5mm.
**EXHAUST BRAKES: We get asked a lot about exhaust brakes and if they work with our turbos. We have 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 aide 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.**
**If you have a plastic CCV or CCV mod PLEASE EMAIL YOUR ORDER # WITH THE TYPE OF CCV YOU HAVE. This will affect the type of boot sent with the turbo.**
