Performance You Can Feel. Reliability You Can Trust.
The Stealth Mach 1 64 Turbo is the perfect upgrade for L5P and L5D owners looking for more power without compromising reliability.

This turbo uses a customized nozzle ring and/or shroud plate.  It’s been engineered to provide amazing response and performance. 

This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost which may shorten the life of the turbo or engine and may void the turbo warranty.
