The Most Power Producing Turbo Upgrade On The Market

A Bolt-On Upgrade That Flies Under The Radar

We re-contour the OEM turbine and compressor housings to fit the larger turbo so to the untrained eye, they look factory stock. We even retain the factory heat shielding for safety and to keep this turbo upgrade under the radar.
