⚠️ Important Turbo Fitment Notes:

BorgWarner SXE Turbos:

• Turbine housing must have a 3" V-band outlet (not the standard Marmon flange).

• The v-band mating surface should align roughly with the rear plane of the T4 flange. Misalignment can cause tubing fitment issues.

Garrett Turbos:

• GTW and G-Series turbos have distinct oil feed and drain fittings — not interchangeable.

• As of 2023, kits for GTX Gen2 turbos are discontinued due to their unique oil drain needs.

General Turbo Requirements:

• Turbine housing must have a T4 inlet and 3" V-band outlet.

• Compressor housing outlet must be either 2" or 2.5".
