Important Turbo Compatibility Notes:

BorgWarner SXE Turbos:

• S3XX turbos have larger compressor housings resulting in reduced hood clearance (~3mm).

• Variability in motor mount isolator thickness, age, and tolerances may make fitment tight.

• Turbine housing must have a 3" V-band outlet, NOT a Marmon flange.

• The V-band mating face should be aligned roughly with the rear surface of the T4 flange to avoid tubing misalignment or interference with valve covers.

Garrett Turbos:

• GTW and G-Series turbos have specific oil feed and drain fittings unique to each series and are not interchangeable.

• Note: Kits for GTX Gen2 turbos were discontinued in 2023 due to their unique oil drain requirements.

General Turbo Fitment:

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

• Compressor housing must have a 2" or 2.5" outlet.
