Every component in this kit is meticulously selected for premium, reliable performance, all while maintaining affordability.

The flanges are robust, measuring 1/2" thick, and equipped with slotted bolt holes. They are surfaced and straightened to guarantee an optimal sealing surface against the cylinder head. The kit is comprehensive, including (2) American-made 304SS Turbo Log Manifolds (available in 2.5" or 3" diameter), (2) American-made 304SS 90 Degree T4/T6 Turbo elbows with integrated wastegate tubes, and (2) Performance BorgWarner Turbochargers with various options available.
