Our Gen 1 b58 turbo kit features a 6-1 manifold with 1.25in runners. This design is utilized for quick throttle response, and coupled with either a garrett g40-1150 or 6870 precision turbo and supporting mods capable of making well over 1000hp. Our down pipe is 3.5in and fits with the factory exhaust. Out kit uses a single tial 44mm wastegate. Featured in the test car is a vanjen clamp, this is an option but not supplied with our regular kit. Email if you’d like to add this option.
