N54 Single Turbo kit 135i 335i/xi 535i/xi

N54 top mount single turbo kit. Multiple chassis fitments. We use a pulsar turbo and a pulsar wastegate to control boost. Prioritizing the wastegate is essential when building a car that will be easily tunable and deliver consistent repeatable results without over boosting and causing potential for damage. 700whp+ proven with room for more power. Heat sinked 02 bungs are used to provide longevity for the 02 sensor even when running 30+ psi of boost. Included in the kit is turbo manifold, downpipe, water pipe, wastegate dump tube, full 10an oil drain line, 6an water lines, 2.5in silicone coupler and hot side charge pipe, 4an oil feed line. All stainless steel is back purged to ensure longevity of the item and avoid "sugaring" which can cause potential damage to components. All hot parts have a limited lifetime warranty
