Slowboy Racing GT Turbo Kit

The Slowboy Racing turbo kit has several features we like, including the cast manifold and O2 housings, user-selectable wastegate routing, and elegant design.

The cast manifold and O2 housing are made of cast stainless steel, which resists rusting, warping and cracking. The O2 housing has a built-in flange for the included Tial 38mm external wastegate. The clever design of the housing means you can run the wastegate back in to the downpipe, or vent it to atmosphere (for race/offroad use only, of course!).

Select from a GT30R or GT35R turbo. Both are T3/T4 hybrid water-cooled turbos, with 4" shrouded anti-surge compressor housings. By default we specify the .63 A/R ratio for the turbine section, but other ratios are available by special request.

For the intake piping, you can choose between a stock-MAF setup, or a MAF-less pipe (as shown above) for cars running an ECU+/MAF Translator/AEM that aren't using the stock MAF.

Kit comes with everything pictured, including manifold, turbo, O2 housing, piping, and hardware. Choose external or internal wastegate routing when you order, and the appropriate wastegate outlet pipe will be included in your kit.
