GT35R bolt on turbo kit for Mazdaspeed6. Garrett GT3582R turbo with ATP proprietary exhaust housing and internal wastegate all ready to bolt up to Mazdaspeed3 exhaust manifold and downpipe. Includes all coolant and oil connections to connect turbo to factory lines. Turbo is efficient up to over 30 psi on the MS3 2.3L turbo engine and can produce between 550 and 600 crank HP on a highly modified engine if you dare to run that much boost. The GT35R is a great spooling turbo capable of this level of HP and there is no substitute for it's power and response. Spools about 700 to 800 RPM's later than the GT3071R on the same 2.3L engine.

This turbo has a 4" inlet, so be sure you have an intake or turbo inlet pipe capable of connecting to this size inlet.
