GT3076R Turbo assembly with internal wastegate (Not Kit). Garrett GT3076R turbo with ATP proprietary exhaust housing and internal wastegate all ready to bolt up to Mazdaspeed6 exhaust manifold. Includes all coolant and oil connections to connect turbo to factory lines. Turbo as assembled has industry standard 3" V-Band outlet. Turbo is efficient up to 26 psi on the MS6 2.3L turbo engine and can produce over 500 crank HP as configured with the supporting mods and proper tuning. Does not include 3" inlet pipe and 3" downpipe necessary to complete a "kit" and is recommended for shop use only. Turbo spools about 400-500 rpms later than the GT3071R on the 2.3L MS6 engine and should only be used on this engine if you plan to exceed 450 crank HP (or go over 22 psi of boost).
