Kit Includes all coolant and oil connections to connect turbo to factory lines. Turbo is efficient 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.
Note, when upgrading turbochargers, supporting mods (fueling, etc) and proper tuning is always recommended. 3" intake pipe and 3" downpipe also available to maximize the turbos output.
