PureTurbo’s lightweight forged billet turbo wheel features a dramatically larger-than stock impeller (inlet side) and an increase in the turbine trim (exhaust side). This combination of high quality, lightweight components compensates for turbo lag despite being a functionally larger turbo. The cartridge supporting shaft is both larger and stronger, designed to handle the larger wheel and additional power paired with a custom SMSTune / TCU mod is nothing short of spectacular and not to mention the M177 is an incredible platform to build performance upon!
