ok guys i plan on purchasing a 90-91 mx6 turbo soon,and i would like to know what is the mamimum hp that i can acheive on the stock motor without doing any internal engine work?

The GTs are 140 hp stock w/ 190 lbs of torque, with an upgraded turbo and some bolt ons, the possibilities are endless.

You actually can go pretty damn far on stock internals. These engines are built like a brick shithouse. Lots of people are making 200hp at the wheels without a problem (with sometimes as much as 280 ft-lbs of torque!), 250 seems pretty possible too, but it may be more.
