I had a GSR stroked and my honest opinion on it is this....Yes it made good torque but it didnt hold together worth shit. If ur doing to to rev out then be careful. It didnt like the revs at all and mine was turbod. At 11psi mine made 317whp and 276trq. SO yes it makes hellacious torque but what good is it if it didnt last but 2000 miles. I wouldnt do it for a DD at all. It is cool to tell people you have it but functionality is extremely important to me in a car.
