There is such a wide range of hp regarding what else you have done to your car if you go na, and if your f-i, then the turbo setup and psi determine your hp. People have gotten over 500 whp with a good turbo setup and built block, and Ive heard of gsr's getting up to 240 or more whp. The ls-vtec setup would I think have a little more torque than the gsr motor. For the people here to better answer your question, tell us how much money you are dealing with and how far you would go with either setup.
