This involves a ball bearing vs normal. Like Kalani said, you should get a Garrett Turbo for your 1.8 setup. Alright well if you wanted ball bearing you would have to goto the GT Ballistics Series, is it worth it to pay 1900 dollars for a turbo in that series? What kind of power would a Big T28 Ball Bearing Make? Also, at what RPM would you acheive spool up? Kalani, Shawn, help please. Thanks
