What type of hp do you think I can generate on an 82 n/a 900 8v 5spd by installing a hot cam, upgraded valve springs, port matched mss header, and a free flow exhaust with 'test pipe'? I know turbo is the ideal for many but I like the idea of jazzing up my na to have a sportier setup with an upgraded suspension. Think 140hp is achievable? (albeit without the torque of the turbo cars). thanks!
