MR2 engines are roumored to be able to fit in a paseo...that would help some....then probly an intake, header, and exhaust....i'm in the same boat right now with mine.....headlights are expensive (like $80 a piece) you are almos better off puting an HID kit in....you should be able to get the lights on autopartswarehouse.com or just type a search in google
hope this helps
