Is it possible to make up the lost power between a dx and an si with bolt ons. I'm wondering how much power the basics would add to the dx motor and if it would even be comparable to a bone stock si. I know the si gearbox would be helpful and I know most all the stuff put on the dx motor will work on the si engine but this is a project I'm gonna start with my little brother and I rather not let him spend money on stuff that will make more noise then noticable power. If possible can any dx hatch owners post their stock times and modded times and their experiences with performance parts.
