Well...lets see....so far, i've spent $102.00 on upgrades, and i can only guess....that i've gotten a gain of ~14 - 16HP more than stock......

And, i raced a bolt-on Integra(intake, exhaust) and pulled EVEN with it from 40 - 80, and those put out ~170 HP right...? So, i dont know if that means anything, but i think the mods might actually be working okay for me...But idunno....does that sound good?
