In Reply to: same question...which mod is better?? posted by J///M3 on January 09, 2000 at 19:28:18:
significant gain is forced induction. sure, rear gears might give a little more acceleration, but i think you are a little more power hungry than that. i dont think that beyond what you already have, you will be able to feel a negligible difference. cams, which are expensive, might give enough difference to feel, but 20-30hp is about max. go forced and really feel a difference. i would say nitrous,, but who wants to have to refill a bottle all the time and take up space in the trunk. im scared of the juice anyway since my next door neighbor blew 2 engines in 2 cars already with nitrous.
: I know everyone has been asking this question lately, but what mods actually increase horsepower and acceleration?? I have the exhaust, ecis intake, short shifter. I also have eibach sways, rd springs, new pads and rotors on the car so now I want more speed goodies!! The mods in question are
: 1.throttle body(actually do anything?)
: 2.intake manifold(how big of a difference?)
: 3.underdrive pulleys(are they still a problem?)
: 4.cam shaft(what would be a good profile for street use?)
: I already plan on getting the sofware upgrade so this will be an added bonus on top of everything. Please give me your honest opinions on each modification.
