In Reply to: same question...which mod is better?? posted by J///M3 on January 09, 2000 at 19:28:18:
: 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?)
Maybe, I'd rather go for the light flywheel
: 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.
