I can answer the pully one. If you get an underdrive pully, it will only be 25%. The 99+'s are 42% which is better, but kinda sucks for our years. Better than nothing, but I dont think I even felt a change in my car after the install...

25% of what?

eibach springs imo
pulleys are nice but not more than a few horses so your not gonna feel it
get some 373 gears along with a detroit truetrac
and save your money on the throttle body it will do absolutely nothing for you, get some tail lights instead

thanx, so far i know how to save about $350-$450 on something that i won't need

Underdrive pullies have a smaller diameter than stock pullies. 25% means it's 25% smaller than stock...

well as far as i undersdand the smaller the underdrive pulley is the more powerfull the engine is going to run, but will require higher RPM to get the same speed

No, it's just spinning the belt driven accessories slower - not the actual motor.

Vovovovan

so what how is that better if the belt spins slower?

it's like being in a lower gear on a bicycle, i think, so it takes less power to spin the smaller pulley. not a mod i'm going to get though.
