I was looking into mods and stuff. And i seen where i can put a bigger pulley on and a water pump under drive pulley. I also seen somthing about hubs. Would both these pulleys require hubs? Not to sure on this stuff. Thanks

OK first off you get smaller sc pulleys to make note boost to male more power. But you can't just drop pulley sizes without doing supporting mods or you will grenade the engine. There is a awesome thread here search general mod plan. A lot of good reading on how to mod.

 

Yes turbo i kno i would have to get a diff throttle body, plugs, tstat etc..but my question is if i order the pulleys do i need to get their "own" hub for both of them or wht? Im a lil confused

 

you can either buy press on pulleys or buy the modular pulley hub with modular pulleys for the sc. the water pump under drive pulley bolts to the water pump. i would either let the water pump pulley alone or buy a electric water pump if it were me. the alternator pulley is press on as well but for the minimal gains i wouldnt bother with it either.
