I've been looking around for an aftermarket pulley and its between either a ZPI or an NTS, lightweight or underdrive pulley n i jus cant decide what kind. I want something that I can install n not have to worry about damaging my engine down the road. Please send me some thoughts n reviews, pro's n con's, anything helpful will be taken into consideration.

Also does anyone know if you can get more HP out of a full pulley set (waterpump,alternator...) or if they are only usefull for more power output for a stereo system?

 

well NST hands down... plus they're still in business... ZPI is now Turbotoyota's... lol

 

i have the HOB from fastscions.com and it's great as well as NST overdrive alternator and water pump pulleys and the car drives and feels great. so i'd have to say get all 3 pulleys and it's your choice on the HOB or NST for the crank, your better off getting the pulleys new because you don't know if the previous owner could of messed them up or installed them wrong on his/her car.
