whats best lightweight crank/alt pully to throw on my eco to help rev faster/have less rotating mass without killing my battery as I have an aftermarket system? I read a post a while back about a group purchase or something of someone who made both lightweight but not underdriven as underdriven will give me a loss of power with such a stereo, this is my daily driver so I need functionality. this post is for opinions btw, so opinionate! and if you have pics/vids of yours installed show em!
btw my eco has rksport spring inserts, upper and lower ttr mounts, wai, 2.5" full exhaust going through a magnaflow cat and flowmaster super 40 muffler, big 3.
MD-LD9 is who you are looking for.
This is his profile. Send him a message and ask him when he is going to run his next GP.

anyone make lightweight alt pully for 2200?
the alt pulleys are the same for the 2200 and 2.4, and I believe the eco as well.
So MD-LD9's, or I think AEM makes one??
My alternator pulleys fit every motor that was native in a cavalier from 95-05.

what are the advantages and disadvantages of a alt&crank pulley anyways?
do they make one for my 96 2.2 sunfire?

the advantages and disadvantages were discussed in several threads. synopsis i read is:
adv-less weight in the pulley helps the motor perform
dis-cost of replacing the stock pulley, time it takes to replace stock pulley (tho it's not long, it's still a measure of time that is gone)
the 96 sunfire prob has an LN2/2.2 OHV. so yes. look at md-ld9's sig. sunfires and cavaliers have the same engines respectively. so parts for a particular cavalier will be the same for a particular sunfire (motor wise). you can't really label a car and year as some cars in a year have 2-3 different engines. you'd want to look at what engine you have, not the car model. all alternator pulley's are the same.
