Did they need to pull your radiator to install the pulleys? and how much did people pay for install?:tiphat:

I was able to do the install myself with hand tools and a 4' pipe. You WILL need to remove the radiator fans and move the overflow tank, but not the radiator itself. With those items out of the way, I could release the tension on the belt with my 1/2 breaker bar + 3/8ths adapter (to fit in the tension socket). Then loosen the bolt from the top of the engine bay with a 19mm impact socket attached to the breaker bar, covered by the four foot pipe for leverage. I also had to lock the drive shaft against the frame with the OEM tire iron (this tip is posted somewhere on the forum). I was able to remove the pulley by wedging the breaker bar between the engine and pulley and wiggling it. It eventually slid off without too much force. A pulley puller might be a better choice. The NST pulley slid on with no effort.

I didn't install the overdrive alternator pulley, as it appeared that there was no way to remove the OEM pulley without an impact wrench. It spins freely and I was not willing to figure out a way to stop it from spinning, for fear of damaging the alternator itself.

I just had my pulley kit installed. I'm happy with the results. The engine revs a bit quicker and seems like it has a touch more power.

Hey guys. Just received my pulley kit today. I ordered black, but was sent blue. This is not a big deal. I ordered the CR-Lite pulleys, and just wanted to make sure that I received the correct pulleys and not the underdrive pulleys. Is there any way to tell? I am only worried b/c I received the wrong color, which could mean that I received the underdrive pulleys instead of the CR-Lite pulleys. Thanks.

I think you got the right one because the openings are different on the ud pulley. Why did you get an alternator pulley if you aren't going ud?

Look back a few posts and you'll see what I mean.

Thanks man. I got the alternator pulley b/c it is lightweight, even though it is not the underdrive one.

Interesting that they didnt brand their Lite set. you can always put it up to your current pulley and compare the sizing.

Yes, it is interesting that they didn't engrave their CR-Lite pulleys. It is the same design as the Unorthodox Racing one :stirthepot:. Don't have access to the car right now, or else I would have just put it up to my current pulleys and compare the size. Thanks man.

So i got mine a couple weeks ago and the build quality is very nice and clean.

A few words of advise when pulling the old one off.
  1. Take off the radiator fan - its only 3 bolts and 6 clips pull up and fish out the right side - no need to take off the radiator hose (makes for a lot of room to work)
  2. Use a good size breaker bar
  3. ***HUGE ONE HERE*** - Make sure on the manuals the car is in 6th gear
  4. When placing the tire iron in the differential be careful not to rest the iron against the aluminum shifter control arms
  5. When putting on the alternator pulley on take both bolts out and tip it down no need to take off the sway bar. USE A IMPACT GUN the bolt comes off stupid easy

The stock pulley is CRAZY heavy...

Make sure you're in 6th gear or this will happen

And dont let the wedge rest against the control arm or this will happen
