I have a set of Blue aem tru power pulleys for sale. 100.00 shipped
They 100% sure fit a 90-93 integra, other than that, I can only speculate.

- This is for Power Steering and Alternator
- The PS is for a V belt
- They made a nice differene on gas mileage per tank, power wise they might have made a difference, but I am not sure they were installed the same time as an intake, so I would be speculating.

They definitely enhance the engine bay!

 

Thanks Mr. Moderator, perhaps you can scavenge the entire site and clean up all the scattered posts.
