I dont know the exact size of the belt, i dont know if you can even do it without a delete kit or something. And no, you probably wont notice a difference

go to the parts store and try belts till you find one that fits, I noticed a small power gain and with the pump removed the engine bay looks a lot cleaner

Primetime, how did you route the belt? I always had trouble with the belt rubbing on itself on teh tensioner when i was trying to delete the smog

I am 99% sure I used a 85.4 belt to bypass the smog. I have since then took off the Power Steering as well as the A/C so I no longer have the belt to check.
