What size belt?

Found a pretty good sized nick in my SC belt.i have never replaced it from when I bought the car with the stock M122 with a 2.6 inch Metco pulley and stock balancer. I currently am running a stock lower on a 2.5 inch pulley from VMP on my Gen2R. I have a tensioner as well. Anyone know what size belt I would Ineed to buy?

Not familiar with your car but the belt has the number on it. Any parts store can cross reference it if it’s not a gates.

The below belt chart at Revan Racing should help.
Gates Racing Belts

I'd get stock sized. They're generally 84", 10 rib. Sizes vary a few fractions of an inch depending on who makes it. Gates does offer their RPM series in that size.

Thank you guys. I appreciate it.

84” seems to be the belt for most, I felt the 84 was a smidge loose with my 2.4, so I want to an 83.* something belt in the Gates racing.
Maybe 83.7?

I ordered the Gates 84. It says it shiped at 1:05am today so should have in a day or 2. The model number I ordered was the 840L10. I have that auxiliary idler too. The belt that's on it has no markings that I can see.

Great! Interested to hear how it fits when you get it installed. I've got a similar setup to you....

I received it this past week, but actually didn't install it this weekend. I will let you know. Should be this weekend at the latest.

^^^How did it go?

It hasn't, I was chasing some other issues and actually had it up on the lift to do the belt and the charcoal canister purge valve. Did the canister valve and lowered the car did the evap purge solenoid and went for a test drive before I realized I forgot to do the belt. I will update when I actually do it. Won't be too many more weekends, lol.
