Help! Looking for belts for JRSC
 

Is there an alternative to purchasing belts for a JRSC?

I purchased a JRSC for B16a1 (Civic Si), but I am mounting it on my B18c5 (ITR), I need the following? But can I purchase them from somewhere else for less, if so part numbers please.

051-110 $15.00
Belt - 4PK800, Crank to Alternator

051-263 $15.00
Belt - 4PK620, Alternator to Supercharger

Thanks

take the belts part numbers to advance, autozone, or napa and see if the can cross referense them. The 4PK800 and 4PK620....

Re: Help! Looking for belts for JRSC
 

if you go to napa the part numbers are 4pk800= 25-040315 and the 4pk620= 25-040245. i work for napa and i am currently at work reading this thread. hopes this help you

autozone would be 800k4 and 620k4 respectfullly. it's an 80.0 in belt with 4 ribs and a 62.0 in belt with 4 ribs.

And if they don't have the belt in 4 rib, buy a 6 rib or an 8 rib (or even a 10) and cut it down. It's super easy, and if you get an 8 rib, you can make 2 - 4 rib belts out of it.

Thanks all!

So autozone couldn't help me. Those part numbers given for autozone didn't work. They also couldn't cross reference using jrsc numbers.... What size are the two belts?
