I know a lot of us JRSC guys having or had problems with our belts and pulleys and a lot of time we hijacking other threads because of it, so I thought it was a good idea to start up on a thread just about jrsc belts and pulleys. The thread is not only for current jrsc peeps but also for the newbies as well so they won't get us frustrated asking the same question over and over again.

I'll start off with one question, I read around and found a member who is using a goodyear 070775 belt which is 7 rib and 77.5 inches long. I tried a dayco belt that was 77.5 long and it wasn't even anywhere close to fitting onto the 3.4 pulley. The dayco 78.9 belt fit extremely well for the purpose. What I want to know is that anyone else tried the goodyear 77.5 long on a 3.4 pulley or is it because different makers make belt a little bit different in length.

Have you tried 8th Gen Civic or any of those other K-motor sites? Maybe some of those guys have your supercharger installed.

Im on 8thgen all the time but 99.9 percent of any s/c guy has the comptech kit. They are not many people with the JR kit that I know of in an 06 + civic si. And I have also took a look at k20a.org to see if anything was there as well. Came up empty. All I have seen if they did have my kit but a 3.4 in pulley or a 3.6 even 3.8 but nothing about the belt size on a 3.2 inch. And I figred it would be different size belt if its on a different size pulley.
