I posted a month ago with questions about installing a 99-00 civic JRSC, on my 95 civic. Well I got it installed, but the 92-95 SC belt I ordered from Jackson is not long enough. I know that the 99-00 kits come with a crank pulley, but I didn't install that on mine. So I'm using my stock crank pulley, and the 99-00 SC pulley. So I guess that the SC pulley is different for the 92-95's compared to the 99-00's. Anyone know for sure? Also wondering if using this pulley will increase or decrease the amount of boost. I hope I don't have an upgrade pulley. I guess that is possible. The stamp on the pulley says 4.2.
