k20z1Ctsc k24a2 with 3" bp , anyone know what size belt can I use on it?
Just wanted to update everyone. I have this exact same set up and used the 4080815 and it worked great for me as well. I def recommend trying to loosen the belt up a slight bit before installing however you can though. It was very very tight going on, but once it breaks in it's going the be perfect fitk20z1
jmercado bracket no spacers
3.0 blower pulley
k24 crank pulley
4060815 or 4080815 ( cut extra rib, its what i did)
If you wold of read thru all of the thread you would of found this.
This will only work for you if you have a jmercado bracket.
Not sure if the same belts wrk with ctsc? I would think they would though.
