Hello all

My engine came with a HICAS ps pump. I bought a used non-HICAS pump. The non-HICAS pulley has 3 ribs and the crank pulley has 4 ribs. Has anyone else noticed this?

I thought about using a 3 ribbed belt and just let one rib on the crank pulley go unused. Here is the problem: The only size belt that will work is a 345K3. I closest belt sizes available are 325K3 and 350K3 both of which are too big or too small.

What size belts do you guys use on your SR swaps for the ps pump?
