hey guys looking to pick up a smaller pulley to run some more boost, the setup is going to be k20a3 jrsc-r (ep3 spec), k tuned fuel rail, 650cc mototron injectors, password jdm cf power chamber intake... my questions are... would you change the crank pulley? and what size belt would i go with for this setup? can anyone recommend or share a link for said belt?

How large is the crank pulley on the A3? I have a k24 crv pulley and 3.4 blower pulley. I'm running the 6 rib 64 3/8 belt with a 90mm tensioner pulley.
