K-Series Crank Pulley Diameters

[iDom]

Before I get sassed, I would like to say that I first looked and searched the forums and couldn't find what I was looking for, so.. I would like to start this thread and hopefully fill it up. I have a k24a2 with a k20z3 head, and i'm not sure which Crank Pulley is on it. I already bought a OEM belt for the k20a3 and planned to use that but am unsure of which Crank Pulley is on the engine. (It's either the k20z3 or k24a2 Crank Pulley) I can't be sure which is which without knowing the Diameters in inches, so along with finding the answer to my question, I am hoping to make a thread with some useful info..

Yes, I know I can just swap my k20a3 Crank Pulley from my stock motor over, but I would still like to know which one is on the engine/or if I'll even have to..

Well this has been a smashing success.. Haha

Anyone with any of the listed swaps feel like going under their car or next time they do an oil change just get a quick measurement?

Nice! Thanks

Are you sure about the 03 CR-V being 6.25? The part #'s for the 02-06 CR-V and all the other engines match the 13810-RRA-A02 part number.

Other than that, and besides the JDM engines (which I can never find jack squat when it comes to those) I think that about covers it.
