What is the crank nose diameter of a CA?

[float_6969]

I'm sick of not having an underdrive CRANK pulley available for the CA (I've seen the lightweight accessory pulleys), so I'm going to see if I can't find another one that will work.

Anybody got a CA crank with no pulley on it they can measure?

If nobody chimes in by the time I get home I'll get you the number. The RB crank pulley is the same size though if that helps.

nobody eh?30mm

Well that's good news. The RWD KA crank nose is exactly 30mm as well. I'm due for a timing belt chance on the CA soon. I'll try putting my KA crank pulley on there and see how the accessories line up.

Anybody know about the SR off the top of their head? I've heard you can use an SR pulley kit on a KA, if so then that would increase our options even more.

well the RB one slides on but the pulley sits to far down on the snout, it would need a collar for the belts to align. The pulley diameter is bigger to.

if the ka one fits, the sr ones do too eh? i know a lot of guys use the sr crank pullies instead of the ka.

why they trying to under drive the accessories?

didnt u hear? New JDM trend that keeps popping up.

no clue man.i dont even know what the point of an aftermarket crank pully is on a turbo motor. its so much easier to make power.

because rusty steel looks like ****? I checked because I want a vibration damper and they make one for an RB.
