RB harmonic balancer / Crank pulley assy

[Genpac]

Is the Harmonic Balancer and crank pulley interchangeable from RB20-25-26? Or perhaps another engine platform?
I have the typical chips from the front of the pulley and it's causing my power steering belts to get eaten and chucked. Aside from a several hundred dollar aftermarket replacement, what do we know is compatible?

I know the rb26 balancer is different from the others but I'm not sure if it would affect the actual balance I would think not as long as the weight is evenly distributed around it, but the belts are different they are 4 rib instead of 3. I had to get a RB25 balancer for mine and just wanted to let you know it took a few weeks to get but mine was new from nissan japan through nismoparts.com for $100. Hope I helped a little

Thanks, Ghost. I'll look into an OE replacement if I can't find one used quicker/cheaper.
