I remember trying the pulley kit on the RB25 and I belive the alternator and water pump fit correctly but not the ps pump. I still have the stock rb26 pulleys so maybe I'll try and find a way to get the ps pump pulley to work...

There's also an RB20 pulley kit.

I've been wondering if that one would work on an RB25.

They're located in Austrailia, so I would think not.

BTW, I've emailed Unique Autosports to see if the RB20 set will work on the RB25, or if they know of a part number for the RB25 set.

If you guys want.Unorthodox Racing has pulleys that fit the RB20. I have them on my motor now.Water pump and Alternator.If you want part number's your gonna have to wait until after this weekend, because I'm going to recheck my timing belt.

I know there 300zx parts though.Can't remember if they'll work on RB25's.

26 and 25 water pump pulleys are different size but it will line up.

26 ps bracket puts the 25 pump too far (forward i believe, dont remember exactly which way) so that will not line up.

rb25 ps bracket and 20 brackets are interchangeable. pretty sure their pullies would be compatible but i have not tried first hand.

i'm pretty sure the alignment of the innermost drive on the crank pulley (alt/water pump) is the same on all RBs, although actually pulley gear size varies.

So based on what you're saying here, the RB20 & RB25 kits would be identical?

I'm asking because the answer I've received so far from the Aussies were vague and unhelpful.

The GReddy kit is only water pump, alternator and power steering.
