Are these pulleys the same??? Will the RB25 crank pulley fit the RB20 motor?

They are not the same but, the RB25 pulley can be used on the RB20 with a 3 rib belt for the power steering pump.

Search. The guy in classifieds that posted right above you had one for sale for 50 and the guy that posted below you had some for sale for 50 as well.

Ricky, do you have a photo of the 25 vs. the 20 pulley directly from the side? I am having belt alignment problems and the only thing I can think is that is its from me using an rb20 pulley with an rb25det water pump pulley etc..

Thanks, I really need to get to the bottom of this. They don't look exactly the same in your photos on the blog.

I'll get other pictures done here shortly (sometime this week when it calms down) so you can see the differences. But all, RB20 RB25 RB26 rear most pulley (water pump, alt, crank) is located in the same spot. But to verify I'll get those pics.
