Rb25 Power Steering Pump On Rb20

[pavel]

Hi, I've removed all the HICAS gear out of my r32 and got myself RB25DET p/s pump. It bolts on without any problems but the pulley on RB25 pump is 2 rib compared to RB20 one which is 3 rib. Should i change the pulley on RB25 to 3 rib? or use the existing one? thanks

probably put the rb20 wheel on rb25 pump (if you can get it to work)because the number of ribs on the balancer pulley will match the rb20 pump wheel

Thats what i cant figure out, I've pulled the pulley of RB20 pump (which was held on by a bolt) but the RB25 pulley looks to be one piece or pressed on? Anyone has any information on how to change the pulleys around? thanks.
