rb20 with rb25 ps pump

[jluck113]

i was wandering if anyone had an idea if the rb25 harmonic balancer is the same weight and balance as the 20 , i have access to a rb25 balancer and a ps pump so i can run the more common pump with the right 3 rib pulley. any help would freakin rock NO PS SUCKS A** !!! i say that after only 2 mos of being without

I used a Neo RB20DET power steering pump and bracket (looks just like rb25's). I'm not sure it's lining up right tho, my belt started to hit my fan so I just cut it off. I'm going to double check it again and if it's not straight just swap in the S14 power steering pump.

thats why im asking more about the harmonic balancer. the ribs on the pulleys are different from the rb25 pump and hb compared to rb20 but i have access to both hb and the 25 pump and bracket from a buddy for dirt cheap and just want to know if it fits the crank and if the balance is the same , also that may be your problem with it lining up i would look closely at the ribs on the pulleys to see if they are the same . from reading up for a long time now the rb20 stock pump and a s13 hicas pump are the only pumps that bolt up to the hcr32 motor .
