sr hicas ps pump question

[streetracerb86]

I have a s13 redtop in my 90 240 hatch. The power steering pump that was on the sr is bad so i've been researching and i read that the dohc ka ps pump would fit. I tried it and it doesn't fit. I think the guy that i bought the sr off of said it was a hicas model. Are there differences in the brackets? What ar emy options? Oh and im using the ps pump off of a 91 dohc ka if it matters. thanks for any help im stumped here.

there are differences, you'll need the hicas pump. give marco vargas a call. I believe his website is sr20store.com
