quick question

[gsxr141]

i need a new power steering pump for my 90 supra. is there an easy way to tell which kind i have without getting the car in the air?
there's 2 choices....... one with hydraulic reaction, and one without.
i found that cardone has both, but i don't want to order the wrong one.
thanks bunches..............

Look down at the rack on the intake side of the engine bay. Is there a 2 wire solenoid on the rack?

I have never heard it called hydraulic reaction, we call it PPS (progressive power steering)
