AE92 Corolla EPS

Ae92 Corolla (88-92) EPS(electronic power steering) pump writeup

You’ll need the bracket, a Volvo pump, a handful of fittings, some electric tid bits and some patience.

Volvo pump
08-13 C30 t5
06-13 c70 t5
05-11 s40 NA or T5
05-11 v50 na or T5

Pressure line:
-2x 90 deg -6AN gen to -6AN ptfe hose ends
-1x m16-1.5 oring adapter fitting PN: Allstar 48210 fitting (pump)
-1x M14-1.5 oring Steel PN 591962 (rack inlet)
-75” of earls EAR-151006ERL AN Hose, Power Steering Hose/ptfe , 10 ft. Length, -6 AN

Return line:
-1x 90 deg -6AN fem to -6AN hose end
-1x M16-1.5 oring Steel PN: 48210 (rack outlet)
-75” of -6AN line

The return fittings/hose ends can be aluminum, the pressure side must be steel or stainless steel.
I used adapter fittings that were steel as well

The routing is pretty straight forward, both go basic at straight up, they 90 out of the rack abd 90’out of the pump except for the hose barb return on the pump.

The wiring I’m using a big circuit breaker and a decent sized relay.

You’ll most likely want a bigger alternator to run this and bigger gauge wiring from the alt + to the battery. My stock alt on my Celica(2grfe engine) works but those are ~160amps stock. Good idea to run big grounds to the engine block/transmission while you’re at it.
You can get a tool to crimp the lugs on eBay that you just hammer down on, and welding wire.
4ga should do.
If you don’t want to invest that much subwoofer wiring kits have enough wire and almost enough lugs to do that as well.

Link to the Celica post for pictures of the pump, the plug type, etc


Waiting to confirm this clears the shifter stuff as it’s very close, if it does it will be a super legit install.
