Ive also briefly thought of this. we've noticed that the return line is large, and thought maybe changing it to a smaller size would increase the pressure and help out. Of course too much pressure and we would blow the seals... another thought was to do the s14 rack conversion

that would be amazing if you could! I wouldnt mind the steering if it was a track only car, but being a daily driver its a pain.

the feel of the steering never changes, never is light then gets heavy. Just always heavy. i have an rb20 transmission and the speedo works fine at the same time I installed a r32 boss hub and nardi wheel, it turns off the signals just the same as the oem wheel did(the oem wheel didnt turn off the turn signals all the time but the steering felt fine) is the steering assist thing on the rack controlled by the HICAS ECU? where can i find a wiring diagram for a gtst?

Well we plugged in the solenoid on the rack and made sure the wires were conductive and still pretty heavy. So, I have been reading that if the HICAS ecu reads something wrong it will go into limp mode right? well I all the lines and anything related to HICAS except the HICAS ECU and rack solenoid have been removed. Will it always be in limp mode? Do people that have HICAS removed just have to live with the heavier steering? (Ive learned the heavier steering is because the car always thinks is traveling fast and so it stiffens up the feel?)

Hello all, My 90 R32 GTST has recently finished getting an RB25 swap. During the swap it was decided that we remove HICAS and use the RB25 power steering pump (from a C34 if that matters). Unfortunately my steering is quite stiff, not to the point where I would say not working, just not working properly, the wheel does not return freely. What could cause the heavy steering? What is the motor or sensor that is connected to the steering rack? Cause its not connected at the moment (what does it do?) The Hicas ecu is still plugged in, however I snipped the green wire on the smaller plug to turn off the dash light. Is there some sort of steering speed sensor that needs to be connected? where is it located? (could possibly be connected still just throwing out ideas) I also have an aftermarket hub and wheel put on at the same time as the swap, Im pretty sure the hub was for an R32 with hicas but i cant be sure... the turn signals do go off when i turn straight though. thanks!

Hello! Sorry for this being my first post but Im in a bit of a jam. I have an R32 GTST that a friends shop is putting in a RB25DET, we were unaware that it was not an R33 engine at the time, and it was completely confusing as the diagrams and instructions available online for RB25 conversions were all for the R33 engine. We have come to find out that the engine is from a C34 Laurel, not just because the ECU was lightly scratched "koki Laurel" but also because my friend at the shop found the C34 ECU pinout from a japanese site. So, the problem we are having is finding the C34 pinout for the dash/cabin plug. Might anyone have this information? thanks for any help Lucas
