Power Steering Relocation

[VETTE_50_TH]

So they make a alternator relocation, does somebody know of a way to relocate the power steering pump in the same fashion, or no? I was thinking about getting rid of it on my new talon, but not used to driving the car with no PS. I did do it for a little while, when my hard lines on the rack cracked and had to drive home. It was a bi***. So, i know the feeling, and its not bad when at driving speed. Anyways, is it even possible to relocate the pump or not worth it to relocate and i should just get rid of it.

I would like to know as well.

Posting just to keep an eye on this thread. I am interested +3 to know if there is a way to move it around. I got a few more go mods, but next up is engine cleaning up, so moving that stuff somewhere else would be cool.

I don't think that just moving stuff around the engine bay is going to be what you are looking for. I think it will only make things more complicated as you will have to run lines to the back of the block, where I think is the only other possible mount point (given you have not already stuck the alternator back there). This being the case, I think the best option would be to switch to an electric pump, like the Toyota MR-2. This would allow you to not only mount the pump virtually anywhere, but from what I understand has quite a few benefits over most conventional pumps.

Elaborate please. How would we need to wire our current plumbing? Im not interested in doing it but this is a cool idea.

I relocated mine to the trash can.

this would be very helpful for 2g's because we dont have the option of simply installing a manual rack.

Instead of having the pump driven by an accessory belt, you would run an electric pump, which you could mount underneath the apron panel behind the front bumper, or anywhere else. Then you would need to mount a small resevoir down there as well, and then run the lines from the rack to the pump, which you could hide fairly easily. You would need to wire the power to the pump using a large relay, as the pumps need to be able to draw a lot of current when under load. This roughly how I would set it up if I were to do it, but I do not have any more details than that as I have not done it myself.

What year MR-2 pump would we be looking for? And what are all the benefits/drawbacks of running an electric pump? And for those who are not running P/S anymore, please understand that those of us running wide tires need it for autox/road racing. Pulling it out is not really an option for us.

There are 3 different types of power steering.
1) Hydraulic (HPS)
2) Electric (EPS) and
3) Electro-Hydraulic (EHPS)

The Electric power steering (EPS) uses 100% electric power for steering and does not use any hydraulic fluid or hydraulic pumps. These are used on cars like the Acura NSX and Honda S2000.

In an EHPS system, the the engine drive pump is replaced by an electric pump while still using hydraulic fluid for power steering. The pump on the Gen II MR2 is an EHPS. The last thread states '92 - '93 pump.

Benefits:
- Allows removal of the engine driven power steering pump
- Less power steering lines

Drawbacks:
- Power sucker (80-100 amps)

I have yet to see anyone convert a HPS on a DSM to an EHPS.

Looks like it might actually add some weight though with that new pump... hmmm, not as cheap as I would have thought either. Might still consider it though later this season.

You can gut the rack out by removing the seals and lube everything up..?

i removed my ps to save weight.. so far steering hasn't been an issue...effort is needed while not moving..but its not as hard as say a Cadillac xD or large truck..

i left the lines, and fluids in place, and plugged the line from the pump.. which needs to be plugged better..the paper i put in there doesnt do the job and a plastic bottle is now a catch for any fluid that comes out of that end..

mostly left the fluids and lines for lubrication..as i wouldn't want to take the rack off and lubricate it 3 / 4 times a year or more...just swap out fluids.. wondering what kinda oil i can use in it.. possibly plain ol gear oil..

i'm still wondering if everything is getting lubed up tho...

I relocated mine to the trash can.

I like that relocation!

 

[VETTE_50_TH]

I removed the hardlines for cooling off my car and it worked fine. No issues.

 

[Ludachris]

I think we have two different groups here - the people who are doing modifications and driving the car around on the street and the other group that races their cars on the weekend. When someone says, I did this and have had no problems, it would be good to explain your application so that a weekend racer doesn't come away with the idea that it will work for him with the abuse that his car sees. If I removed my power steering cooling, I'd have serious problems at the track - yet it would probably work okay for normal street driving.

relocation = electric pump

Since i still haven't found a manual rack for some reason... I just want to keep fluids moving through the rack.. so as it is the return line, is just hanging off the resivor...I was thinking i can just remove the cooler, then run a line to the return side of that? And it would cycle??
