Electric power steering pump / Variable PS (1 Viewer)

[Pighead]

Wow. You think big.
I'd be interested in an electrical power steering pump just so I could go back to my big old-fashioned air cleaner...neither of the pump mounts I've tried allow me to use it. I've got plenty of electricity (140 amps) under the hood, so I'm leaning towards electrical OBA instead of a York. And with an electrical water pump, you would lose the stock water pump and then have plenty of room in front of the 2F for a Taurus fan...

How are you planning to fit a taurus fan with the 2F?

What electric water pump are you planning to use?

I haven't seen anything that says it won't fit. I ran the flex-a-lite black magic 150 fan on my old 40 and it came damn close to the center post of the mechanical water pump but it cleared it. The Taurus fan is off center so I think it should clear just fine. If not I can just trim the post on on mechanical pump. Or I could just go with an electric pump. I would need to build an adapter to cover where the water pump is now and then connect it to something like this.

Though I have yet to test this setup, I fit the mini-truck pump where the F alternator sat using the stock minitruck pump bracket with just one minor bit of welding. That then bolts to the stock alternator mount. My F air cleaner fits just fine though it's not on in the pic. IT even has an easy adjust feature.

You know the EPS is just a minor piece to this FJ. I am also going to be running a Taurus fan, at some point an electric water pump, and a Megasquirt 2 Extra. The MS2extra is going to be getting crank position info from a 3FE Distributor and directly firing a ford EDIS-6 wasted spark coil. It is also going to handle fuel injection for a 4.3 TBI with dual fuel maps so that I can have an economy mode at the flick of a switch. It will also be controlling both hi and low on the Taurus fan. At some point in the future, I also want to put the eaton M62 supercharger on it from a Mercedes Benz SLK or CLK 2.3 litre as these have an AC style clutch with an air bypass so that you can turn the supercharger on and off.

So the EPS is just a small part of this project. *insert geeky nerdy smiley here*

You shouldn't need an economy switch, since its MAP based. Just tune the low load areas of the map for economy and the higher load sections for safe power.Good luck with the EH PS. I own a MR2 performance shop and have never heard of a failed EH pump. I considered going this route too but when I decided on a diesel motor with a built in pump it became irrelevant. Also some of the lexus es250's I think, have a hydraulic cooling fan on the radiator instead of an electric fan. Might try one of those too.Todd

What if you just "gutted" a stock waterpump? Either pull the shaft and plug the hole, or maybe cut the shaft fore & aft of the bearing...theres your adapter, and the stock hoses fit.

Hmmm that might actually work. I pulled an old F pump apart quite awhile ago. Here is a pic.

You remove the backing plate, press out the impeller/bearing/shaft from the front with a press, press off the impeller, cut the shaft then press the bearing back in to act as the seal. Bolt the backing plate back on and your done?

An MR2 performance shop ehh... happen to know the GPH of the MR2 pump?

Dude you get an "A" for the day on that one!!

Hmmm I hope I didn't throw out the onld one I had... Be a shame to rip apart a brand new one.

nope sorry, we never mod the PS! If you need a 700RWHP 2.2L Stroker PM me Todd

hello,
I want to use the MR2 power steering system on my 80 FJ 40, could you let me know where I could get everything need?

Thanks, Bert

Let me work out all the kinks first. I don't want to lead anybody down the wrong path in the slight chance that this doesn't work the way I expect it. I don't want people throwing away money on this if it is a dud. It is going to be a while too. I just bought a house which I won't be closing on for 2 months and then I need to build a decent sized garage on it. I probably will have completed this in about 5-6 months from now. Be patient.

Thanks Joe
I was talking today with a guy who worked for Toyota for years and he told me to go with the MR2 system. So it was funny to read your message on using the MR2.

 

[Pirate]

Hello, Joe

I had another conversation with my Toyota buddy and he is willing to do the MR2 power steering conversion for me, can you tell me what parts and where to buy? I am ready for poer steering and my Toyota guy is pushing to go with the MR2 over the MiniTruck, I'll post pics and let you know how it works out.

Thanks, Bert

Pictures of the PS ECU/Relay Controller/PS Driver loom. The wires without plugs on them go to power, ground, steering sensor, VSS, and the Pump. I will put up a list of what color is what when I post the picture of the loom with the weather pack connectors on it.

 

[joeyg1973]

The VSS on an MR2 sent out 4 pulses per revolution. If one needed to keep the PS pump on longer you could knock it down to 3, 2, or 1 per revolution.

I need to get my VSS split into 2 signals, one for the speedo and one for the PS ECU. I am getting my VSS and wire adapter box from the guys at Speed Service. Speedometer Service of Milw providing speedometer solutions

Just for everyone's clarification, the Taurus fan fits on the 2f and 3b 40's with almost ZERO modification to the existing plastic shroud. Pretty much the best junkyard bolt in ever.

Good for you.

I have an 82 BJ-42 diesel that does not have PS and I do not want PS.

BUT... I have a hydraulic winch that I have been researching a power source for! This will work well. THANK YOU for being curious and searching off the beaten path.

Please drop me a line.

All respect but is'nt youre bj 24volts?, and a transfo to 12v 80amp's is a big expensive thing.
I think a hydrolyc pto pump is a better, bolt on option for you.

just my 2€

 

[Texas bj-42]

It is a 12V from NZ. Do you know of a hydraulic PTO pump that will fit a split case? A P/N would be much appreciated. Thanks.

What was the outcome of this??? Anyone know?
