Does anybody in this forum ever do this?

I just viewed a website:

http://willbelayforfood.com/rsx/rsxmainsite/EPS_Install.htm

thinking to try it on my accord.

Does it possible?
Need advice.

I have an EPS set up in my Accord.

I thought you were going to do a EHPS set up?

Not very sure which system i'm going to use.
Just want to get rid of P/S pump from my engine to save some HP.

That's understandable. EHPS is simpler and less expensive. It's also a lot less work than the EPS system.

With EHPS you need to source a MR2 pump, wire it up and then run hydraulic lines. You're probably best off having a hydraulic hose with a crimped on high pressure an fitting made. I wouldn't trust running regular an lines and hose ends for it.

EPS is a lot cleaner looking. It will require a lot more work though. You need to remove the sub frame and put it in a press to make clearance for the larger EPS motor on the rack. You can also cut out the area and reweld it for the same clearance. You also need to source the rack, EPS controller, wire harnesses and wire it to your ECU. It's definitely more work and more expensive. If you decide to do it, I still have all my wiring notes and can help you out.

Thanks, may i ask to send the wiring notes to my e-mail? This will very helpful to me.
My e-mail address is tandy_utama@hotmail.com

I'll look them up this weekend.

A friend told me can do it with complete swap with cl7 euro-r or japanese inspire uc1

Parts will be a lot easier to find for the USDM Hybrid Accord. The UC1 Inspire has a different sub frame because of the J30. The CL7 Accord also uses a different sub frame than the CM Accords.

I live in RHD country.

What do i need to make EHPS on my car?

EHPS would require a Toyota MR2 electric ps pump, a hydraulic line from the pump to the rack, a relay and wiring and an ep3 or k tuned idler pulley.

Do i need the pump ecu? What kind of mr2 car's pump? Are there another options beside using mr2 pump?

There are 2 generation mr2's, I just don't remember the year off hand. It's just a pump, so it only needs power. No controller/ECU necessary. It's just on/off.

Look on Karcepts site. They sell a kit for it with a bracket.

Thanks for the website information bro.

No problem. They did a good write up on k20a a long time ago.

I think it was 95 mr2 I remember looking it up for you.

There are 2 generations of mr2's that use an electric pump. I don't know much about them, but I believe it was the last 2 generations.

Yes, 91-99 mr2

Hi Tim, could you show me a list If I would like to convert my 07 CM to a EPS setup. Do you have any other suggestions for change steering ratio as the OEM set up is 3 turns from most left to most right. I like 2.5 even 2.0 turns.
Cheers!

The list is fairly short.  You would need the EPS rack, EPS control module and the EPS wire harness.  I'd have to look up all the part numbers.  I have no suggestion on steering ratio.  This is something I have never done any research on.

which car are all these parts from? hybrid accord 07 USDM? I'm glad to wait for your part number list. BTW,If the EPS computer needs to wire to ECM to aquire information such as vehicle speed, how do you think about it?

You can use the rack from a USDM 05-07 Accord Hybrid.  Yes, the EPS computer needs to be wired to the ECU.  That's how I have mine set up. 

I'm going to give you a basic list of parts.  It's not the complete list because you can't just buy a complete EPS rack.  You will need inner and outer tie rods, boots, and other small stuff.  Also, you can find this stuff yourself if you look online.  Most parts sites have part numbers.  This isn't something that I have special access to.

53601-SDR-930 - EPS rack
39980-SDR-A01 - EPS control unit
32421-SDR-A00 - EPS wire harness
32125-SDR-A00 - torque sensor wire harness

Thank you Tim, I went through partsonline for hybrid and saw these key parts you provided, I saw a long list which could be necessary for this job, I think before i confirm the detail I need to find the work shop manual firstly to make sure I'm not missing something.
Cheers!

Tim, I remember somewhere you mentioned the EURO CL7/CL9 subframe is different with CM, then if sawpping EPS from that car to CM chasssis I would need to drill/modify the subframe to void room for EPS, I'm not  sure how do you confirm that information, the easiest way for me could be a CL7/CL9 EPS setup from my understand, but I'm not sure cause I dont have information, I have only CL7/CL9/CM1/CM2 work shop manual , they are in a same book together so I guess they shoudl share sub frame.

I can only say that the EPS rack does not clear the USDM TSX sub frame, just as it does not clear the USDM Accord sub frame. Extra clearance will need to be made. I cannot speak for the Euro R or other cars.

I know its a little late but here is where you can get some info on ratios, turn lock to lock etc.

http://owners.honda.com/vehicles/information/2003/Accord-Coupe/specs#mid (http://owners.honda.com/vehicles/information/2003/Accord-Coupe/specs#mid)^CM7263JW

4cyl: LTL 2.98, ratio 15.21
6cyl: LTL 2.93, ratio 14.95
6cyl 6spd: LTL 2.75, ratio 15.25
Hybrid: LTL 3.17, ratio 16.25

remember even though lock to lock might be look "quicker", it also can mean the wheels don't have to move that far from one side to another = bigger turning diameter.
