Electronic Power Steering

Has anyone seen/swapped electronic power steering on a TSX that originally has hydraulic? If so what parts were used and how was the swap and how did it perform. Any info or redirection would be appreciated. Thanks!

You are planning to replace the TSX power steering with EPS (Electronic Power Steering) ?

Not too sure, never heard of it being done before.
I understand its kind of a ehhhh mod but after driving a 2013 rdx with eps it's amazing how much smoother the steering is. It also keeps the motor from bogging at idle or low speeds. I understand you lose "feel" when changing but it's not something that would bother me.

You can't use any of Honda's EPS systems with the LHD CL9, including that from the CU2 TSX. You must use the hydraulic rack.

You can use a 2nd gen MR2 electric pump for a custom setup, removing all engine-driven components from the system. I'd advise against using the more commonly used 1st gen MR2 pump; much higher current requirements and worse/harder to service motors in the pumps.

The 2nd gen pump also has provisions for speed signal input, reducing pump speed.
Im pretty sure the EPS from the CL7 is a direct swap. I cant say for sure but the subframes are not different.

RHD rack + LHD vehicle = :dr:

Good luck actually sourcing a LHD CL7 EPS steering unit; im not 100% positive it even exists. I know the ABA-CL7 Euro-R's have EPS, but I don't think the DBA-CL7's base 2.0's do. As far as I've seen/been able to find information on, there aren't any true LHD Euro-R CL7's, just conversions like Malkolm's.

I could be wrong though :thumbsup:
Hmmm it's starting to sound like more trouble than what it's worth. It sure would be nice though.

Ah crap, I didnt even think about that part :/ I believe you are correct.
Aren't the Euro-R from Europe Left hand drive or do these cars come with the k24a3 and just badges Euro-R?
I think Accord Euro-R are only RHD with K20A.

I don't know with other Accords (LHD) in Europe comes with ESP.

The LHD's outside of North America are either a:
2.0 Base with a K20A3-equivalent, with hydraulic rack
2.4 Type-S (or equivalent) with a K24A3 (K24A2), with hydraulic rack
2.4 diesel, hydraulic rack
2.4 AWD Station wagon, also with a hydraulic rack from what little information I've been able to source

Any LHD "Euro-R" is a hydraulic-equipped base 2.0 or 2.4 with Euro-R parts swapped onto it, like our TSX's rocking Euro-R goodies.


The MR2 conversion is very straightforward and easy. The only reason I haven't done it on mine yet is a combination of being busy and lazy :lol:
Good info. I just found a few instances where people used the mr2 pump. Both didn't say much about how it performed.

But from the two that I read it doesn't matter wether its LHD or RHD. You just have to have a electric hydraulic pump and a good way to mount it.

Hey Adam, have you had any thoughts on placement or how you would mount it?

there was never any Honda Euro-R aka "CL7R" for Europe market (LHD). Only simple CL7 with 155HP.

Euro-R only for JDM ;)
Have you driven a 06+ Si? I hated the steering, and overall loss of feel (for what the wheels/tires were doing w/the road surface). Far better feedback with the TSX hydraulic p/s system. To each their own, i suppose.
