Does anyone know of a manual steering rack that is almost a direct drop in for a Series 1?

I got to thinking the other day, and if I recall correctly the Honda S2000 shares the same electronic steering rack as the RX8, and the Automatic trans version of the Acura NSX has the same electronic rack as the S2000, and the Manual trans versions of the NSX all have no power steering.

Would it be possible to drop an NSX manual steering rack into our car with moderate to light modifications?

 

Interesting, I was searching for the same thing.

 

They look different

RX-8

 

subbed



I wonder if one could modify the electric one to become manual?

 

Dont tamper with the electric one, EPAS steering has some nasty habbits that isnt so fun to be subjected to.

 

Your just gonna have to put the two side by side and take some measurements. Jeeef should have an RX8 rack lying around. And if Ravi has an NSX one lurking in the garage then there ya go.

 

I remember watching an overview of the speesource rx8 where they said they have a 3 steering settings that they can adjust on the fly ... I wonder if they would be willing to tell us about it


decent info on the subject: http://www.supraforums.com/forum/sho...ack-conversion

 

I can't find a pic of the manual NSX rack but the mounting points look different on the EPS one.

 

Mounts can be modified .... its not over yet

 

Yeah they do look a bit different unfortunately. I wonder if they are the same dimensions and maybe the only hard part about getting it to work would be finding a mounting solution.

The reason I'm kind of tossing this idea around is because I saw the size of the steering rack on the NSX... it's like 20% the size of the RX8 steering rack. Must be a lot lighter and if I were ever to do an engine swap down the road it could possibly solve the problem of "the steering rack is in the damn way".





Yeah I'm going to have to go to Ravi's some time and just start taking measurements on his NSX.

 

So as I seem to suffer constant and never ending troubles with my power steering system, I was wondering if anything ever came of this as I may be looking for a manual solution...

 

My power steering has stopped working also, I have cleaned the connectors with no luck. I will have to try a more thorough clean and keep an eye open if anyone else has a solution. As long as the rack is the same length and it fits in the space it should not be a problem, depending on how much fad work you want to do.

 

Yeah nothing really came of this, I've been way too busy to attempt anything. I'm sure with enough fab work anything is possible, you just have to be careful to keep roughly the same geometry.

 

The V8 roadsters / conversion folks have a solution that converts Electric Power Steering to Hydraulic Power Steering.

And if you go to a Miata rack, the following is how to de-power the Hydraulic Power Steering from Flying Miata:

How is the handling with these upgrades, are their an videos online with these parts demonstrating improvement? Let me know.

 

Your bumping a thread from 2014, may not get an answer.

 

unless it’s a race car and your goal is cast every last gram overboard, then there is no manual solution.

just letting you know …
