Re: ReSpeed rack & pinion conversion
Thanks, worth thinking about, do you reckon the steering wheel splines would be the same, only i have a quick new steering wheel and boss for the RX7?

Re: ReSpeed rack & pinion conversion
The steering wheel splines are 100% the same, I ran an FB steering wheel in my mx5 for a while and vice versa. The control stalks also look identical, to s2 FB anyway.

Re: ReSpeed rack & pinion conversion
Once I start to get it set up, I will post the progress, good and bad !
Be a while yet tho, but i have nearly all the parts i think i need, the rack mount to crossmember is the trickiest part.

Mk1 MX 5 Steering column bought and on it's way.
The rack will need to sit in the same position as the steering tie bar so that it clears the sump/gearbox bell housing.

Re: ReSpeed rack & pinion conversion
I like where this is going. Any updates?
BTW -- there are US companies that will modify OEM racks --> http://www.unisteer.com/seach_by_vehicl ... ength.html

Re: ReSpeed rack & pinion conversion
No movement yet, still working on sorting the shell, although looking again at the sump picture, it will be a challenge to get the rack in there, support could be the main problem.

Re: ReSpeed rack & pinion conversion
It looks to me like some robust brackets could be attached to the aft of the front lower crossmember. You can do it.

Re: ReSpeed rack & pinion conversion
That's what I was planning, it all depends on the centres of the mounting points on the rack, and if that will suit the width of the sump pan.
I am planning to use a Ford Escort MkII rack, as I can then get a rack that has 2.5 turns lock to lock, we call them 'quick' racks. I guess there are a number of power racks that you could de-power and use, but I thought I would go the Escort rack route initially.
