Where to find new steering rack for Gen. II?
I need a 2nd gen. manual steering rack and steering linkage shaft for my project. Anyone know where I can buy something like this new? I've never shopped for 2nd gen. parts before.

Since you save everyone else money, maybe I can do the same for you.
I ordered a new manual steering rack (fresh reman.) from www.mazdasurplus.com for $35. It's listed for '86 - '88, but it fits in my '90 just fine. Not like that last bit of info will help you, though.
Mazdasurplus charges a $50 fee if your order is less than $2k, but still a great deal for a brand new rack! One caveat - it doesn't come with tie rod ends, so you might swap out your 3rd gen's tie rod ends (if the threads match up).

To answer Cash Money's question, there are some questions about the strength of the 3rd gen. power rack when power assist is removed and the rack is converted to "manual" use with a recirculation hose. The last thing I want to do is find out that this is true at or over 200 mph...

Jim,
If you don't get it elsewhere, I have a manual rack here, for sale. It won't be $35 though, more like the usual market value for a working used unit, about $100.

Jim,
Make sure to jump in on our group buy at Mazdasurplus that is going on. We are dividing the $50 fee evenly over all the members. So, less for you to pay in the long run.
Thread is around the 2nd Gen forum somewhere.

Yes, this is the part - The rack looked better than new when it arrived!! The boots were brand new, the sticker was brand new, the thing looked perfect!! The two bolt mounts and rubber isolators are already on the rack, as well. Keep in mind it's not a Mazda brand part, rather a reman. unit. By far and away it's a steal @ $85 ($35 for part + $50 fee)
Maybe even polish the steering gear housing before installing???
See: http://www.iluvmyrx7.com/Technical_I...ing_system.pdf
It's part# 4 on page 3, minus the rod ends.

Shawn

there are some questions about the strength of the 3rd gen. power rack when power assist is removed and the rack is converted to "manual" use with a recirculation hose.
The "speed" of the steering will be significantly reduced with the second gen manual rack when compared to the third gen. The 2nd gen manual has a significantly higher steering ratio. It will require less effort to turn, but one has to turn it more to move the wheels the same amount.
I don't remember the exact numbers but the steering ratio of the 2nd gen power steering is higher than the 3rd gen power steering. The steering ratio of the 2nd gen manual rack is higher than the 2nd gen power steering(This makes mechanical sense).
I am not sure if the steering ratio would be affected by adapting the 2nd gen manual rack to the third gen but as a fan of road racing, I have a feeling that I would dislike not having the fast steering of the third gen. It may not matter as much to you since you are more into straight lines.

PS Let us know how the steering response is if you do switch to a second gen manual rack.

Jim: do you know the 2nd and 3rd gen i-shafts to be different sizes?
I was thinking the 2nd gen rack would drop right in to a [3].

For the 3rd gen. it's only 0.6 of a turn farther lock to lock (3.5 - 2.9), so about 0.3 of a turn in either direction from dead center, unless I'm way off base. That ain't ****.

unless I'm way off base...
For the second gen, the difference between power and manual rack in terms of turns for lock to lock is (3.5-2.7) 0.8 which I think is significant.
Cymfc3s feels that it is not significant but I think that only back to back testing between a manual and power steering car will elucidate this.
Anyhow, I think that even if it is only 0.3 increase turn in either direction, this would be quite significant in fast steering situations such as in negotiating through a slalom.
But only further testing will give us the real answers in terms of subjective as well as objective data in regards to the performance feel and interchangeability of steering components between 2nd and third gen.
Please let us know how this goes.

I do know that Dewain Thomas and friends used a 2nd gen. steering rack on their track-only FD. I have to assume that if they chose to do this, that there A) must have been some good reason, and B) they found that it worked more than adequately. Unfortunately, I haven't been able to reach Dewain to confirm that.
