Steering Quickener
When I started the process of installing a steering quickener in my car, I was amazed at the lack of images or threads about it on the internet. Either nobody uses these things, or they just don't bother posting pictures of them. In any case, I figured I'd do a favor and post up what I did so others can see.
The car is a dedicated autocross EP car (86 Civic), and my intent is to allow me to not have to shuffle steer/ go hand over hand during tight slaloms. The new steering ratio gives me slightly less than 2.5 turns lock to lock, so it should be nice and quick, but not crazy. The rest of the steering system is a Civic sedan power steering rack driven by an MR2 electric steering pump.
This is the steering quickener I used. It is nice and small and very light.

I had to cut the Honda steering shaft and weld on some splined couplers to match the quickener. This was not easy, as it was difficult to align the couplers with the shafts. Proper machining equipment would have made it easy (a lathe), but It turned out perfect with simple hand tools and some patience.

To hold the quickener to the body and support the steering wheel end of the shaft, I had to fabricate some brackets. This shows the whole steering column assembly:

And finally, the assembly in the car:

cool. nice install. a buddy has the same one (i believe) on his integra rallycar.
any other pics of the car? looks awesome (love the batt. location)

Lots of places carry it, however they are made by someone for Coleman racing.

rotten,
I didn't even know there was a three bolt version - interesting. I'm assuming from your pictures that you are relying on the single set screw that holds the coupler to the input of the quickener as the only mechanism that keeps the steering wheel from pulling off? I was a little uncomfortable with that sort of configuration - I don't know why, but it just bothered me a little. I'm pretty sure I've well over-built my bracket, but I wanted to make sure it was nice and tight so I don't have any slop from the quickener install.

In the new and unused condition I would say it has no rotational free play. At least there is none that I can feel. It does have a tiny bit of radial play, which is one of the reasons I was concerned about mounting the steering wheel off of it without an additional support.

This is a video on a quick steering mod looks just like that one

hello guys, have anybody use that quickener for a long time? i want to install one on an ek civic which is used everyday. how much durability do quickeners have? how fast in everyday using will distinctive free play occur? and finally what producer better to choose?
Nope
Power steering or not? Which chassis? Quaife make some quick steering guts for the manual steering EF and EG racks. The EF parts make it really quick @ 2.4 turns lock to lock, but Quaife claim 2.8. I have it and it's 2.4. EG, not so quick. I think 3.25.
the integra power steering pinion gear into the ek rack drops you to about 3.2 ish lock to lock. Im at 3 "LTL" because of tire rubbing though. IMO this is good enough for the street, its enough difference that you notice, but its not so much that you can't parallel park. I guess if you retained powersteering it wouldnt matter as much. The only reason i could see something quicker being a benefit would be autoX
there is an virs civic which already has rack with about 3 revolutions from lock to lock and it seems to be insufficient. i have some experience on an impreza spec c with very short rack and i very liked it. i think that 2-2.5 revolutions from lock to lock with power steering would be quite comfortable for street.
as for safety. i don't think that quickener can come apart without any signs, and in any way civic with quickener is much more safer than russian cars

Would i have to take 'roids to be able to turn the wheel in a parking lot? Lol.

I have a Coleman 3-bolt 1.5:1 quickener in my EK rally car. It is about 2.2 turns lock-to-lock as I am using a 99 Si rack which was about 3.3 turns stock. Notes:
-There is noticeable play and the feel/feedback is mostly gone.
-I spliced/grafted/welded the ends of the stock steering columm onto the quickener ends so nothing can ever come loose(the car takes an unbelievable beating on rough gravel roads). Similar install to rotten.
-I had to modify the bypass and output valves of the EK power steering pump so I would have more assist at higher RPM(took 8 tries to make it work). I cannot imagine trying to steer without power assist on 15 miles+ of twisty dirt roads with rocks and ruts trying to yank the steering wheel out of my hands every few feet. Even on smooth asphalt it could get tiring without assist and 2.2 turns.
All in all though the benefit to a rally car is that it is much easier to catch slides at higher speeds. This is what makes the quickener worthwhile. For road racing where fast means smooth and scubbing as little speed as possible is the way to go(opposite lock is not the fastest way around a track), I would probably not install a quickener. For autocrossing where tight slaloms and quick direction changes can be a real problem, I would try a quickener with power assist.
My 2 cents.
