This is a very deep subject with not a lot of information about steering units. While most quick ratio units are of the recirculating ball type boxes there are a few rack & pinion type. Almost all quick steering units are also hydraulic assisted. This means you need oil pump/tank with them, usually powered by a belt to the engine. there are a few manual rack & pinions like the mustand, subaru, a few toyota's and nissans. The quick ratio units are usually around 16 to 1 with some down to 14 to 1 ratios. Standard ratio for auto's is 18 to 1. Most standard ratios have a lock to lock of 3.2-3.5 turns. Even the quick ratios will still have a lock to lock of 2.6 to 2.8 turns. There are a few R&P's with a lock to lock of 1.7 turns, but good luck finding them.
Here's some good information sites:

Something to think about in the above website is the electric R&P's for power assisted steering

Meanwhile i would look into the Polaris and Can-am R&P units as they are very suitable(if expensive)as they are already street certified. One thing i don't like about the polaris large ute's is the steering that looks almost like gokart style steering.
Since i have decided to use handlebars instead of a steering wheel my choices are limited. what i am planning on is using 2 large chain sprockets(bicycle type chain) with handlebars attached to one sprocket and the other sprocket mounted in front of the engine with a shaft going down to a automotive type pitman arm. Heavy steering at slow speeds? probably but not enough to cause me to go to the trouble of putting on Power steering(it is a possible option).
