    I'd be most grateful if someone would be kind enough to let me know how many turns a Mk3 takes to turn the steering from lock to lock. I'm considering using a Prius rack on a project car, but never having driven one, I have no idea!

    Something like three or two and three quarters or 2 and 7/8 I believe A Prius rack on a project car you mean you want an electric rack You know the rack isnt electric the steering shaft is electrified there's a motor above your knees I'm guessing you know this so the input from the steering wheel goes through a motor assembly if you will right above your knees which turns a steering yolk which in turn turns the spleen shaft on the rack which moves the tie rod ends so it's essentially a manual rack so thinking a little backwards you might be able to take the steering shaft assembly and motor and the yolk and make that work to about anything you want within somewhat reason I imagine there's a weight limitation or something along that specifications for the motor and the steering effort and all of that stuff. You do know that TRW made a complete electric rack also not steer by wire or anything like that similar to the Toyota set up I do believe but I think it's all in the rack not in the steering column or shaft The guys that spend their time with the electronics on this car will be a long shortly to tell you something I'm sure but seems perfectly plausible to use in other carts etc I shouldn't really be an issue I'm not sure how much computer input and what not is needed or what exactly works the electric motor for the steering whether there's any computer aided business going on doesn't seem like it I've had a few of these in generation twos that do funny things It seems like the motor that's giving the steering boost is pretty cool it's like on some kind of geared shaft and if you have the wheels off the ground or if the car is on and ready you can move the steering wheel kind of quick and then backwards and you can feel gears kind of catching up with each other or something so there's something going on that provides some kind of feedback and all of this kind of business so then just fitting the steering column from a generation two or three Prius to whatever steering is already in the other vehicle If it's not power I guess or if this is a home built then it's not power the steering shaft should be able to turn your I assume rack in your built vehicle if all the splines will slip up.
