Electric Power Steering

Whats wrong with the ol' rack setup? its not really a problem inless you steering under 10 mph IMO. If its is a problem at higher speeds than there is something wrong with your wheel/suspension setup.

 

Its more trouble than its worth and that costs more than 2 1/2 time more than what I paid for my car. :P

 

 

I'm sure you can find something cheaper if you look for parts from the new honda ATVs if you can find one that is being parted out.

I'm going to do this to my car one of these days. I think that all of the new Hondas have this system now.

 

In my opinion, the stock steering is way too slow, the effort is not too bad unless parking, however if you do anything to speed up the steering, you're going to make it even harder to steer. From what I've read, the electric power steering is simple, light, and its really easy to adjust the gain.

I agree Flexi. I would like to speed up the steering significantly for autox use and run big stickies, and unfortunately I don't look like the guy in your avatar. I'm undecided on electric or not but the Mazda 3 also comes with an EPS rack that looks fairly compact. mazda_3_steeringrack700.jpg

With stock-ish suspension, power, and street tires, its probably not worth the hassle/weight/complexity. When you mount sticky rubber and start getting the chassis to actually work, you find that steering effort increases rapidly with increases in grip. Add in small/tight courses with a torquey V8 and you become very busy seesawing a very heavy wheel. Power assist can be nice :2thumbs:

There a number of these type setup sold in Japan for the S30. I purchase one of the Japanese kits - it like many of the parts I have is still waiting for the body to return from the body shop. I agree with the above and as I have modified suspension (ready a lot more + caster and - camber) having PS for autox work will help. The kit I have includes a speed sensor so the EPS unit is only helping at low speeds at high speeds it is back to the normal zed rack.

 

Here is some pics of the kit that I got from Japan - including a sample installed into a Zed - there is a youtube video of a guy using this setup on the car shown in the sample pic attached. There is some fab work required and I will sort this out later - maybe a job over the festive season ;)

there. a cheaper, less complicated fix

 

Sorry, I'm not following. Those increase steering effort as much as they increase steering speed. It's not the answer to the question, so to speak.

 

Additionally, those serve to reduce Akerman, and in my experience/understanding, is not the best choice. All things being equal, I would prefer to lengthen the steering knuckles.

Wow, they are making these kits for the S30, eh? If you don't mind me asking, what do they go for? $$$

 

This is a very sanitary looking kit...

Nice to know theres a kit out there...we need more info NZeder!

 

That looks just like the setup on a bunch of the GM cars.

Im sure a used cobalt or ion steering column could be picked up pretty cheap, just need to figure out the wiring.

Ive been looking at the Toyota Rav4 system and its hooked up to the CAN bus as it needs vehicle speed and yaw angle from the various other control boxes around the car. I dont know enough about CAN networks to be able to figure out if the signal can be faked easily. Anyone?

I think you're actually getting into anti-Ackermann with those.

 

I think you're right. I've never checked the S30 to see how just how close to parallel steer they are, but we know they're *close*.

Guys as the kit I have is not installed yet - I need to have the body back from the shop. All I can tell you is that the kit I got has instructions in Japanese, the spline where the steering wheel is not the standard Z spline/shaft size so this is why it comes with an aftermarket/momo type boss kit.

 

Re the cost I got mine a while back when the NZD to YEN was not a bad as it is now but in today's market and USD to YEN they go for around $560 USD this is the purchase price then you have to pay shipping etc. I purchased the kit from yahoo.co.jp auction via an agent in Japan so there were his fees - shipping of the unit to him to check and repack then on ship to me in NZ.

 

I know that in UK the Ford Escort and Kit car builders use the Vaxuhall Corsa B or C EPS unit - and I purchased one of these first but it was still sitting in the UK when I spotted the unit from Japan - so I resold the Corsa Unit I had sitting in UK.
