After seeing dat383s Gemini rack and pinion set up (bloody nice) I thought I'd do a search for info on rack and pinion steering setups for 1200s and cant find anything...
SO:
I really want to run a rack and pinion setup in my 1200 for a few reasons;
for improved steering feel and better turn ratio.
more space in the engine bay, relocating the rack and cleaning up the look of the engine bay (personally I think the old box looks real ugly)
I know the standard 1200 setup is pretty good but if there is a easy(ish) option I'll do it (I don't expect it to be easy but I don't think its worth $1000s and extensive engineering). Is there any other setups people have used? I think a toyota starlet or AE86 rack would be pretty close...
If possible I'd like to keep the rack behind (on the firewall side) the cross member as my sump is winged on the front and it will save me swapping the struts over.
Any help would be appreciated.
Cheers
well its clean and shiney, but have a closer look at the width of the rack (to its pivots) and where the control arm pivots are. remember dat383 is a dedicated drag car - bump steer isn't a huge issue for a car designed to drive straight ahead.
I agree that a quicker steering ratio would be a big improvement, particularly for high powered 1200's. Its so much easier punting around late model turbo cars like the GTR and Supra at 10/10ths on the track than the 1200 because of their beautiful quick steering - corrections are quicker and more accurate. The Datsun needs alot more respect solely because of the slow steering response. Not so much of an issue for under 2L cars - you have alot more time to make corrections.
its not impossible, but its a fair old engineering exercise to get it right, and will be difficult to find a rack the right length. I was looking at this for my 1200 as soon as I got it (about a year ago). All the engineers I spoke - one who have been building space frame cars for years - told me to forget it. packaging a rack into a car not designed for one with limited space is not an easy thing to get right. if you have an A series you will have alot more room to play with, but then my opinion is you don't need a rack with those power levels. that's been my experience anyway.
