nsr500 Posted June 21, 2008 Report Share Posted June 21, 2008 :lol: Considering putting a Rack in it ( 1200) and putting up forward of the wheels. Is there a commonly used Rack-n-Pinion for these? Quote Link to comment
Icehouse Posted June 22, 2008 Report Share Posted June 22, 2008 the biggest problem is finding a rack that isn't to wide. The narrowest one I could find is still to wide for a dime, I used it anyways though :) the next setup I build I'm going to order a custom rack. Remember if you are putting the rack in front of the center line of the wheels you can't use a rack out of a car that has the rack behind the centerline or the wheels will turn the oposite way there suposed to.

Burabuda Posted June 23, 2008 Report Share Posted June 23, 2008 the biggest initial problem is finding a rack that isn't too wide kp61 is used in corolla 1200's, so you might want to give that a try however, be sure to consider the tradeoff: clearance for you downpipe, but binding in steering due to extreme u-joint angles Quote Link to comment
nsr500 Posted June 24, 2008 Author Report Share Posted June 24, 2008 The more I think about it, the more work it's going to be. I was just thinking I could put in a Rack and get that drag link out of the way of the oil pan. Guess I could always go old school and let it pass through the pan.? It's also the EZest to do. Hole , hole, tube and weld. Just one more step when pulling the motor. Quote Link to comment
ggzilla Posted June 24, 2008 Report Share Posted June 24, 2008 It's just three steps: 1. Cut rack ends, shorten, reweld 2. Weld tabs to crossmember, bolt rack to tabs 3. connect steering column. Use B210 or B310 column with flexible adapter. This is what drag racers do. Not recommended for street, as a certified engineer didn't create the calculations Quote Link to comment
DRIVEN Posted June 24, 2008 Report Share Posted June 24, 2008 Have you checked into a sandrail rack? Many input from center but not all. They are cheap (start at @$60), compact and as universal as it gets. Check sources like Latest Rage or other offroad suppliers. If you find a good fit, OEM or otherwise, let us know. I wanna do mine. Good luck.:thumbup: Quote Link to comment
nsr500 Posted June 24, 2008 Author Report Share Posted June 24, 2008 Yea I did see the buggy rack. It's really short ( good) but the splined part ya hook your st shaft to, it comes out right in the senter and straight, no angle on it. If it just had some angle pionting to the drivers side, it would work. If I did it, it would have to be mounted just forward of the stock cross member, may be 6-8". It was just a thought, putting a rack in. It's very ez to put one in and make it go straight down the track, completly different trying to make it turn nice and work well on the street. I use to have one out of a Wintson West car, all Alum and 1.5 turns to lock, and you could change the gear in it. Gone now. There is some scince invaled in getting the right set up so one wheel turns more than the other, can't remember what they call that right now. Quote Link to comment
ggzilla Posted June 25, 2008 Report Share Posted June 25, 2008 Just use a '83-'86 Nissan Sentra rack ? Quote Link to comment
thisismatt Posted June 25, 2008 Report Share Posted June 25, 2008 VW rabbit rack in an RX7...looks pretty narrow: http://www.rx7club.com/attachment.php?attachmentid=293602&d=1209343199 Quote Link to comment
thisismatt Posted June 27, 2008 Report Share Posted June 27, 2008 The rabbit rack is 52.5CM wide before tie rod ends or anything else are mounted to it. How wide is an MR2 rack? Quote Link to comment
BJW's FiveTen's Posted September 7, 2009 Report Share Posted September 7, 2009 Im seeing if a fiat x19 rack will work, or what about an mg midget, morris minor , both narrow, I have both will let you know what works best. Quote Link to comment
Jesse C. Posted September 9, 2009 Report Share Posted September 9, 2009 Ford Pinto steering racks are by far the most popular to use in most conversions and there are a ton of aftermarket ones based on this unit so finding custome parts should not be hard. Flaming River, Speedway, Jegs, Summit and some local parts stores carry them in stock at decent prices. Quote Link to comment
datzenmike Posted September 9, 2009 Report Share Posted September 9, 2009 The width of the r&p tube to where the side rods attach must be the same as the distance between the two lower control arm mounting points. If unequal lengths the steering will be affected when going over bumps. Quote Link to comment
ichorid Posted September 9, 2009 Report Share Posted September 9, 2009 when you have R&P and you're on a road with not so great of a surface. Dont you get bouncy steering problems? Quote Link to comment
BJW's FiveTen's Posted September 10, 2009 Report Share Posted September 10, 2009 You can build spacers that thread in where the inner tie rod would go. to correct for any difference in where the pivot/inner tie rod mount, I have been using the stock steering p/u(end of drag link) points as reference for now, I think the bump steer issue is a easy one to overcome.

Z-train Posted September 10, 2009 Report Share Posted September 10, 2009 I was looking at doing a rack conversion on my 620.What i found out is that NO off-the-shelf rack will work.The 620 is just too narrow.Also,there is a critical area with regards to rack width and it is called"Bump steer".If this is not addressed in the design,it can get you killed...easily. After all that is said,a custom rack can be fabbed but it will be $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.:eek: Quote Link to comment
Jester Posted September 11, 2009 Report Share Posted September 11, 2009 Im seeing if a fiat x19 rack will work, or what about an mg midget, morris minor , both narrow, I have both will let you know what works best. Any answers on this yet? Quote Link to comment
Jester Posted December 17, 2010 Report Share Posted December 17, 2010 OK guys. I was measuring a rack and pinion on a Fiat X19 today. The overall dimension was 42". The distance between the knuckles (if you want to call em that) is 19 1/2". PERFECT for a dime!!!! You would have to either flip your X member or build a custom mount for it though. Would be awesome for a KA setup. Quote Link to comment
DISLEXICDIME Posted December 18, 2010 Report Share Posted December 18, 2010 I think brain used a Opel rck Quote Link to comment
datzenmike Posted December 18, 2010 Report Share Posted December 18, 2010 On each side of the rack where the tie rods hinge, should be the same distance apart as the mounting points for the 510's lower control arms. Or the distance between the 510's pitman arm to idler arm. (the LCA would be best for geometry purposes) The larger the difference between the rack and the stock the bigger the effects of bump steer.
