mtnickel 17 Posted May 28, 2018 Share Posted May 28, 2018 (edited) Update June 2021 - sold out. Sorry Had a post about the design process and checking of clearance in the Drivetrain section. Now here's the sale post of the adapters I've made several sets of. Quick Description: Z31T weld on adapter Flanges to fit Z31T CV axles into S30 chassis with the use of an R200. Long Description: They weld onto the outboard axle flange to provide a bolt pattern that will fit Z31 Turbo axles. The axles are NLA but you can find them on forums, craigslist, car-part.com, ebay, etc. They are a very strong axle. It is for an R200 diff, not stock R180. Rockauto has recently has some new style axles. The CV type is tripod which is a little weaker and the axle shaft diameter is fair bit smaller. no idea how much power they will support. 1) They are weld on style. They must be welded by someone with a little experience since you're welding to the stock cast flange. They also must be bolted down if you want the flange to remain flat. They also must be centered into the square relief. The Square flange IS NOT concentric to the rotational axis and it must be shimmed and positioned correctly so that there is minimal runout. *** A JIG is now available to rent that both locates center and keeps the parts flat during the welding process. $20 + shipping to the next user. 2) They require grinding the stub axle nut and shaft between 1/16-1/8" depending on if its 240 or 280 style. Basically enough so that the flange is flat. 3) They still require flipping the cages inside the CV. I've measured that on the Driverside it would be fine (only 2.5mm of clearance) without, but I'd do it anyways. Passenger side is tighter and needs it. 4). Material is mild steel. Paint or powdercoat (if you remove the stock flange to weld) at your own will to prevent corrosion. A jig is available now to center the stock flange to the new flange and hold it during welding. Sets are $200 USD shipped when paid with "friends/family" otherwise I get charged fees. I now just include a jig with all sets shipped (unless you prefer not to have it). It just saves you and/or the welder a lot of leg work to prep for welding. But you need to ship the jig to the next user. This is a link to more info and installation process. https://www.dropbox.com/s/23dj8il5rru20i3/Z31 Turbo CV axle ConversionV4.pdf?dl=0 Edited June 23, 2021 by mtnickel Updated price and doc Quote Link to post Share on other sites
mtnickel 17 Posted May 28, 2018 Author Share Posted May 28, 2018 I also built a jig to help in welding. It locates the flange on the stock locating ring on your stock companion flange. I can rent it out for shipping costs and security deposit and such, but if you know how to shim something and use a Dial indicator to check runout, may not need it.

To machine that would make them thicker and add a lot of machine time. For cosmetic reasons only. Quote Link to post Share on other sites

studioti 11 Posted March 13, 2019 Share Posted March 13, 2019 (edited) @mtnickel Would like to purchase a set of these adapter plates, plus rental of the jig and PDF instructions to get perfectly centered. How do I go about paying you ? One more thing... you mention "flipping the cages" to make the z31t axles shorter....where can I find more info on that so when I rebuilt my axles...I can do that mod. Thanks James Edited March 13, 2019 by studioti added info Quote Link to post Share on other sites

rbzed25 1 Posted July 28, 2019 Share Posted July 28, 2019 Just finished welding the adapters together, figured I'd give my review. Turned out to be relatively straight forward and simple. Only extra work required was some grinding of the inner edges so my 280z adapter would seat correctly. Definitely get the welding jig if you don't have access to a mill or lathe. 1 Quote Link to post Share on other sites
