FS: Z31T axle adapter flanges for S30 + R200. Slim design

[mtnickel 16]

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.

 

I've got a PDF of the instructions for install attached.

 

Sets are $195 USD shipped when paid with "friends/family" otherwise I get charged fees.

$220usd with jig rental (highly recommended). Plus you have to pay to ship jig back.

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.

Wish it filled the old stud holes

You could weld em shut if you want. To machine that would make them thicker and add a lot of machine time. For cosmetic reasons only.

Okay

Hello,

Are these adapter flanges still available?

[mtnickel 16]

Just sold last set, but I’m ordering a new batch. Ordered 12 sets, now all gone. 

[Old Man 10]

Thank you for the reply!  Can you please reach out to me when a set becomes available?

[fluidmotion 10]

[mtnickel 16]

@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

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.

  Thanks for sharing, really looks great!  Did you do the welding?
