Nizzan Posted August 20, 2008 Share Posted August 20, 2008 Whats also nice about that is that you now can get new cv axles that arent "rebuilt" and arent 20 some years old. Thats what I was thinking too, I previously had an open r200 3.90, and had to get rebuild axles for that. Link to comment Share on other sites More sharing options...
JMortensen Posted December 11, 2008 Share Posted December 11, 2008 How about sticking this thread, admins? Seems like we have people who keep asking about subaru lsds who can't seem to find it. Link to comment Share on other sites More sharing options...
logr Posted December 11, 2008 Share Posted December 11, 2008 Don't know why I couldn't find it when I was looking for it before but a sticky would be nice as there is a new thread asking about it now. Thanks, Jon Link to comment Share on other sites More sharing options...

Wedge Posted April 18, 2010 Share Posted April 18, 2010 Ok if i get this right to put the STI diff in a 280Z I need the Betamotorsports adapter and a R180 mustache bar from a 240z then im set ? Link to comment Share on other sites More sharing options...

Correct! Although I haven't heard of anybody needing to change the mustache bar. The R180's are both the same on the outside and it justs bolts in. See this link on how it's been done. You may want to skip to the end to see the finished results. http://forums.hybrid...662#entry908662 Link to comment Share on other sites More sharing options...
Neverdone Posted January 21, 2011 Share Posted January 21, 2011 I had a question, and this might be mindless nonsense that I would like to have happen, even though it's impossible. Anyway, I get that the main problem with the Subaru R180 is adapting it to fit our companion flanges and wheel ends because of the odd outside CV that Subaru's come with. Well, as to run this setup custom axles have to be made anyway, would it be possible to attach an inner Q45 CV joint to the outside end of the axle and then use the methods we've been using for years to attach those to our companion flanges? It seems like if the spline count is different it wouldn't matter because you'd just have whatever shop make the ends have different spline counts when cutting them. However is the width of the axle going to put the stops on this crazy idea, anyone have any idea? Link to comment Share on other sites More sharing options...

Neverdone Posted January 21, 2011 Share Posted January 21, 2011 Well, if anyone knows what the width of a stock Infiniti Q45 and Subaru STI, or even regular WRX axle is, I think that would answer my question. If they are the same, or even similar, imagine how awesome that would be! Link to comment Share on other sites More sharing options...

If they are the same, or even similar, imagine how awesome that would be! The WRX axle won't fit the STi differential. You need an STi axle. Read these two threads where we did fit the STi LSD into the 240z. http://forums.hybrid...u-wrx-sti-r180/ http://forums.hybrid...__1#entry745031 Link to comment Share on other sites More sharing options...
Neverdone Posted January 24, 2011 Share Posted January 24, 2011 Thanks for the links, but I couldn't really find any dimensions on the axle widths. To me it really seems like as long as you have a decently gradual neck down to the smaller diameter end, it shouldn't put too much of a stress concentration on the axle vs. just narrowing it straight into the bar on a lathe. I mean, if anyone has an STI or Q45, or is just running either of those cars diffs, if you could get under your cars with a pair of calipers it would help me out a lot.

I mean, if anyone has an STI or Q45, or is just running either of those cars diffs, if you could get under your cars with a pair of calipers it would help me out a lot. You need a special machine to make the splines, that's not a machine most machine shops will have. The last step in making the splined axle is to harden it. Once it's hardened, your done and you won't be able to turn it again. You will need to have new axles made with the appropriate splines. I'm pretty sure the CV Joints are removable from a splined axle shaft. If you can find a CV that mates up to the stub axle of the Datsun, then you could have a new axle shaft made and use the Subaru CV that fits the output side of the LSD. John took the route of making a new output shaft and using the stock 240Z axles. Less work and for the purpose of club racing with "stock" rules, the car is still stock. There is a shop that makes CV axles to bolt into the 240Z and will fit Johns output shaft. Why don't you buy the used Q45 part and see if it even fits like you want it to. I bought a few different parts thinking they might mate up to find they didn't. I didn't spend a lot learning what did not fit. The WRX axle does not fit the STi LSD. I know cause I bought one.

nissun1 Posted April 27, 2011 Share Posted April 27, 2011 ive also been meaning to make this same setup all i need to kno is what year did he use for the 280z axles? the same 27spline with the cv joint? Link to comment Share on other sites More sharing options...

By "he", I assume you mean the OP. I do not know what "he" did, but I do know what I did. I bought a set of new output shafts from John Coffey.

See this thread for all the details. http://forums.hybrid...180-side-axles/ I looked into john coffey's stub axles but i prefer to go with using the custom shaft with the 280z cv joints and stub axle hub. Knowing the year would help i think it would be 75-78? By he i meant Nizzan. If i were to spend that much on stub axles i might as well go with wolf creeks porsche cv upgrade:blink: Link to comment Share on other sites More sharing options...
