SmoknR6 Posted December 20, 2004 Share Posted December 20, 2004 Hey, I have been doing a lot of searching and keep finding different results. I have a 74 260Z, and am looking to do an R200 Swap. Some people say that if I get the R200 out of a ZX I need half shafts from an R200 out of a Z, and others are saying that i dont. Can someone clarify this?

MaTTSuN Posted December 21, 2004 Share Posted December 21, 2004 you need a new mustach bar for sure, i welded up a R180 but when i went 2 put it in the bolt holes didnt line up. You prob need the half shafts from the R200 because the diff is a little wider i think the R180 shafts are longer. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 21, 2004 Share Posted December 21, 2004 Take a look here: http://www.betamotorsports.com/benchracing/index.html and click on R200 handling issues. If you have an early 260 I think you'd have this problem, if you have the later body style 260 then I think you're OK. I'm one of the people who made the argument that the R200 shafts were shorter, and now I think I was wrong. I've measured every shaft I have, and come up with the same measurements John has on his website there. Quote Link to comment Share on other sites More sharing options...
JFryer Posted December 23, 2004 Share Posted December 23, 2004 Yes you will need the half-shafts and mustach bar from a 280Z for this conversion. 260 shafts are a flange and yolk type vs flange on both ends for the 280. Also read John C's web site after my conversion so I went out to the garage removed my springs and measured the half-shaft and found that I still had 1/4 inch of travel left in the half shaft at the point of max shaft compression. NOTE this was a static measurement on my early 260 with coilovers and poly bushings. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 23, 2004 Share Posted December 23, 2004 260's are a yoke type? Whaa??? I thought every Datsun halfshaft from 240Z to 280ZX was the same, until you get into the CV shafts, which are yoke on one end and flange on the other. Have I just never seen a 260 shaft???

zcarnut Posted December 23, 2004 Share Posted December 23, 2004 Jon; The 260Z axles were the U-joint style that use a single bolt to secure them to the diff. Nissan continued to use this method of attachment to the diff on all the later R180 differentials (ZX and 810's only as all the 280Z’s had a R200). The 240Z R180 axles were also U-joint but as JFryer pointed, they have a flange on both ends. However, this is the same axle that all the later R200 used, as you mentioned the length (and even the Nissan part number) is the same . Unfortunately, most people refer to the different axles as the “R180 axle” and the “R200" axle. But this is not exactly correct. Clear as mud?

JMortensen Posted December 23, 2004 Share Posted December 23, 2004 So all the HALFSHAFTS are the same. The flanges that slide into the diff are different, but they all bolt up to the halfshafts just fine. That's what I thought, but every once in a while you find out what you thought was wrong...

I will call this separate piece the diff output flange. The 260Z and later R180 axles do not use this separate piece or output flange. The diff end of the axle slides just into the diff where it is secured with a single bolt. It’s like Nissan did away with this diff output flange on the later R180's and used the 260Z style axles. My guess is that it made assembly at the factory quicker, as the line worker would only have to tighten one bolt (per side) instead of four bolts (per side). A picture is worth a thousand words, Jon, so please look at the FSM’s. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 23, 2004 Share Posted December 23, 2004 Hmmm... I don't have a FSM. Guess I'll have to look under a Max or an auto ZX one day... Thanks for trying Steve. Quote Link to comment Share on other sites More sharing options...
datsunlover Posted December 24, 2004 Share Posted December 24, 2004 So.. from 75 280 to 83 ZX have the same shafts then.. Cause I have a 75, and am swaping in a better (ratio and overall condition) r200 from an 81 zx.. I have had to change the driveshaft yoke (difrent bolt hole circle) to use my 280z driveshaft, but the axles apear (to me) to be identical between both..

zcarnut Posted December 24, 2004 Share Posted December 24, 2004 Here's a pic from a 280ZX FSM: Notice that the the only difference between the axles is the diff side flange. Since this flange is secured by the inboard U-joint, it is considered part of the axle. The diff output flange (used on the R200) that slides into the diff is not shown in the pic as it is considered part of the differential.

SmoknR6 Posted December 26, 2004 Author Share Posted December 26, 2004 I think im just an idiot, cause im still confused..Do i need to get the entire rear end out of a Z, or will the rear end out of a ZX work just fine. Mine is a 74, so its the earlier style. Quote Link to comment Share on other sites More sharing options...
skipzoomie Posted December 26, 2004 Share Posted December 26, 2004 The shalfs from the turbo models had larger flanges. Other than that they were the same from 75 to 83. Quote Link to comment Share on other sites More sharing options...
