HR31 r200 longnose into 280z with r180

[intuitdriver]

Again I have exhausted the search option, google, skyline forums etc and I can't quite figure out if the HR31 skyline's r200 longnose 4.11 LSD is a straight swap into my 77 280z with a r180 diff. Anyone got any info?

Im concerned about mounting and axel issues. Thanks

Other than needing R200 half shafts and mustash bar, it should go right in.

You also need (for lack of a better explanation) the rear chapmen arm/ diff brace thing. This is the curved one instead of the straight one, it only makes getting to the fill plug easier. Not a necessity but a nicety.

 

 

It runs across the back center of the diff:

It runs across the back center of the diff:

That is only needed on 70 and early 71 240Zs. After mid 71 they moved the diff back and all of them got the curved link.

The parts list needed to bolt in a longnose R200 into a 240Z is as follows:

 

1. mustache bar from 280Z with R200

2. yoke (companion flange) from 280Z with R200

3. rear cover from 280Z or ZX with R200

4. side stub shafts from 280Z or ZX with R200 to bolt up to stock halfshafts

FOR EARLY 70-71 Z's only, you need 5 -7.

5. Longer 72-78 driveshaft

6. Curved transverse link that sits right behind the diff from 72-78 Z

7. Flip front diff mount around on crossmember

 

5-7 are necessary because the early Z's had the diff mounted forward, and swapping to the R200 moves the diff rearward. Obviously if you buy a diff from a 280Z with an R200, it has everything you need except the mustache bar. If you buy the 300ZX diff, then you need the above pieces.
