280zx, S130 sub-frame in 260z, S30

[Dodger]

Hey guys, this is my first post.  I tried to search it but I didn't find what I was looking for so if its been discussed before don't flame me to much, thanks.

 

So, I found a rear sub-frame out of a 280zx with the R200 and the 390 gear ratio (which to the best of my knowledge is the lowest regularly available gear ratio to find).  

 

I know I can swap the R200 easily but my question is, can the whole sub-frame replace the 260's sub-frame?

 

I am wondering this because the 280zx has rear disks and I thought this might upgrade two assemblies at once if it was doable.  

 

I know, everything is possible with enough money but mostly I'm asking if it will bolt up (which I figure it wont), and if not, can it be made to relatively simply.

 

Thank yall

No the zx subframe won't just bolt in.

 

You can swap over the rear diff easier if you have a late model 260. I think the early model 260 requires the late model mustache bar.Swap over the rear disc rotors and calipers with early maxima rear caliper brackets.

You may have to research how to make the e-brake cables work.

Nice.  Mines an early so I figured I would need the other bar so that's no big deal.

 

I'll look up the the break conversion.  You wouldn't happen to have a link to a thread about it would you?

 

Thanks for the reply Dexter

Why would you want S130 suspension in an S30? It seems the S130 crowd struggles to make the the semi trailing arm work in racing applications. I did find the rear suspension in my ZX to be a happy going sideways. My S30 when it had an open diff was very unpredictable and challenging for sideways hoonery where the ZX would rarely only break traction at one wheel, do to the dynamic toe change I believe. That is little reason to go to the trouble of swapping in semi-trailing arm suspension though. 

 

Your rear assembly has undesirable U joint axles as well, so no upgrade in that department. 

 

If you want to punish yourself with a subframe/suspension swap, I'd look at something with more benefits. The S13/S14/Skyline multilink has be done, but many members will agree it's just not worth the trouble when the stock setup can be made to function pretty well.
