zx r180 to r200 swap

[Guest JSutter85]

I am going to swap out my r180(81 5spd ZX) for a r200(82 AUTO ZX). I am going to go ahead and swap out the entire suspention because of the CV shafts and the AUTO car has larger brake pads maybe larger rotors(?)

 

Question is :

Will I need another driveshaft or will my factory one work or the Auto cars one work?

I could be wrong but hey, no replys -- its worth a shot.

 

I belive both the R180 and R200 from the 280zx's were both long nose and should both fit without any changes.

 

I could be wrong, im ore interested in changing the R200 with a 87 z31 lsd R200, and I belive their the same size as well.

 

Hope this helps, and that im right.

 

Just read this:

"Cars with automatic transmissions had the R-180 diffs, All manuals and turbos had R-200s."

Did the reverse swap and everything fit. 5 spd from 81 n/a into 81zxt. Drive shafts and output shafts were different so I wound up pulling a R180 from a 81 2+2 w/cv shafts and putting it in the 81zxt. Drive shafts on turbos are fat little guys like a z31. Drive shaft on n/a is skinny. I could have had the drive shaft cut and weld on the parts from the two units that worked but the R180 at the junkyard was the cheaper solution moneywise but not timewise. So short answer yes you better check your driveshaft before you start the swap. The input flange to the Rxxx is changeablae with a large wrench or impact tool but can't always find one that fits the driveshaft. The skinny drive shaft uses M8 bolts and the fat guy uses M10 (might be M6 and M8 can't remember). One set of bolts has a half moon head the other is conventional. One input flange is round and the other square.
