350z Diff into S30?

[Neverdone]

I was running around gear ratio's and kept noticing that almost all the LSD R200's all have ratio's that are kinda high. 3.545 was the lowest I had found out of an Infiniti.

 

However, finally thinking, why not just look in newer Z cars, I found the 350z automatic has a diff with a 3.357 ratio and is a R200 VLSD like that of the Infiniti.

 

So that leads me to my question:

 

With the proper installation brackets to install a short nose R200 into a 240z, is there any reason as to why this differential will not work?

 

Also, has anyone done this swap before?

You can find a 3.30 iirc that fits the r200.

The R200 in the 350Z has a unique mounting setup. Its different from the other short nose R200s. You'll also have to work out the side shaft. Spline counts are the same (29) but the lengths of the shafts are different side to side and different from other R200 CV setups. You'll also have to swap the pinion flange.

Did a search on this - I'm putting the 06 350Z drivetrain in my 75 280Z. I have the donor car, so if the 350Z version R200 can be made to fit, I should do it. My stock diff has 250K miles on it, & whines like heck.

 

So, 13 years on, just looking for any pointers here on mount adaptation, Axle flange & diff casing attachment. (350Z diff) Pics off eBay, mine is still in the car

 

 

 

 

swap the rear covers?

 

 

I have installed 300ZXT axles with modded outer flanges in mine
