I have a 79 mt n/a 280zx and I understand that it has a 3.36 rear diff gear ratio. Will a R200 from an 81-83 ZX be a bolt on? Or will I need to modify my car? I want the 3.9 ratio, for better acceleration of course!

'85 20SX turbos had 4.11:1 R200s. I would guess that other years close to that also had them but am only sure about '85. Open diff by the way.

Do you know how much of a difference there would be in acceleration between the 3.90 and 4.10 gears (like how many tenths of a second difference there might be in the 1/4 mile)? I know the 4.10 would be the best, but R200's with 3.90's are plentiful and I think I could find a good one for a low price.

I copy and pasted it into my browser's address box, and it worked just fine. Maybe try refreshing it?
