does my wrecked 280zx have an R200??

[e_racer1999]

i was under the impression that all 280zxs had R200s, but then i came across this table:

-------------------------------------------------

280ZX 79 MT,4 Spd,2 Seater (3.364) (R180)

280ZX 79 MT,5 Spd,2 Seater (3.364) (R180)

280ZX 79 All With Automatic(3.545) (R180)

280ZX 79 MT,4 Spd,4 Seater (3.364) (R200)

280ZX 79 MT,5 Spd,4 Seater (3.7) (R200)

280ZX-GL 79 (3.7) (R200)

-------------------------------------------------

^can this be correct?? i hope not, 'cause i have a 2-seater

btw, this table was sourced from http://www.kaynor.net/v8-240z/240z.htm , which is an AWESOME resource if you haven't checked it out yet

I checked my references and came up with the same numbers . You might think of pulling the rear plate and check the numbers on the ring gear. This will tell you for sure what you have.

Here is a picture of R180 and R200, and some basic R180 VS R200 diff info

hmmm.... thanks for the info.... so if i read that article right, the R180 might just be perfect for me, and hence there was no reason for me to flip out! now i feel dumm.... anyway, thanks!

As long as the diff is in good shape and the gear ratio you want , there is no reason to change . I know a couple of Z drivers with V-8 and they are running 180 and not having any problems. I made the switch only because of the gear ratio and a good buy on the parts. Gary

ya, i'm gonna use the r200 (3.70) temporarily until i get 4.11 gears for my r180.... unless of course i can afford the gears first!
