Z car gear ratio choices.... who runs what gears?

[datrod]

ok. That sounds like the engine the older tC came with

 

I don't know what is in my wifes 2008 XB but it runs pretty good. :lol:

I prefer the 38mpg xA ;)

[SublimeDatsun610]

that xA works for those who don't have a bunch of teenagers. back to topic. i should be looking for this 3.90 diff from what year of cars? trans combos?

[datzenmike]

R-180 ...

 

Maxima sedan manual transmission.... 3.90

'84-'86 CA 200sx................................. 4.11

'83'-86 720 4X4.................................... 4.11

'80-'82 720 4x4.................................... 4.375

If you upgrade to an R200

 

3.9 R200

 

1981-83 non-turbo 5-speed 280ZX

[datzenmike]

'87 and up 200sx with VG motor, R-200 X 3.90

[SublimeDatsun610]

it looks like there are some options out there

[SHADY280]

sounds like the z may need a tune up as well. maybe tune the carbs and set timing. find a early 5 spd they have really good accel ratios

[SublimeDatsun610]

well, i just got finished replacing the clutch and stuffing a 5 spd in about an hour ago. haven't lower it from the jack stands for the maiden voyage yet. next is the rear diff. i know the Z is running a bit fat.

[datzenmike]

SHADY I believe the very first B type 4 speed used had a very low first gear and wide spread ratios. The z 4 speeds from Dec '74 on were the same 1 2 3 ratios as the 5 speeds up till the zx, and would be considered a medium close ratio tranny. The zx 5 speeds were even closer ratio.

[SHADY280]

yeah mike, i have a 77/78 year z 5spd. its ratios are very much more noticeable compared to my 82 trans thats in there right now. i also have my trucks 4 speed, it should have stump puller ratios!
