What Gearboxs Fit

(1/5) > >>

Lurch:
It seams people are getting a bit confused so I've copy & pasted from another post:

5 Speed Gearbox's from:
280ZX
240/260Z (775mm long)
240K Skyline
C210 Skyline
R31 Skyline (Bellhouseing needs changing)
S13/S14 Silvia/180SX SR20 & CA18 engine (Bellhouseing needs changing)
S1/2 Bluebird (S3/CA20 box's; Bellhouseing needs changing)
200B
240/260/280C sedans

These all fit, BUT they have different mounts & different internal ratio's & gear sizes.
There may be a bit of mucking about getting them to fit.

The early 240Z box is called a 71A (has the output flange at the back of the box).
Late model 240Z & 260Z is called a 71B box,
And the R31 skyline, R32 GTST Skyline & S13 (SR & CA) boxes are all called 71C's.
They are all just evolutions of the same box.


The only ones that WON'T be suitable are:
R30 Skyline
Stanza SSS
Any of the Datsun L4 4-speed boxes.
These gearbox's are around 660mm in length.

These are 'short' boxes & are not long enough.

The box's from the R33 Skyline & the 300ZX (Z32) will fit but require bellhousing modifications.

When fitting a 260Z gearbox into a 240Z, normally the 260Z shifter will hit the front edge of the centre console (due to the fact the 260Z box has a shorter extension housing.
This is how you get the 260Z shifter to come up in the correct position - heat it up with the Oxy torch & put a few bends in it!



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

260Z Gearbox Ratios are:

1st:  2.906
2nd: 1.902
3rd:  1.311
4th:  1:1
5th:  0.864
Rev: 3.382

(Open for correction at this time!)

awesome info there lurch, By chance, if anyone knows (or can measure) what is the lengths of the boxes? from bellhousing flange to output shaft flange?

i have a spare box that i suspect may be a short one, but dont know.
I only knew it was from a L series engine of some description.

I guess to add to it, if anyone does have actual gearbox ratios, it would be good to keep all in one thread, would make a good resource for selecting approriate ratios to suit particular applications.

Updated.

NZeder:
There is a rare factory L6 71C box I know I have one :) it is from a Nissan Laurel C32 fitted with a LD28 so I have not found out the ratio's yet but it is a L6 71C from the factory ie no mods to the bellhousing required.

The partnumber for the front bellhousing on this box is 32101-49L07 and there is an alternative part-number listed as 32101-49L80

Well I'll be buggered ugly!
Thanks Mike :)
