280ZX Box in a 260Z

[oldmates260z]

Anyone know the differences? The gear change on my original 74 260Z is not great however when my son had his 280ZX it seemed a nicer change.

 

Is a 280 box a better option?

The 260 box is meant to have great ratios for better acceleration when coupled with the right gearing in your diff. I have a 74 260 and my gearbox had worn synchro's. Changed it for a 280 box and could'nt notice that much of a difference, really happy with the 280 box.

I thought the gear mechanism was different on the later boxes. The early Datsun boxes have a bad tendance to get worn and be very sloppy. I thought the later boxes (like the Bluebird ones) had a better mechanism. Was wondering if the 280ZX had the same gear leaver set up.

 

My thing does not like going into fifth.

I think the only major difference is in the 1st gear ratios, 260 has a 2.90 and the 280ZX has a 3.20. So if your happy with  a shorter first, lovely! Also depends what diff ratio you are running...

basically same box, some have diff ratios, some dont.

later 280zx's have new shifter bearings and mostlikely less use overall, main probs with shifter are external of the bok, ie gearleaver bush and clevis pin, but the can have bad syncros, shifter/selector collars and shifter linkage dentents which click and hold the gear some what, but the worn synchros on 2nd are most common, can be sort of fixed just by flipping the collar around so 1st has bad sync, but how often should you really downchange to 1st,
