I have a 3.9 H145 Diff which I need to change the ratio in. Does anyone have a Higher ratio centre for a H145 or even a H150 3.35 ratio would be good and i can use a spacer.

Any Ideas or sugestions?

3.39:1? Do the ratios go that high?

I wouldn't mind a 3.5:1 for a BW68.

3.50 for a BW68...?

the only ratios I know for the BW68 are

3.889
4.10
4.30

the last two are not available in a aussie spec 120Y or datsun

they are KE30 BW68 ratios...

I want a solution to this as well, keeping original on 12" rims its badly undergeared. I thnk its because the 1000's were built at the nissan truck factory and truck type ratios went in.

its because they were only 1000cc... they needed a lower ratio to make up for the lack of torque from the engine.

The H165 was available in a 3.7 to 1 ratio, but can't be sure about a 3.54 to 1. Certainly not in Australia for that one anyway.

Well I have 3.7:1 for my BW68 and I have heard of 3.5:1 years ago. I don't know what car they come from. Possibly a 2.6 sigma or something like that.
