6 speed manual gear ratios

[Nataphen]

old thread dig,

The M60, offered in the Zafira Tourer and the Astra K have the most stacked gear ratios of all M32's, with the lowest *numerical* final gear:

4.27
2.53
1.6
1.15
0.94
0.81
3.348 final gear

The total final gearing (6th x final drive) of the MZ4 is 2.24, the MZ0 is 2.93 (ouch), and a MZ4 6th gear swapped into a M60 would be 2.06.

For a 25" tall tire that means 6th gear would drop 200 rpm at 75 mph compared to stock. Where the MZ0 raises rpm by 700 at 75 mph.

Though still not as ideal gearing as the MZ0, if a 6th gear swap is possible, this setup would offer better acceleration in 1st-5th and better highway mpg than a stock sonic opcorn: + 1st would be usable unlike the RS gearing

Does anyone know if a sixth gear swap is possible? I like this idea.

Found this. Helpful.

Deadish thread I know....but is it still the mz4 that is utilized in the sonic 1.4t?
I'm thinking about an MZ0 to help alleviate the 1st to 2nd gear grind and just general difficulty. The MZ0 appears far more linear....I wonder if a guy could swap 6th into an MZ0 to maintain the appealing highway final drive?

The MZ4 is the only transmission available in the Sonic 1.4 since the refresh. I’d also like to know the answer to your question here. This would be a great swap.
