6 speed gear upgrade

Found this on a ford forum about m66 gear ratio`s

i'm not convinced he's got his numbers right, the Volvo ratios he's quoting are for the M66W yet with the FDR of the M66. He also says the F*rd box has 4.00 FDR

[p fandango]

M66 (S60R AWD)
FDR = 3.77:1
1st = 3.38:1
2nd = 2.05:1
3rd = 1.43:1
4th = 1.08:1
5th = 0.86:1
6th = 0.70:1
top speed = 182mph

M66W (T-5)
FDR = 4.00:1
1st = 3.39:1
2nd = 1.91:1
3rd = 1.27:1
4th = 0.95:1
5th = 0.78:1
6th = 0.65:1
top speed = 185mph

M66D (D-5)
FDR = 4.00:1
1st = 3.39:1
2nd = 1.91:1
3rd = 1.19:1
4th = 0.84:1
5th = 0.65:1
6th = 0.54:1
top speed = 223mph

I have an M66 T5 fitted and working with mine now, Tim Williams did it all for me but he did have to make a custom linkage to make it work correctly!

Should have got a m66d box 223mph

Should have got a m66d box 223mph

The TDi 5cog I've got does 203mph@6500rpm

I bet the d5 box would be good for mpg, but i also guess it would be too long for a t5.
I take it the M66w and M66D are the same box just different ratios, and the d5 box would fit?

what cars were the M66w fitted to?

S60 t-5

I love the 6 speed box in my v50 t5 same as the focus 70 mph = 2400 rpm so better mpg, plus when you have had 6 gears going back to a 5 is like going back to a 4 your always looking for the extra gear that's not there!

[oblark]

As the sun was shining I set the spare sub frame, bolted on the engine block,head and turbo then the 6 speed gearbox.

Will have make a custom rear gearbox mount as they isn`t much space between the turbo,gearbox and the rubber mount




Apart from the rear mount the gearbox fits

[claymore]

What's different about the rear mount?

[oblark]

The M56 will not fit on the M66 box, and the M66 mount will not fit under the turbo

How are you going to get around the reverse gate problem?

What reverse gate problem ?

[Wobbly Dave]

To engage the reverse gear (up & far left) on the 6 speed manual you have to push the lever down before you can get it. It sits adjacent to 1st.
That gate protection is on the stick/selector AFAIK. Without it I am fairly sure you can select reverse whilst moving forward (unlikely) or more likely select reverse, when setting off.

On the box I`ve got reverse is over by 5th and 6th

1 3 5
2 4 6 R

[Wobbly Dave]

Must be different to the one on my diesel s40 then. I thought they were all

R 1 3 5
_ 2 4 6

not that I was trying to throw a spanner in the works, just more of a heads up.

[stribo]

The R has the same layout as Rob's, i.e. with reverse next to 6th

[lance]

Yeah the 2.0d and t5 use a different pattern

[oblark]

Made the most of the weather on Saturday and knocked up the rear engine/gearbox mount




The next job will be to make a new downpipe
