Sounds like Mike is the man and the go to for M66 conversion parts?
P80 Platform 6 speed discussion
A comparison of the 5 and 6 speed boxes based on 6000 RPM gear changes. The S60R runs the same ratios as the XR5 but with a slightly taller 3.77 final drive.
5th and 6th in the 6 speed are the same as 4th and 5th in the 5 speed so top end and highway cruising remain unchanged. The problem with the 5 speed is 2nd - 3rd is too big which the 6 speed rectified and keeps you more in the power and torque range across all gears.

Thanks for all the trouble your going to Michael
The M66 appears to hold the revs during each gear change much smoother as you say, producing a better curve.

Alot of people prefer 5 speed on a boosted engine. And 6 on NA.
Some m56 came with 3.7 and 3.5 also.
Are you installing an lsd while the box is out?

If you've had an 850 turbo on a track I'm sure you'd change your mind. Even a spirited drive through some twisty roads exposes the ratio problems.
I'll be fitting a gripper differential to mine but there are much cheaper LSD options. I won't be fitting the gripper before test fitting and driving it in my NA 20 valve.
Yea I have an 850r m59. I find the ratios great.
If you get a chance when you pop in the lsd could you please measure the width of the gears?
What's the part number of the rear mount you used?

I already have 2 of them on order....
hamsandwichWhat's the part number of the rear mount you used?
These are able to be used.

How much were they?
Will basically be $20k landed here. I bought boxes in the UK and had them shipped to be done rather than sending from here. One is getting a quaife diff and AWD while the other is FWD with a gripper. They are complete with shifter assembly and digital gear position displays.
That's really not too bad. ?
@VolvoMike i can’t wait for you to fit the FWD Quaife box to my 850r wagon. The boost will really match the ratios.

What's the build specs? Drag car? Tell me there's gonna be an 850 wagon at WTAC?
Would be a massive waste on a wagon @au_850r... The sequentials are destined for awesome sedans.

Sedans will never look as good. ?
Correct... sedans look better!! and go faster.
