6 speed gear upgrade

**oblark** · Sunday 17th March 2013, 17:38

I brought a Ford focus ST225 from ebay during the week and stirbo collected and delivered to the southern dyno day.

Once getting back from changing Steve`s turbo on his 850R I bolted the box to my spare block.
All the bolt holes lined up and the standard 850 driveshafts fitted aswell just need to remake the linkage as it`s not the same as the 850 one.

M56H is 0.70:1, the Volvo M66 also has a 0.70:1. Whats the FDR on the Crocus box?

**p fandango** · Sunday 17th March 2013, 17:56

& according to HERE the Crocus is also 0.70:1 with a 4.0 FDR, exactly the same as 5th on the T-5

Glad it's fitted up O.K. mate.

2009, seems longer ago than that lol. My mistake about the 4.00 FDR, i was looking at the M66W (which does have the 0.65:1 on 6th)

Dont quote me on this but think someone told me a while ago later v70/s60 fitted with the six spees boxes linkage will fit the 850 shift assembly

Thanks for that, I`ll look into it

I'm pretty gutted now, I had a complete ST which had been vandal damaged, I wanted the 18s and seats, looked into the gearbox fitting and was told it wouldn't fit, scrapped the whole car
