Does anyone know if an MT75 box will fit into the transmissin tunnel of an S1 without having to modify the chassis or is it too wide / deep?

It appears to be shorter and have a more easily adjusted gear linkage which might allow the gear lever to come up in the right place ( vertically ) and it as apparantly stronger tha pn the type 9 in there now ( but others say it isn't ).

I don't mind changing / making new gearbox mountings but do not want to make any changes to the chassis tubes themselves. Does anyone have any exoerience / advice on this?

Thanks,
Dave

I'm pretty sure Magpies has fitted the MT75 box in his car fairly recently.

The 2WD version fits fine. Same mounts and bell housing. You will need a modified prop. And as you already know, the gear linkage will need a little work.
As stated above, Mike ((magpies) has a lot of experience with this.

Or you can modify the housing to move the lever forward and remove the linkage.

Yes the box fits nicely - I'll post some piccies when I get home if Virgin have fixed the broadband (whole area having problems for two days now)

I used a 2.0 rwd rear attached to the v6 front part of the 'box (a local gearbox company built this for me) the spider output connector changed to a flange and a prop company made a new unit to connect to the diff. I modified the gear linkage so that the stick comes srtaight up into the cockpit - the radio / dash stops it from being located at the optimum position. Also the box is a cable type and needs to be converted to hydraulic - the easy route would be for an internal concentric slave, but I chose the 'not so easy' option of fitting the original external slave. The box is stronger than the Type 9 but that should be ok if you have a standard V6 and the box is in good condition. If I did it again (which I won't) I would fit a TranX or Quaife kit into the Type 9 rather than fitting an MT75 - that way you can chhose the ratios too.

Would seem a lot easier than the work magpies listed above.

Hi Mick,

Some photos of your set up would be good - especially the clutch actuation set up.

I did consider a Tranex or Quiafe build into the type 9 casing until I saw the price. BGH geartech do similar builds for the type 9 at a more resasonable price but it's still very costly.
The engine is a 2.9 cosworth 24 valve.

I posted something re the dash mounted warning lights & wiring you asked about - Phillpott has also added his usual helpful hints and tips.

Cheers,
Dave
