I've noticed the 5speed ford boxes creeping up in value £400+ on ebay :-0

To clarify, it doesn't need the gasket but it does require sealant around the selector shaft O-ring:

Julian, 

Also think about the 5 speed with SPC rocket ratios. Long 1st and 2nd and shorter 5th. You're welcome to pop over to me in Heathfield for a ride.

There's nothing much wrong with the standard ratios. Yes, a higher first gear and a lower fifth are handy, but the standard ratios work just fine most of the time. This thread makes it sound like you've got to have custom ratios in order to use a Type 9.

If the six speed comes with a different diff, that might be an issue, but if you've got a non-LSD diff it's probably easier to change the diff and fit a standard gearbox than it is to try to match the box ratios to the current diff.

Roger,

Nothing wrong with standard ratios, after all, my 7 managed 86k miles on the standard T9 (Sprinting & touring) just fancied a change with more emphasis on the sprinting, although I've still toured with the SPC gearset. I find driving it a lot more enjoyable though with closer ratio gears. One man's meat.........

I had the 5 speed originally and fitted a 6 speed and 3.6 diff(1.6 K supersport). I really like the fact the 6sp keeps the engine on the boil and makes the drive quite involving though I can see a point where I'd find longer distances tedious and will possibly revert (like the OP)

The standard 5 speed ratios are fine for a Sierra with a family on board towing a caravan - but are shocking for a 7

OE ratios                                SPC Semi Heli

3.65                                          2.29 (opt 2.48)

1.97                                          1.61                                

1.37                                          1.22

1                                                1

.82                                            .87 (opt .82)

There are touring ratios and SC options too

"shocking"? Amazing how all those Caterham race cars managed with such useless gearboxes.

The gearboxes are not useless, merely the ratios are not correct for the car.

Racers moving beyond Grads fit the SC CR gearkit that is permitted by the regs, didn't see them sticking to the OE ratios.

The ratios feel better with the Crossflow Supersprint and somewhere over 150bhp than with the VHPD K series (about 190bhp) in the 21.  I need first in the 21 quite a lot but not much in the Crossflow.

Whether the expense of changing the ratios in the box is worth it for a difference in feel, I'm not sure.  I'd hate to go to the expense of swopping everything over to find the differences marginal for the way I use the cars.
