Manual Cosworth?

I'm put off the 24v V6 engine because it seems there wasnt ever a manual gearbox attached to it from the factory 
Was there one? Or has anyone ever converted one to manual, and if so what gearbox/parts would you use to do this?
OR - would you put a 24v engine into a manual car, is that easier?

Dark Destroyer has a waggly stick cossie, its superb. I know he hasn't posted for a while, but maybe he could point you in the right direction.
We saw the car at a couple of mids meets last year.

The usual way to do it is to use the diesel gearbox, you need to change the pedals too as you now need a clutch
There is a lot more to it than meets the eye though but it can be done.

That sounds like a terrible idea, wont the gearing then be incredibly long as diesels dont rev very high? You'll be able to hit 60 in first, or something like that!!
I would have thought finding a 12-valve V6 car and dropping a Cossie lump in would be a better bet - no?
edit - no, as they're all autos too, lol. As you were

That 2.0 8v gearset coupled with a 4.27 diff would be great for my (virtual ) sprints down the quarter mile, got the standard 24v torque/weight/diff at the moment on the MT75 ratios, struggling to get below 16 seconds quarter mile and 8 sec 0-60, the 4.27 diff only shaves half a sec off both times 
I'd love to know how some people claim a 6.5 sec 0-60 on the shorter diff/autobox, 'cos I can't get anywhere near that unless I lose about 500kg from the body mass

I can get that in mine, admittedly it was done with a stopwatch but we did a lot of runs.
Have also done a good few runs alongside a standard Porsche Boxster 2.7 24v 228 Bhp with an official 0-60 time of 6.4 secs and there is nothing in it,
Will try and get it checked properly sometime
I did in in Sport mode with OD button on

Are you doing high stall starts? i.e. foot brake on, get revs to 4500rpm then launch? Just asking as my totally standard cossie got the 1/8th in 8.06sec @ 60.46mph and full 1/4 at 16.2s @ 91mph.
Got to agree with Highlander that the 4.27 diff should make ALOT of difference to 0-60 on an otherwise standard cossie.

Tiberius, You sound like you have had you car on a dragstrip 
That is the only way to get the proper info. stopwatches and racing along side other cars gives you an idea, but not accurate enough. 16 sec in the quater sounds about right. Anyone else had their cossie on a drag strip?

you need more then the diesel box, as you onlyneed the 'gear box' part of it
you'll need a sierra 4x4 box for the bell housing and then the special tools to separate and join the 2 together (sierra bell housing on diesel gearbox).
you need the diesels prop shaft to
you need a sierra flywheel and a full escort cosworth clutch kit. you have to use the cable clutch form the sierra unless you want to have the bell housing welded/machined to fit the scorpio's hydraulic thrust bearing, so its either mod the scorpio clutch pedal to take a cable or mod the sierra pedal box to fit the scorpio.
thats just the mechanicals, theres the speed sensors and making the cruise control work when you dip the clutch to turn it off.
then fooling the ecu into thinking the car is in park so you can start it!
ive got the bits and i can tell you its not cheap mod lol, you could buy an early cossie in fact for the costs

I am thinking of doing a manual conversion on my 24V Cossie. Is the Scorpio diesel box an MT75? (same as the Transit one?). My intention was to keep an eye out for an XR4x4 V6 MT75 box and a 4 cylinder MT75 box and swap the front casings over. Then I've got a 2WD V6 box and a 4cyl 4x4 box I can sell on Ebay or somewhere. I've also considered a 5-speed Type 9 gearbox (as in early XR4's I believe) as V6 ones (or bellhousings) do crop up occasionally but I dunno whether they're up to the job? The Park start can easily be solved with a switch under the clutch pedal I would think? Then I just need a pedal set and a clutch and flywheel right? Are there any issues regarding the starter motor does anyone know?

the diesel box is a mt75, the trannie box wont fit so dont use that! you'll need an escort cossie clutch set (arround £180 alone), sierra xr4x4 flywheel, a prob off a manual scorpio
diesel boxes are rare finds and go for good money when they do come up, you can use the later 2.3 manual box as it has the same gearing but there even rarer,
it will have to be a cable setup not hydraulic, and the part start can just be linked out, if your car has cruise control you'll also need to link an off switch to the clutch pedal so that it doesent rev out when u dip the clutch
as i said before its not a cheap mod to do at all

That would do it but its a bit pricey for me. I'm gonna bide my time looking for an xr4x4 box and a 2WD 4-pot box and crossbreed them. I reckon I can get both boxes together for less than £200 and have one to sell afterwards.

that box uses the 2.3s mt75, it would work but its not as good as using a diesel box
and i paid roughly £150 for each of the 2 boxes
the cossie clutch was about the same
