Hi everyone. I am building up a project car and wanted to check a few details with some more knowledgeable people. Is the back end of a Granada Cosworth the same as an 2wd Sierra Cosworth? i read somewhere the diff is the same but i wasent sure about the rest. If its the same I assume it all bolts on to the back of an Escort Cosworth? and I am thinking the 2wd Sierra Cosworth gearbox bolts straight on to the 24v Cosworth engine? I'm sure you can see my plan here Thanks Stephen

 

Yo mate - welcome to passionford. There are folks on here who easily know the answers to your questions. I suppose you could give an idea of the year of cosworth scorpio (it was no longer a granada at that point iirc) that u are thinking about using as a check.

I think the plan is an escort cossie shell, v6 cosworth 200bhp lump, t5 gearbox with a shortened prop and the rear end (diff and beam) from the scorpio.

Can anyone give us a clue?

Cheers!

T5 box will not bolt to the V6 block the bellhousing is diffrent and the input shaft is longer on the V6 type 9 boxes and mt 75,s, the rear beam is the same,,,i think the arms are the same but not 100% sure

the scorpio 7.5" diff is the same dimensions as a cossie but i think it was 3.3 ratio and not 3.6 like the sierra cos

hope that helps

welcome to pf

 

the early beams and diff are the same,but not many had the slipper diff.
the later beams and arms are different,but they will bolt in

diff ratios are the same.and the diff shafts are interchangable .so can use 4x4 or 2wd driveshafts

 

i have seen loads of scorpio cosworths on ebay for 300 to 500 quid,just no manual gearbox ones

 

thanks kevin thats given me something to work on are the input shafts interchangeable?

 

i thought all the scorpio cosworths had a slipper. well the mk3 ones anyway ..the later fugly ones went to traction control.i think?

 

i,m not sure mate,possibly. but if you want a box to mate straight to the V6 you will need to find and MT75 2WD box from a 2.9 granny..but happy hunting for one of those...or an earlier type9 box from an xr4i will be an easier find

 

i dont think they did manual ones, but yea they are pretty cheap and I thought an ideal donor car "earlier type9 box" i read they dont handle the power very well?

 

24v scorpio cosworth isnt very powerful though, if you have an escort cossie shell why not pick up a rusty saff cossie there are plenty around, everything will go straight into the escort shell with a shortened prop and the tuning potential is massive compared to the 24v motor

 

because i will die and waste a perfectly good yb engine tbh ive always wanted a V6 escort since i saw a prototype picture many years ago. and i want a bit of a sleeper

 

the bits on the granada you can use that are the same as the sierra 2wd cos are:

rear beam because it takes the 7.5 inch diff
rear hub carriers

the parts that are the same as a 4wd cos are:

rear brake calipers
rear hub carriers
one of the driveshafts (passenger side if i remember)

that said, you can just unbolt the front and rear from the granada and bolt them into the escos shell and you only have to change the front struts and the rear springs and find a shorter prop

leave it auto until you can find a suitable box, t5 has much better ratio's than the mt75, all you need is an adaptor plate for it

 

cheers dojj, i did think most of the parts would fit, i just needed to be sure

 

im not 100 percent but are the granada hubs 5 stud ?

 

wouldn't be much of a sleeper if it looks like a escos with a slower engine in

 

yup, 5 stud hubs and they use sierra 4x4 fitment struts
which is why you need to change the front struts as the tops are different and they make the fornt of the car sit way to high
the tca's on the granada are wider due to it's wider track so you could change them too
also remember that if you are going 4wd you will need a 4wd front arb and if you are going 2wd you need to keep the 2wd arb as the angles are different where they go into the tca's due to different drive angles or soemthing

rianbird etc will be able to give you proper geomerty goings on

 

possibly slow enough to fall asleep in

 

Yes

 

It won't look like an escort cossie - probably have a more regular escort front end and no whale tale. No need to make presumptions.

was just a joke mate

 

2.4i granada had the 2wd mt75 aswell,but hard to find a granada now let alone a manual

 

haha i know what you mean, i think with no spoiler and no vents and perhaps a 3i bumper most people will just think its an escort. i was thinking mk 6 front end but it might look a bit stupid. and all the granadas ive seen have 4 studs. ie http://dundee.gumtree.com/dundee/09/33895709.html i think its the older ones that are on 5

 

Although the Ultima Cossie is 4 stud

 

the granada's (sierraish shape) are 5 stud, the ultima's ( bug eyed front) are 4 stud..

 

ive got a mk4 xr3i with 24v cos v6 rwd manual love it!!!

it aint slow and its soooo reliable too

 

mk4 with a 24v sounds fantastic got any pictures?

 

that sounds a god wee motor,does it handle mate?
