Lads another questtion from me..
A sierra 1.8 td type 9 box. is the bell housing gear ratios etc the same as the petrol boxes?
Big question --- can't be much worse than the standard type 9.
The ratio in the diff is most likely different to petrols (no proof, only speculation), but the gearbox ratios could well be the same.
Most gearboxs (deisel or petrol) have top gear as 1:1, exceptions include early ford 5 speeds whith an overdrive 5th.
4th gear is always 1:1 on all 4 or 5 speed boxes -- the only exceptions I know being the 5 speed boxes on early post war British Army vehicles.
I've been led to think that Ford used Pug dieslels for some time. But I could be wrong! Therefore, the bellhousing bolt pattern will be
different to the Ford?
Nev.
Ford didnt use the pug deisel in the sierras. It is a ford 1.8 older version of the 1.8 endura as in the escorts and mondingo's.

The 1.8TD was yet an another evolution of the Kent family --- it came a long long way from the 3 bearing pre-xflo 998cc in 105e.
Not a great diesel compared to the 2.3 pug.

my impression is that 4th on most cars is 1:1 and 5th comes out something less, like 1:0.88

i drive a 2.3d sierra for work all day (you can tell how sucessful we are
) however, it is in a car that started with a 1.8td.
i have concluded that the 1.8td box has much shorter gears than a normal type 9 box. The 1.8td has a 3.92 ratio as standard i think (feel free to
correct me if you know otherwise). Short diffs should go with a revvy engine, since diesels arent revvy i assumed that the gearbox ratios must be
longer to compensate.
My 2.3 diesel has fairly normal ratios i believe, hence the fact that it started with a 3.38 diff to make up for the lack of revs. 
When forum users ask for advice or facts, why do people who have no idea what they are talking about try and give definitive answers?
In my (fairly long) experience of using this forum there are only a handful of knowlegable contibutors - Gazza285, Stu16v, the conrodkid and NS Dev
being the only ones I can think of!

Are you sure that the Endura Diesel was based on the Kent? I know the Endura petrol engine was, but the diesel bears no resemblance that I can see. Ford SA based a diesel on the Kent, but these were never offered in a European Ford that I know of.
Back to question in hand. Are the type 9's different bell housing and bolt line up on the petrols and diesels?
The bellhousing to gearbox bolt pattern is the same on all the type 9 'boxes, is this what you mean?
I can't really speak for the 1.8 engines as I have only had limited experience of these in front wheel drive but I do know the 2.3 engines used
the long nose box with a different bellhousing for the Peugeot engine, so using one of these boxes with a fourpot bellhousing is out of the window.

Ford did change the ratios in the type 9.
The long input shaft (V6 and 2.3td) had a first gear around 3.3.
The short input shaft used in most petrols had a first gear of 3.65.
The p100 had first gear of 3.91, second of 2.29 then matched the short input shaft.
having spent the last 20 mins web surfing i've found one comment that the 2.3 diesel uses stronger first & second gear but they are close
together. This sounds a little like the P100 ratios.
must go to bed..........soon......
anyway, found a german version of the ford technical manual for the type 9. It doesn't list the 1.8td but does list the 2.3.
This claims ford did 3 versions of the type 9/N gearbox and it seem the p100 gearbox was the same as the 2.3 diesel.
The ratios are,
I4 / other/V6
3.65/3.91/3.36
1.97/2.32/1.81
1.37/1.4/1.26
1.00/1.00/1.00
0.82/0.82/0.83
(technically my column headings are wrong as the I4 gearbox was also used in the 2.0 v6 and the 2.3 v6 but i don't think they made it to the uk
mated to the type 9 in the sierra)
Another thing that I didn't bother putting down before is that the 2.3 diesel 'box uses stronger selector forks than the other 'boxes (don't know if the 1800TD is the same) which is no bad thing. They fit into the "normal" type 9 too.
Oops didn't mention that the 'other' box when used against a 2.3 diesel was long input shaft.
(no i don't have a life & yes i do spend all day & night reading this forum)
Thats what i wanted to know.. Im bidding on one on ebay u see as im too lazy to go to the scrappies.
