Hi Tony.
My 1.8TD with the Intercooler, which was kindly recently rebuilt by Quantum
Sports Car's, they managed to get an early mondeo engine which happens to be
from an N reg mondeo. This was then mated to the XR2 gearbox and drive
shafts which was in the car with no issues. I have often considered are the
ratio's correct ! I often feel I could do with another gear at 70mph but
lord 'q as he is known does return 55 to 64 Mpg. acceleration is not amazing
but once he is moving i am more interested in him as a long distance
cruiser.
The issue you will have in your saloon is modifying the o/s/f internal lip
i.e. cut it out and glass over to re-strengthen, modification to the top
engine mount and those are the only two mods i have found having built the
1.6 CVH versions.
I would take some pictures for you but my car is currently with Jan in
Scotland so if you are holding out till later on in the year your welcome to
come to Stoneleigh, look, measure and take photo's

To confuse myself further, I tried looking up the various ratios
involved.
I was surprised to find that the final drive of the Mondeo is a lot
lower than the ERST.
ERST has:
Final drive = 3.82:1
1st = 3.15 Overall = 12.03
2nd = 1.91 Overall = 7.3
3rd = 1.28 Overall = 4.89
4th = 0.95 Overall = 3.63
5th = 0.76 Overall = 2.9
Mondeo TD has:
Final drive = 4.06:1
1st = 3.666 Overall = 14.88
2nd = 2.047 Overall = 8.31
3rd = 1.258 Overall = 5.11
4th = 0.864 Overall = 3.51
5th = 0.674 Overall = 2.74
Percentage difference works out at:
1st = 80.85
2nd = 87.79
3rd = 95.73
4th = 103.45
5th = 106.09
So in 5th the engine would have to rpm at 106% in top to maintain the
same speed. 6% difference is not so bad, and should give me some more
poke on the motorways. In the Mondeo, 2500rpm equates to about 70mph.
2650rpm instead of 2500rpm for the same speed isn't going to be a huge
issue.
The bottom gears are a LOT longer, though.
80% engine rpm for the same speed is enormous.
Good job diesels are torquey, I'll need it to get moving..
Or have I got my figures/maths completely wrong?
I'll also have to do something about the heavy clutch while it's all
apart - maybe fit an XR3i item in place of the ERST one.
