LD28 gear ratios:

1st 3.59
2nd 2.25
3rd 1.42
4th 1
5th 0.86

R. 3.36
Diff. 3.889

Not 'that' far off the ratios from a euro spec 280ZXT :

B/W T5
3.5
2.144
1.375
1
0.780

and run with basically a 3.9 diff.

LB28 gear ratios (for Alans' benefit) :

1st 3.59
2nd 2.25
3rd 1.42
4th 1
5th 0.86

R. 3.36
Diff. 3.889

Transmissions matched to Diesel engines often have an especially low first gear, at the least.

Compare with (Euro) HLS30 and (UK) HS30 FS5C71-B ratios:

1st: 2.957
2nd: 1.858
3rd: 1.311
4th: 1
5th: 0.852

Reverse: 2.922
Final Drive: 3.9:1

Personally speaking, I wouldn't say the diesel ratios were all that suited to a normally-aspirated petrol engine in a sports car.
