RE: ford type 9 gearbox with 4age engine
I guess if you used the Lexus 'box as a 5 speed, discounting 1st gear the ratios are not bad for a rally car.
(2nd gear used as 1st would still be a bit high even with a 5:1 final drive)
1st 3.874 26mph 7500rpm 185/70/13 (5.1 F/D)
2nd 2.175 47mph 7500rpm 185/70/13 (5.1 F/D)
3rd 1.484
4th 1.223
5th 1.000
6th 0.869 116mph (5.1 F/D) ideal ??
For a 6 speed gearbox the best budget one would be the Caterham 6 speed
1st 2.69:1 40mph 7500rpm 185/70/13 (4.778 F/D) 38mph 7500rpm 185/70/13 (5.1 F/D)
2nd 2.01:1
3rd 1.59:1
4th 1.32:1
5th 1.13:1
6th 1.00:1 109mph (4.778 F/D) ideal ??
Aluminium cased, Ford fitting, 1-1 top gear and ratios perfectly suited to a 4.778 final drive
