If it's of any help, my Turbo diesel 2+2 has a 3.33 final drive, ( built by the same person as Lord Q was) as Andy has said it's not quick off the mark, but pulls about 2,800 RPM @ 70 MPH in 5th. so still has plenty of power, if driven hard consumption falls to about 54 MPG, long runs can get about 62 MPG, average daily use on local short runs average 57MPG. I never feel like I need another gear, but have thought a normal petrol engined final drive would improve acceleration, but of course reduce the fuel economy. The gearbox/final drive are the Mk 2 Fiesta ratios for the 1.6 diesel, (as far as I know) all as supplied by old QSC to the original builder. It uses 185/55/14 tyre's. John
