Phil et al,
about 5 years ago I fitted a 5-speed gearbox from a T18 Toyota to an S4
Elan. The ratios were dreadful so I had some straight cut gears made by
Hollinger Engineering here in Melbourne to match those of the ultra close
box in the original Elan (2.5:1 first gear). This combination allied to a
4.2 rear axle ratio gives a great set-up with about the same overall
gearing in "top" as the original drive train. The gear stick posiotion had
to be re-engineered and I required a 16mm adapter plate between the bell
housing which was readily available here to suit japanese 5-speeds into
Escorts etc. I tackled the clutch throw-out by simply welding an alloy
block onto the bell housing where the original Elan one was and used the
Toyota throw-out lever and a "small" diameter slave cylinder from an
Escort. The speedo drive was very tight and very tedious but with
sufficient patience I got it to work. The gearbox mount to the chassis was
straight forward with a flat plate made to fit the appropriate Toyota
mount.
The whole job was tedious , time consuming and expensive but the owner is
very happy with it and as the car lives in my shop I drive it often and it
really works very well. With the 150hp stroker motor fitted to the car and
14*6 Minilites with good rubber it is a real weapon.
Good luck with your conversion.
