Alternate trans.

[Paul Butvila]

Has anyone considered the SM transaxle from the Lotus esprit? My 1977 series one trans. is the Citroen SM. After speaking with Harry Martins in the Netherlands (who rebuilds to new specs) quote from Harry "I've heard from people using the same gearbox in race cars with more than 350 hp"
His email is... [email protected]
if anyone wants to look into it. Just a thought.

I think you'll find that first, the gearbox is getting more than just scarce now-a-days.
It was originally changed from the Citroen box to the Renault in the Esprit because the power available from the new Lotus engines was greater than the Citroen box was gauranteed for and also that Citroen was discontinuing production of the box.

Lots of folks use the Renault UN1, which is the transaxle from the later model Esprits. Upgraded they can handle decent power. But, in North America they are not used much because they are relatively hard to obtain on this side of the pond.
