M100 Elan gearbox

[Robmarriott]

What is it? Isuzu? Lotus? Vauxhall?

I would take a look on the Lotus Elan Central website/forum - bound to have the answer there.

Isuzu, pretty solid not much goes wrong with them, which is why they are so cheap 2nd hand. They can take a lot of tuning too and the Elan comes with a sports clutch and they are very reliable too.
