Gearbox adaptor

[wayneb911]

Can someone confirm if the renault and the citreon transmission for the 2.2 engine use the same face pattern? ie not that im thinking of doing it but would a renault box bolt straight to an engine in an 1981 2.2 car??

HI Wayne,

the citroen gearbox has the rear disc inboard, the renault not, how do you think to do for that?

The renault car have a different chassis/suspension, I don't think will be a easy modification to do.

Just my little opinion.

The bell housing pattern is the same for the Lotus UN1 and the SM gearboxes.

However the bell housing on the UN1 is a Lotus specific item, so just any old UN1 won't bolt on.

As mentioned the rear brake position between the two is an issue, if you get a UN1 for your car you will require a whole bunch of hardware to sort that out, at which point you are not just limited to the UN1 as gearbox choice. The whole point of using the SM box is that you won't need to re-engineer the rear suspension/brakes.
