Probably the speedometer has different ratio, and if you think that 140km/h is pretty enough

, you can use the original EL/ELX model (the last one y. 1994-2000). Otherwise it won't show the correct speed. Have no idea if there is mph or mixed as well. The speedo cable of this one is a push fit too.
RPM to be turned to 2 cyl. (If there is no potentiometer, as Pete says, it will need something more).
It's pity that the factory haven't do it at least for the "Happy end" model

Looks like real car

And there is no the hateful tire pressure drawing.
