Well I sort of assumed you would only want to run LPG to improve emissions of a carby setup. I don't think there would be a problem with LPG on an compliant EFI setup, you would have to check.

Remember you've got to fit that bottle somewhere and will end up with very little boot space.

There are a few LPG Cobra's around, all the ones I have seen have been carby LPG.
