It's worth knowing, any engine can be fitted with fuel injection, it's much easier installation wise if you can get get a manifold for twin Weber DCOE carbs though, as then a pair of Jenvey TB style throttle bodies will bolt straight on.
If there's no Weber manifold, or you want to do things on a budget and use bike throttle bodies, then you either need to make your own inlet manifold, or get one made by someone like Bogg Brothers.
After that it's "just" a question of plumbing and wiring! (Understatement of the year, but you see what I mean!)
The hardest part really is getting enough of a "map" onto whatever make of ecu you've used to actually start the engine and map it. It's one of those chicken and egg situations.
It's great to see someone putting the time and effort into a more unusual injected engine combination though, specially when it's one of the classic kit car engines; people right them off in their heads far too easily, when they can be made to work really well in a Westfield.
