I've been tinkering with a Megasquirt controller, it seems very promising. I'd guess it would never be cheaper than a pair of carbs because of all the additional parts you'd need to round out the fuel system. But some company (can't remember off the top of my head) makes SU-style bolt on throttle bodies, and you'd only be using two injectors. Add an O2 sensor on the exhaust for feedback and you'd have a very well running old B20. And tuning is a snap - you can tweak each part of the fuel air curve independently, they even have some programs that can retune the base maps automatically for you as you drive around (you don't want the base maps too far off optimum). The regular MS controllers handle up to 2.5 bar boost too.
