I'm considering the purchase of a few 308 GT4's for a small business that I'm running. These would be track cars. But are the carbs up to the task? I've considered the effort involved in converting GT4's over to a Motronic 2.7 fuel injection, and some years ago I converted a carbed KR2 into a throttle body fuel-injected KR2 aircraft, with great success (no more carb starvation during radical manuevers). The Motronic conversion would be the most costly (time, labor, money). In contrast, a conversion to 4 (or 8) Ellison throttle body injectors might be as simple as my KR2 conversion some years ago (unbolt the carb, bolt on the Ellison, installed a Van's solenoid primer kit for cold starts and then I was done!).

tell us more. i'm intrigued. i know you can buy throttle bodies that bolt exactly in place of the carbies, but they're expensive. i've wondered what sort of computer can do just the fuelling, as i already have prog elec ignit. i reckon it's a great idea, and with multiple throttle bodies, should sound pretty much exactly like it does now.
The carbs will be fine on the track, but to maintain peak performance you need to change jets with the weather. A motronic EFI conversion would be the most difficult possible way to add EFI. A simple Haltech e6x will plug into your laptop and give complete and instant control of both fuel and ignition for $1400 including a wire harness. There are TBs that will replace the carbs as a direct bolt-on, you can use motorcycle TBs, you can replace the carb manifolds with a CIS intake to converted to EFI injectors.
