Yeah they have Efi.
I "thought" that the issue with this was not so much getting it running, but the K10 gearbox being made of metal not dissimilar to toffee. Which is why the turbo engine in the figs only got an auto box and using the auto gives you performance only negligably greater than an Ma12 because of the mechanical losses and extra weight.
Though of course what the factory consider reliable, and what you could conseivably do with an actual car are of course very different. Good luck with it, hope it works out!
