Nice conversion, had a couple runs out in my friend Andy's 1.8T engined Elise when he did one of the early conversions:
GT28RS turbo and Emerald ECU, 350 bhp
I believe he wrote some kind of technical or how to manual for this conversion, which he was asked to do by one of the companies that are known for this sort of work...
Either way, this was late 07/ early 08 I guess so quite a while ago now.
Ace car.
