but seriously guys...... the guy puts in all the internals and most likely they use Motec computer (M600 + Drive-by-wire throttle module + other modules) (if I am not wrong)... so I would say it will be around 35K mark for the conversion... and they can boost it up safely from there....
cheers,

EDIT: Just found out that hey are using M800... which is more expensive than M600....
