that is just mad, how much you reckon that cost to build? 
id say 200 - 250 k not including the labour, Simon Norris built my pulsar engine and his short wheel base evo 9 is as much of a beast as the dhalback golf, 300k - 350k would build you another short wheel base evo,
almost every nut and bolt has been replaced or uprated, all aeroquip fixings everything on the car is there to cope with massive strain, alot of R&D, alot of carbon, alot of custom parts, and components to cope i.e custom sequential straight cut getrag gearbox adapted to fit the audi lump,
