Difficult to say, it was spread over about 18mths. Engine I'd already bought while at UAD, but the machining was about £700, exhaust about £150, dash £500 ecu £600 seat, belts etc was about £800 mapping about £2000 tb's about £200 it quickly adds up. Basically the car was a shell, no engine, basic sporting alloys although it did have the cage and two Eco seats. So basically we had to build the whole car.
So I don't really know, but given that this was the first one there was a lot of experimentation - particularly with the electrics, so the next one to be done should be cheaper, although almost certainly more than the turbo. However, as has been said before I had the first turbo fitted by Autodelta and it was the Novitec kit - it never worked and I had to buy another car because it spent so much time in the garage - so I think it's worth it.
