to be honest, the parts for the car alone make it worth more as a whole, all the brackets, the charger, the smaller pulley, the intercooler and silicon, TT inlet manifold and KR
lower half, the exhaust system is £600 on its own with the 4 branch, these parts are all in good condition. I did not skimp on parts when doing the engine. the megasquirt was £900 fully fitted
i spent the best part of £2.5k on engine gear for that car, i did skimp on other bits, and in hindsight (a marvellous thing) i should have taken things easier, and maintained the engine first, before charging, but we're only young once.....
when i sold it the bodywork needed tidying, as did the engine bay etc, the mapping needed finishing, and the electrical issue needed sorting (the alternator was heating up and melting the belts)
i would buy this car back if i had the space, and pour the money into it that it needs, it's still the only one in the world, working or not, and as has already been said, with around £2k and many hours and some TLC, it'll be back to it's full potential
personally i'd whack all of the charger gear etc onto a KR, it'll be correctly mapped for that engine size
