Yeah man 6K is mental.
It was roughly estimated to be less than that but I always new the cost would increase once the build was started (always does in a job like this). Dave Ellen would tell you same thing about when he first fitted his own turbo and he bought a (American) kit!!!
But you also have to take into account the I have included the cost of a complete stainless exhaust from turbo back and a Kazama rear pipe and I also have a stand alone ECU which costs more than the piggy back ones.
I have also used the best parts for everything instead of cutting corners (I'm not saying anyone else has cut any corners btw).
I am very happy with the work so far and will be even happier when it is on the road!!
So yeah, a lot of money but hey, wadda ya do???
