Who does the work though.
Less a Haltech PS2000 and the install and tune + markup! = $16,000 left. Then shipping/duty $14,000 left. Then workshop fee's for motor removal and install = $13,000 left. Then exhaust = $12,000 left. Fuel System = $10,000 left. Misc = $9,000 left
You now have $9,000 left to get to 800hp reliably!....how much are the 3.8lt or 4.2lt conversions? and then how much is turbo kit from the workshop going to charge?
Like I said 20K with you doing most of the work is good for at least 800HP.....a workshop doing most of the work at least 600HP....and I am talking with reliability.
