Cizza. Here are some prices to give you a idea... these prices are Trade Turbo bare long motor = $4812.23 Turbocharger assy = $2956.86 Exhaust manifold = $809.93 Lwr Intake manifold = $331.71 Upr Intake manifold = $216.73 You will need some sort of ECU, whether it be aftermarket or genuine, and you will still need all the accessories as well eg; throttle body, turbo pipework, alternator, exhaust etc. As for fitment, I havent checked, but I dont see any reason why a BA DOHC wont fit in a AU engine bay. And I seriously doubt a used AU tranny will cope with the torque of a brand new BA T motor, especially after you mentioned you are a rev head, so you'll need a new trans too! BA Auto Trans = $6145.65. Which gives us a grand total in parts alone of $15273.11! You could scour the wrecking yards, Id say this will be your cheapest option, but I only know of 2 T's currently being dismantled. I wish you and your wallet the best of luck in your conversion!
