As one whom is good a blowing money on cars........ listen to the people above that have suggested getting a fg turbo engine and the plenum and turbo side attached!!!
Ive just done a full fg drive line in my BA ute tr6060, npc twin plate clutch, built tail shaft, built fg long, with a few other things bolted on as well and im 25k down the drain and that's after putting almost 30k into it already! was a 7k buy stock now a 60k fark around.
But if u insist on your avenue ( shakes head ) I have a few old parts off my BA turbo engine. like the heads... a gt3582... FG turbo front brakes 325mm rotors.... 3 inch plazmaman hot and cold side piping to suit B series engine.... Atomic valve springs.... nothing has done over 15,000km ( except the turbo and head ) @ROB83R mite have a say on what is available!
