Just T16 it, will be a lot cheaper as it bolts straight in with the correct mounts
Forged pistons (rods debatable, but if you can afford deffo go forged), steel caged box, big 'old turbo, after market management, 2.5" or 3" exhaust and other bits and bobs (uprated ARP head bolts, steel caged box etc) and 300bhp done!
