So if I want to fit a T5 box will I need an adaptor? do T5's bolt up to the aussie 4speed box/trimatic patterns or turbo patterns?

T5 is turbo pattern..
cheapest way to do it is to buy a vn to vt 5 speed car..they are at salvage auctions everyweek and anything up to 15 years old is stat right offs in nsw..price wise vn vp vr ss 5 speed go at salvage auctions as a high mileage pig/untidy low price 1200 to a tidy well looked after but damaged 2200.. vs vt are generally more expensive because of low ks and also because of the roller cam motor and the blocks are already relieved for stroker cranks..2200 to 4k dependant on damage...
the better wreck you buy will return you money wrecking out the parts you dont want.
you need hq to wb or lh lx v8 sump and pick up..hq to wb engine mount brackets..hq to wb water pump and pulleys.to swap onto commodore motor..
