Auto For Conversion

[crowsss]

I am putting a rb30 into an old bedford van

what auto is recomended

are boxes from turbo set ups stronger than non turbo

if so would I have to put a different convertor than a turb configered one

to allow for the extra weight and non racing car revs I would be reaching

the van will be running on lpg so the innjection aspect will not come into play

besides I am going to use a manifold of a patrol motor and use a carby to avoid having the hassles of a computer

can anyone tell me what wiring would be needed from the auto I know the overdrive is electric but will the auto change with out a computer

thanks for any help as I need all I can get
