hay guys got a very original 74 rxt and was wanting to turbo the 12a engine i want to try a carby turbo setup A :becouse id like to keep it old school and B :its cheaper. i already got a t3 turbo and a 48 mm webber carby so can this work or not. thanks

is this a stupid idea

if you want to keep it oldschool, i'd go with a roots-blower rather than a turbo

read up on blow thru setups, and draw thru setups, that will help you figure out in which route you need to go. Old school is always a nice weay to go, but as things progress it becomes harder to source parts.
