You will need a carby suitable for either a Blow Thru, or Suck Thru setup.
Basically, the turbo will blow air through the carby, as per a normal setup with a throttle body. The carby will need to be jetted according to the flow rate of the compressor. Tricky stuff to get right.
The Draw-Thru through setup sits the carby in front of the turbo. The turbo inlet sucks an air/fuel mixture through the carby, and then compresses it.
