My buddy is doin a RB26DETT in his 240sx and wants to run turbo 6 with it. the problem is that the rules state you must remain single Throttle body if the car came with one. well the KA that was the stock motor did have a single TB but the RB motor comes stock with ITB's so would the rule apply to this set up since the motor in the car has ITB's from the factory?

anything you guys can tell me will help a lot.
