      TBI sizing w/ single turbo

      Can a 2 barrel TBI unit (2") with 68 lb or 75lb injectors handle fuel delivery requirements for a small block chevy 327 bored .030 over using a single turbo at 7 to 9 psi ?

      I'm thinking I may need to upgrade the TBI unit, or switch to another type of injection. I'm looking to make about 450 HP.
