turbod propane questions

Ok this is kind of the subject. A friend of mine has a rock crawler the propane injected. He is looking at turboing it ( we both work at borgwarner turbos ) and were trying to figure out how to do this set up. We have a plan for all the plumbing but we have no clue on what type of a carb to run, what cfm ( It is set up like tfi ). he is only wanting to run 5psi, so if any one has ideas it would be greatly appreciated.



Thanks in advance
