Different Carb or EFI

There is a "dead head" EFI system that looks like a carb and doesnt require a return line. Run a external inline Bosch fuel pump like off a Mercedes 450 and you should not need a sumped tank. Dont know about nitrous and you need to get the injectors to match your HP level, the stock ones probably wont do 500HP but your motor may not make 500 either...? here is an option..Megasquirt demands a huge amount of fabrication, I know, I still have an unassembled kit on a box somewhere.
