Carbs or Fuel injection ? Options

[ILM914]

Hi folks a 914"expert said carbs will burn the valves on a 914 and not run well. Is this true? is the fuel economy worse when using duel carbs? Would you run orig fuel injection on a 2.0 or carbs thank you, Joe

The 911 engine used in the 914-6 was designed to use carburetors, and was later converted to CIS (on the 73.5 911T), then Motronic fuel injection (on the 3.2 Carrera). Both fuel injection changes improved both performance and fuel mileage.

The VW based Type IV motor was designed with fuel injection from the start. When it is backdated to carbs, both the performance and fuel mileage suffer. When you change the internals on the engine and exceed the limits of the stock injection then you justify going to carbs. And these days, the programmable EFI out there is a far better choice than carbs.

There is a reason that carbs are no longer sold on any production vehicles in the US. Fuel injection is a far better, more efficient system. Why would you want to go back to something more primitive? Gas is too expensive to waste these days.

The only reason we still have the factory Weber carbs on our 914-6 is it came from the factory that way, and we are trying to preserve it and keep it as original as possible.
