We are building a 75 conversion with a freshly rebuilt stock 69S 2.0. I have a set of 914-6 webers that were just rebuilt (jewelry), and the fellow that sold the motor has offered up the injection for it.
I really wanted the sound and stock look of carbs, but my friend said that the injection provides close to 40hp for this motor, and sounds better than carbs?? Any thoughts? |

My previous 914-6 had a built 2.8L with RS spec MFI. Yes, it was difficult to cleanly start cold. It was fitted with a manual enrichment switch on the dash; "ignition on, hold cold start switch for a count of 8 with full throttle then engine crank to start". It was easy to flood and often idled badly or stalled when cold. The MFI pump is also a potential source of oil leaks.
Never ran the engine with carbs, so I can't say for sure about improved warm engine performance other than the throttle response was pretty sharp. Was it worth it, not really. Well set up Webers will do most cars quite well. |
