My 914 has been sidelined since 2012 for a number of reasons but was parked not running. Pulled it out of mothballs and hauled it over to the local vintage Porsche mechanic who said my impulse sender had no signal. He said he was unable to source parts for it and was unsure if replacing that part would get it back on the road his recommendation was to convert to Weber 40's. I'm not rich so I understand his hesitancy to open what could be a very expensive can of worms.
So here is where my questions start I'm just looking for a solid running reliable car that I can drive on trips and maybe autocross 2-3x per year. anyone have a source on the impulse senders? can they be rebuilt? Is the Carb it advice good? I have a basically stock 2.0 with hydraulic lifters and a very mild cam. Will I have to change my cam to convert it? what's the best carb? I have seen 34's 40's and 44's people seem to do all three are there pros and cons to each setup? Can I get this conversion done for around $1500 in parts and is it a achievable project for an average mechanic? I suck with electrical but I have plenty of tools and am not afraid to learn as I go. I have done head gaskets and other mid level projects before. |

QUOTE You will be much happier than the single pinto/weber carb in both performance and mileage. That carburetor (or any single) fitted to these engines is a quick way to experience the worst ownership experience possible. People go to these because they *appear* to be simpler and easier to tune than duals.. This could not be further from the truth. These carbs are damn near impossible to tune, primarily due to the long runners that allow the fuel to form droplets and enter the chambers as liquid that has fallen from suspension and lost atomization characteristics. This means the engine always performs and tunes like it is rich, even when it is lean. I rip them off, and crush them with my bulldozer, or tracked armored personnel carrier. |
