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. |

which motor and injection system are on the car?
you can learn fuel injection there is a lot of experts around here I am not familiar with your mechanic's term of "impulse injector" as there is no part with that name... so the mechanic is talking about something with a different name... possibly the MPS manifold Pressure Sensor but there are other items it could be. I'd look up brad anders website and read it 3x then go part by part and test each of your Fuel injection components some description of how it was "running poorly" when it was parked would help also If you fix it yourself... your probably talking about a few hundred dollars you may do other maintenance things like changing out all of the vacuum lines while your there... and that could cost a little extra... but should not run up to the 1500 limit your expecting for the carbs. The Fuel injection system is not very happy with cam lift. so depending on which cam you put in... that may matter also brant |
