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. |

@bmtrnavsky
to the OP - i am guessing the impulse sender he is referring to is the MPS the round silver thing, probably was shot when the car was parked. You can rebuild it with a kit from Tangerine racing or source one from someone here, or Jeff Bowlsby will rebuild yours and tune it for factory setting, you will fine tune it- read PB Anders--- Jeff makes new FI harnesses and the alternator harnesses from him or 914rubber. IF the FI points plate is bad , there are some out there, i have several, someone will sell one to you, and you can put a Petronix or Compufire electronic points module in the top end OR just spend $400 get the 123ignition distributor and eliminate all of that. new CHT sensors are available, good functioning AFR are out there. Get all new vac hoses from Dr914- George at AA and all new fuel lines, new spacers and seals, throttle body gasket and intake runner gaskets., your injector seals should be replaced too, . I am in the keep the FI camp on this one, and to say that parts are hard to come by for the d-jet system is just not accurate anymore at all! there is not one part for my 2.0 d-jet that you cant get new or NOS or reman. its old so what ever you do you will need to clean your tank and lines and get a new pump and filter. when i bought my car 12 years ago, all it needed was clean tank, new lines and a new MPS, it fired right up. took less than a weekend, all the information i needed was right here on world or in the Haynes Manual and PB anders site. So YES you can spend less than $1500 and replace all that with new and refresh your motor drive it and enjoy it. FI once set will be less maintenance than the carb solution, been there done that got the t-shirt. |
