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. |

You can carb it!
You will not need to change the cam, you should as the one that is in it is probably setup for FI, but you don't need to. You did say it is a mild one. Which one is in there? You can do it for under $1500 depending on your mechanics labor rate. The carbs run close to $1000 I believe for a set of 40 Webers. 40 Webers are what you should go with. You will need a different Fuel pump or a really good regulator to drop down the FI pump. The linkage is where you can spend a lot or a little. Tangerine Sync Link - Set them and forget them $300 CSP - good quality center pull system $150 Hex bar - Cheap garbage. Will work at first then start to deteriorate free when you buy a kit The $1000 kit should also contain the manifolds. You may need to buy the phelonic? spacers/gaskets between the intakes and the heads. So you can see you get pretty close to the $1500 mark in just parts. I feel carbs are very reliable and simple. BUT but BUT but BUT... FI does work well when it has no vac leaks or wire issues and was meant for that engine. It is reliable once it is all working. You can probably get almost a completely refreshed FI system for $1500 or under. I don't like dabbling in the dark magic as my brain is too simple to work with complex wires and hoses and wires and thingies. From what I have worked with is runs nice. The jury is still out on whether I like djet or ljet more. If you replace the wire harness and the vac lines and test all the components individually, replacing the ones out of spec, you should be pretty close to a reliably running car. Also, learn the items yourself since most mechanics don't know the simplest spell in an ancient old magic. |
