It seems like yesterday, but I recall running an engine at WOT for a short time, cutting off the power and coasting to a stop. These days we have air/fuel readers fed information from 02 sensors, with mapping, blah, blah. I suppose some of us older guys have gotten up to speed with tech, but not this guy. Our recent 914 purchase had previously received a Holley 2V carb conversion. It was starting/running decent, but pulled the engine to repair a bad oil leak. The front (hub) seal was loose in the case, so it seems as though I found the oil leak and also decided to pull the plugs for a quick clean. I was pleasantly surprised to find all the plugs a light tan color.

Might be a task to get this old dog to change, but I am considering either twin Webers or cobbling together a L jet system from several boxes of parts. I know the carbs will work, and I have many concerns with 50 years old parts/sensors/ECU/...

L-jet is fine as not too much to go wrong,ecu's seem to be pretty robust but the real issue that comes up is the AFM which can be worn out and the air gate (flap) sticks up ,appears to be a few reman units around for reasonable money however.
FI looms suffer with the heat but can be repaired,my next build will be with L-jet and I have otherwise good parts except for the AFM which is the reason the last owner of the system went to carbs.
Its a good system IMO problem it just came with a really gutless motor (IMG:style_emoticons/default/sad.gif) ,the fact you can bore and stroke the motor and not change the system is good.

The consensus here is FI, almost exclusively. I probably have three boxes full of D jet and L jet parts from a few parts cars and are semi considering going with an L jet on a current build. Several years ago an '85 Alfa spider came my way and I fought with it's L jet system until I finally ditched it and went with twin Weber 40 DCOE's. Still running great. In a couple hours I can have this current build running with twin Weber 40 IDF's, but I sense it will take weeks or more if I attempt L jet.

And you could take the easy way out and be driving a Boxter too. (IMG:style_emoticons/default/happy11.gif)

I considered that option several years ago, but have an allergy to computers. My '16 F150 is enough vehicle computer for me. Hence, my hesitation to unbox a bunch of L jet parts and get her running.

BTW: still using a flip phone
