Video: Electronic ignition installation on a 1967 Porsche 911S

Few systems on an old car offer more potential for persistent troubles than the ignition system. Points, rotor, condenser, cap, coil and wires can — and do — fail. More often than not, the points are the culprit. Never fear: A modern electronic ignition conversion can eliminate pesky points. They're a breeze to install if you know what you're doing. Check out our three-video series detailing such a project on a 1967 Porsche 911S.

    Real good video of the installation of electronic ignition in a 911 Porsche. Do you have one for a 327 Chevrolet 1966 ss?

    What's easier than replacing points with electronic ignition? Not replacing points with electronic ignition. I installed a Capacitive Discharge Ignition aka CDI aka electronic ignition from JC Whitney on my 69 Camaro V8 in the early eighties. The stock points are used to control the timing and switch the CDI which then fires the coil. The dwell adjustment is irrelevant as the CDI controls the switching of the coil. I use the stock coil as well. Points fail due to the high current directly switching the coil. With no high current needed to switch the electronic ignition the points last forever. Or at least I haven't had to touch them or adjust the timing in 30 years! Installation couldn't be easier. Hook up power (pull from coil +) and ground, connect the wire from the points to the CDI and another wire from the CDI to the coil - and that's it. Don't even have to open the distributor or touch the high tension wires. Car starts and runs great and plugs are always clean.

    My 911S (as they all were) was always prone to plug fouling due to that aggressive cam profile and lots of fuel..especially putting around town. I went to a hotter Bosch plug and coil and then made it a habit to redline it through the gears occasionally to clean it out...tons of fun! Nothing sounds like a 911S in anger! I miss it. The electronic ignition and hotter coil make sense. But CRIMP CONNECTORS AND ELECTRICAL TAPE ON A CLASSIC PORSCHE??? OK maybe you were in a hurry to get the filming done but come on, anything worth doing is worth doing right! Did the customer think that was OK? I think I would solder and heat shrink the splice and put it inside the distributor then run the wires into the original harness and then solder the bayonet connectors at the coil end. Otherwise great video showing how simple it is. Thanks

    will this work on a 6 volt system
