This generally gets all confusing because people say one thing but mean another, so... Electronic points: They repċ mechanical points and remove the need for a condenser. Never have to be adjusted and they don't experience point float at high rpm (>5000, for those of us who feel speed-of-light travel is just too slow ;) Overall, they are superior compared to mechanical points. Bad side: If, somehow, they get fried then you are totally immobile...but that's why you always carry a spare set of mechanical points, right? Pertronix or Compufire are the name brands and having used both in my cars I can say neither one is better than the other. Five years and all kinds of daily driving conditions and I still have my original Pertronix in my Squareback. Electronic ignition: Compufire or Mallory are the main name brands. Crane and Allison (Accel as well?), too. Use high voltage coils and/or multiple-sparks (capacitive discharge) to improve ignition. Best observable results in above-stock-compression engines and unnaturally aspirated engines that use turbos or superchargers. Spark gap can be enlarged. Just about everyone who's used one doesn't go back to stock. Computerized ignition: Jacobs Electronics is the only brand name I'm familiar with in this category. Superior to electronic ignitions and will work in any engine. Each cylinder gets a custom spark, varying in power and duration, according to the needs of the cylinder. Will send a spark to the cylinder in the event of a misfire. Spark gap should be enlarged. No need for multi-point or split plugs. I use this in my Squareback and have had nothing but positive results. Electronic distributor: Again, Compufire and Mallory are the main brands (I keep thinking there's another, anyone?). The ones I know of are electronic ignition with a coil per cylinder. The "distributor" is now a sensor on the crank and, when triggered every 180 degrees, a pair of the coils will fire. I keep reading that they are recommended for racing engines and not too desirable on street or daily driver cars. Definitely will have difficulties installing one on a T3 because of t6eġ ulley our engines use. Some use the flywheel but that involves more work. ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
