Remember, the search button is your friend.

I believe a peripheral port should be mainly track only, due to the size of the ports, it wouldn't be good to use on a street car. You'd lose a lot of driveability.

MSD ignitions are multiple spark dischargers. They make a longer burning spark, and send out shorter, but more, sparks per cycle. While there is some controversy about them, typical belief is that they increase gas mileage slightly, and make a better running engine.

Any engine can be driven on the street, the question is whether you'd want to. They are practically useless unless you're at high revs, and require an exhaust system likely to get you thrown in jail. It's a race engine.

Waste spark is very common on all types of cars. It means you only need half the number of coils and half the number of ignition driver circuits in the ECU, saving money. All 86-02 Mazda 2-rotors use it (but not Renesis for some reason). Waste spark can only be used on the leading plugs of 2-rotor engines. It can't be used on the trailing plugs (study the animation to find out why) or 3-rotor engines.
