maybe some guru could correct us both, as I'm only 75% sure of what I'm about to say.

Don't know how you meant this, but they're the same thing: 1,794cc rounds up to 1.8 Liters; they're both discribing displacement

controlled by the computer, or by a vacuum solenoid. (I probably misinterpreted what you said). The camshaft rotation compared to the Crank rotation can be retarded(slowed), or advanced(sped up) depending on the conditions, need for higher power/ more performance, or need for fuel economy.

Again, I probably misinterpreted, but I believe that early Fuel injection was a "bolt on" to replace the carb. In other words, the injector was placed right where the carb was, in the center of the intake manifod. MPFI, is when the there are multiple injectors (usually 1 per cyllinder), that still inject fuel into the 'manifold', but right near the intake ports/valves. Most if not all vehicles use this system (some are now switching to DI), it's just a fancy name, like OHV (over-head-valve)
ALL valves are "overhead" the cyllinder.
