Modify this Geo Metro
Trying to help out my friend Ned Flanders... He loves the efficient practicality of the Geo. However, what modifications should he consider for his Geo to help him in "power-on-demand" situations like this:

Nitrous oxide injection? Propane flame thrower?

Lose the dead weight (kids) and floor it. They move pretty good in the lower gears, not weighing much.

Turbocharger.
Or find a bigger geo storm engine.
Nitrous is cool is cool but it has a start sequence. Have to open the bottle, purge the gas from the line (recommended), get the engine above a certain RPM usually 3,000 to 3,600.
You don't want to leave the bottle open, nitrous could seep past the nitrous solenoid and fill the intake with nitrous then the intake on your car blows up because it's full of pure nitrous.

For "on-demand" power, maybe something like Volvo's transient supercharger fitted to its T8 hybrids.

It's the same answer as in any car- a manual. If your most powerful stock setup is 79hp, why on Earth would you hide even one of those horses behind an automatic?

Easiest thing I can think of is put a micro switch some where along the throttle linkage to turn off the A/C.
Oh my switchable cold air and thermostatic intake worked pretty good.

The solution I hit on with the Superbeetle was to leave the engine stock and resize the front tires. The [left front-driven] speedometer is ~12% optimistic.
A mechanic that road tested it was really impressed until I told him.

79 hp = 1.3 L ( BIG BLOCK)
55 hp = 1.0 L (little block)
If only I had those 24 extra horses of ground shaking power from the Big Block motor...
