The Engine Management Computer can adjust the fuel quantity, and the
ignition timing, and several other parameters so the engine runs at
it's best. Unfortunately, it can't adjust the altitude, it can only
sense it and adapt the engine to work properly at the altitude you're
To get lots of reliable power from a Gasoline or Diesel engine at
higher altitudes requires forced intake induction - either a
turbocharger or a supercharger. Either one will work, all it does is
pump in more air so the engine is effectively running at a lower
altitude. Much lower, like several hundred feet below sea level. So
low that the computer might run out of fuel management 'map' data, so
you may have to modify the computer program with a chip, or add an
enrichment injector that kicks in when the manifold pressure boost
There are advantages and drawbacks to both types of blower systems
that would take pages to explain. Search around - Toyota Racing
Development has sold both kinds of kits engineered for various cars,
and there are aftermarket companies like Paxton. And if you are
starting out from Sacramento CA, you should be very sure that the
system you choose has a proper CARB Exemption Number and comes with
the proper paperwork, so you can get your car passed by the smog check
inspector and registered again after the modifications.
This can be a DIY job that is complex but fairly straightforward
/IF/ you buy a pre-engineered system kit and follow the instructions
to the letter. Otherwise it can be a very expensive learning curve -
as in, you'll most likely blow up a few expensive engines (for real)
before you figure it all out on your own. The setup doesn't have to
be off by much at all, and you'll start melting holes in pistons or
sending others out through the bottom of the crankcase or out the side
of the block...
And if you add a supercharger to the engine don't forget that the
cooling system has to be up to the task also - you're producing big
sea-level power now, and the radiator has to be able to get rid of all
that excess heat into the thinner air you're really driving through.
