The idle brain comes up with many strange ideas, But they are worth
discussing:

Watch out for vacuum ( lack of it ) problems in the turbo versions,
since the manifold can be positively pressurized a lot during
spirited driving. Perhaps a large accumulator ?

Frank  Deutschmann mantioned ( June or so ) that he was considering eliinating the hydraulic pump, hoping to save 60 or so HP.
Before I rebuilt mine, I considered getting
an ELECTRICAL 12 VOLT PUMP, with a cutoff switch and a pressure
accumulator. It would take the constant one or two horsepower
load off the engine and put it onto the battery. This pump would
only run when the pressure in the accumulator fell below
2000 PSI. I can get manufacturers names if anyone wants.

If you replaced the brake booster, how would you replace the
steering system need for high pressure mineral oil.

Now regarding the BURNT HEADLIGHT WARNING INDICATOR,

The lamp warning in my '86 is triggered by an UNBALANCED
CURRENT in the lamp circuits. If BOTH BULBS are fused,
or disconnected,  you will get no warning indicator from the
autocheck system.

I have put in a headlamp relay and have had no problems
with the autocheck complaining, both sockets are " OPEN "
as it were. THIS MAY NOT APPLY TO NEW ( after '86 ) SYSTEMS.
