I have rebuilt or swapped engines 5 times.

I keep the alternator, power steering pump, starter motor, idler pulleys, SAI pump (and a/c) unless there is a specific problem or concern. Check the bearings for noise or rough feel and replace as needed.

I replace the water pump, t-stat, AOS, and oil cooler.

If the fuel injectors haven't been professionally cleaned and calibrated, now is the time to do so.

Flush the cooling system.

Inspect all of the vacuum lines and the AOS line that snakes across the top of the engine. Replace anything that looks or feels suspect.

New plugs, fuel filter, air filter, oil/oil filter, etc.

The car should be reliable for quite some time.
