As for oil, a good Racing Synthetic, such as JR1, HPL , Red Line.
If your bearing clearances allow, use a 5/20 or 5/30 weight. The lighter weight returns to the pan quicker and disperses air bubbles quicker as well. Also the lighter oil may protect better than a heavier oil that could be compromised with aeration.
And... WIX Racing or Moroso Oil Filters
My 2 cents.

I use Mobile One 0-20 Weight
Not road racing and figure wears engine less with all the cold starting.
