What pinion gear should I use on the Kyosho Mini-Z MR-04/EVO2?

It depends on your motor and the track. Racers in the 1/24-1/28 2WD touring/gt class run a 6–14 tooth pinion in most setups, usually on a 53T spur for a final drive ratio near 5.30. Hotter motors (lower turns, higher Kv) take a smaller pinion; tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Mini-Z MR-04/EVO2 selected.

What is the internal ratio (transmission ratio) of the Kyosho Mini-Z MR-04/EVO2?

The Mini-Z MR-04/EVO2 has an internal ratio of 1:1. Final drive ratio = spur ÷ pinion × 1. With the stock 44T spur, a 4T pinion gives an FDR of 11.00 and a 16T gives 2.75.

How many teeth is the stock spur gear on the Kyosho Mini-Z MR-04/EVO2?

44 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
