As a newbie's old man/mechanic, from what I could make sense of:
- 48 pitch means 48 teeth per inch.
- 64 pitch means 64 teeth per inch.
- The standard gears that come with the Tamiya TA05 are the AV range which are sometimes refrred to as 06 pitch. This means 0.6mm between the teeth. This converts to 42.33 teeth per inch, so it might work with a 48 pitch pinion, but it will almost certainly be very noisey and inefficient.
- The Tamiya optional gears are 04 which means 0.4mm between the teeth. this converts to 63.5 teeth per inch, so this will probably work ok with other 64 pitch pinions.
Check the rollout that the locals are using at your track, ask for their help and. Search the other threads here for locations of various rollout programs/websites. Castle Hill Raceway has a rollout calculator on its website. Your track's web site possibly does too.
The biggest Tamiya AV gear was the 25T which gave a rollout of about 33mm from memory. The locals seem to use around 40mm. I checked out what was available in the Tamiya 04, but that meant I would need the biggest pinion in their range and then I would have no ability to increse the rollout again without going to another setup.
The LHS had 48 pitch gears, so I got 72T spur and 33T pinion for the TA05. I can still easily increase the rollout by about 15% by using a 38T pinion and even if I have to go further, I can change the spur. There is a wide range of bigger and smaller 48 pitch spur gears available.
Now, as for which is better, 48 or 64 pitch? Beats me. The LHS had a limited range in 64.

IIRC my old Tamiya had metric gears - with various pitches. Losi and associated gear that ive acquired since has always been SAE - with various pitches available.

The 64P is also good for cars that need a lot of teeth on the spur, but don't have the room for big spur gears, like the Tamiya 415.
