Yes you can easily fit a bit char-g motor in a zz but.....you will have to solder the resistors on your zz pcb board for the energy to bypass the pcb. the 2.6 is faster than NOS, 2.2 can be about is fast or slower than nos with the right gearing, 1.0 is way slow, the 3.0 is just extremely fast compared to NOS, and the 3.8 make the NOS look like a slug. I hope i was of assistance.

Thanks,
