im a little confused as to which motors are supposed to have the greatest top end speed.
my new fairlady(stock orange gears) runs faster w/ its stock 2.2 motor(yellowish-green cap) than w/ my microsizers 2.6 motor(orange cap).
i also noticed that my bitchar-gmotors 1.6 motor(blue cap) seemed to be faster than the stock 2.2 in one of my other cars.
do motors "age" and get worse with time?
or does the stock gearing put too much of a load on the higher numbered motors to get optimum top speed from them?
or do i have things all mixed up here?
