im getting a new nitro motor but i need to see if a .21 or.18 engine will fit in where my .12 used to be and what is the best motor for on-road in your opinion\
thanks for any help

Honestly you dont need a .21 or a .18 in it, you can get a decent .12 for about 200-300 and they are plenty fast if not you can get a O.S .15
not sure what the model of the engine is but its pretty fast

An O.S. 18TZ will fit and it's ballistic. Of course you won't be able to race with it because the engine is too big for the regs, but it'll be a lot of fun bashing! It won't rev much more than the .12 engines, so if you want to get more performance out of it, you'll have to gear it up.
