Yeah, the NT18 comes with a 0.8cc/0.05ci engine - 1/3 the size of the Traxxas 2.5. But technically, I would have said any engine could benefit from porting. Although I know for sure that neither my hand nor my eyesight are good enough to work on one that small!
What what? It's 1/5th bigger then the trx 2.5
If you've modified before then it shouldn't be too bad. Are you chaning timing or cutting fangs?
