hpi firestorm is a good competitor for th e 3.3 jato. exept the firestorm is a single speed, and the jato is a 2 speed. the firestorm will leave the jato off the line, but when jato shifts, its all over! maybe just get a jato, and put a bigger motor in it. search for a beatup, burned up jato, and fix it and beat the snott outa that stocker your friends got!HA! I dont know what other motor fit, but I want to do this to my 2.5 jato. my friend has a 3.3 jato, and I can keep up on corners, but on the straights, he hammers me
