Hello, I have been on this forum before but I forgot my username so I created a new account. I have an xtm xt2 buggy and the only place i drive it is a local track. I have come to the conclusion that this is not a track buggy. It seems real slugish when compared to the other buggies at the track. Instead of buying a new buggy I figure i will just upgrade this one and I want to start with the engine. My buggy has a 24.7 engine currently. I don't know whether I should get a smaller engine or a bigger one but i want more TORQUE!!! These buggies at my local track freakn scream and have so much torque!!! No matter how good i tune mine it will not sound or perform like those other buggies so i need some help. I would also like to get a few more laps out a tank of gas. So do i go bigger or smaller? Also, what are some good brand engines? I know i will need several other upgrades to be able to compete but I would like to start with the engine...Thanks...
