ORIGINAL: Traxxassss fast!!!
Yeah i'm thinking leave the 2.5 in,i mean why put a 3.3? It goes just as fast but doesn't keep up due to the 3.3 over powering it with torque.Lets face it all the 3.3 is the same block same block different..So to to the slighty larger 3.3,2 dfferencas,(1) larger bore ((and stroke).Mine with the 2.5 can spin around on black top,on 3 wheels.
Well then, in this case I guess if it ain't broke, don't fix it; I mean I guess if the 2.5 suits u perfectly fine and it still runs and performs good enough for ya, then why spend the $ to upgrade to the 3.3? I mean that is unless u really do at some point change ur mind and do want a little more power....at that point I would say go for it; but for now, just stick with what u have...
