I wnat to get a new engine for my jato. I was thinking of getting the O.S. .18 TM. Is this engine more powerful and more reliable than the TRX 2.5? Also I heard that it needs mods to fit, but I read that it just drops right in to the revo/t-maxx. So would it fit just fine or what kind of mods would I need to do to it? Also should I get the one with the revo or t-maxx manifold?
