Wow that sounds almost exactly what I just traded for a buggy, but I ran an integy Chasis and ended up with a p2 engine.....that was the best setup I had for a maxx....oh yeah get the 1/8 scale diff version of those bulkless system......especially if your gonna throw a sirio in it like that monster....you will eat gears daily......and don't forget the tranny upgrades too....oh boy this makes me want to make another Sick maxx....miss mine now damn.....that sirio will blow your mind in that thing too.....enjoy it...
