When considering the two models - even though the larger version has more HP - some of that power will be lost with the fuel soaking DPF muffler - all in all the best bet is the 2650 you get a clean engine (new 4 cylinder) and you have $5k for fuel or goodies to hang on the beast. I have a B21 and while it does not have ton's of power, its fine and will dig like crazy.
