I do know that I drive torque, while listening to my friends prattle on about horsepower.
Well a newer engine will definitely have more potential. Just depends on what you want to spend. That's the nice thing about the AAZ. Aside from the 1.6TD, it's the cheapest engine to get the most out of. A guy on tdiclub is building a 450 hp tdi based on CR shortblock with a VE pump but the costs are something I could never justify, at least not to my wife .My favourite engine is still the AAZ just because I don't have to go to a tuner to get the most out of it.
