realistically, how long should a 2JZ-GTE last? i've been hearing alot of people having low compression numbers and such even with just BPU. these are people that change the oil with synthetic regularly and pretty much a well maintained car. then there are people with singles that are tuned by a reputable tuner with proper fuel/aem, maintained well, and still end up with low compression numbers. makes me wonder how long a 1000 horsepower supra would last even with just the occasional 1000 hp pull... what are your opinions? tips on making the engine last longer?
