The B20Z makes 146hp @ 6400rpm. If you're going to build the motor for a decent amount of boost, I'd just get your LS resleeved and bore it to 84mm for a 2 liter.

Sure they do, you just have to tune them correctly. There are always going to be people that blow motors and try and blame it on something...almost every time it's because of the tune.
