Good thing about a 2jz is that it has 2 turbos, so you dont have to worry about driving off boost, unless you want to save fuel, then you can do that too. It makes 300ft lbs if not more, sure a 2jz expert will jump in here. You drive like an old fart, i bet turbos hate you for trying to keep the engine rpm's too low, which result in turbo rpm's going up. 6500rpm? What the fuck is that weak ass shit? 7000 is where its at.
