Put in a 3S-GTE and get the weight BEHIND the front wheels.
Yes, the JZ's are very robust. The JZs and the 3Ss still rank at the top of Toyota's flagship engines. Not saying they're still #1 but they're still hanging with the newcomers. In my opinion the 3S is still yet to be beat (of course it's pretty much a 2JZ with 2 less cylinders). And yes, one could argue that the 2JZ hasn't been beat if for no other reason than because they stopped building i6s.
