Edit: to WoW:

7MGTE runs to about 6500 rpm stock, 1JZGTE to 7000 rpm. Not a huge difference. But how they rev up is astoundingly different. 1JZ just wants to GO! Looking at other things, the 1JZ is choked by what are probably the worst factory turbo manifolds ever made. It looks very much like it was choked deliberately to limit it to the 280 PS limit.

Now when comparing built motors, with a better manifold/turbos and cams, a 1JZ motor with stock rods, stock head will spin easily to over 8000 rpm. Drag racing 2JZ's with an 86mm stroke have been hitting the 9k range (built bottom too, though, and due to more development here).

In the case of my buddy's ridiculous 7MGTE (1015 whp) with Cunningham titanium rods, and a heavily ported head, knife-edged crank, plus custom cams (280 degree range), its hard rev limit is set to 7600 rpm for reliability.

I imagine a properly built 1JZGTE could actually make equally reliable power up to 9.5-10K rpm. Of course being smaller displacement, it would need the extra revs to match the power, or more boost.
