2JZ GTE is the stronger motor. Most statements beyond that come down to subjective preference regarding what you’re trying to accomplish with the platform. A fully closed deck iron short block, one of the beefiest cranks ever put in an OE car. It’s a dyno queen motor and the power curve sucks for real life driving…but it’s so beast.
N54s are no wall flowers though. For an open deck it’s shocking how much power they take on a completely stock block. We’ve cleared 700WHP on stock rods, pistons, crank, etc etc. That’s incredible for a high compression 3.0 Liter 6. And the ST power curve is still usable in the real world.
