Which engine can make more power: RB26DETT or 2JZ-GTE?

Both can exceed 1,500 HP with proper building. The 2JZ-GTE has a slight advantage in factory internal strength (closed-deck block) but the RB26DETT has more aftermarket support for time attack and circuit racing. At stock internals, both typically handle 600-700 HP on pump gas with supporting modifications.
