What's the difference between 1JZ-GTE and 2JZ-GTE?

The 1JZ-GTE is 2.5L (86mm bore x 71.5mm stroke, oversquare) and makes slightly less torque but revs faster. The 2JZ-GTE is 3.0L (86mm bore x 86mm stroke, square) with more displacement and torque. Both are cast iron blocks with aluminum heads. The 1JZ is preferred for drifting; the 2JZ for drag racing and high-HP builds.
