It features a 99.75mm bore and a 79.0mm stroke, designed to work with stock-length rods and a 23mm wrist pin.

Each piston weighs in at 413g, a detail that matters for engine balance and smooth operation at higher RPMs. The 30.7mm compression height and 130.5mm rod length are key measurements that ensure proper fitment and geometry within the EJ25 block.
