2.3 question

Only different part in the bottom end is the piston, which is a low compression forged unit in the turbo motors. Cranks and rods are identical. Personally, IMHO, the stronger block thing is a myth. Heads use a different exhuast valve, and an open chamber, versus the closed chamber in the N/A unit. With slight modification to the chamber to increase volume, the N/A head can be used on the turbo motor. No strength difference between the two.
