What's the difference between a tC and SRT4 motor?

Why can the srt4 hold so much more boost even though they are both 2.4L?

    The Scion tC is not turbocharged. It is a naturally aspirated engine.

    Only the SRT4 (both the Neon and Caliber versions) is factory turbocharged.

    Thicker cylinder walls,

    stronger crankshaft

    forged rods,

    forged pistons

    Larger cylinder head bolts/studs

    About the only thing these engines have in common is the number of cylinders. Completely different engines built by completely different manufactures.

    I don't know for sure but I have dome opinions. Maybe the SRT4 has a stronger crankshaft, connecting rods, and pistions. It may also have a lower compression ratio allowing it to accept more boost.
