    Its compression ratio. The 3rz has balance shafts where the 2rz doesn't, also.

    Yes, the 3rz has a higher ratio. 9.5:1 vs 9:1. IIRC. Someone will correct me if I am wrong on the ratio numbers.

    There is only about a 10hp/20ftlb torque difference between the motors.

    You could get a set of headers and do the deck plate mod to gain about that, if not a little more.

    Not as many as the 98..
    Pretty sure the 3rz has forged rods as well...
