    This was the last mod I did to my LS2 and the engine gained torque from bottom to top of rev range with a max gain of around 20N.M at around 4500rpm.
    There was only around 3-5kw gain in horsepower but it was the torque that was the telling part.

    If you could pick up some 243's cheap maybe but why not just get some Higgins CNC'd 241's exchange.
    I've got Higgins 243's on my senator and combined with the Fast102 gave the car a real nice torque kick which is fine when running 4 spd auto.

    What happened to not spending money on it? Didn't last long lol
    How many kms has it done?

    243's are better than 241's but Higgins 241's are better than standard 243's....
