    you will need the ls crank, ls rods and pistons to fit the ls rods.

    You just need proper spelling, punctuation and capitalization. :)

    You shouldn't need any machining outside of standard block rebuild work- everything will drop right in if you get the correct bearing clearances between the crank and the journals in the block.

    LS crank will fit in a GSR block, I've done it. Some machining is necessary.

    LS rod length is a must. You don't need stock LS rods, in fact, I recommend aftermarket because the factory rod bolts are crap past 8k.

    Pistons - Choose any B-series you like. I ran JDM ITR .25 overs and achieved 11.8:1 CR.

    But, you can go bigger if you like.

    Enjoy the extra torque!
