    The LS crank has a longer stroke than the GSR crank which will in turn give you a little more torque. Ive heard of an LS crank in a GSR block, in which you have to plug the oil squirters and bend them out of the way just a little, but not the otherway around.

    I would stick with the LS crank. That's why an LS/VTEC can make more torque then a standard GS-R engine, the longer stroke...

    What ever you do....Don't be a foolish, lazy tuner and not micro polish the crank or think its okay to put any bearing in there you want. Smart thing is to balance it down there to the best of your abilities. Or suffer a spun bearing/blown motor before it even breaks in.

    p30 pistons are best, they bump your compression 20 11:1-11.5:1 perfect for 91-94 pump gas.....with a good tune of course.

    shoot peen is a machining process that strengthens the rods. Not as good as reputable aftermarket rods but stronger then just plain LS rods.
