are these two crank the same? looking to get my ls to rev to at least 8k and was told that i would need to replace my crank also?

 

They are not the same, I believe that the LS has a longer stroke.

true..

ls=89mm
gsr=87mm

and to get your ls to rev to 8k you need an ecu, capable valvetrain and arp rodbolts and headstuds to be safe

you dont need to replace your crank

 

would replacing my crank do any good or bad?

yes, i am replacing my rod, piston, and valve train.

i have hondata and its turbocharged.
