Ls Crank Problem

[lsvtec hatch00]

i was wondering if there is anything i can do to my ls crank to strengthen it. i have an lsvtec with itr rods but i want a stronger crank for higher revs. how much would it cost?

your crank should be ok, to withstand higher revs get arp rod bolts and a z10 girdle.
