I am running race ware headaches, ARP rod and main bolts, stock crank and stock main bearings, IE connecting rods and 9:1 cr weisco pistons with my setup and no problems with all the strength I need. I have Gt4094R turbo, 870cc injectors and seimans injectors with 20+PSI of boost. Have not dumped my car yet but with everything else done I am well over 600hp as I had 550 just before upgrading some of my hardware and software. Fairly good prices for the conn rods and pistons, JE has a great setup for the pistons if you want to spend a bit more cash. IE sells a great set FPR a decent price for JE pistons (you choose the CR) and the IE connecting rods. Check out their site. The crankshaft is already stock forged so as long as there is no defects I wouldn't touch it unless you want to shoot for more than 800+ AWHP.
