it really depends on the piston...look at the SRT4, they have cast pistons and can take 500 HP and 20+psi...just because its cast doesnt make it weak, its more a question of how beefy the ring lands are, like I said, rods are 1st and foremost the weakest part of most turboed motors(unless they have junky pistons with weak ring lands) as for how my car looks....heh, someday I'll make it pretty, right now I'll settle for decently quick
