Default question on forced induction

what has to be done to a motor to make sure it can handle the horsepower from turbo charging? Like if one wants 700hp, what would the motor have to have done to it from its stock LS1 form?

Rods and pistons for starters. Some like to go with the iron blocks too.

Some agree that the stock crankshaft will hold, while others don't see the need in chancing it. But forged rods and lower compression (another debateable topic) forged pistons are the first things that come to mind.

without having to watch things constantly, pistons and rod bolts minimum. Preferably rods too.

studs are nice, but probably not required at that level.

FWIW, i ran the stock crank to 170 MPH traps. Doable, but not recommended.

There are many upgrades that can be made to help the life of your motor. I personally switched over to an iron block, but that isn't a must. You are most likely going to want to lower your compression. You can purchase new pistons and stronger rods. You could also have the block or heads o-ringed.

EDIT __ You guys type to fast... all the replies were within a minute of each other. I just thought I would point that out.... you know, so I don't look like a jackass who just repeated everything that you guys said. (harlan, I know what you are thinking...don't say it)
