Default Forging Bottom End?

What all is required? I plan on putting on a D-1SC Procharger later this year, so I'm curious as to what needs to be upgraded if I want to run more than 8lbs. of boost. And maybe a guess on the price too... Thanks

all you need is piston rods and a crank if you just forging a stock motor you can keep the crank cause it will go all the way up to 1000hp by its self but you will also need to upgrade your fuel system your fuel pump and injectors. you also need to get better heads and so on and so on just all the boltons.

Yeah I know I need to upgrade the fuel system.. already planned on doing that. I was just curious on what internals need to be upgraded to run over 8lbs. of boost. So pistons, and rods? Is that all?? What kind should I look into getting and any idea how much they cost?

Thanks

Also some good bolts!
THE RED "BLUR" is right about the factory crank! They see 1000hp before they start to flex, i have never heard of a LS1 crank breaking...yet.

Hmm, alright.. Depending on the price, we'll see if I'm going to do it.. Wasn't planning on it, but I KNOW I'll want to run over 8lbs of boost lol.

Good pistons, rings, and possibley rods. Depending on power level you may be able to reuse your rods, and crank. Reusing the crank can save you a lot of $$$

What kind of pistons/rings/rods should I look into getting? I know I could call Bob @ EPP and ask him, which I will.. but he's not open now and I wanna know what I'm looking at spending before I ask him, in case it's not in my budget.

And if the crank is good up to 1000HP then I won't be upgrading that lol

For a decent set of budget rods: Compstar, Eagle, Scat, K1.

For Pistons: Diamond, Wiseco, Mahle, J&E, probably a couple others.

Keep the stock crank, you'll be fine with it.

Yeah, rods and pistons are all you would need to upgrade. But while you're at it, if you have extra cash, why not stroke it out to a 383?

Figure another thousand bucks for a new crank if you want to go the 383 route.

Oh if you do go to a 383 you'll need a new crank?? And what will stroking to a 383 do, just make more power?

Yea more cubic inches means more power and you'll gain some good torque
