What do you all think of this parts list?
Little background on the car: got it from a friend of mine that no longer had the time or money to work on the car. Had a blown transmission and sat for several years. Supposedly has a built rotating assembly in the LQ9. Has the stock 98 heads, stock 98 cam, stock drivetrain except for the 3.73 gears. Not sure on the compression. Asked him and he said its supposed to have 8.5:1. Finally got it running pretty good except for the second transmission is now having some problems. Figured this would be a great time to start creating a build sheet for it.
Current setup is in my sig: 6.0L LQ9 iron block, forged rotating assembly, 408cid, stock 98 heads () with stock valvetrain, LS6 intake w/ stock TB and 60# injectors, TTi T76 street kit.
Goals for the car (eventually) would be to have a nice streetable 650 - 700 HP with about 10 - 15 pounds of boost. This is not a daily driver...more or less a weekend warrior.
New Build:
So is that a good start? Just wanted to make sure that I've got a good list of matched parts. Still new to the turbo world. Thinking I might have to get bigger injectors once I turn the boost up, and possibly ditch the racetronixs fuel system with some external pumps. What do you all think?

I wish I had welding skills too...
If the money is right, I'll probably pick up a welder and start practicing for my build. More than likely I'm going to take most of my pieces that need welding to a local shop.

Just got your e-mail. Thanks for the information. I had no idea that a GT-91 at 15 psi would be at 1K HP. Is that still on a T4 frame, or is it a T6? Trying to figure out how much room I'll need to make up front for the turbo.

While I have the heads off, should I go ahead and get some new lifters too? What would be good ones for the EPP cam?
Thanks again everyone for there suggestions.
