Sure, go on ahead with the info on the PCV system I'm more than willing to learn! I was thinking of a master power T70 to start off with since I'm trying to make this a budget build to start off with untill I build the big motor and spend big money on a good turbo. Which trim should I go with, they have P and Q trim and also what A/R?

The best way to setup a PCV system for boost is to swap in an LS6 valley plate. Once done, all you have to do is tie the valley plate into the intake manifold with an inline check valve and put filters on the valve cover ports. If your engine is not in the car this would be the best route. If the engine is in the car, you can use switch valves triggered by a pressure switch to vent the crankcase to atmo during boost. I'll have to draw up a diagram for it so if you'd like to see it, let me know cuz I don't have one drawn up. Oh, and here's the LS6 valley plate info

I'll go ahead and do the LS6 valley plate since the motor is still out the car, since thats the best way. Any opinions on a MPT70, P trim, .68 A/R? Said to be good for 700hp so that sounds right up my alley. Once again, I greatly appreciate the help!

I'm not too familiar with MP turbos but there is a guy on here that knows everthing about them. I think "KBracing" is his screen name and I believe he is a MP turbo dealer. A .68 A/R sounds good for a 4.8L tho. As for the LS6 valley plate, make damn sure you use an inline check valve between the valley plate and the manifold. It will prevent boost pressure from pressurizing the crankcase which is VERY bad with a turbo setup.

As far as check valves is there any better than others? I found the info on that turbo that I was needing and it made around the power I am looking for at a certian amount of boost so I think I'm going to try it out.

When it comes to little parts like check valves, I always get a migraine trying to find what I'm looking for. That said, there aren't any "good" check valves that I know of. I just use whatever I can find that will suffice. The only place I know of off the top of my head that sells check valves for PCV systems is STS. Be careful tho, STS has some TERRIBLE customer service.

A MP T70 with .68 a/r would be right on the money with a boosted 4.8 and LS6 cam
