Ok so I just bought a set of these rockers and I have a few questions. Right now I have SD headers, an Overkill pcm, no cat, and a performance cat back exhaust. With these comp cam 1.9 roller rockers what will I see for gains? And can I run my current pcm till I'm ready to tune?

You can run your current PCM file without a problem. The only thing is you might want to get someone to adjust your car to shift a little higher.

I would get some springs and modified retainers along with new valve seals for when you put those rockers on though.
 


Really none of you can help? What should I get for this install? I want top of the line parts so I can have piece of mind. And if possible the strongest parts that will compliment a turbo setup.

I've heard a lot of turbo guys say, 130# is the only way to go. I don't have actual experience and never looked into a turbo setup which is why I was being quiet.
 


I've heard that 1.9 can compliment a turbo setup very well. Cams are a big job and I also got these cause I got them used off a guy on here (very nice condition too) cheaper price. I don't have boat loads of cash.

You want enough to prevent float for the life of the spring, but not too much otherwise its unneeded stress on your timing/valvetrain/seats.
 
Go with an LS6 if you don't want to change the timing chain. If you go turbo and get float, then change the springs and timing chain at that point.

1.9's do compliment a turbo nicely. However to use them, you want springs, retainers, reusable bolts and valve seals.
