    It's tuned for 10-11 psi
    It runs alittle rich, but i rather have a bit rich then leaned out

    I was thinking like some rods or something to stregthen the motor. Read some people saying they wouldn't do more then 8psi on a ls but others say 12psi is safe.

    bought this car all ready boosted so i don't know how much abuse it's gone thorugh

    If you bought a boosted car its more than likely took some abuse.

    Ok.

    it's not really faster I want right now, just more security in that the motor will live long and a healthy life.
    could someone give me a run down on some of the stock parts capabilities like pistons, rods, and block.

    And what's the weakest link in the ls engine

    rod bolts are weak

    i would NOT push that engine above 230whp if it is completely stock. possibly even less if it has some mileage on it.

    heres what you should be looking at:
    mild re build (replace pistons and rods with forged stuff, re bearing, re-ring, hone (bore if needed), crank micropolished and new seals/gaskets all throughout the bottom end.

    or

    full build
    re-sleeve, forged pistons and rods, new bearings, seals, gaskets, crank polished, bottom end balanced, etc

    i recommend arp hardware in the bottom end (rod bolts primarily) and certainly head studs if you plan on things lasting longer than a few short pulls.

    sorry for the double post,

    Thinking mild rebuild with some new rods and apr hardware
    can't afford the pistons right now.

    if you cant afford the pistons then just wait until you have the cash saved up for them
    ebay has an eagle rod/je piston combo for 700ish. thats where i got mine from.
