    Engine rebuild advice needed: Please analyze my list ('04 GTX S/C)

    My 04' GTX S/C spit the chain and wrecked a few exhaust valves so I have the engine out and on the stand to repair. I figure I might as well rebuild it to handle some future modding (more boost, etc). I am not looking to turn it into a racing ski but would like to hear your opinions on the parts below. I am on a limited budget for this project so I cannot afford rods, cam, crank, etc. Please let me know if anything looks overkill or not worth doing since I am using mostly stock internals. In other words, I don't want to spend an extra $300 on ARP fasteners if it is pointless on factory internals.

    2010 RXP Pistons
    2009 Valves
    IWIS Timing Chain
    ARP Head Stud Kit
    ARP Rocker Shaft Bolts
    ARP Flywheel Bolts
    ARP Rod Bolts
    Stock Crank
    Stock Flywheel
    Stock Cam
    Stock Rods

    Would this setup be a bit better than stock and handle a few extra pounds of boost if I should choose to head that direction in the future or should I leave it alone and run all stock stuff?

    Thanks,
    Chris

    IMO drop arp rod, rocker bolts and add upgraded valve springs and retainers
    may need cp pistons if bore is oversized

    Thanks Chris. Bore and pistons are stock and in good condition to my knowledge (and visual inspection) so far. The ski only has 59 hours on it. Going to split the cases in a day or two to see what's going on downstairs.

    Do you have any suggestions on valve springs and retainers?

    bro you have to change the rod bolts anyway because the stockers are tty. arp all the way the stock rods are fine but not the stock bolts. you also have to change the rocker bolts as well tty when you put the updated valves in their 40.00, arp rod bolts 70.00 absolutley dont cheap out on these two items.

    Ski is right you put the arp rod bolts on stock rods get ready to take a course in strech gauge procedures. IMO seadoo rod bolts are awesome with there stock rods and the seadoo rocker bolts I'm running personally.

    I agree and have run ARP's in some of my street cars but I am not liking the sounds of "stretch gauge procedures" (whatever that means) at this point.
