    In my honest opinion, if you are going to get forged pistons you may as well get the insurance of stronger rods.

    This may be a silly question but why are you swapping out the pistons. If they need to replaced of course go for it but if not id invest the money elsewhere.

    Rods are cheaper than pistons in most cases LOL.. So I'd suggest doing it all to stock format. I personally did CP pistons with Manley H beam rods.

    Depending on the power you plan on making Manley H beam "economy" rods are great, decent price and will support 700hp all day. I've got a few friends who run them in their daily drivers, myself included... But for mad power the I beams are around $800 and support well over 1000hp. And for pistons CP is the best IMO.

    i do know manley rods are a good choice but what do you think about the eagle rods, and yea if your doing the pistons then you should get rods as well.

    If you're planning on using these in your 2G, you'd actually be better off using stronger rods with the stock pistons as the pistons are definitely NOT the weak link on that engine.

    IMO. Take it as you will - but the shop I work for only suggests manley due to the fact they are lighter more balanced & come with a better finishing machining wise of the eagles plus gives a more precise balance!... Eagles are forged were as manley are actual billet steel. manley hold more power for a longer time. yea you can say you hit over 800hp with eagle H beam "but for how long?". . Manley H beams - all day

    What shop do you work for? Agreed on all points except one. The Eagle and Manley are both forged. The Manley H beam is not billet. Even the Manley and Oliver I-beams which are advertised as billet are not. It's all marketing.


    To the OP, think about saving some more $$ and getting a set of Manley or Eagle rods to go with the pistons. If you're pushing the limits of the stock pistons, or plan to in the future, you will appreciate the increased reliability of a set of good rods.

    I'm going to disagree with you on CP pistons being the best (for a 4G63 at least).

    Have you ever read this thread?

    To the OP, if you're only planning on running 15psi don't even waste your time with forged pistons. Buy a set of NPR cheapo OEM replacements off eBay or parts dinosaur and do a standard stock rebuild. The stock sh** is going to put up with whatever you throw at it with only 15psi of boost. Or see if you can find a decent stock bottom end 6 bolt for cheap and swap it in.

    Sorry for the noob question, but does this mean that you can slap an
    FP 68HTA turbo on your DSM and keep it at/below 15psi without putting forged pistons, rods, etc. on?

    You absolutely could. Stock internals are extremely strong, I can't think of a single turbo that could surpass the limits of the stock engine's rods and pistons at 15psi, LOL.
