    If you have a side elevation picture of the pistons I can tell you how strong they are likely to be.

    I assume you are talking about CP 5efe Forged pistons?

    The same is true for both stock and aftermarket pistons. Except for the 5E-FHE pistons. I am yet to find an aftermarket one of those.

    Piston on the left.



    1st Ring land is a reasonable distance away from the crown.

    If you want a better side elevation pic, let me know and I'll try to find one.

    Rep points are for those who feel inadequate in other areas !

    Crown thickness and ringlands look really good, however those valve reliefs aren't so good. Those are likely to be the weak points if you get it into a lean condition. I'd say the margin may be a little slim for the HP you're chasing.

    For that HP, I'd assume you are looking at decent rods as well? Those stock rods look terrible - they'll banana no question at all.

    The stock 5E-HFE rods are stronger than the 4E-FTE rods which are good for a decent amount of power.

    Maybe, but not 100+hp per rod.

    No, but remember it is a 1.5L engine.
    The HFE rods can get decent numbers for a engine of that capacity.
