    Simply put, there's a set of piston heads up for sale, i'm interested as I'm about to start rebuilding my old engine, yet the buyer is unsure whether FE piston heads will fit the GE. Anyone know?

    Details about the pistons are on the item listing

    3S FE vs 3S GE Internals

    The decks are the same height but the FE pistons are dished and shaped to suit the FE combustion chambers, your current pistons are flat.
    Also the FE pistons are press-fit, GE pistons are not. You may have to "convert" your small ends to press fit.
    FE rods are not an option as they are very skinny and not suited for the extra power and revs.
    Expect to lose compression and power

    Those pistons are an option if you intend "flattening" them and using longer rods, but you'd have to re-cut the valve cutouts as the GE valve angles are a lot steeper and the valves are much closer to the pistons (5mm?).

    If you're after more power it's better to fit higher compression gen2/3 GE pistons. It will work out cheaper, less hassle and work better! ($200 new)
    I also strongly recommend fitting ACL race GTE bearings on all journals, they are waaay better - ask Mafix

    Spot the difference?


    Gen1, Gen2, FE


    GE vs FE head - bigger valves at a steeper angle and less room


    Before you shout "Foul, that's not Gen1!" - here's the gen1 GE head
    Can you see any differences?
