    There isn't enough meat to bore the cylinders.

    Any sort of failure = new short block. Or sleeves with new pistons etc. Then you're also looking at a custom tune, because the engine is now 2.7l.
    It all adds up really really fast. Just cheaper alternatives to make more power with.

    I think that's why most of the guys chasing numbers etc. Have jumped ship

    Well my another block is already ready.
    Sleeved with cast iron 2mm cylinders.
    Pistons 82.5mm with same stroke.CR 9.5:1
    New engine size now will be 2.85L.
    You are totally right, there is no way to make this engine a stroker. Well, time will show how its will work. Hope to push ~40psi boost(overpressure) to this engine. Only the reason i follow this way/this engine is the cost of another engine was very cheap and sleeving is cheap operation in my country.
    Forged pistons and rods wasnt a huge deal too.
