overboring

  1. Overboring a 1.6 156

    Alfa 147, 156 & GT
    This is just out of curiosity, but how much can you overbore a 1.6 engine? Is it possible to fit the gazzella piston which are 83.5mm diameter? http://www.gazzella.cc/cart.php?target=product&action=view&product_id=16891&category_id=515
