    Hello, I own one of each, but can anyone really explain (if any) the differences between a GT5 and PK80 Engine? Thanks, Steve

    Different, piston. crank and cylinder.

    The wrist pin hole on a GT 5 piston is higher up than a PK 80.
    The wrist pin is shorter on a GT 5

    The GT 5 cylinder is slightly shorter and has different port shapes.

    Is there any real world advantages of one over the other?
