kit K590M84 10.3 comp ratio for N/A BP engines
has all rings, pins, clips, oil rings, wrist pins all look good quality but-
wrist pin/gudgeon pin retaining clips are bad design ( these are not spirolox type ), horseshoe shape round section with no loops on ends makes fitting them impossible without scratching up piston.
is it just me or would a square section clip & groove with proper circlips with loops that can be inserted/removed with circlip pliers be too much to ask of a QUALITY piston.
pistons are for miata/protege as listed BUT-
piston has narrow skirt that hits oil jet/squirter directly, bending jet to clear will result in jet then contacting rod, poor design very badly designed, cnat believe such a product could be made so wrong.
still looking for solution to this problem, do not want to remove pistons from rods to have them machined, neither do i want to block oil jets, modifying jets may not work as they will end up hitting rods if you change position?.
overall- these do not work out of the box making them next to useless, the money you spend getting them machined/balanced to actually work would be better spent just buying a better piston in the first place
