when you say compression quality do you mean all teh force due to teh sloping top design is forced outwards to teh rings under compression whereas with a flatter top teh forces are retained more centrally on teh piston, would think it creates a funny burn pattern too,, mind you 185 hp froma 1.6 aint bad, but this is probably more to do with teh head and camshaft designs..
so you rate the integra piston over teh EK9 piston then?
if you were going to build a B18 would you go this route or just get a B18 C5 or C6 and drop the whole lot in from a low mileage integra?
