Does anyone know if 528e is the same as the 525e? I am looking at a teflon coated lightwight piston set with sealed rings and they are in the staes advertised for a 528e/325e/325i i am hoping they will fit my 2.7 m20 engine that came out of a 425e e28?
Does anyone know what sort of gain you are looking at if you use lightweight pistns and sealed rings?
