95ZN1W3 vs. 95ZN1W4 and help locating pistons
folks;
i'm trying to determine the difference between these 2 cylinders. 95ZN1 W4 is in the foreground while the W3 is in the background. i was told by the PO that the cutaway W4 was an early after market attempt at improving case "windage" (...not sure that was the term he used, but i think you get the idea) i have several W4 units and 1 W3 and the only difference i see is the obvious one as pictured here. is there more to the story ? also, trying to source 3 usable 95MM pistons. Mahle # 95P30 i've already tried EBS & the wanted / FS board here. any help appreciated. thanks! jerry ![]() ![]() ![]() |
