wanna see what ebay pistons look like?

[Bumpysbro]

i ordered a kit from them last year and i recieved the wrong water pump for my b6 so just a heads up. oh and another member i think "shades" found out that the High volume oil pumps are just stock oil pumps with the label grinded off. those pistons look identical to the stock pistons that came with my kit.

if you ordered your kit through Importperformanceparts.net the oil pump case would be the same as a OEM but with the HV internals... So to avoid confusion they shaved off the lables and stamped HV in red ink. Yeah the pistons look identical as the oem ones. By the way, do you guys know the CR for the stock 1.6L pistons? I heard that miata ones are a little higher CR, is that true? I can't find this info anywhere
