Euro M52 and US M52, difference?

[EddyTeddy]

Any difference between Euro M52, and US M52? Planning to fit M3 cams in Euro M52, but some said that I can only with cams from US M3, and will US M3 cams fit?

I don't think the euro and US M52 are any different, but it's not really related to your problem anyway. From what I read, this is what you need to know: the euro M3 engines are different from the US M3 engines. The US M3 engines are closer related to the non-M engines, while the euro M3 engines use more specialized components. Therefore the US M3 S52 cams will simply drop into the M52 engine but the euro M3 cams will not.

So the reason you need US M3 cams is not that the non-M versions are different in the US and in europe, but that the M versions are different.

they will fit, internally they are identical. the only real differences are the external emission related parts.

The Euro M52 suffer the nikasil (http://www.usautoparts.net/bmw/engines/nikasil.htm) problem.

This is a problem just in america because of the high amount of sulfur on the gasoline.

No, it's a problem everywhere. Plenty of people in Europe had issues with the nikasil engines.

perhaps but that really doesn't have an effect on his use of an American market S52 cam.

Yeah the S52 cam is fine in the "euro" M52's people do that mod over here in Australia as well with no issues.
