E30 325i / M325

Hi folks,

In relation to these cars, my question is regarding cylinder head covers - is the colour difference in the following two pictures of any significance? Undoubtedly a dumb question, I know - is the black one simply a shroud? Cheers.

black ones been painted. There might be a couple of oddball cars (hi-comp/alpina mods etc) out there but generally no engine difference between M325i or 325i

pretty sure one is black and the other is silver.

^lol smart as.. as said one is just painted. highly unlikely that there is any difference in the motor specs. a m20b25 is a m20b25, its the same motor in the m325i no difference than a normal one.

Fair enought, cheers for the response. Was just curious as 325i engines seem to fall into one of either category, and I didn't know if the 'black top' was a later iteration. From what I can see the M325s I've seen (e.g. on trademe) all sport the 'black top' - was it a factory option as part of the M pack perhaps? The only M325 I've seen with the 'grey top' (heh) was one which had cylinder head work done.
