What are the differences between the BAM cylinder head and the ARX head? Is the compression ratio different? Any other differences?

As far as I know there isnt a difference. Pretty sure the ARX has VVT as does the BAM.

I didn't think there was either but they do have different partnumbers, although the camshafts have the same number.

Do you have the part numbers to hand?

The only partnumbers I have I've got from ETOS, the ARX head is 06A 103 351 L, the BAM head is 06A 103 351 J.

Its just that there is a BAM head and camshafts on eBay at the moment and I'm toying with the idea of a BAM conversion to my ARX.

Wanting to get some parts together first really.

You would be better off getting a complete BAM engine wouldnt you?

You're probably right about that, especially at that price, its just that I saw it and wondered what the diffences are. You don't see the heads very often on their own though. I know there are alot of other bits needed to go with it.

Is there something wrong with yours or are you considering the full six speed and k04 conversion anyhow?

Nothing wrong with mine, just thinking about K04 conversion. Not sure about six speed though, would it be needed or just desirable?

If your just thinking of a K04 conversion doing an engine swap is the long way around. Also there are better turbos to use than the K04.

Wanted to keep OEM really, I know there is alot of 'discussion' as to which turbo to use. Was hoping to get inlet & exhaust manifolds, K04, injectors, fuel pump, Miltek, FMIC and remap and be happy with that.
