    Hi all rather curious about this one , done loads of searches but cant find a definitive answer

    would just like to know what are the mechanical differences between the 210amk and the later 225bam engines, most threads seem to indicate its purely a different map and thats all can anyone in the know confirm this theory ??

    it must be a little difference in the map, since when you get a remap, AMK and BAM have the same figures.

    If im not wrong, when audi first launched the TT 225Q, they wanted to be distinguished (is that a word? lol), so they made it have a little more power than the S3 of the time (1999-2000-2001) and thats all. So they gave the TT another map and 15 extra bhp. After the TT had made its place in the car market, S3 and TT had the same engine and same map (2002-2003).

    Yes that's my understanding too; Audi wanted the TT to have the more powerful engine which is why the S3 initially kept the 210bhp unit. I'm also not clear what the differences between the various iterations of the 210 vs 225 1.8T though. Can anyone clarify this? I think I read somewhere that the BAM has variable valve timing too?

    Mechanically AMK and BAM are the same... VVT, no SAI, wideband lambda, EGT probe.... biggest change was APY to AMK... chances are Audi would have retained the AMK code if it hadn't decided to up the power to 225

    Thanks for the clarity Tufty. I thought VVT was in there somewhere.

    so the only difference is the stamp for the engine code then ?

    Ok, yes and no.... mechanically and spec wise then yes they are the same... there are of course subtle differences which make no difference to the performance but are a result of Audi using up the parts bin for the change over to facelift S3's...

    One example of this is the bevel box bracket... an AMK S3 (Dane's) that is in for rods has a cast alloy bracket supporting the bevel box to the engine block whereas mine (also an AMK) has a pressed steel one... there will also be revisions to parts that change slightly over the years such as later version coil packs and stuff... depends where you want to go with it all...

    At the end of the day, AMK and BAM map up the same... there is no compelling reason to choose BAM over AMK and vice versa other than BAM are in newer S3's... if you can afford to buy a newer S3 you will get a BAM, go for a changeover facelift and you get an AMK...

    Same internals, same head... the earlier AMK's had the drillings for the SAI blocked with steel ball bearings as heads were being used up but are still the same small port head the BAM have (and the APY for that matter).

    The differences are minimal and largely academic

    Sorry to piggy back onto this thread but...

    Does anyone know if an APY will map to the same power as an AMK/BAM?

    Thanks in advance

    VAG 20v heads come in small port and large port flavours... check my build thread for some info on the differences... I now run a large port head as its better suited for higher power from larger turbo's

    210ps std same as the AMK... BAM is 225ps (note ps not bhp) (edit... and yes as Welly says below they will map to similar power)

    Around or about page 12, and then a skip to page 14 should sort you with head info.
