    Hi all, anyone got ideas on how much a new head for the 8L s3 would cost? And any reccomendations on where to look / buy?

    Any help would be much appreciated.

    New heads vary between 700/800 quid to around 1200 from a dealer IIRC... why do you need a new head and do you need a bare one or a fully built one? also which year? as APY (pre facelift) S3's are different to AMK/BAM (facelift)

    Bill @ Badger 5 has some heads kicking around that may be of use...

    Is there any difference between the AEB and AGU large port heads or are they identical?

    Cheers for reply, need a bare head but have heard that you need new valves as once disturbed they tend to go wrong when the heads refitted and engines used. I got a 2001 facelift amk. I d'nt know enough about engines to explain the problem but the car is with Dave Turner in stonehouse, his sons run TRD in stroud, thought you may have heard of them if you live in gloucestershire. But in very simple terms coolant is getting into the head through one of the guides and somewhere else. Its washed one of the pistons clean and one of the spark plugs was corroded quite bad.

    Yeah... have heard of TRD... Bill @ Badger 5 knows them too (also in Stonehouse)...

    You don't need a new head and you can reuse the valves and other running gear too... AGU is large port but if you don't have plans for more than stage 2 power then not much point in fitting one tbh... biggest issue with used heads is valve guide wear in particular exhaust guides... get them checked and replaced as required... AMK's (and maybe BAM's too) seem to suffer more from cracking as they run a little hotter than earlier S3's (APY's)... you can also use heads from the AUM engines too (K03 turbo'd cars like 2001> A3's etc)

    I tend to make a judgement call on which parts look less worn.. Audi's were mostly on variable servicing whereas SEAT's and other VAGs were on fixed... if you get a decent head then there is no reason not to use it complete tbh...

    If coolant is getting in then I suspect its cracked between the exhausts... like I said, AMK's seemed to suffer for cracked heads...
