    Didn't they use the K04 in the 8L S3 after 2000-2001 (when the revision kicked in)...

    Yes, they used K04 on the 8L S3 too.
    But on the 8P S3 it's a twin scroll K04 and I don't know if it's exactly the same as the K04 on the 8L.

    Think that was only used on the later 1.8T models mate the 150bhp or 180bhp models.

    All the press releases and reviews state it is a completely different turbo on the new S3 compared to the old.

    This is off a review:

    "The new turbocharger has a larger turbine and compression rotor than the basic unit. Its cast steel casing – produced as a single piece including the manifold – withstands exhaust gas temperatures of up to 1,050 degrees. The turbocharger generates a boost pressure of 1.2 bar instead of 0.9 bar on the starting version".


    So its even very different over a 2.0TFSI

    I'm 100% sure that the 8L S3 has K04 turbo. Try to ask this question on the 8L forum section ( i know because i did :) )

    Although i'm not sure if they are exactly the same because the K04 on the 8P is a twin scroll turbo.

    P.S. The 200 HP 2.0 TFSI has a K03 turbo that generates 0.9 bar of boost pressure.

    basicallythe k03 was used in 150bhp A3/A4, 163bhp 190bhp, TT180bhp, the K04 was used in the old S3, cupa R , and TT225, the KO4 on the new S3 is the same as the old S3 but better and internals basically to move more air and quicker.

    The 8L does have a KO4 turbo, as I had 2 of them!

    I understood from my post above the 2.0TFSI also has a KO4 turbo but the S3 turbo is a revised version of this?

    Im pretty sure that the 2.0TFSI has a new version of the K03, not sure which one though. The S3 is running a new version of the K04. I had a old pdf somewhere for the 2.0TFSI engine which showed the turbo(can't find it now though).
