    Hi guys I've just been to look at a MK4 gti golf (AUM). the car is in mint condition and has 89k miles, the problem is that I noticed it was an AUM engine but it has an AGU cyl head.
    when I asked the owner he told me that the car broke the timming belt and he had a s/h head fitted has it was cheaper than to have his 1 repaired.
    Can this be done??
    will this cause any problems??
    any comments will be a big help

    Thanks
    Aaron

    No probs really, as everything bolts onto it from the AUM.

    AGU is also a large port head, and as it was a AUM to start off with, it should have the k03s turbo :thumbup:

    Quite a good setup really :thumbup:

    As above it will be okay providing the ancillaries from the old head were swapped over.

    Inlet manifold would have to match, but throttle is different... So all depends if it was done right

    As above, if you transfer the base engine AUM, intake VVT adjuster, chain, cam cover, then reuse an AGU intake manifold, you can bolt on the E-GAS throttle and plug in the ME 7.5 system to get the car to work.

    thanks for the help guys, the car seems to drive ok, I take it that if the tentioners had not been swaped over the car would run like a bag of spanners??

    Nah, but you would have the engine management light illuminated.

    Hi Guys ,

    So , if I read correct

    AUM VVT fits like a glove into AGU head
    VVT chain must replace non VVT chain

    Is that correct ?

    Thanks

    Yeah, the vvt tensioner will bolt in. According to ETKA the cam chains for the AGU(non vvt) and AUM(vvt) are the same so wouldn't matter.
