    ...but yes you're absolutely right -- I wouldn't be modding/tinkering with this one, it would be strictly my wife's car. I'm just shocked that modded A4 2.0T Quattro cars are so slow, I thought that once dedicated owners got them, they'd make them fly. I mean c'mon, we're talking about 10-year-old cars here!
    Well, if you're sticking with a K03 and internals, there's only so far you can take a 2.0T. Built or not, there's a limit on how much a K03 can flow. IIRC, my mechanic, an Audi/VW specialist said that with 1.8Ts, having a good tune once you go past 300 wheel horsepower becomes very important to avoid breaking the stock rods. I wouldn't be surprised if the 2.0Ts are similar.

    Most of that applies to Mazdaspeed3s as well, though they start with the advantage of an extra 0.3L of displacement and a twin scroll K04, which (along with less weight) is why they'll definitely get into the 12s with similar mods, and high 11s on a good day with slicks. Not wanting to do internals is why I'm leaning towards a built K04 instead of something bigger. Even a stock-sized turbo can push the stock rods to their breaking point.

    With modern engine management and design, turbo engines don't need to be as overbuilt as they were in the 1990s, which is good for OEMs worried about drivetrain cost/mass/fuel economy/etc. Still, I think a lot of the overbuilt reputation of 1990s Japanese turbo engines was overstated. They make aftermarket internals for all these engines for a reason.

    Yeah but the turbo size isn't really the defining feature here, it's the lack of built/sleeved/bored 2.0 TFSI's in A4's. The factory rods in the stock mill can only handle 350 crank HP max -- and some Audi forum folks were saying they knew of failures under less power than that.

    Ultimately I did find some built examples of this mill, btw: in VW GTI's. There are a few 550-650 crank HP 2.0L TFSI's out there, which is cool (and strangely reassuring!).

    @JeremyClarkson So last night I presented a big award to the all round good geezer, Roger Daltrey, who is 72. inches tall.

    We've changed forum locations too many times for me to dig it up, but I remember making a comment several years ago to the effect that I thought that, as stability control got more sophisticated, some high performance cars might start being designed to be inherently unstable. They'd effectively only be drivable with their stability systems activated - without them, they'd be extremely difficult to control.

    Seems like that prediction, at least, has come to pass.

    My boss has two cars - a '13 F150 and a '16 Land Rover. Today, she got notified there were new maps available for both cars, which to be suggests they are coming from the same place. It makes sense, there are only a couple companies that own all the maps. BUT, the Ford costs $149, the Land Rover $199. LAME.
