    I am starting to get used to the idea of twin turbo 6. They seem to have it pretty well figured out now.

    I still remember driving an old eagle talon tsi that felt like there was switch that turned the power on and off around 4000 rpm. It was horrible. That guy installed a turbo timer that kept his car running for 5 min when he parked. That sort of thing seems to be in the past though.

    Turbo is so mainstream these days with so much proven technology, all that lag and those problems are a thing of the past...

    yup... I can't think of any F/I turbo engine that doesn't make tons of power and torque low end these days. The ecoboost 3.5 in the 150 makes 400+ at 2500rpms for crying out loud.

    My only concern with turbos is repair costs when something under hood decides to take a crap at 105000 miles.

    Re: IF the Cadillac ATS-V gets a V8...

    Not really having followed the reliability of today's turbos, what's really involved in their maintenance? If they have cast iron housings, they tend to get an exterior of rust which is, of course, accelerated by the heat they see. They also have an oil supply for their bearings, I believe, so those might have to be replaced at some point. There has to be BOV, but those must last a long time unless the spring lets go.

    What else can there be?

    I just mean a twin turbocharged, multi-valve, multi-overhead-cam and all its associated hardware versus a simple old pushrod, naturally aspirated engine. You know which one is going to be cheaper and easier to fix.

    I don't know of any S4 owner that doesn't blow his $2-3K Turbos at some point in his ownership if they're stock. it's a fact of B5 S4 life, and the APB is wedged in there, so you have to remove the entire powertrain to swap them. That said, even 1.8T turbo failures are not heard of. If properly maintained on good oil, and stock boost they'll last 200K, and some of it is the poor design on the BW K03's, however, you absoultely can't let anything go, or neglect the engine like some POS 2.0L Neon, because I don't know of any F/I motor with turbochargers were turbo failure isn't a concern at some point.

    The old 40V V8's though require very little. PITA timing chain replacements (also requires powertrain removal) are the biggest concerns, but it's not a $2-3K fix.

    I hate to say it, but your concerns are legitimate, there is absolutely some truth to the idea that F/I motors have the possibility to fail more often. Will it be a problem in a ATS-V? I don't think so, even the lease's are going to get on-time oil changes and warranty fixes. On some sonic or ultra-compact with a tiny 1.4T, I'd be more cautious.

    No to BOV. The Ecoboosts don't have them...

    Thank god..
    They have a valve, but it's a BPV. It doesn't vent into the atmopshere, it recirculates it into the system. Audi and VW have used this kind of setup for years. Leave the turkey noises to the Civic's, Evo's and STi's. If they're even more like Audi/VW it's a diaphragm, not a spring and piston.

    None of that's a problem if you trade your car before 100k. But what if you decide to keep it? 100k miles is 3.5 years for me. I plan to keep my Camaro for at least 5 years.

    Re: IF the Cadillac ATS-V gets a V8...

    So, the BPV just allows the excess exhaust pressure to route around the turbo and on downstream?
