I think based on repair costs and the ability to work on the engine, as stated by FasterA4ThanURs.......I'd have to agree with FasterA4ThanUrs.

But I'm 2.8 V6 so what the hell do I know.

 

youre shot on this one... it is absolutely more reliable. The 2.7's are great setups that can make some big power, but have more issues than pyschitso children lol. I dont know a single person that has an S4 without some serious headaches in their past or present... They are MUCH harder to work on than the 1.8 and once the modding begins usually run into lots of problems.

On the new S4, they built two identical engines. One supercharged and one biturbo. The supercharged one was a lil less impressive, but was way more reliable and obviously won the battle.

 

yeaaa kayakman id have to agree too.. anytime youre talking a single turbo setup vs. a biturbo setup expecially given what we all know about the 2.7t platform.. its gunna be more reliable and easier to work on.. the big thing being the easier to work on.. just conversations ive had with my shop whos owned and run by one guy granted.. whos an audi vw geek, he sometimes turns away 2.7 jobs just cause he doesnt want the headache.. but it also has to do with the fact we live in vermont and if the car is a new england car even the "easier" jobs are just a nightmare.. but even that aside its just asking for trouble.. plus the money involved its just not worth it
