Was looking at getting an S4 sometime in the near future, but my only problem is the fact that the S4 is a Twin Turbo, and Turbo's are extremely expensive to fix. So my question is, has anyone had a Turbo blow out on them, and if so at what mileage.

Thanks, Derek

...at the top of the screen. AW's archives are deep and wide, full of more information than you could possibly use.

Yes, S4s have a notable rate of turbo failure. There are lots of ways to prolong their life. Many of us own these cars fully aware of this weakness, and love our cars anyway, and have found it a great excuse to throw in better turbos! But don't expect the B5 S4 to be cheap and reliable. If you want reliability, buy a Camry. If you want a great performance sedan, study the archives, post more questions, and welcome to AW!

1st its not twin turbo its BI turbo big difference, yes the stock turbos will evenutally fail if you use a chip. Hell I had them fail when my car was stock. You are going to need K04's so expect to pay about maybe 4-6K with parts and labor.

Are you kidding? Biturbo is just a marketing thing AFAIK.

no Bi turbo is two turbos working parallel twin turbo is not. come on dood =]

So what is the 996TT? It is referred to as a twin turbo all the time and the two turbos work simultaneously.

confused germans? I dono not going to argue but cars like the 300z are twin turbo .. Two turbos mated together

maybe paternal twins but not identical i.e. rx7, supra. Things like that labeled as twin turbo cars with one smaller than the other.

hey, I thought it was because left/right turbos are not identical "twins"!
