[Biturbos4] Turbos Reliability & Replacement Cost (was: 2000 S4 Running Hot)

[j y]

DEFINITELY MORE BULLET-PROOF. Plus, the sginificantly higher HP doesn't hurt either. 
 
Beaware, you just don't dump/install K04s on a stock S4. You will need to upgrade fueling, intake & exhaust (DPs) plumbing, possibly the tranny - if Tip, ECU - if you choose - u can run K04s on K03 software (stage 3- on the mod list). 
 
If you don't do these things  - you will significantly compromise the performance of the K04s - basically throwing $$$ away. Since I've already done many of these things - while still on (upgraded) K03s - it will be a relatively easy install for me (with the exception of upgrading the Tip tranny to handle FULL K04 powah).

Obviously chipping kills them a lot sooner, and people they have chipped their 2.7t should realize that, but even non-chipped car are not safe from it either. Someone on this list 2 weeks ago (sorry I forgot who) had his turbos bit the dust at the tender age of 52k miles, and he supposedly followed all the usual procedures like proper warmup, cooldown and uses synthetic oil, and his car wasn't chipped.

Do the RS4's K04 turbos suffer a similar fate with similar regularity
or are they more bulletproof?

Maybe I could persuade the wife on account of it being more reliable..
