turbo worth it?
hey i found a pair of turbos on cl from a b5 s4 and hes selling them cheap. 500 for both and i was wondering if it would be worth it to buy one and make my own custom turbokit for my a4 2.8l i know everyone says sell it and get a 1.8t but i cant do that. please any input would be awesome! thanks and looking forward to browsing the forums!
That input is correct. One custom twin turbo Passat was built that I recall, and between fabrication, sourcing parts, and tuning, it had a build cost of roughly $11,000 and made around the power of a stock S4. There is so much more to that type of build than most people know, and historically it's come down to the fact that the guys capable of doing it don't have to ask about it. That's not a dis, just an observation based in history and experience and backed up by the results that lead everyone to tell you to just sell the car and buy a 1.8T.
What year is your A4? If you have a 12v V6 you might as well just forget about it. If you have a 30v ('98+) it's *possible*. Even then, I'd hardly call $500 for used S4 turbos with unknown mileage a good deal. You can get two brand new Frankenturbo K04 hybrids for a touch over a grand. To make that work on your car you'd need an almost complete donor S4, many hundreds (if not thousands) of man hours, and a well-appointed shop in which to work.

My bad, I think I was thinking of the F21 for longitudinal A4's with that price. Thanks for the correction!
