Where do I run the 'feed' and 'return' lines from/to?
westrock said:Buy "adding" do you mean the turbo wasn't originally setup for it? You would need a new CHRA (center housing rotating assembly) that has water cooling channels.
um...your "my car" says no mods.......so we dont have the info to provide an answerMikeD said:Yes, I'm having a turbo rebuilt, and in doing so I'm having them add water jackets so it will be both oil and water cooled.

so....the stock td04 and S3 td05 are both oil + water cooled already, both using stock lines...
...many other aftermarket turbos already are also...
...if your specific turbo (which is ???) doesnt come that way, then its unlikely you can, as the CHRA will not have water passages cast into it, and its not like you can carve some out
all turbos are at minimnum oil cooled / lubed......many have water cooling, mostly for warranty / longevity reasons, by manufacturer
its pretty common that we've run turbos (in swaps) with water ports closed off, and just oil lines......with no ill effect
