I'm starting to shop around some to amass parts for a turbo build. There's an Audi S4 twin scroll turbo FS near me, described as having minimal shaft play. I'm not really sure where to start to find out exactly what size this turbo is, or if it'd be a good fit for my build. Anyone know anything about this turbo? I do know that twin scroll is a very happy good thing, but obviously if the turbo itself is too big, it's not going to do much for me on a stock internals 7A.

Actually, I read that article in last month's issue, or is it this month? IDK, one came the other day and another came yesterday So yes, I'm all about the twin scroll design, it looks like a great setup and option for the 7A. I just want to make sure the S4 turbo (found out it's a Borg-Warner K03 or K04, probably 03 because it'd be too lucky for it to be a k04) isn't *too* small. It looks like it went on the VW 1.8Ts too, so it seems to be fairly well suited for a 1.8 as well as the S4 motor, which I believe is like a 2.3 or something to that affect. Just wanting to know who, if anyone, knows anything about this specific turbine, and what info they have to offer on it.

We'll talk in 3 weeks when I see you, I'm not making any big moves yet anyway. Bottom line is there's always that damn $$$ factor hanging over me, so in the meantime I'm just trying to research, learn & explore my options.

Need anything from Oregon, by the way? I'm comin', for real this time, come hell or high water (or both!)

Found out it's a T2 out of an '87 Audi S4. Anyone?
