[s-cars] Fw: Hoppen Stage IV - boost (or lack thereof) issue

[Paul Friedenberg]

If I were you, I'd go with a Garrett ball bearing turbo. No BTDT but they
are lightyears ahead of the KKK stuff. Faster spool up, and the life of a
ball bearing turbo greatly exceeds the bushing(?) style of the KKK. As far
as size, something around a T4 would probably work. Euro car services has
T4s, but make sure you get the ball bearing type, not all Garretts are ball
bearing, its an option.

Paul '95 S6, wishing I had a Garrett instead of my RS2
