Default Repost. ? regarding 1.8t

Since 1997
(some improvements I know of)
1: Turbo heat shielding and oil line shielding
2: Variable valve timing ( intake, exhaust or both???)
3: Drive by wire

feel free to add to the list.

As a side note; Is the B6 exhaust system more or less restrictive being a semi dual exhaust?

Default you have the K03 Sport

most of the 1.8Ts had the basic k03, in 01 they altered part of the internals of the turbo. Do a search you'll find lots o' data

Default They made the first change to the K03 in 2000.

Not sure if it changed in the first half or the 2nd half of the 2000 production line. Then 3K made another change to the K03 and K04 line in 2001. Most of the changes were in the thickness of the shaft and the angle of the blades.
