Audi A6 C4 TDI 2.5 104Kw 5cyl.

Hello I have an Audi A6 C4 TDI 2.5 104Kw 5cyl. and i want to find some performance mods that i can do to it but i cant seem to find any can some one help me plz. thank you.

This engine was not available in the US. I guess that`s why the reply rate's so low. The inline 5 can use the same nozzles as the 1.9, it's basically a 1.9 with an extra cyl. I belive it uses a WG turbo. A frind has one with just a tune(170hp) and I've been told that's the limit for the turbo.
Shadowmaker have pulled some 300hp from this engine, mayby some of the finnish guys have some more info?
