Hi
What is your engine? AFN 110cv?
If you want to do it ~ 200cv, you will have to buy:
1. turbocharger from A4 B7 2,0TDI - 170cv(P&P) code engine - BRD

garret 130cv vs kkk 170cv
You still have the possibility to install turbo from A4/6 2.7 TDI or 3,0TDI(GTB17VK and GTB22VK), but it requires processing vacuum and welding manifold. Very efficient turbocharger spins after repro to 5k.
2. injectors fratelli bosio 0,230mm (hybrid)
3. Injection pump from the engine 1.9 TDI 90cv code AHH (a4/passat 99-01') The so-called eleven(11mm)
Standard on your engine's pump with piston 10mm. It's too weak to do with the 180-200cv.
4. Map sesnor from seat Leon Cupra 1,9 TDI 150cv code engine ARL (not P&P)
5. Clutch from Audi A4 B6 1,9TDI 130cv 5gang(228mm), or gearbox from A4/6 2,5TDI 6gang (240mm) code: DQS
6. FMIC
7. Repro
If you have the parts, it's no problem should attempt to achieve power in the range of 190-210cv & 400-430tq. Financially it comes out the same as the 130cv motor mount with larger turbine.
