I fitted in mine this:
-ZF SACHS Performance reinforced clutch kit from Sachs's online shop
-New OEM dual mass flywheel
-PD140 oil cooler
-Turbo Garrett GTB1749V from Darkside
-Turbo braided oil feed line from Darkside
-DPF delete
-Custom remap
Now I need PD150 injectors and a new remap. The injectors aren't cheap, though...
