I would like some more power from my C3, which is a 8b 1.4 HDI from 2004 with 178.000 on the clock
What do you guys ( or girls) have for tips or alike for performance upgrades?
Heard a guy talk about using the turbo from a 2.0 Peaugeot HDI ?
As always there is a chip-tune / optimization which I want to get, but want to do any upgrades first
So... Hit me

I think you will find that any engine modifications like turbo will just be fighting against the engine performance map in the ECU, so I would suggest you go for an engine remap.
But, you wouldn't want to push a worn engine to give more power. If the car has faults then you may not be getting the power you would expect before the mod and definitely not get the most from the remap.
Is the servicing up to date? (cam belts do break etc)
Is its really worth spending any money on? When you could buy something with more power from its original design?
