Depends what dci you start with your potential
The 65hp has ~70hp when run in and with a tunning box gets about 84hp, remap about 88hp
The 80hp has ~85hp when run in and with a tunning box gets about 105hp, remap about 105hp
The 100hp has ~105hp when run in and with a tunning box gets about 115hp, remap about 120hp Difficult to know for sure though as thereve yet to be worked on AFAIK
The 65 and 80 share the same engine only difference is bigger injectors fuel pump and an intercooler on the 80.
There load you can do upto a point then it becomes big money.
All the usualt petrol mods will work intake + exhaust + chipping. Although as its a dci chipping will have a greater effect as the turbo pressure can be turned up easily.
Unlike a petrol air fuel mixture doesnt matter as much as fuel = power (upto a point)
What exactly are you looking for I think the old 1.9 Megan engine with 80 or 110hp can be dropped in Mk2 1 Clios easily enough but Mk2 2 have the ultiplex wiring so its more difficult.
