Greetings and I hope I am posting this in the correct subsection.

I own a 2012 Mk3 Focus 1.6 TDCi, 95HP start-stop. I'm coming from my father's 2013 Mk3 Focus 2.0 TDCi, 163HP and you can imagine I feel quite a lack of power. I bought this car for city driving and I did not agree with the 95HP power figure but alas it had quite a bunch of options on it for a pretty nice price so I just had to have it. It's a great car.

As I said, I do feel a lack of power though. I was wondering what difference is there between the 95HP and the 115HP engines when it comes to the engine components themselves?
What I've found out is that the turbo is bigger on the 115HP version, but is that all? I'm asking because I want to upgrade my car to 115HP (no remap - basically stock 115HP engine) and then remap it to reach around 140HP. Is this doable or am I crazy?

What do I need to know about this? Are the injectors the same on the 95HP? Will I need a better clutch to deal with the extra torque (assuming this is easily possible? What else is there to know? I'm quite confused because I haven't found any decent info aside from the turbo models. Haven't even found good info on the Mk2 engines for that matter.

Of course if what I'm saying is mental by all means I will content myself with just a remap, bringing the power figures to around 120HP. But I wanted to ask you kind people.

Thanks in advance!
