I am looking to buy a Peugeot 2008 1.6ltr Diesel and preferably the 120bhp version (with 6 speed gearbox).

I am wondering - as I can't seem to find anything on the subject - are the 100bhp and 120bhp engines the same engine but just chipped for the power differences? Obviously the extra 6th gear does not give it the extra power... but i am just curious re: engines of the same size but differing power outputs.

Most of the ones listed are at minimum 34k mileages and upwards to 120k... so thinking long-term inclusive of potential engine rebuilds later one.

Reason for asking is that I am finding it very difficult to find a good condition 120bhp 6 speeder - but can easily find the 100bhp 5 speeder in good condition (yes, I am just picky when it comes to looking for a good condition one as several i've seen have issues with scratches, slight dents, trim issues... and other nit-picky things) inclusive of MOT History checking (it seems the 100bhp versions have no issues/advisories).

In the motoring world some engines and gearboxes can be transplanted into other similar vehicles - so wondering as I really would like the 6 speeder for obvious fuel (mpg) reasons... but at the same time might look into the possibility that a 6 speed gearbox could be fitted to the 100mhp version... although both 100 and 120bhp versions seem similar factory mpgs.

Reasons to my questions?

I currently have a company car but in 2 years time they are forcing EV and Plug-in Hybrids... but with my travel UK-wide (and I can't have an EV as no possible way to fit charger where i live... and also do not want to be spending my life charging every day on the road) I would like a diesel that would benefit from great mpg... and I kinda like the previous 2008 version to the new one as the new one is 1.5ltr and only 110bhp... and lesser mpg.

Thoughts welcome on this ambitious question.
