1.0l ecoboost : 100 vs 125

[wealdman]

Any opinions welcome on which engine is the "sweeter" - by which I mean that elusive combination of quietness, smoothness and flexibility. Or perhaps there's no difference? Never mind the top speed, the ultimate in acceleration or even the expense!

I believe the engines are the same so go for the cheapest option and get a remap if need be.

I have had both. The 125 was the best in 2/3 gear. I had 100 remap using bluefin to 139 but was a bit worried on reading that the gears boxes were different so I removed bluefin and have it 100 and its good. Lot quicker than my 1.6 focus.
