What are the differences between these two engines and is it possible to uprate the 140 engine to be a 170?

I've noted that the injectors and turbo on the 170 are more powerful, there is also a remap difference.

Surely remapping a 140 to 170 avoids the lag issues you get with a larger turbo and should be a better car than a base 170 although the tuning options on a 170 are much better and you could remap this to around 200bhp easily.
