Q1. the engine on the 523i and 525i really the same right / they have the same capcity, fuel consumptlon are almost the same. does that mean the engine on the 523i is simply a restricted version of the 525i engine
Q2. the 523i is 130kw/177bhp and 525i is 160kw/218bhp, assuming both engine are the same, what will be the most cost effective way to unleash the power on the 523i ? or just buy a 525i instead, I live in Hong Kong, the price difference is approx US$7700
Q3. Does the 523i has the same upgrade potential as the 525i ? in terms of power output ?

Welcome to the forum silu uu.
You can try ECU remap plus CAI. However, these may only improve your car's performance slightly but is not an alternative to the 525.

A "ECU remap" won't get you as much power as there is in the 525, as the engine/air intake probably is a bit different and so on. The parts, e.g. valves are probably also of lesser strength than in the 525 aswell.

welcome sliu_uu 
update your location under 'my controls' so we can best assist you in the future...dont know your economics, but the real bang would be the 530 if you can swing it

I do a low annual mileage and for the type of driving I do I didn't think it was worth the extra dosh. It will have a better re-sale value here as well. A 525i owner over a 523i will be lucky to get $2000 of that $5000 back at trade-in time.
I traded from an 11 month old 520i and it was the engine that made up my mind. I don't think you will be disappointed either.

Welcome aboard, sliu_uu. You won't be disappointed with the 523i.
ps. Come to the HK sub-forum if you have time.
Welcome the the forum sliu_uu.
You'll ride nicely with the 523i. It is a great car.
The larger differance will be with the 530i and then with the 550i.
No offence to the HK sub-forum, but why should you guys isolate from the rest of us?
