For a 2KG AUW, none of the above will be that efficient.
If you can Limit the AUW to 1.5 - 1.8(max.) You can go with 2212 motors and in a very low budget :)

Edit : Turnigy Multistar motors are very efficient- they give more flight time - If you have the budget go for it :)

If you do go for these motors I would suggest you buy these to replace the stock prop nuts: http://www.ebay.in/itm/M5-Hex-locknuts-High-Quality-5-Pieces-/191023074309?pt=IN_Toys_Games_School_Stuff&hash=item2c79dccc05 (http://www.ebay.in/itm/M5-Hex-locknuts-High-Quality-5-Pieces-/191023074309?pt=IN_Toys_Games_School_Stuff&hash=item2c79dccc05) I had problems with the nuts loosening or falling off mid flight   :banghead: but these solved the problem. One advantage of using the Multistar 2212 motors is that they come with CW and CCW threaded shafts that will prevent this loosening.

@chintal, SS X2212 i no doubt good (i must say excellent motor) but 11" props adds a bit of heat to it. And its not suggested to use 11" with this motor for every flight cos it decreases the life of the motor.

IMO:
For 2212 980KV
with 11.1V 1045 is best suitable
and with 14.8 8045/9045 is best
saying that i dont disagree with what Chintal said but continuously using 11" would degrade the life.

If you want to use 11inch props then 2216 SunnySky should be your choice..
