APS ASR 112 - Modifications?

[Luke.Davies12]

Wanting to get back into Airsoft soon but wanting to upgrade my APS ASR 112, looking into getting a better motor, inner barrel, lipo battery, mosfet etc but no idea what will work well together, what volt battery to get etc. Any help would be appreciated on trying to make my rifles performance nice and reliable.

It depends on your intended performance figures, what would you be looking to achieve in terms of;
* FPS
* Rate of fire
* Trigger Response
* Range

And what is the budget?

FPS id like to keep at 340-350, Fast rate of fire, quite a sensitive trigger response, Short to mid range engagements, as for budget im looking to upgrade over abit of time before i get back into it but dont want to go ultra expensive.
