Generally those models have pretty decent FPS, so leave the gearbox alone.
Get:
Madbull 6.01 barrel, its the 500mm size or something like that
Madbull Ultimate Hop up OR Modify awesomesauce hopup
G&G Blue Hop up rubber
Optional: an 11.1v battery to decrease trigger response time.
Run good ammo through that setup and you should be pleased with the results.
