My M249 shoots 1500rpm at 380 fps and my SW-COMP, which is much more sensitive than a simple mosfet switch, never overheats.

Prom 6.03 barrel at 509mm, that's about the max recommended length for regular cylinder
G&P M140 or M160 motor (M160 is one of the least expensive high power motors that's good quality)
firefly hop rubber
ARS piston head, provides ridiculously amazing seal
ARS cylinder head, provides great seal against air nozzle, which is extremely important for maintaining accuracy.

A simple mosfet is a great idea to maximize the power you get from NiMH batteries
A SW-COMP however is completely up to you, I personally think it's not needed in a semi only platform.

a 9.6v mini coupled with upgraded wiring, G&P M140 or M160 and a MOSFET is more than enough juice to give you a nice snappy trigger response.

And unless you do the insulation mod to the systema magnum motors, they're absolute fucking garbage. Honestly the worst stock motor you can buy, but it's really good once you insulate the end bell.

Wouldn't trust any guarder gears either, I've seen no less than 3 brand new sets get stripped in their first game. KA gears are fine, KA pistons are okay.
If you scrap your piston, get either a marui, system super core, or prometheus piston.
I run nothing but prom gears and pistons, they take a shitload of abuse, and they last a long long time. I'll usually get 2-3 seasons out of one before i decide to change it, and it's still not stripped.

Remember the most important thing in your setup is going to be achieving perfect compression. You want all the parts to mate together as well as possible. Any leak, especially between the hop rubber and air nozzle, will cause loses in accuracy.
