Would a 9.6V 1400mAh Battery be Good Enough for My Upgrade

The Sorbothane cushion is suppose to do the same thing as the Systema silent piston head and cylinder set at a much lower cost and complexity.

The hotter the spring you use, the more stuff you'll have to swap and the greater the chance of something failing. Not to mention it'll decrease your ROF. One basic rule to upgrading that you haven't seem to learn is that, all else being equal, you increase fps first by increasing air seal efficiency, not but simply tossing in a hotter spring. You might be better off finding someone to do this for you.

You'll also need to change your bushings to metal ones, if you still have the stock bushings. And replace the hopup bucking, too.

Finally, version 3 is plenty tough if you upgrade correctly.

Remember that a tightbore barrel can add up to 25 fps to your velocity, so take that into your spring calculations to try to stay under 400.

My CA M15 rifle has a Prometheus MS110SP spring that got the rifle to 365 on its own. Adding a 6.03mm tightbore shot that up to 390 fps, and to me, that's an ideal velocity - just under 400. My custom C8 has the same spring. It shot 360, and adding a tightbore brought me up to 380. My JG 416 with its stock spring shot 390. I installed a tightbore and that brought it up to 415, making it too hot for the fields I've played. Installing a better hopup rubber even increased that up to 430.

So if I were you, I would consider you try to look for a spring that will get you about 370-ish fps rather than getting a 400 fps spring.

it would probably last forever with good shimming.

the systema silent piston head + cylinder head absorbs most of the shock, which prolongs your gearbox life by a VERY long time(V3 never breaks to begin with).

Don't bother using sorbothane pads for now, I don't want you having piston alignment problems and end up having to buy new parts all over again, just go with what I suggested.

oh, and Systema metal bushings if you don't have metal bushings installed already.

I've used the sorbothane pad, I found the piston displacement was not significant.

The most detailed review I've seen of the Systema silent set doesn't seem all that impressive. Maybe the tester didn't install his correctly, but then who's to say a newbie to upgrading would?

It's his first time opening a gearbox. I know you've had good experiences with sorborathane, I have too, as well, but being a first timer the chance of screwing something up is generally high, so lowering any risk of shreadding the piston is good.

I personally have a systema silent in my gun, and it indeed DID make the gun noticeably quieter. But he isn't looking for quietness, he's looking for prolonged gearbox life.

I dunno if going with a silent piston head in this case would decrease the difficulty involved; if he keeps his TM piston, he'll have to go through getting the whole thing apart to replace the piston head and spring.

No matter which one he goes with, I still think he should seek assistance, even if it's not in the form of a gun doc, at least a friend who's done this before.

Also, is there some sort of budget involve? We can go least-parts-possible, but I personally don't recommend that. If you're going inside the mechbox anyways, might as well replace everything you want to now.

And is the gun even meant to stay inside the average Ontario field limit of 400fps? The OP seems rather keen on 400+.

I told him to use Prom M110 to keep it arond 390FPS.

but I do agree with the seeking help....

Well, I've already opened up my gearbox twice. The first time I did it was when I installed 6mm Deep Fire metal bushings and the second time was when I installed a Prometheus MS90SP spring, Prometheus Poly Carbonate piston and a Systema Duracon piston head.

Now, I'm still a newb by far when it comes to upgrading but I'm pretty confident on working on the gearbox on my own. After installing these previous upgrades, my gun had never had any issues firing. But that's why I'm on here, to ask questions and learn as much as I can. If anything, and I do end up achieving over 400-450 FPS then I won't even play with my SIG 552 on the field. Instead I'll just play with my stock TM G36C, which I don't plan on doing any upgrades to until it breaks. But I am looking for the best way to keep my TM SIG 552 gearbox life and stability for as long as possible with the upgrades I want to do, and the necessary battery type to run it.

BTW, what are sorbothane pads? I've never seen or heard of them before.

Why dont you just buy a drop in mechbox? Thats what I did and it has been amazing...

That's something you should've mentioned off the bat, instead of letting us assume we're dealing with a stock mechbox and zero upgrade experience...

With the parts you have already, you could get to the high-300 range simply by replacing your spring (Promy MS110 or Modify S100+) and maybe your spring guide. Durability and battery life (assuming 9.6v 1400mah mini) should not be an issue. I run my S100+ all day on that battery.

That's some really cool looking stuff, less impact vibration on the gearbox equals to longer life span. I'm might have to get me 1 or 2 of those. Thanks for the link!

So here's my new revised upgrade parts list:

A.R.S. Sorbothane Cylinder Head Pad
Prometheus 6.03 EG Inner Barrel (455mm) covered up with a TM Knight's Pro Silencer
Prometheus EG Spring Guide with Bearing
Prometheus Hard Piston
Prometheus Non-Liner Spring (MS110)
Systema Air Seal Nozzle
Systema Anti-Reversal Latch
Systema Helical Gear Set 1 (High Speed)
Systema High Speed Metal Bushing with Bearing
Systema N-B Cylinder Type 1
Systema Silent Head Set
Systema Turbo Motor (Medium Type)

Now, what kind of battery should I get? An Intellect 9.6V 1400mAh Mini Battery or a FireFox 11.1V 1600mAh Li-Po Mini Battery?

i dont think your systema anti reversal latch, gears etc are necessary. Run stock gears, Prometheus airnozzel is great. if its cheaper, get that, if not, stick with the systema. dont replace the motor. Honestly, to simplify this, just get a Guarder cylinder set and pick up a sorbo pad. you will be fine then. if you want a little bit better quality, than get the following. i just picked up the following for my TM M14. I have done a lot of research, be it searching on the net/ASC, or talking with gundocs. with the following parts, i have concluded that you honestly cant do any wrong, so long as you get a gundoc to install them. hope this helps

Prometheus or Guarder Spring (100-110)
Prometheus Air nozzle (i have heard good things of this, especially in the TM M14)
Prometheus Hard Piston
ARS Cylinder Head
ARS Sorbo pad
Prometheus Spring guide

NOTE: for ARS products, contact Tirador. you can find his thread in my link in my sig.

That will give you power and not put too much stress on your internals. Other than that, you dont need anything else. Your gun will shoot hard, and last long and best of all, it shouldn't cost you that much.

I wouldnt go with the turbo motor i would go with the magnum motor it will give you more torque to push your spring and still give you a great rof. Also Sig's use short motors not medium motors
