What's the bad things about getting ITK-30?. Do i need new reinforced gearbox for my TM SIG 552?. or anything else?
And if i m getting FTK-30, do i need anything else?.

Thanks in advance.
Please reply!!

what bad about the ITK-30k, the spring will be pushing out about 500fps, which isnt allowed for aegs for games here, the infinate gears will dramatically decrease rate of fire, for a spring that big u will probly need a re-enforced gear box

if i were u, i would go with the second kit, but put in one of those silent head piston kits, with that spring and the silent head, u will be pushing out 400fps or just over that, also with that silent u will relief some stress from the gearbox, also u have a version 3 gearbox, which arent known to breaking that easily, so with that sp120 i think u would get by without re-enforcing the gearbox

thx dude. very nice advise!. Well, right now i m not in canada, but in europe. haha. So if i want to get 150 kits, i ll need new re-enforced gearbox, and on top of that,i ll need the new motor too right?.
But are u also recomendding me getting new motor for 120 kits?. Just for safety, i mean. But if TM's motor can hold m120 for long time, then i ll stick to TM's then.
And i m upgrading my SIG now with new tight barrel 6.03 mm. So i m looking forward to see that combines with the kit soon.

and...do u have any ideas what parts should i get for my JG HK416?. Out of the box performance already 435 fps, but i dun think this will last that long, since i heard that i need to do proper shimming on gears and more modifications to internals, to make it last long. Recently i just installed new tightbore 6.03 mm in this gun. Accuracy wise..damn Nice!!.

lol, if u r in europe, u wont be able to import ur airsoft gun into canada. just to warn you

but what i recommend is stick with the m120 kits, and maybe a torque motor, remember that u have small battery so u dont have the amps to turn over a regular motor with that spring in it, so u will need a torque motor instead of a speed one (if that makes sense)

its also late at night(more like morning), so there might be something im over looking too

hmm maybe upgrade gears, piston, and get a silent piston head to take ease off the gear box, that probly the bare minimum

thx again...

thx again dude
