Will a ver.2/3 high speed gearset work in a ver.6?

I searched and found a couple threads where people where asking how to up the rate of fire in a P90 and where told to get high speed gears. This I already knew but when I actually looked for them I found that no one makes high speed gears except for ver.2 ver.3 and ver.7 gearboxes. Would the ones that are Ver.2/ver.3 cross compatible also work in a P90's ver.6 gearbox?

Also will a ver.2 bearing spring guide fit in a ver.6 gearbox (I'm only asking this because I saw Illusion selling some stock TM spring guides and they where listed as "ver.2/ver.6")?

all but the super high speed gear sets will work in version 6.

And yes, version 2 spring guides will fit version 6 UNLESS IT'S GUARDER.

Thanks, just what I wanted to know
