the reason for going to 3s is , i know how 2s was on my xt in the old brushed system and i was not satisfied with the power it delivered so thinking of 3s

There it is. Ofcourse your going to see a HUGE difference with the BL system, even on a 2s. I felt the diff b/w brushed and brushless on NiMH itself.
3s is overkill. Your going to end up straining the drivetrain a lot. Stuff starts breaking a LOT.

How about this motor / http://www.hobbyking.com/hobbyking/store/__17713__XK3650_B_3900KV_Brushless_Inrunner.html
with this esc /
http://www.hobbyking.com/hobbyking/store/__8993__Hobby_King_Brushless_Car_ESC_100A_w_Reverse_Upgrade_version_.html

and a 2s lipo,
will it be better faster and more powerfull than this setup/

The 100A ESC is good. A programming card may not be required if you want to change the setup once or twice (i feel its not necessary for bashing but would be good to have if you are interested in racing).

I feel the combo is better.

then How about this motor / http://www.hobbyking.com/hobbyking/store/__17712__XK3650_B_5400KV_Brushless_Inrunner.html
with this esc /

both 3650 motors
and the the motor is for my 10th scale 4wd truggy that is sparrowhawk xt

how about this motor http://www.hobbyking.com/hobbyking/store/__6672__KD36_60_06L_4000kv_Brushless_Inrunner.html
with the HK 100 amp esc  http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8993
and a 2s lipo,
and i guess this pinion is a 5mm 48 pitch 1 http://www.hobbyking.com/hobbyking/store/__21104__Pinion_Gear_19T_w_Set_Screw_1_10_Brushless_2WD_Desert_Racing_Buggy.html

Not too sure on the pinion... The motor might be too big for the XXT. The ESC looks iffy as well....

not a problem if the motor is big coz ill have sme extra torque,
and will it be  a ggod upgrade if the pinion is a 5mm 48pitch one, coz 4000kv will run fast plus the 3660 size will give good amount of orque so ill have the best of both worlds, ?

Uhhh will your drivetrain take more power? There are times when less is more...

the spur gear is delicate so ill have to put a metal spur. nd yes rest all diffs and all are metal so no prob i guess + it will cost me 3500 rs so i simply dont hav to spend 5500 on the 100amp hk combo.
and wat do u mean by "There are times when less is more..."

I meant more power is good to an extent and comparatively less power is good when compared to more power...
