the X motor getting hot is common.
Putting a heatsink, fan or both on it is also very common.

This fan mount works very well: http://www.thingiverse.com/thing:128526
takes a common 40mm fan and simply fiction fits on the bottom of the motor

If the one you have is working I'd put a sink or fan or both before I'd go to a nema 17. The added mass will give you issues with your Y axis.

I'm gonna have to change the carriage as I brocke one.

so while doing this, I was wondering if it was a good move to replace the original stepper, they heat a lot,

and I read somewhere on this forum that they where push over the limit.

(like more voltage that they should)(on stock sd3)

now what sort of stepper would be an upgrade?

I don't even now the exact model the sd3 use. (they look like nema 14)

I have another 3d printer a microdelta and it use nema17 they are bigger for sure.
and they never heat even when I print for 18+ hours.

The solidoodle cannot print 8h+ without some sort of heat dissipation

I know by the look of it the only thing that will still be stock will be the frame....

but it's a very good one...
