we need spechs for the fisher price motors and through the normal gearbox
Searching always helps… 
here is only one example… you will probably even find more if you search for it… good luck.
and another one…
thread which was started by Paul… (one of the best mentors) who has discussed specs for each motor.
Perhaps you can share the fruits of your research with us by editing this page on FIRSTwiki: http://www.firstwiki.org/Fisher_Price_motor
Im not sure if the 2004 are the same as 2003 but here it is straight from first

probably the best source for information on the FP motor from Johnsen electric is here , the acutal product fact sheet. I can’t say for sure just how upto date that information is, but it’ll be close.

Remember, there are several incarnations of the F-P motor. Beware.
(And the spec sheet posted by Andy is correct for the 2004 motor.)
Please see this post here.
It is the spec sheet I gave to FIRST last year that I received for our motor in the kit. As you can see, it has much lower torque capacity than the one from the Johnson Electric web site. There are many, many different flavors of this motor so you must be very careful not to make any assumptions. The pdf in the link above is confirmed to be the exact motor we received from FIRST.
