Will this motor suffice?

[Napalm]

I'm building a 3DOF racing platform, and was searching for the right motors (i seem to have a real hard time finding motors, with enough power for a reasonable price)
I did find a 1.8Nm 3A Bipolair stepper motor of this size: 57x57x76mm
Attached is a Worm drive gear 20:1 with size: 97x80x63mm
With the motor and worm drive having a total length of 170.5mm
But it doesn't note the output torque from the stepper nor the gearbox, So i'm hoping some have enough experience to determine if this motor will output enough power
