Replacement dc drive motors club car

[jeno]

I have a dilemma I need to get a golf cart dc drive motor that will at least make my 1993 club car ds 36vdc electric go to 18-20 mph. right now it goes a slow 13-14. I called d & d and they recommend the "two two" motor which is sku 170-002-0002. but I have worked on other 1993 golf carts same year and voltage 36 vdc by the way and I see a bigger motor and all these golf carts have the same as mine does i.e. resistors, and the slide switch non electronic controller. now the other carts have a ge model 5bc49jb3071 which I cross referenced for the higher d & d 36vdc sku 170-003-0002 which specs out higher rpm than the motor d & d stated for my cart. both of these golf carts are the same year and set up the same but get this the 1993 club car with the ge motor runs at 18-19 mph. so d & d warned me if I put the sku 170-003-0002 in my 1993 golf cart at 36vdc it will blow resistors. I cannot figure this out. can anyone elaborate on this? I would like to put the sku 170-003-0002 motor in but i'm afraid it will blow resistors when on the same golf cart it does not. thank you for any help and experiences
