If you are having second thoughts on this project/car, then don't do it. I have seen 50% of all E.V. projects fail because people get frustrated because of car issues or lack of funds to complete the project. If you are patient, you will find the right car.
As for the motor- That is a pretty big motor but I am concerned about the low current draw.
I noticed that you are from Phoenix. I use to race H.E.V.'s and E.V.'s down at Firebird Raceway during the APS Electrics from 1996-1999. Many high schools in Arizona had an electric vehicle race team with a limit of 96 volts in their class. Maybe you should call up some of those schools to see if you can get parts. I once contacted a team and they gave me their $2000 controller for free.
