getting the car and all its upgrades as quickly as possible in Fallout 2 (no grav-plates)

upgrades:
Fuel Cell Regulator: 05:33
Fuel Cell Controller: 16:44
T-Ray's Adjustments: 27:49
Ratch's Blower: 28:45
The grav-plates require you to beat the game first then get your car stolen for the first time in New Reno, so therefore they're not included
