Easy money
If you are low on cash, just defeat one of the opponents on the black-list. You will get two marks to use on several different things. Do not use them on the Uniques early in the game. Instead, use them on the middle or the left 'Random' choices. They should always come out to either be a big cash bonus or the opponent's pink slip.
Because you can repeat blacklist races you have completed and still earn money for it, do any of Kaze's tollbooth races. You will get 10,000 for winning. By this point in the game you should have hopefully obtained the Porsche Cayenne from Baron. If not, your fastest car should do fine.
Easy upgrades
Before you can do anything, you must win the Burger King Challenge. When you win it, you will unlock all unique parts also called Junkman parts. Get any car and put all the parts except performance. Once you have your car the way you desire, go to the performance shop. Max out your car by pressing X. Then, put the Junkman parts on. Max out your car again. Then put on the Junkman parts again. Your car should be fully upgraded.
Nitrous and Grip
Hitting nitrous torques the chassis back, giving the rear tires immensely more weight under the new acceleration. The end effect is that you will go straight. If you find your tail sliding out or are about to spin out of control, hit your nitrous. You will be surprised at how fast you will get straight again. This is a great trick in combination with Speedbreaker. With the correct timing, there is no corner you cannot take at any speed.
One stop shop marker
Press Up2, Down2, Left, Right, Up, Down at the 'Press Start' screen. A special marker for the Junkman Engine part will appear in the back room of the One Stop Shop in career mode. This code can only be enabled once per career.
Quick start
Pay close attention to your tachometer when launching from the start line. Grab a perfect launch to gain a few precious seconds. When the needle turns blue drop the clutch and hold on.
Recommended car
The best start car is the Cobalt SS. Use that car until you get the Eclipse. When you win blacklist races, try for the three '?' markers. You can get cash or the pink slip car. If you get their car, go to the safe house and sell it. You can get good money by doing this, and get unique upgrades after you start getting into the visuals after you switch from the Cobalt.
