In career mode, purchase the Volkswagen Jetta GLX VR6 from the Volkswagen dealership. Next, head into the Garage and the Buy Upgrades screen. Enter the "Engine and Power" section and purchase every engine upgrade available except for the Engine Swap (that includes each individual turbo upgrade, each intercooler, etc.). When you've finally purchased every upgrade, you can then purchase the second engine that's available in the Engine Swap for 2,500 Cr.

After purchasing the new engine, re-install the stock engine. You can then sell the second engine that you purchased for 44,092 Cr (remember, you only paid 2,500 Cr for it) for a profit. You can then buy the engine again (for 2,500 Cr), install the stock engine again, and sell the new engine again for 44,092 Cr. You can repeat this trick to build up as much money as you want.

To save money on window tinting, scroll over to the color you want and press B. The color will still be on the window, and you will still have 500 credits.

Buy the VW Jetta VR6. Buy every engine upgrade and the other engine. Equip your stock engine, then sell the other engine that was just bought. You will spend 1,500 credits, but gain 45,000 credits. Then, buy the other engine, equip your stock engine, and sell the other engine that was just bought to repeat this as many times as desired. Buy a Volkswagen Jetta, then install all motor upgrades. After you install the engine, reinstall the original motor. Then, go to the second motor that you purchased for 2500 credits. Press X and sell the second motor for ten times the original price. Keep repeating this as many times as desired.

Note: This can only be done online. Have the host start the race with only a single lap. As soon as the race starts, have the host go across the start/finish line and then quit the race and return to the lobby. As the race is still going on, have the host go to game setup screen, then go to "Laps" and set it to as high as possible. The other racers in the race will finish the single lap race. If done correctly, the racers that finish that single lap race will get paid for the laps that the host changed it to when they exit.

Have two or more Xbox systems linked with their own game disc. Start each of the the games and enter the options menu. Highlight the "Credits" option, then click the Left Analog-stick. A new "Network Cockpit Settings" option should appear. If it does not, press the Left Analog-stick Down while clicking it. Set the "Host" option on one of the Xbox systems. On the other Xbox systems, select the desired view. When ready, start a game on the host Xbox. The other Xbox systems will also load the same track and show the race from the selected view.

A bug in Forza prevents players from being awarded with the prize car if they do not place 1st in the LAST RACE in the championship.To be sure to always get the prize car, keep retrying the last race until you get 1st. If you do this and have the most championship points, the car will be awarded.

Say you just bought a car off of some person on Xbox Live and you don't have it unlocked. To copy a car, you must have at least 2 profiles. Let's say the profile with the car you wish to copy is named profile A. Your secondary is named Profile B. Load up Profile B, go to Garage and select Profile to Profile. Then click on the name of the profile that owns the car you wish to copy. Find the car, and buy it from the profile, it will stay in the profile you bought it from and you will also have it in your secondary profile. Now that you have done that, you can load up Profile A and buy that car. Now you will have 2 of that car, and you can continue buying it.
