Entering a race with a higher horsepower:
If your car has a HP over the race's limit, take it to the test track under max speed and go to settings. You can remove certain pieces of your car from here to lower the HP.

Fast cars:
The fastest car in the game with best the handling and acceleration is the Mitsubishi 3000GT with all tuning for 930 hp.

The fastest car is the GTO*R. Tune it up it will easily beat all the other cars.

The fastest car is the Supra RZ. Be careful though, because it is a FR car and easily spins out.

The car with the most power when fully tuned is the Nissan Skyline R33 GT-R. With every single upgrade enabled, the car will have 955 HP. If you change the gear ratios, the car will go at speeds in excess of 600 mph -- however, there is no track long enough or strait enough in the game to reach that speed.

The purple Concept Car is the fastest car in the game. When properly tuned, it will beat any car in the game, including the GTO Twin Turbo and Skylines, by a good ten seconds in a three lap race.

If you have a 4WD or RWD car with at least 700 horsepower and it has the Full Racing Transmission, you can set individual gear ratios to make it faster. First, set the final gear to level 35 on a Supra (for example). Set each gear down three sets (for example, 0.332 to 329). Go to the Max Speed Test. You will notice your car may be able to top out at anywhere from 200 to 250 mph. Remember, setting the individual gears improves acceleration. Setting the final gear improves top speed.

Recommended cars:
Some people think that the GTO Twin Turbo is the best overall car but the used R33Skyline '95 GT-R Vspec has better speed, acceleration, and slightly better handling.

Although the Skyline has more horsepower, the best overall car in the game is the used 1995 Mitsubishi GTO MR. Fully upgraded, it has 930 hp, can reach speeds in excess of 260 mph with a little tuning, and has a better 4WD system than the Skyline.

The best car in the game is the Mitsubishi GTO LM Edition. It has the best handling around turns and of course on straight aways. You can also go into turns very fast if you know what you are doing, using the brakes to help. Then you can accelerate out of a turn very fast. The top speed is also great.

The best car in the game is the Mitsubishi Galant (the most expensive version), if you tune it up to the maximum. With everything, it goes about 220 mph and has the best handling.

The best car is the GTO Twin Turbo, when it is tuned up to the max. It can reach 930 hp and travels at a maximum speed of 405 km/h. This will set you back a bit, as it costs 43,000 credits and you have to buy all four turbo kits. You can buy a used GTO '92 Twin Turbo for 16,000 to 18,000 credits. This will tune up to 928 hp and can still reach the speed of a new GTO fully tuned up.

Best bargain when selling:
When selling a car, look around the different car dealerships to see where you can sell a car for the most money in return. Note: The red Chrysler Dodge Concept Car cannot be sold to any manufacturer.

Easy money:
Buy a car (the Dodge Viper GTS recommended) and do not make any tuning adjustments to it. Then, enter the Normal Car (Commercial Cars) championship. There are five races each with five laps, and for every race you win you will receive 50,000 credits. Additionally, if you manage to come first in the championship, you will receive 100,000 credits. Altogether, that makes a total of 350,000 credits.

If you have 1,000,000 credits, buy a 180SX and enter the Turbo Car Cup in GT mode. You will win easily, giving you 300,000 credits and a R33 drag car.

Get a Toyota Road Car, which costs1,000,000 credits. Tune it up with stage four turbo and race it on the Tuned Turbo Cup on the Test Course. if you win first place, you will get 50,000 credits and a car worth 250,000 credits. The next time you win you will get a car worth18,000 credits, then a car 30,000, find finally a 250,000 credit car.

Get an A class license and then buy a Dodge Viper. Enter the normal car championship. For every race you win, you will receive 50,000 credits.

Get a very good car that can beat rally cars (around 400 or more horsepower) and race the GT World Championships. Race in the series race. There are ten races in all, and each gives you 10,000 credits if you can finish them all in first place for a total of 100,000 credits.

Save money:
When buying a car with a lot of HP, it is better to buy a cheap used version of the car. You can upgrade a used car more than a new one and it saves money.

Duplicate parts:
Purchase two identical cars. They may be given different color schemes if desired. Buy as many parts as desired for the first car. View the list of fitted parts of the first car from the garage. Switch to the second car, get inside, and view its fitted parts list, which should be empty. While remaining in the second car, enter a spot race. At the qualify options, select "Machine Setting", then "Change Parts". All the parts from the first car should be available. Exit the race and return to the garage. View the list of fitted parts for both cars to see that all desired parts have been duplicated. Note: Only items available on the "Change Parts" menu may be duplicated. This trick will not work on cars that have been awarded.

Conserve memory card slots:
Play the game in arcade mode, exit, then enter simulation mode and save the game. By doing this, the arcade and simulation mode information is saved together, cutting the amount of memory card slots used by half.

Memory card battle with only one card:
Enter memory card battle mode. A message will appear stating that player one is loading and that no memory card was found for player two. Wait until the information has loaded for player one, then remove the memory card and insert it into the second memory card slot. The game will load data from that location and allow both players to participate in the memory card battle.

Hint: 100 completion on simulation disc:
You can actually get 100% completion on the simulation disc. The "Event Synthesizer" that is unlocked by completing the Special License actually gives you percentage towards completion when raced. Be aware that the professional setting is actually a tournament and not a single race.

Hint: Easier turning:
When in a turn, hit the brakes until your hear your tires squeal. Then, turn with the D-pad.

Arcade mode bonuses:
The following items are awarded in arcade mode after winning each track. Note: They must be done in A, B, and C order.

Track	Bonus
High Speed	Autumn Ring
Trial Mountain	Deep Forest
Grand Valley East	SS R5
Clubman Stage 5	Grand Valley Speedway
Autumn Ring	Toyota cars
Deep Forest	Subaru cars
SS R5	The New Dodge cars
Grand Valley Speedway	TVR cars

Hint: Drive forever (demo version):
Normally, you can only complete two laps before the game stops. If you turn around and go the wrong way, you can drive as long as desired. Note: You will not be racing.

Glitch: Save money:
If you have bought a car and intend to apply "Racing Modification" and "Weight Reduction" stages one through three, perform "Racing Modification" first. Then, go into the "Weight Reduction" menu. If done correctly, when you try to buy any stage it will say "Finished Fittings For Racing Modification".

Glitch: More maneuvering room:
This trick is very helpful when in a tight spot and will work in both arcade and simulation modes. It is most noticeable in straight aways but takes effect anywhere in the course. When in a race and are surrounded by cars with no room to move, if you are on the camera angle where you are not in the car but the view that puts you closest to the car, switch to the view that puts the car farther away. All the cars (including your own) get smaller, however the track stays the same size. This gives you more room to make a move for a turn or to speed up and gain positions.
