Super Racing Muffler
Clear the second season then race the hatchback event. If you raced the hatchback event before doing so, you may not perform this trick correctly. After you clear the second season buy a Civic Type R 02 and fully modify the car. Race the hatchback event and come in first.
Nitros
Go to the used parts section regularly and check for question marks. For $1800 you can get a bottle of Nitrous Oxide, only for use in Drag Racing. To use it, press Y. Use wisely, as it is one-time only. Note: This was done with a play time of 24 hours.
Nitrous Oxide Part
To obtain nitrous for the drag race you must be on a day ending in a 6 (26, 86, 236, etc). You must first lose a drag race at least one day before the day ending in a "6", or up to 3 days in advance (ends in "3"). Once you have lost, and it is a day ending in a "6", go to the used parts shop and the part will be all the way to the right under the "???". The part costs $1980 and you can only use it once (by pressing Y button) in a drag race.
Easy money
Unlock the GT40 Concept car from the Season 1 Official Races. You can buy it for $150,000 then sell it for $185,000 to $195,000. It only takes about one or two game days to sell it, for a $35,000 to $45,000 profit.
Quick start
Get a six gear car. Top it out with the maximum HP, ten test it out in the Sega Drag race. Make sure you get your car in a Manual Transmission. Start out with sixth gear, and accelerate just before the last second. When you go up to 40 mph, shift down to third and make your way up the gears.
Control replay views
You can control the camera during replays. In "main view" mode, use the Left Analog-stick to move it up, down, left, or right; and L and R to zoom in and out.
Faster drag race
During a drag race turn your TCS (Traction Control System) off at the options menu. You will notice your car is much slower with it on. Just let the wheels spin and you will get a win every time.
Free part/upgrade
Purchase any part/upgrade for any car and have the exact amount of money in your total money. You will receive the part/upgrade for free. For example, have $10,000 total money and purchase a Tuned ROM upgrade priced at $10,000. You will get the part for free with $10,000 still in your total money.
Get Ford Dragster
When you're in the garage press white, left, right, white, left and you will get a 1967 Ford Dragster.
Nitrous
To get the nitrous from the used parts shop, you will have to lose at the drag races on a day ending with "5". For example, 305,15, etc. Return to the screen for the parts shop after the drag race. It will now be 306,16,etc. There will be a question mark at the end of all the parts, after the turbos. If your car has a turbo or if it does not appear, get out then go back in and it should appear.

Reverse burnout
Go to the options and disable the TSC. Then take your car for a test drive. Try to get in the middle of the track and spin the tires. You can turn right or left.
Burnout
Go to the options and disable the TCS and SCS. Go to your garage and select a car to perform a test drive with. You can now do a burnout and donuts. Hold X + A to burnout for a long time. It takes a few seconds for the car to stop moving while holding the buttons. In quick battle mode, if you select dual race only player two can do burnouts and donuts.
Accelerate faster
To accelerate faster during a race, tap R. Note: This will only work with an automatic transmission.
Third turbo
To get the third turbo, win the "Monster B" race in the second season. There is an easy way to win it, that requires about thirty minutes. First, get a Nissan Skyline R34 V-SPEC II and build it up to the max. Set its suspension to soft on both and
set the boost pressure to maximum. Make sure TCS is on. Win the last event race. You will win a car. Build that car up to the max. Set the suspension to soft and boost pressure to maximum. Turn TCS off. Before you buy the Nissan, it would be
wise to sell an expensive prize car for double its price. It will take about ten to fifteen days to sell it. If it lowers the last number of its price on the left down one number, you are set.
Cheaper parts
Enter the used parts menu, select a part and check the price. Exit the screen and repeat a few times. The price may drop down by a couple hundred dollars. Go to the used parts menu, and look for your part. They will usually be cheaper, sometimes even up to half off the normal price. But be careful, for these items will often break in the middle of a race and cannot be repaired.
