Break the sound barrier in GT
Select a 4WD car. Start and get some speed. Hit a wall at 90 degree. Hold the throttle open. Now your car is stopped, wheels spinning and smoking. Slightly steer to whichever you want to go. Suddenly your car is accelerated. Try to keep your car sticking to the wall so that the acceleration continue.
Double Your Cash and Garage Space
It is understood that your garage in Gran Turismo 2 only holds 100 cars at a time. Lets say you have 100 cars and $10 million credits Save your game play twice on two differants memory cards. Use one card as your primary garage and one as your secondary garage. Now take the first card and sell off all the lower cars then safe agian. Now take the secondary card , load up and sell all the higher cars then safe again on the secondary card. Keep your best race cars on the primary and all others on the secondary. You have now double your garage space to 200 and have doubled your credits with 10 million in each , plus what you got for the sold cars for a total credits of 20 million plus whatever earned on sold cars, split between the two garages. If you need to transfer a car from one garage to the other, use the data tranfer mode off the main menu by buying the cars off each other You will never lose the money for you own both garages. When one garage fills up, do it again.
Easy Money and Cars
First,you must have at least 300,000 now and an I-A liscense. Buy a Mitsubishi 3000GT MR-Twin Turbo and tune it to the max. Go to Special Events and enter the No#1 Tuned Turbo Car World Cup. All the races here pay 50,000, but are kinda hard. Pick the one with the Test Course. The cars here are unforgiving so make sure you tune your car to go to at least 210 MPH. Race 3 consecutive times and you will win the second ultimate car the HKS R33 Drag. Which sells for 250,000.
Eight Tracks
Go to Arcade Mode and enter the "Bonus Items" option. You should see the letters A, B, and C above each of the levels given. As you do the following, they will be covered with a blue, yellow, or red dot. To fill in the four big question marks, go back to the main Arcade Mode screen. Then, go to "Single Race", choose any difficulty level, and place first in each of the four original levels with an A class car e.g., Mitsubishi GTO, a B class car e.g., Mitsubishi Eclipse, and a C class car (ex: Honda Civic 3-Door). After you have done this, go back to the "Bonus Items" menu and the four big question marks should be filled in with these levels: Autumn Ring, Deep Forest, SS R5, and Grand Valley Speedway. That totals eight tracks.
Extra HP in HP limited races
On the simulation disc you can use a car with up to 5 more HP on the races (with limited HP). Go buy a item such as race mufflers or computer, but do not equip them on the car. Before the race go into settings and equip the item. The computer will allow around 5 HP more than posted.
Fast Money
First get every lisence up to international A. Then go to mazda used cars and buy the one which is the most expencive (for under £10,000. The colour for the car is brilliant black). Then go and win the first race of the Sunday Cup until you get £25000-£27000. Then go to Mitibishi used cars and buy the blue lancer. Then go to Muscle Cup under special events. Win the first race around 3 times and you win £7000 each time. But you win a car which you can sell for £25000. Now tune your lancer with all the things which gives you more speed. Now enter the second race of the Muscle Cup. Here you win £8000 and a car which you can sell for £75000. Win that 7 or 8 times and you have yourself with over £500,000! Its easy if your as good as me!
