When do you really need to change your timing belt??? Is it 75,000 miles like most cars go by, or is it longer like 80,00-90,00???

i went all the way to 90k no problems, the dealer says i could go longer if i wanted too...

90k is about right for the 2JZGE. If you have never done a timing belt before, take it in. They are not easy to change and it is roughly $600. If you are off on the belt when installing the new one, you can cause great damage. There is a paper clip trick to know where the threading is when installing new, but I would have it done.

90 - 100k miles.

90k which is great for timing belt life. In comparison a mitsubishi eclipse belt is changed every 60k, and a porsche 944 is every 30k!

Pop the hood and remove the top timing belt cover. Inspect the belt for wear. Look at the smooth side for abnormal chipping, cracking cords, etc. Then carefully twist the belt to inspect the teeth. There shouldn't be any cracking of the rubber at the base of the teeth. Certainly note whether you are missing any teeth. If it looks like new and the rubber is holding up well 100K+ is no problem. Max life is probably 120,000 miles but for a safe margin of error Lexus recommends 90K miles. It's not a magic number that if you exceed 90K the belt will break. Belts have broken at 40k miles so if it looks good at 90K don't sweat it. Change it before 120k miles. Heat will deteriorate rubber the fastest second to chemical contamination.
