Continuity mistake: In the scene where Brian is chasing Johnny Tran, he stops the car and shoots Johnny. Johnny spins out and falls off the bike. While he falls off the bike you can see a shopping cart on the side of the road, but when Brian runs over to see if he is dead, the cart is gone. (01:34:15)
Continuity mistake: In the scene where Dom is pulling his red RX7 into the garage after the first race is broken up by the cops, he is making a right turn into the garage. When they cut to the front of the car pulling in the garage, his left signal light is on, meaning he made a left turn into the garage. (00:23:59)
Other mistake: When the first trailer/truck is hijacked and the harpoon is shot in through the window into the seat, you can see the driver is very clearly looking out the side window next to him instead of looking at the hijackers in front of him. It's almost as though he doesn't know that the others are there! He also looks incredibly relaxed and not at all worried about the fact that a guy is climbing up a rope into his cabin when there is a lot of expensive video equipment in the back of his trailer. (00:01:53)
Factual error: Brian tells Dom that hector is running spoon engines with T66 turbos and a motec system exhaust. Spoon engines are typically 1.6L and are a terrible drag racing choice, also a 1.6L engine cannot properly spool a T66 turbo as the exhaust gasses do not have enough pressure to effectively spool the turbo.
Continuity mistake: At the end of the film when, Dom knocks the Chinese guy off of his motorbike. In the previous shot if you slow it down you can see that it's a street full of houses to the left and right, but these suddenly vanish and are replaced by a big hill which the Chinese guy rolls down.
