Fast & Furious (2009) - 2 questions

Question: What is the exact timeline for this movie? Is it taking place at the same time that the Tokyo Drift is taking place? Or is it supposed to be before?

Answer: It's a slightly tricky one to answer because the movie doesn't give very many clues. What we do know for a fact is the events at the start during and up to the conclusion of the Petroleum tanker heists was set before Tokyo Drift as evidenced by Dom speaking to Han with a view to returning back to Tokyo. After that it gets a little fuzzy. Some people claim the entire movie is before Tokyo Drift, but that simply cannot be the case as there are lots of 2008/2009 model cars around the movie, so the general consensus is the very start is before Tokyo Drift, and the time when Dom comes out of travelling/hiding and gets the phone call that Letty is dead is now after Tokyo Drift.

Question: Are they completely ignoring the events of the second movie? I was given the impression that Brian and Roman were going to open a garage together with the money they took from Carter. Plus Brian was on the outs with the FBI. Yet in this movie, he's suddenly an FBI agent.

Answer: No it doesn't ignore 2 Fast 2 Furious, Brian even references it a couple of times. In that movie, Brian was promised a 'clean slate' if he helped them out which presumably gives him the option to rejoin a law enforcement agency. That he chose not to open a garage with Roman is pretty much redundant, Brian simply got a better offer, and as he stated in Fast & Furious with his conversation with Mia, "I'm a good liar".
