Factual error: "Fast and Furious" [4th film] takes place after "The Fast & the Furious" and before "2 Fast 2 Furious. However there's an R35 Nissan Skyline in the film, which didn't exist at that time.
Suggested correction: Fast and Furious doesn't take place before 2 Fast 2 Furious. The opening sequence takes place before Tokyo Drift, the rest takes place in 2009.
This entire film (as well as the next two after is) take place before the events of "Tokyo Drift." The beginning of this film, taking place in the Dominican Republic, takes place not too long after the events of the first film, probably around the same time as the events of "2 Fast 2 Furious." The rest of the film takes place quite some time after the events of "2 Fast 2 Furious." It is the 7th film that catches up to and continues after the events of "Tokyo Drift."
