Brian O'Conner, now working for the FBI in LA, teams up with Dominic Toretto to bring down a heroin importer by infiltrating his operation.

Brian O'Conner: I lied to you. I lied to Dom, I lied to everybody. That's what I do best. That's why the feds recruited me.
Mia Toretto: Maybe you're lying to yourself. Maybe you're not the good guy pretending to be the bad guy. Maybe you're the bad guy pretending to be the good guy. Did you ever think about that?
Brian O'Conner: Every day.
Dominic Toretto: It starts with the eyes. She's gotta have those kind of eyes that can look right through the bullshit, to the good in someone. 20% angel, 80% devil. Down to earth. Ain't afraid to get a little engine grease under her fingernails.
Gisele Harabo: That doesn't sound anything like me.
Dominic Toretto: It ain't.
Brian O'Conner: You asked me why I let Dom go. I did it, because at that moment, I respected him more than I did myself. One thing I've learned from Dom is that nothing really matters unless you have a code.
Mia Toretto: And what's your code, Brian?
Brian O'Conner: I'm working on it.
[after preventing Brian from passing him during a race]
Dominic Toretto: Still a buster
Brian O'Conner: She did it for you, Dom! She did it for you. Letty came to me to clear your name in exchange for bringing down Braga. She just wanted you to come home!
Brian O'Conner: Ya know, I've been thinking, when you blew up your car, that means you blew up mine too.
Dominic Toretto: Yeah?
Brian O'Conner: Yeah, so now you owe me a 10 second car.
Dominic Toretto: Is that right?
Brian O'Conner: Yeah.
Dominic Toretto: [breaks window to Subaru WRX Sti] Now we're even.
Agent Sophie Trinh: [reading list of cars driven by possible suspects] ... Toyota Prius Hybrid...
Brian O'Conner: Hell No.
Agent Sophie Trinh: So which car do you want?
Brian O'Conner: All of them.
Dominic Toretto: I'm a boy who appreciates a good body, regardless of the make.
Brian O'Conner: What I did to you was wrong. I'm sorry, it was the hardest thing I ever had to do.
Mia Toretto: I'm sorry too, Brian. I'm so sorry that you had to come into my home and pretend to love me. I'm so sorry you ripped my family apart. I'm very sorry that that was hard for you.
Dominic Toretto: "Pussy"
Brian O'Conner: Sorry Car!
[Goes over the fence]
Dominic Toretto: Hey... boss man...
Fenix Rise: What did you say?
Dominic Toretto: I said... only *pussies* run nitrometh...
Fenix Rise: [incredulous] You looked under my hood?
Dominic Toretto: A real driver knows exactly what's in his car.
Agent Sophie Trinh: How do you know?
Brian O'Conner: Because that's something I'd drive.
Brian O'Conner: This is where my jurisdiction ends.
Dominic Toretto: And this is where mine begins.
Mia Toretto: How do you say goodbye to your only brother?
Dominic Toretto: You don't.
Fenix Rise: [after Dom won the race by "cheating" Brian] That's what I call a real driver.
Brian O'Conner: [angrily] No, that's bullshit man.
Fenix Rise: Yeah, yeah, go cry to your mama.
Brian O'Conner: A lot has changed.
Campos: [as a toast previous to drinking a shot] To the ladies we've loved, and the ladies we've lost...
Penning: Stasiak, go get yourself cleaned up.
[... ]
Penning: You're bleeding on my floor.
[last lines]
Judge: I've listened to the testimony, and taken into special consideration Agent O'Connor's appeal for clemency on behalf of Mr. Toretto... that his actions directly resulted in the apprehension of known drug trafficker, Arturo Braga. However... this judiciary finds that one right does not make up for a lifetime worth of wrongs. And as such, I find that I am forced to level the maximum sentence under California law. Dominic Toretto... you are hereby sentenced to serve 25 years to life at the Lompoc prison system... without the possibility of early parole. This court stands adjourned.
Brian O'Conner: [Brian is injured and they're waiting for help to arrive] I gotta ask you something.
Dominic Toretto: Yeah?
Brian O'Conner: You know I woulda, I woulda won that race if you didn't cheat right?
Dominic Toretto: You hit your head hard.
[first lines]
Dominic Toretto: [on a walkie-talkie] All right, we're good to go.
Dominic Toretto: [to Letty] You got this?
Letty: You bet your ass, bubba. Let's make some money!
Brian O'Conner: [when asked whether he got a lead for the on-going case] I got a name. David Park.
Agent Ben Stasiak: That's it? A name? I could throw a fortune cookie and it will go through the window of 50 David Parks.
FBI Agent #1: [about the name] It's Korean. Not Chinese.
Brian O'Conner: It's nice to see you've gone with the times and switched to electronic fuel injection. Looks good.
Dominic Toretto: Buster became a gearhead.
Brian O'Conner: Well the good news is, when we get this guy, you walk out of here a free man.
Dominic Toretto: Is that what they told you?
Brian O'Conner: Yeah, that's the deal.
Dominic Toretto: Do you still put milk and cookies out for Santa Claus?
Dwight: [Dwight is filming three women making out at a party] Papa Dwight wants you to take off your shoes! Dwight loves feet!
Mia Toretto: Let this go. Before it's too late.
Dominic Toretto: It's already too late.
Letty: This is all you, Han!
[Letty smashes the end of the truck with a hammer]
Letty: Liquid gold, ha ha!
Han: [through the walkie-talkie] I thought we'd be robbing banks by now, not some gas truck in the middle of nowhere.
Letty: Down here, gas *is* gold, bubba!
Brian O'Conner: [after Dom wins by spinning Brian's car] At least we know you can't beat me straight up.
Dominic Toretto: I didn't know there were any rules.
