"Take it to Vinny" is meant to be sarcastic. Vinny is the owner of a good but erroneously overpriced performance shop in Long Island, NY. Vinny knows his stuff, but he is super expensive.
$19,000 for a 500whp build but you have to buy your own turbo kit, who the hell is he kidding? LOL.
Ques: Yo man, my motor blew up, what should I do?
Ans: Dude, just take it to Vinny, he can set you straight.
Ques: I want to build my motor and boost it, do you know any shops?
Ans: Yeah, do what everyone does, get a loan against your house and just, take it to Vinny.
