Join Date: Jun 2007 Location: Durham, NC Posts: 327 | Mustang V6 SOHC to DOHC Conversion? What is involved in this conversion? how much additional power would we be talking about from the 08 Mustang? I am looking to get one maybe, it would be a huge step up in power in relation to my focus I have now
any advice on this? | |

If you want a power bump, switching to a more aggressive cam profile will give you all the power of a DOHC swap with a slightly lumpy idle and slightly worse gas mileage.

would never be worth the $ you put in to it(if you could even do it)
the nice thing about the rustang is the great aftermarket for it
start adding bolt-ons and go from there till you get the power you want
or run out of $  | |

Oh I wouldn't I dont have deep pockets  I was just wondering what was involved...I would just save up and get the GT model....I was asking because someone else asked here where I work, I told them the same thing, just get the V8......From what I have read already it WAY to much to do the dohc / turbo setup vs get the v8 and turbo that... | |

The 4.6 is a modular over head cam engine. It comes 2v as a GT or 4v as seen in cobras and mach 1's If your planning on swapping a 2v for a 4v, you really need a 4v engine to pull the parts off of, even up to the wiring on the engine, you need to swap it with 4v stuff! | |

The 4.0's are indeed pushrod engines, however, mustang GT's since the most recent redesign have the 4.6L mod motor with 3 valve heads and variable valve timing (hence the bump from 260hp to 300hp in the 2005 model year.
Switching to a 4v would make no sense, since the 4.6L DOHC really didn't make any more power than the current 3v.
You want more power out of a 4.6? Supercharge or don't waste your money. You want more power out of a 4.0? Trade it for a GT or don't waste your money. | |

It's not cheap considering you're pretty much replacing half the engine. SOHCs work great turbo, your power yield is a lot more significant going this route than most NA routes. | |

Top swap won't cut it, i'm afraid. And, as i mentioned before, the 4.6L 3v VVT in the 05+ GT's is as good as the 4v motors ever were. The way to go with these motors is a blower. | |

Modding a V6 Stang to make it faster is kind of a losing proposition (no offense), as others are saying here. The V6 is made for people who just want an all-show car and couldn't care less about performance.
The GT has modding potential. Or better yet, rewind a few more years and get a Cobra heh
