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?

Re: Mustang V6 SOHC to DOHC Conversion?

You're talking about buying an '08 (new) Mustang and converting it from SOHC to DOHC?

Heh, that's probably not a job you want to get involved in. 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.

Re: Mustang V6 SOHC to DOHC Conversion?

the power you got out of it
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 $

Re: Mustang V6 SOHC to DOHC Conversion?

Why would you do all of this to a V6 (and void your warranty) when you could just buy a V8?

Re: Mustang V6 SOHC to DOHC Conversion?

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...

Buddy, the 4.0's are pushrod engines, there is no 4v version!


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!

You're almost correct. 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.

Re: Mustang V6 SOHC to DOHC Conversion?

If the block is similiar enough, swapping from SOHC to DOHC would require a head change. This is done with many Hondas as well. 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.

Despite the fact that ford calls them modular motors, they're not particularly "modular"

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.

Re: Mustang V6 SOHC to DOHC Conversion?

Try looking at 07 GTs? 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
