Hi can someone tell me if its possible to do an engine swap for the 04 V6 mustang 3.9 liter with an older (around 2000) cobra engine? If so how would i proceed with this?

Thanks

I have no idea although I would like to know the same answer although I want to trade my friends dads GT late 90's engine for my 04 v6. Sorry for off topic but this seems like a good post.

It will bolt right in, referring to the first question. But..you will need to upgrade your suspension if you put this much power in. Your stock suspension and frame system is not built for that much power. If you're seriously thinking about this, I'd start by working on your suspension and frame first.

Also, if you decide to go with an engine swap, you'll need :
Engine
Computer
All wiring harnesses
New tranny most likely
Driveshaft
Rear end

And that's the short list...

hmm the cobra only puts out around 300ish hp tops.

i've seen plenty of v6 engines handle well above this with stock suspension setups. (including mine in less than a month)

Just get a 5.4 out of a Lincoln Navigator, DOHC 5.4 V8, perfect engine right there, same thing that's in the Cobra R

a 2000 cobra engine and a 2000 cobra r engine are different.

the 00 cobra used the 4.6/281
the 00 cobra r used the 5.8/351

the 00 cobra engine will fit right in but will take atleast all the stuff as lowflyn said

Unless you get a new hood the intake system is to tall. you really need a 2000 Cobra R intake

Correcto Mundo!!! The problems with the 99 Cobra's lack of HP was a big enough concern they recalled them and skipped the 2000 year cobra

Yup, there was no 2000 cobra, just the 5.4 cobra R

well how about this then, instead of a cobra engine.....would it be easier to put in a 2003-2004 Mustang GT engine? If so how much easier are we talking.

Thanks for your help

Why don't you just sell your car and get a GT?

It's gonna be a lot cheaper in the end...And a whole lot better on your self if, god forbid, you get into an accident and the insurance company "doesn't know" about how much you've invested into your "v6".

As already noted theres no 00 cobra engine. Second are you planning on doing this swap yourself or paying someone?

I dunno I just have the feeling that most people who suggest doing a swap thinks its just that and dont realize all the small minor key things that end up being expensive to make the swap work.

Its just so much easier to just buy a cobra or a gt and if you say cause of insurance reasons then what you plan on telling them if something were to happen to the car, you'd be 100% f*cked if insurance found out and you'd get no help and more then likely dropped.

unless you report to them all you've done to the vehicle with receipts up front, as soon as you're done.. there are companies who will reimburse you some %age of that as long as they agree from the start

yep and you know how much insurance is gonna rape you on rates once you do that. I did that with my old system and I still ended up getting screwed in the deal.

I hate insurance companies when it comes to "aftermarket"
