V6 to 5.0 Coyote engine swap

[TexArmageddon]

Not exactly sure why everyone is so against it. Yes getting a GT up front will be easier but if you stick with new then it's not cheaper. A 5.0 swap can be done for around $7-8k as long as you find the right deals on eBay and are capable of doing the work yourself. I have been researching this for awhile. Once my 6 is paid off this is likely what I will be doing.

To answer your questions though, the trans, computer, exhaust, and drive shaft have to/should be swapped. While the internals of the transmission are the same from V6 to V8, the bell housing bolt pattern is different.

This swap would not be easy but it's not completely crazy as some would like to believe. Cheaper then a supercharger and you get a way better sound.

Unless you are plucking a 5.0 from a truck, Which is different from our stang motor internal wise.. Good luck with that 7-8k

In a previous post I explained that I would be getting an F150 5.0. And yes the F150 has shorter duration intake cams, slightly different intake manifold, and slightly lower compression at 10.5:1 vs 11:1. Those are not concerns though as I would upgrade to 350 cams and intake and the lower compression would be better for FI. $7k-8k was an estimate on the cheapest possible coyote swap into a V6.

Many people seem to think I am crazy here and thats fine. I will do what I want with my car!

The main point that many are completely missing is that I do not care about trade in value. I do not plan on getting rid of this car any time soon. If I ever did want to trade in the value stock for a V6 with very high milage would be minimal and not worth the effort. To me, having a car with all of the mods I have done and plan to do is much more valuable then getting into another stock vehicle.

The V8 is heavier so you will need to replace the suspensions and with the increase of power, the transmission and the rear end must be replaced. You will also have to replace the computer and all the wiring.
If some day you decide to sell it you will probably not get the money you invested in it.
I recommend you buy a nice 5.0 instead of modifying your V6.

Plan to have full aftermarket suspension at that time so it will be more like changing spring rates then replacing suspension. Brakes will already be upgraded to GT brakes as well. The rear does not have to be replaced. This isn't like the 2005 gen V6 where the GT had the 8.8 and the 6 had the 7.5..... All of the wiring does not have to be replaced.... Transmission does have to be replaced yes. The F150 6r80 seems to be the same as the mustang (provided its 2 wheel drive) Not sure about the drive shaft quite yet but that will minimal cost of it does need to be replaced. If I go manual it does get a little more complicated on the wiring front. Computer and engine harness is what will need to be replaced which if I'm lucky, will come with the engine. (Computer will need to be a 15 GT) Worst case the front harness will have to be replaced but not the entire car wiring harness. Yes there might be other small things that I am missing but people don't seem to be grasping the fact that these are mass produced cars..... Most of the components on the V6 are identical to the GT and as such makes the swap alittle easier. Again this isn't like swapping a coyote into a 05-09 as that gen was never designed to have the coyote.

I am not planning on selling this car period.... So people stop telling me to just buy a 5.0 instead. I have stated multiple times that A) do not want another car payment B) want to keep all my current mods and C) do not want to start over from scratch. I am not denying though that things might change within the next two years but as it stands now this is my plan.

You're going to have another car payment. How will you get around for the year+ that your car is in pieces?

Some advice from someone that has done 6 to v8 swaps and auto to manual swaps the only way to effectively do it is to have a doner car with the drivetrain you want which is going to be very pricey with a late model Mustang. Sure you can buy a v8 and tranny for $7 to 8k but it is all the other little things you never think about that cost money and take time to track down that will drive you crazy. You could easily spend another $2k before your done and have your car down for months.

Considering the cost difference between purchasing a v6 and base v8 is about $8k and the cost of a supercharger kit for a v6 is $4-5k those options make a lot more sense.

Every "fun" car I have ever owned I said "I'm keeping this car forever". Guess what? I've kept none of them.

If you enjoy this as a hobby and don't care about cost, labor and have the time, go for it.

My real question is if you are so sure you want to do this (as it seems from your posts here) then why even ask?

It is going to be very complicated and very expensive not to mention time consuming. Most would think this is a crazy idea so you'll need to be tough skinned to post a thread like this where 95% of the people will advise against it.

Good luck!:cheers:

The car will not be apart for a year.... And yes there will be another car payment for my other half which is precisely why I don't want one for another mustang payment .... :headbonk:

But again.... As I just stated.... Depending on my circumstances in 2 years or so I might just go ahead and get a GT. Who knows. Doesn't change the fact that my V6 is a project car that also happens to be my daily driver right now. I have already invested more in the car the someone who plans on trading in and I knowingly did so. Why is it such a hard concept to grasp that I am actually happy with the S550 as a whole and do not plan on getting rid of my current car?

Procharger is $7k for the 15 V6.... I could do a turbo 6 for cheaper using EB components but it doesn't get me the sound or the lower mileage V8 that a engine swap would.

I'm not the OP! I was answering the OP's question when I was attacked!! :lol:

Look, I don't think people are attacking you, but trying to save you from diving into something that I think we all assume you will regret. I don't think your idea is stupid, but I do think it's misguided. You mentioned that you will be doing the work yourself to keep costs down, so I am positive that car will be in parted for at least a year. You have to figure that you'll only be working on it on off time. Shoot, I think that would be a 6 month plus project for a competent shop.

Like I mentioned, I started the sports car world in a new edge V6. I loved the car to piece and thought I would have it forever. Others did the 4.6 swap and took parts from other models as well to keep costs down. It never went well. The power to cost ratio is nearly three fold the cost to make comparable power out of the current engine. I would anticipate doubling your initial budget and planning for over a year to work on it...I know you will disagree and that is fine, but this scenario isn't new so a lot of us have seen the results. I'm guessing you're younger like me, so I'd hate to see you financially strapped because of a project car gone crazy. You mention that cost is an issue now, but you'll be able to drop 10k (very conservative) plus a second car, more insurance, etc when you do this....but nonetheless, enjoy your car for now like I'm sure you are.

So no I will not have a stock no options GT at GT premium cost. I will have a GT that is EXACTLY how I want it with no monthly car payment. See the value now? Plus it will be a fun project as I enjoy digging that deep into a car.

Doesn't mean it will be the right way. You're overlooking suspension, brakes, wheels and probably few more things. Engine and trans is just a piece of it.

Overall - pretty retarded idea.

This isn't the 60's.........

 

[GTBOB]

Never understood the rationale of doing this type of swap. Just use the $8-$11K you are willing to allocate for the swap and put it towards the purchase of an actual GT.

Hell, what happens if you wreck the car after the V8 swap? Insurance isn't going to pay for "your value" of the swap.

Funny story similar to this....I used to be in the bagged mini truckin game LAte 80s to just recently), and this dude brought this Mazda Cab Plus back in maybe 91 or 92 to a show, bare metal body. He told me he started with a single cab and welded and Cab plus roof/skin to it, making his single cab truck now a Cab Plus...He was on and on about how much work was involved, etc. I looked at him real funny and asked him..."You know they already make Cab Plus Mazda Pickups, why not save the time and just start with that? He then looks at ME like I'M the crazy one...I think some people do off-the-wall stuff like that just so they can say they did it...makes for a good story...sometimes with a bad ending, but a story nonetheless....
