Turbo or engine swap?

I have a 99 v6 mustang no major mods just has dual flowmeter 40s. I know this is a pretty broad subject but I was curious about which would be the best bang for the buck I'm not wanting a 11 drag car but like a weekend racer or something along the lines of that. I have to rebuild the motor so I didn't know if I should just swap for a 4.2 and build that or put better internals in the 3.8 and throw a turbo or 2 on it? Any info would be appreciated.

What power figures are you wanting?

I haven't thought of exact figures nothin to crazy I was hoping for mid 200s I've heard nitrous but I'm not to sure about running nitrous so I didn't know if a turbo or motor swap would be best

Turbo or engine swap?

Buddy your low balling your car. in 99 the v6 got a split port intake, bigger throttle body, and better flowing heads = 190hp (40hp increase from previous year). You can go to late model restorations website they offer a CAI bigger throttle body with a tuner it would get your car to at least 210hp with that alone. Also maybe put some cams on it should get you to around 240 with long tubes.

Are you serious? I've looked at some other forums and everyone on them say 3.8s are bad to build cause you put to much in for to little gain.

I personally put headers and exhaust on one. It increased the hp to around 220hp with a tune. The 3.8 has potential (people just have a hard time finding it), the first step is to get the engine to breathe better. You have to look at it in a different way. Of course it won't make 4.6 power but it can make some. I wouldn't turbo it if you want force induction then I'd recommend finding a 4.6 and build that. It will be much more boost tolerant. I'm assuming auto? If you go to much power and not touch the trans it will break.

It's a good ole bolt action no point in having an auto in a mustang but that's just my opinion I was looking at some comp cams nothing to insane just some that increase torque and all the swap involves is cams and springs

Correct!
If you aren't emotionally attached to your car, or need to have a V6 for insurance reasons and such, you could just sell it and get a GT. They have the same horsepower that you would like and Ford was nice enough to have already built it for you. You don't have to do anything except find a nice one.

After you buy one, and post a similar question in the GT section, I'm going to recommend selling the New Edge GT and buying a Coyote powered car...

See how my mind works?

Your torque right now is 225 stock. With the exhaust you have now it's a little more. But the tune is key without the tune all the mods won't get good hp and torque gains. The tune provides max potential of all mods done to the car.

I like the way you think lol but it was the first car I bought on my own and ever since I was little I thought that the New Edge was hands down the best looking of the mustang along with the 60s fastbacks but I don't have couples 10s of thousands for a fastback so I'll stick with the New Edge

Alright did some research here's the verdict:
CAI and throttle body from late model restros
Mild cams
Long tube Headers don't put short tubes you will basically gain nothing.
Cat del if you haven't already
A good x pipe or h pipe
With a good tune you should make around 240hp maybe more. And that power shouldn't hurt the internals of your car. Also if you want to maybe take it to the strip then look into some wider tires for the rear and maybe a suspension upgrade for better launch and acceleration.

You might look into putting some better injectors on it. Maybe 39 lbs would be good, would help wake the car up more with the mod list I already gave. But tune tune tune the car is only going to be good as its tune is.

Haha.
I hear you! I like my New Edge also!
You can make decent power but it won't be cheap and you'll need some pretty aggressive heads, cam and an intake, just to be at bolt-on V8 power levels.
One of the forum members, DavidSeifert, has, probably, the most powerful N/A 3.8 on this website. Do a search of the members list and take a look at his garage.
He's on here pretty regularly so maybe he'll chime in and give you guys some pointers on building a mean little six banger!

Turbo or engine swap?

1. A V6 has a single cam not cams.
2. A stock car makes 150-155rwhp, you're not making 210+ from bolt ons.
3. A bigger tb is 0 gain especially on a stock motor where it's not even close to being a bottleneck.
4. If you go a full build NA (heads cam and ported lower with windstar upper) you can make upwards of 250 (current record is 278 rwhp), personally mine made 251 but has seen some changes since probably 260ish now.

Edit: injectors are a support upgrade not a performance upgrade, a full NA build will run fine simply on 24#'s

So in your best of your knowledge what would you suggest going with the swap or a turbo?

Way to much hassle to do a V8 swap, if you want that route by another car. Turbo ftw in our world, I'll be going the same path after I get done playing with my supercharger

I was looking into a 4.2 instead of a v8 I've heard people say that there's not much hp difference but a pretty decent torque gain
