Okay, so my last post was asking what I would need to do to get my 04 40th anniversary v6 up to a v8 of the same year and that's obviously not an option to me. So I had another idea. Would it be possible to say, go to a scrapyard, find a v6 of a newer year, and therefore a higher stock horsepower, and then put it into my car in place of the engine I have now?

Basically what I'm asking is, if I don't want to buy a crate engine, could I go find a totaled v6 from maybe 2007 and take that engine?

Are you expecting a "plug and play" motor swap? If so, this isn't it.

Just wondering. You are aware that there's a totally different OHC V6 modular motor in the 2005+ model year?

The PCM from a OHV V6 2004 will not run an OHC 2005+ OHC. What do you plan to do for engine management?

Are you also aware that the 2005 modular OHC V6 will not bolt up to your existing transmission?

The 2005+ modular OHC V6 is closer the the 4.6 V8 than it is to the OHV V6 as they both are modular motors. So this swap will also need a modular K-member.

What are your HP goals and budget?

Superchargrr

A supercharger (Vortech, Procharger) would get you more power than a GT, but it would cost about the same as it would to just upgrade to a GT.

The newer engines are completely different and will not swap in. They are also barely any more powerful than what you have now.

Might consider something like this.

High Performance Ford 3 8 Mustang 4 3 V6 Stroker Engine | eBay

This should bolt right in, will need a tune, have not used one, so I can't say about the quality, just sounds like a neat package, might be worth looking into.

You aren't going to get the full potential out of that thing without several thousand in supporting mods. By the time all is said and done you will have spend twice the $ as a used supercharger system for far less power.

$2700 stroker longblock
$200 for freight
$350 core charge
$400 SCT handheld
$500 dynotune labor
+ported intake
+bigger injectors
+bigger throttle body
+full exhaust
+gaskets
+fluids

.... you get the idea

As wmburns said, the 4.0 is completely different than the 3.8 in every aspect. A supercharger is a good way to go... if you have 4000+ dollars for a new procharger kit, since vortech discontinued new kits. The thing I would do, like I did with my motor, is go with a nice cam, rockers and springs from SuperSixMotorsports. About 1500 dollars for the kit I did including gaskets and the windstar intake swap. 249rwhp plus a great idle. Well worth the cash in my opinion.

Okay. Dang... I didn't want to do supercharger, I was gonna go for a fast and light kind of deal and try turbos with a little weight reduction here and there. Does anybody know how to begin rebuilding an engine and improving on it? Like say I go get the same engine I have now from a scrap yard and rebuild that (since I can't take the engine out of my every day car) what would I need to do to it to get better kick out of it? Does anybody have suggestions as to mods I can consider? I'm looking to keep this car for a few years so putting money into it is kind of a given, just don't go too crazy

 

[jackx429]

If I did cam, rockers, and springs, what exactly do those effect?

 

[6stang02]

Cam and rockers affect the duration the valves stay open and the time it takes from one to open to the next. It improves air flow and exhaust flow, allowing your motor to perform better. First hand experience with the "lumpy" cam from SSM it is a mean and deep sounding v6. It carrys the power all the way through the rpm range, to 6000 which I my redline, as well as a quick acceleration. If I put it into first gear, automatic, it takes me roughly around 4-5 seconds to get up to forty. At about 4000 rpms, then shifting it into second it chirps both my tires with my open differential. The only mods on my v6 are the windstar intake,cam, rockers, springs, pushrods and a tune from American muscle. While you are in the motor I recommend replacing the timing chain and tensioner with one from Ford. Its about 20 for the timing chain and 20 for the tensioner I believe. Remember the only thing that the engine wants is to get the air in the engine and out the engine as fast as It can. Dual exhaust is something I recommend with a chambered muffler, Not a glasspack. Flowmaster makes some that sound great on the car. I have the flowmaster 44 series on my motor with an x-pipe. Great for a stock motor, keeping it quiet and such, but I wish I had gone with the 40 series or the delta flow 40 series originally.

Also when it comes to turbos vs superchargers.. id go with the supercharger.. because the power Is always there, you dont need to have it spool up for your power gains. Now the supercharger would run off the engine but it barely takes away from the Hp. There is a built v6 that was on YouTube pumping out 447rwhp I believe with a supercharger. But go with what you want, plus a turbo would also have to have custom exhaust piping so think about that also when it comes to cost.

To echo wmburns...What's budget and goal for the car? Mechanical ability?

 

[metalman302]

A supercharger is a good way to go... if you have 4000+ dollars for a new procharger kit, since vortech discontinued new kits.

If a GT is out of the question, I'm guessing a $4k Procharger kit is too? Used kits pop up fairly regular. I've seen anything from a bare bones Vortech kit for $1200 to a Procharger kit with fuel mods for $2k. I also occasionally see a used Vortech bracket only... that's the critical part... you an piece together the rest.

If you have a hardtop and a stick shift then that's about as light as you can hope for already.

You have turbo's in the budget? Please tell me you aren't looking at those ebay scam "kits" which are nothing more than a couple junk turbos and some general piping, nothing is specific to a mustang at all. A real turbo kit costs about $4k and a used one would usually go for around $1500.

Rebuilding an engine doesn't make it make more power. Upgrading everything inside and outside the engine does. Upgrading to stroker crank, higher compression pistons, shaved heads for more compression, bigger camshaft, then of course you need bigger exhaust and bigger intake manifold etc or else the other improvements will just be bottlenecked.

The only option that resembles what you are hoping for is to find a used 4.2L truck motor and swap that in, but it's still a ton of work for hardly any gain from the motor alone. It's a bigger motor but with the same heads, roughly the same intake and cam... it only makes 9 more hp and 32 more torque..... not worth swapping engine for that!

You already know you're going to get rid of the car in a few years... that's just another reason for a supercharger because then you can take it off sell it separate and get your full value back from it when you sell the car.

 

[metalman302]

He was talking an engine with higher stock HP, so i wasn't thinking supercharger and I was just giving him an option with one that would bolt right in place. He could use as much of his stock stuff as he could and then if that's not enough he could always add the headers, ported intake, larger throttle body, ect later, he would need the handheld and tune no matter what.

Still a horrible idea...

That engine has:
bigger valves
more cubic inches
barely higher compression
barely bigger cam (smaller than the smallest SSM cam)
NON ported heads

$3250 just to get that shortblock to your door, and with with what is listed it might make about 20 more hp than a $500 used junkyard F150 4.2 engine

I am speaking from personal experience as someone who did swap in a $500 junkyard 4.2L with only 50k miles on the engine, and it was barely any faster. After fluids, gaskets, and tuning I was over $1k. In the end it was a huge ******* waste of time and money and I was without a car for months.

 

[metalman302]

Stock 4.2L bottomend, Longtube headers, RPM Gen1 BV Heads, 207/215 camshaft, Stage 1 Lower and Modified Upper intake, MAC CAI, Dual Magnaflows w/ X-pipe, UD Pulley, 70mm TB

(Big valve ported heads & intake manifolds with extensive cutting, porting, welding)

When your intake and heads are hugely improved, the cam doesn't need to be as big. For example on my foxbody 5.0 I made 287 rwhp with good intake and good heads and stock cam.

Stock cams are not given credit where credit is due most of the time. I know my b-cam is going bye bye for the stock cam when my garage gets warm enough to work in.

Why downsize if it's already installed? I could be wrong but isn't the B cam the small one like barely bigger than stock?

 

[b1lk1]

Had a lifter retainer snap and in turn a lifter spun sideways and probably (not verified yet) wiped the lobe out. I gotta put new intake gaskets on it anyways, gonna scope the 2 lobes that could be effected first.
