 Subject: no more 3.9L power problems!!!
IP: Logged
Message:
Well i guess the only way to get real power from your 3.9L is to get ride of it. I swapped it out for a 5.9L today and now I have a real truck. Its a 97 dak with an automatic.I thought that this was going to be a hard swap but really it's like the truck was waiting for it to happen. For those who have the v6, think about getting a 5.9L. Its only cost me about $800( I do my own work) and it was a very easy swap. Used all my original parts except fan shroud,and pcm and had to wire in the extra 2 injectors.I started at 8:00am and was done by 4:00pm (again,I work on cars for a living) Everything bolted right on to my trans,exhaust,accessories, oh, and new rad hoses. I tell you what, its like i bought a new truck. Jst thought I'd let my fellow dak owners know how simple the swap really is.If I can help any other HP neglected v6 owners do this swap I'll be glad to give a hand.

I bought a V6 for specific reasons and enough horsepower to out run a Camaro was not one of them. I have never felt under powered as I use it as a go to work car and a truck to haul things in, not as a "Race car" In the city I live near going fast is not an option as for some reason Everyone goes about 5 or more MPH Under the speed limit, so why would I need super quick 0 to 20 mph times? Just so I can hit the guy in front of me bumper faster? AS long as my truck gets 23 MPG on the hiway and will easily run 20 MPH over the speed limit, I need a gas sucking V8 for?

mines bigger then yours and has produced more kids then yours.
I don't hug trees but I shoot idiots out of them. you seem like an idiot.
swapping a small stock engine for a big but still stock engine is not a performance gain it is mearly engine swapping.
if I can go out and buy it off the show room floor. and chose, too instead of doing all the work PLUS buying a truck AND a second engine for it, doesn't that seem like a waste of money? plus you have to get rid of the smaller engine, which no way will it bring in as much money as the new one cost. and that will cost you sooner or later. The only time such a swap makes sense is when the old engine blows up and you get a deal on a really low miles and well maintained (yeah right) engine that is bigger then stock.
Some times I like to troll around on here and see how many of you do things that really make no sense and, well, swapping a 6 for an 8 makes none. better to sell the six and buy an 8. Unless of course you have a bad caas on penis envy and want to swap mine for yours. and that aint never gonna happen.

Does it seem ignorant to purchase what you can afford and upgrade so you don't have to masterbate into a cup twice a day to make the payments? If I could buy a 4 cyl. 94 Dakota Sport, in good, condition for $1500, then purchase a crate motor for $3000 which makes 380HP out of the box, why not? It's better than buying a 94 318 with 100,000 miles for $4500, packin' 190HP because the idiot that owned it before changed the oil every 8000 miles at best!
To each his own! Don't blame Todd because you couldn't figure out how your wife kept getting knocked up and you now have nothing better to do than to go on a message board, like this one, and piss on other peoples dreams because you can't afford dreams of your own. If that's not penis envy, I don't know what is!!
Spit that penis out that you mentioned swapping for mine and get a hobby! Nobody here cares about what is logical or economical. We are here to share ideas about how to spend money on a truck, that we know isn't a sports car. One that we will never get our money back out of or be satisfied with. But most of all, one that will wake your minivan full of kids up at the redlight and possibly moisten the loins of your wife one last time before you bore her to death with your "logical" life.
Work hard.... Play HARDER.... and F**K the ones that don't understand why you're doing it!

the whole idea of a performance forum is to discuss performance! If the only reason you morons respond is to crap on someones parade well do it elsewhere or go back to slapping your wives around or something.I posted this to let others know(who are interested in getting a 5.9L into their trucks) how easy it is.And why would I sell my truck,that I have spent thousands of dollars on, to buy one with a v8.Talk about not making any sense! Besides my truck is only a weekend ride. I only use it to go to truck clubs and cruises.Gas milage I could give a crap about.I make plenty of cash to afford gas for my rides.And if your more concerned about gas milage than the pleasure of driving, well then custom rides are not for you. You may as well ride the bus! And to the man who responded about the vibration, no there is'nt any because the flexplate has the counterweights on it already.I did buy the weights for the torque convertor thinking I had to use them but when the motor arrived they were already on the flexplate.

There you go, Daktobasics, a guy who understands what being a man is all about.Bigger, faster,more powerful,and still not good enough!! I put the engine in stock just to get it to run with the 5.9L, then I'll move on to upgrades later.First thing is to work all the bugs out. I already have an M1 intake,cam,and heads for it but first I want to blow up my V6 tranny.

Hey Todd can you tell us how you altered the stock wiring
harness to work with the 8? I'd be interested in hearing what
was involved in this swap out. Sounds pretty cut and dry to me I
just don't know what you had to do electrically.

a. mark,
one way to do it (which is what he probably did) is to run new wires in the pins on the wiring harness. Just because you dont have the wiring for the two extra cylinders, doesnt mean the part that plugs into the computer doesnt have room for it. I forgot which pins they were, but you just have to run a wire from each pin (19 and 20 i think.. but dont bet on it).. then you can ground the other wire from the injector to the other injectors.
I kinda went with uh Dakto?,
i didnt want to drop in a motor that i could just buy the truck with... so i got a big block instead.

A 97 v6 wiring harness is identical to the v8 5.2L for that year ONLY!! The only thing is to run wires from connector B-2&B-13(injector 7&8) on the pcm.Then rob the power inputs from the injectors directly next to each injector. Hardest thing is to tap into the pcm connector. my suggestion is to go to the junk yard and find a similar style pcm connector and steal 2 wires out of it.The actual wire connector in the dak pcm is hard duplicate.I used one out of a junk intrepid that was at my shop. Then the next step is to get a pcm that will run a V8. Again I used borrowed one out of 97 Ram that was also being worked on at my shop.Only temporary of course. Thing is it won't communicate with my BCM. Nothing on my dash will work at the moment.The fix for that is to have the pcm I will be using (mopar performance pcm) have the vin # written into it. That is what makes the 2 be able to communicate with one another.I'll have that done when my pcm arrives.Unfortunately I have to take out the pcm and give it back to the Ram. That sucks, I'll only be out of my truck for a couple days but it still really sucks.So I'll be sure to tear the streets up on the way to the shop tommorow.

And by the way intensedak is right on except the injectors always have power to them, the pcm only sends impulses of ground,which makes it squirt. And yes is was very cut and dry. 8 hours TOTAL!! 95% of the parts are able to make the swap.

That was so eloquently said that it should be permanently emblazoned across the home page of this website.

UH,
V6's are for little old ladies and pussy wipped husbands that don't really use trucks for trucks. Not everybody that buys a truck does all their driving on a 35mph access road. Some of us actually have a use for a truck, like pulling a 4,000lb trailer. Why did you even buy a truck? Sounds to me like you need a Civic.

Not you, Wip. I was referring to the tree-huggers doing thirty thinking they're gonna save the world. I drive power-limited vehicles too. Sometimes they're almost more fun because you're running so hard trying to get every last ounce of power. It is often said that the most competetive Mopar racers are the slant six guys for the same reason.

Careful there Whiplash about the v6's. Larry from J and J Auto has a v6 in his 95 4x4 Dakota that at last dyno run put out 267 rear wheel horsepower. He can run circles around most v8's, his truck is highly modified, but normally aspirated. He's pushing for 300 rwh and will probably make it.
