V6 into DSMs [merged 12-17-06]

My buddy thought about getting the swap done on his avenger but I guess the guy that does the swap charges like 6k to do it. Not sure if that includes the motor tranny etc.

If you were to want more performance out of your 2.5 I'd homebrew turbocharge it or buy one from the vendors who make them for them. They make superchargers for them also.

There was at one time a guy selling custom manifolds do you can bolt on a 3.8l supercharger off a gm. After looking at clearance issues though we decided not to do it. We still have a new 3.8 charger sitting at home.
 
Ok I am a newbie here and from the sound of it this topic has been cover time and time again, but I am considering this swap and would like to have as much info as I possibly can get before I commit to doing this.
In my search for info on this swap I have seen posts that say that you would have to swap in the Trans from the Avenger too because our transmission won't work with the V6. But right now on ebay the 41TE A604 tranny is listed as being for both the Eclipe/Talon 420a and the Avenger 2.5 V6?? Is this correct?? Just would like some clarification on this.

Not at all. This is where it gets into us suggesting you abandon ideas of this sort of thing and stick to the tried and true methods of making a DSM fast - big turbo. My advice to you, and this is with no sarcasm, animosity, or otherwise shit-talking attitude, is to build and boost what you've got now. When you know what you're doing with this chassis, specifically, you will be in a better position to consider something like this.
 
Just turbo your v6. They can throw down some decent power too. I'm helping my friend with his 3.0 out of his newer sebring which is basically the same. We made up all the pipes and used external wastegate. He got a to4e for some reason off of ebay. It's not the turbo I would have chosen for flow reasons, but it seems to be working pretty well. We are just boosting 8psi on it and it pulls like crazy.

I've heard that these v6's also have forged cranks and rods, but have cast pistons. I know rip mods makes kits for them and is putting down 400's I believe.
 
I was just wondering how many people had tried this process, and what was involved. How about a little more help and less this "it can't be done, just turbo your 420" If this is the kind of crap you guys have to say why not just tell me to sell my N/A and get a Turbo, cause thats just about all I've heard.:beatentodeath:
 
The first generation Dodge Avenger was a 2-door coupe produced from 1995 to 2000, replacing the Dodge Daytona and the Mitsubishi-based Dodge Stealth (which was discontinued in 1996). The Avenger, along with the similar Chrysler Sebring coupe, were built by Diamond Star Motors (DSM), a joint venture between Chrysler Corporation and Mitsubishi Motors, on the Mitsubishi Galant (FJDS22) platform. This joint venture between the two ended in 1995. Avengers and Sebring coupes built from 1995 to 1996 both have DSM markings in their engine compartments.

The Avenger had a 103 in (2.62 m) wheelbase and used either a 2.0 L I4 (the Chrysler 420A) or a Mitsubishi-designed 2.5 L V6.The 4-cylinder was coupled to either a five-speed manual transmission, shared with the Mitsubishi Eclipse and Eagle Talon, or a 4-speed automatic. The V6 was only available with the A604 transmission, and cannot be swapped out easily due to a lack of transmissions that can fit around the front axle. The easiest way to swap out the automatic transmission on this car is an entire drivetrain swap.

The second generation Mitsubishi Eclipse (95-99) was basically a "shorter" version of the Avenger, and at least 80% of the parts can be used on either vehicle. The main exeptions are the windows, exterior lighting, hood, trunklid, and bumpers. One could swap an Avenger front end to an Eclipse and vice-versa, by swapping the fenders, hood, upper and lower radiator supports, and so on. Some drivetrain components are universal, as are with most interior, and almost all the suspension components.
I see this on alot of boards. Most people instead of swapping engines just change out parts to make it look like they have an eclipse instead of an avenger and vice versa. There seems to be alot of custom fabrication involved.

so are there any parts off the avenger that would be considered an upgrade on a 2g gst?

The point is, you'd have just as much luck asking us how to rebuild a Pratt and Whitney PW800 Turbofan jet engine. We can speculate, but only a small handful of people have had experience in actually doing it. As such, the routine goes like this:

New person asks how to swap engine X into their NT.
Out of the 60,000 DSM owners registered between here and 2GNT, perhaps six of them have either tried or completed it.
If we ignore the thread, new person gets pissed that we aren't being "helpful."
If we suggest an alternate course of action due to limited information being available, new person gets pissed that we aren't being "helpful."

Perhaps that's all you've heard because you haven't been listening.

I've not said it's impossible. I've not said it's got no merit. I've just stated that there is little to no information or desire within the community for this project so the only way to get any real help is to get knee deep in that shit and then come to us with specifics that pertain to those aspects of the chassis we know about.

We've already covered that, in order to use the 2.5L engine from the Avenger, you'd have to swap over the automatic transmission to make it work. - Who wants an automatic? :notgood:

Then we've stated that it's only got a marginal increase in power over your 420A. - The power gained is not worth the resources required to obtain it. :notgood:

Then we've stated that, should someone get into the swap and ask specific questions, rather than, "Hey, how do I do this?" We'd be more than happy to offer help and ideas.

You act as though we're holding out on you. We are not. We know about building and turbocharging the engine already in your car. We know that, compared to ANY swap, it is CHEAPER and EASIER to make powerful. That's why you're not getting detailed information about how to do it. The DSM community, as a whole, isn't interested in doing the swap. It's only marginally more popular than putting a 2G body on a lifted 4WD Chevy S10 frame. (Which has also been done.)

Sorry to let you down, man. That's just the way it is. :beatentodeath:
 
So... are we done with this thread yet?

I'll give it another two to three posts before it's closed...
 
:dsm: yes, this thread is done. And for all who called me a "newbie" I have been on here for nearly 3 years, I just haven't done as much posting as i have reading. Sorry for all the problems this caused thank you all for the information you provided.
 
Sorry for causing any problems, was just wondering if anyone in the community had done this swap.

Thanks for the pic showing that it can be done.
 
I bougt a 97 eclipse gs 2.0n/t auto with a bad engine, and a 97 2.5L v6 sebring with no title. And i am almost 100% sure that everything should be able to go into the eclipse from the sebring. Since they are both based on the same chasis, i dont see why the v6 engine and trans + full wiring wont completly bolt into the eclipse with a little wiring of various things.

However, i have never seen anyone do this...

I have a 1jz swapped supra, but its an 87 so its not real flashy (not exactly what i want to get dates in) So i want to get the eclipse going for that sort of daily driving but i hate the 420a like you have no idea, The sebring has plenty of power and tq, plus its decent on gas.

Some tech info would be great.
 
There was a picture and thread about someone doing this but they swore to never do it again because the gains were not worth it and it required a bit of fabricating.

Dude, you're going to need ALOT more then 'little wiring'...
If you're a master fabricator go for it.

BTW, there's a reason you cannot find any information or people who have done this.

Also, I don't think the 420a likes you much either.
 
The engine bay is slightly smaller in the eclipse. The guys and myself at Exile racing did some measuring and if you look closely at the core support of the avenger, you can see where the additional room is added. It will take a lot of work and when your done the gain wont be that great.

To add to the frustration, you are converting from a Chrysler platform to a Mistubishi so interfacing the chassis and engine harness.
 
I would like to add to this thread that as to date, there are currently 4 awd 4g63-t avengers running around. also, the grey one posted earlier in this thread has since been parted out and most of it sits in a junkyard. not that it ran bad or anything, he just wanted a new project. there is also at least 1 more 4g63-t awd swap in the works right now.

also, for those contemplating the 2.5 swap, consider using the 3.0 from the 01+ strats/eclipse/galants. its a 200hp engine that has the same external size as the 2.5. its a very common swap for avengers. pretty much drops right in.

just something to think about ;)
 
You are way too narrow with your idea. What kind of V6 motor are you planning to use?
Also, almost anything is possible, it just comes down to how much money you want to spend, and will it be worth it? Usually with motor swaps this complicated, no.
 
yea you could put anything in it. Hey throw a v8 in there.

but seriously it would cost you 15-20K. Turbos are usually the way to go with eclipses.:thumb:
