3.8 6G75 Swap Discussion - Club3G Forum : Mitsubishi Eclipse 3G Forums

camoner · 08/21/2006, 10:24 AM

has anyone done any research into the 6g75 because i've found a 3.8l for not much more then then 6g74 at a scrap yard near me, if anyone has any info about what might go into the fit up id love to see it

From what I could tell when looking at the 4g, the mounts are in the same location that they are for us. The transmission on the 3G may not bolt up, but you could always get their 6-speed in that case.

If that motor is cheap enough, just buy it and try it out. If it doesnt work you could always sell it again.

EDIT: The ECU would probably need to be swapped too, in order for the MIVEC to work.

Dragon34x · 08/21/2006, 12:33 PM

actually, it be a very difficult swap. It is all electronically controlled. Meaning, even the throttle pedal shit is electronically controlled! You could probably use the block itself but using the rest might be a lil difficult. deck height is too tall for out engine compartment (nothing a lil after market hood cant handle, ie: raised hood) It would be very interesting to see though.

McLarenross · 08/21/2006, 12:50 PM

I recall Manybreaws saying that the bellhousings fro the 4G 6-speed and the 3G 5-speed were almost identical. Even so. Id just use the 6-speed. You would need the whole wireing harness and ECU though to make it work. Its easier to just get the 3.5 and bore it out to 3.8-3.9 and do some nice head work and drop it in.

Is there enough material to bore it out to 3.8L???

McLarenross · 08/21/2006, 03:35 PM

Russ is talking about 4.1 so i guess so.

4.1 strokers, not necessarily dependant upon bore but stroked out to 4.1

McLarenross · 08/21/2006, 05:53 PM

True. I forgot about crank travel. What do the wall thicknesses look like to you. Think .040"-.050" over is feasible??

Plenty of meat on the walls of all the Mitsu 6 cylidners I've come accross. It's the 4cylinders that you have to be careful about.

camoner · 08/22/2006, 02:03 PM

but think of wat you can do with a 3.8L if you bore it

, the thing is the electronics, do you think there would be a way to either keep something from my engine so I dont have to deal with it, or basically would i be driving a 4g in a 3g body?

I would talk to some of the guys at RPW about this. They seem to know the 6G7X platforms extremely well. I could be wrong, but I think they have setup standalone computers on Mivec engines. I don't see any reason why you couldn't do the same with some of their help.

TheFranchise · 08/23/2006, 11:34 AM

why not just use the 3.8L block and 3G heads or even 3.5L heads?

I am no transmission guru, but wouldn't you then need custom length axle's? The tranny may bolt up to the engine, but what about all the rotating stuff?

will they match up to the 3.8L block?

And correct me if I am wrong, but most of the 3.8's hp and tq gain over the 3.5 and the 3.0 is from the MIVEC technology right? I know you'd still get a gain from the displacement change, but you wouldn't be getting the whole shabang, so to speak. Right?

randyrat · 08/23/2006, 11:51 AM

Swapping the ecus and electronics should take care of the MIVEC technology issue.

While it will take care of the Mivec issue, someone stated earlier in this thread that alot of stuff on the 4G is electronically controlled. Specifically, the throttle pedal. If that is the case, I would assume that the gas pedal has some sort of sensor on it to see how far down the driver has pushed it. The sensor relays that information to the ECU, and the ECU then relays that information to some tiny motor attached to the throttle body that opens it up a certain percentage based on the input from the ECU.

I read an article a while ago about this "drive by wire" technology and how alot of car companies are starting to implement similar stuff. I am not sure if Mitsu did this or not, but someone Dragon34x seems to think so. Who knows?

Dragon34x · 08/23/2006, 02:03 PM

yup the 4g uses drive by wire shit.

injen00eclips · 10/03/2006, 09:58 PM

I own a 2006 G6 that uses a lot of drive-by-wire technology and happen to work at a pontiac dealership as well, it's some crazy looking shit to get involved with, so I'd be careful...but, where there's a will, there's a way and the you said the engine was cheap anyway.

camoner · 10/03/2006, 10:49 PM

cheap engine doesnt mean much, you know the formula time v. money

cyberbrain · 10/03/2006, 11:36 PM

the solution is pretty simple. and it can be done since the 4g has been out for a while now, you find a 4g that was totaled in a rear end accident. and some minor stuff in the front. buy the car and you now have a donor car. If I was going to do a MIVEC swap, thats is exactly what I would do.

Tearstone · 10/04/2006, 08:40 AM

Word on the street is that the 3.8L in the 4G has a non returnable fuel system. The 4G has a real uphill battle for forced induction.

Mike W. at RRE stated that you can't use an FMU on the 4G without building the return line to go back into the gas tank. Not that I'm an advocate of an FMU type system anyways but still. They used a lot more technologly on the 4G than they did with the 3G. Also the ECU is not the same either, the ECU Flash does not work on it.

why does that make it harder? who give a fawk about returned fuel?

Slippercream · 10/09/2006, 12:42 AM

I DO!

That explains how this car gulps so much fuel like it's free bottomless Mojitos on bitches' night!

So will running a return line back into the tank really be necessary? Ross and I were talking about just using the Ultimate for a simple solution anyway. Fuel return or not, the variances won't really matter that much if you're limiting fuel by injector pulse, I'd think.

Nah, not having a return fuel line does not really create any problems if you know how to properly setup a car for fuel

Slippercream · 10/09/2006, 01:01 AM

Fuel? What's that?

My Mr. Fusion runs on egg shells and beer cans!

dizzydragon · 11/08/2006, 12:58 PM

my mitsu tech says it "will not fit"
others are telling me otherwise

can anyone please offer advice?

thanks!

4g64tpsssst · 11/08/2006, 01:25 PM

anything fits just needs shitload of work just do it

McLarenross · 11/08/2006, 04:47 PM

The block will go in Im pretty sure. As for the exhaust manifolds.....No. The 4G rear manifold is worse that the 3G rear manifold.

Slippercream · 11/08/2006, 04:51 PM

You also will most likely encounter problems fitting that intake manifold in the engine bay. As it is, the 3G engine bay is much more cramped than that of the 4G. You may have to custom-fab one that won't come so close to the firewall.

ARACHNO · 11/08/2006, 05:20 PM

I wonder if this is indeed feasible, if the 3g will then suffer from the GODAWFUL torque steer the 4g has?

ByeZ28HiGTS · 02/25/2007, 06:07 PM

Where did He say that this was a 3.8L MIVEC engine? Mitsu makes a 215 HP 3.8 liter engine in the motero. I'm pretty sure that that is a 6G75, and that it shouldn't be any harder to put into the eclipe then the 6g74.

Really? Is this a Montero/Pajero outside of the US?

ByeZ28HiGTS · 02/25/2007, 06:24 PM

the 2005 and later Montero switched to a 3.8 liter engine.

http://media.mitsubishicars.com/deta...60619&mime=ASC

ByeZ28HiGTS · 02/25/2007, 06:26 PM

the hp gain isn't all that much, but 50 extra pound feet of torque would be nice. If I had to guess I would say that fitting the exhaust manifolds into the 3g would be a bitch. There's barely enough room for the crappy rear exhaust manifolds that the car comes with.

ByeZ28HiGTS · 02/25/2007, 06:36 PM

I guess it runs on regular gas too? Nice, It'd be nice to see what this motor could do with headers, an intake, and tuning for premium gasoline.

Right. . . it'd be nice to have the info for both too.

At the risk of being really flamed if it has been posted already, I put this up on the other site and I'd like to hear what y'all think.

Have any of you considered putting the AWD sporty transmission from the magna on the 'clipse? It bolts up to the 6G74.

I did a quick search and didn't see anything about it. If it's a dead horse, go ahead and flame me.

Dragon34x · 03/07/2007, 04:27 PM

I didnt find anything. . .

anyone here got the info?

citm2000 · 03/07/2007, 04:43 PM

With people spending thousands on mods, I have to think that someone is crazy enough to spend the money to import that tranny.

Dragon34x · 03/07/2007, 09:34 PM

oh, i was talking about the injectos . . . .

Sleepr03GT · 03/07/2007, 10:16 PM

i'd really enjoy someone giving this a try for the rest of us, because a guy down here ran 13.8 bone stock on an 4g GT

i'm wanting to see what it will do in a smaller chassis

ahspimp023 · 03/07/2007, 10:23 PM

Would love to see this dream come true, it could be a one-of-a-kind.

Dragon34x · 03/10/2007, 09:42 AM

Anyone with info on the INJECTORS!!! . . . need to know asap, cuz i got a pretty good chance to buy some for cheap if they are around the size that i will need!

Maxpow99 · 07/30/2007, 01:41 AM

These engines are getting cheaper... Someone needs to get the dimensions and compare them to the 6G72 Dimensions so we have an idea of fitting in the engine bay. I'm looking at swaps simply because displacement is key if these cars are ever going to be up there speed wise.

Devin01RT · 07/30/2007, 02:09 PM

It's already been proven that it will fit, but very tightly.

Maxpow99 · 07/31/2007, 04:14 PM

So the axles with line up? If not couldn't you always use the 4g axles and Diff and just swap that in too when you put in the engine??

onewkd3g · 08/01/2007, 04:25 PM

I have a question, if 3.8 uses the drive by wire setup couldnt you just swap the throttle body off the 3.0 and put it on the 3.8? wouldnt that get rid of that particular issue, and then just use the ecu off the gts for the mivec control?

Devin01RT · 08/08/2007, 12:50 PM

I'm guessing you'd have to keep the 3.8 ECU for it's own motor...

onewkd3g · 08/09/2007, 08:14 PM

I kind of figured that, but would there be anyway to get around the drive by wire set-up, thats the only reason i posted that question. that shit is a pain in the ass to work with.

PhantomGTS · 10/29/2007, 05:12 AM

Sorry for asking a reoccuring question, but I really need a quick answer. Will the 3.8L fit in the engine bay or not. Heres why I ask. I came a across a 6G75 from a 2006 GT Spyder that was given to a fire dept. by me. Well they cut the car up, and the engine, transmission, and rest of the chopped up mess resides in a junkyard. The owner is selling it for really cheap I guess, and I want to know what all I would have to do to get it in, and running.

Devin01RT · 10/29/2007, 01:13 PM

If you would've read from above the engine mounts "appear" to be in the same location, it's just not certain that the transmission will bolt-up directly. You'd also need the ECU and anything else that is electronically controlled. I'd say stick with the 3.5l swap.

As for the exhaust manifolds.....No. The 4G rear manifold is worse that the 3G rear manifold. __________________ Gig'em Aggies!!!

As it is, the 3G engine bay is much more cramped than that of the 4G. You may have to custom-fab one that won't come so close to the firewall. __________________ "You want to see turbines on my 4G, go ask Shihab to give you one!" - Slippercream "Yeah, he's got a Miata with MazdaSpeed rims and a MazdaSpeed front, you'd think he'd have a turbine, coming from the Land of Turbans!" - McLarenRoss __________________ mySpace \| Club3G on mySpace CPA in 7 months !!!

ByeZ28HiGTS Senior Member Join Date: Jun 2005 Posts: 231	the hp gain isn't all that much, but 50 extra pound feet of torque would be nice. If I had to guess I would say that fitting the exhaust manifolds into the 3g would be a bitch. There's barely enough room for the crappy rear exhaust manifolds that the car comes with.

Have any of you considered putting the AWD sporty transmission from the magna on the 'clipse? It bolts up to the 6G74. I did a quick search and didn't see anything about it. If it's a dead horse, go ahead and flame me. __________________ Who is John Galt? Mein Gasfuß der wird mächtig schwer.

Someone needs to get the dimensions and compare them to the 6G72 Dimensions so we have an idea of fitting in the engine bay. I'm looking at swaps simply because displacement is key if these cars are ever going to be up there speed wise. __________________ 2k1 Eclipse Spyder GT
