2.4 to 3.8 swap

[joeyjoey]

for a smaller budget why not just build a good nitrous motor?keep it mild enough for a daily driver but strong enough for a big shot of spray for play time.

funny you say that, i was just looking at the thread with the kits for sale..

what would i need to do to set my motor up for that?

[titoares2004]

All I can think of is a cheaper way keep your tranny get a 4g63 turboed engine dohc of a 90-94 talon they were fwd and they do bolt right into our trannys and get all the parts you need for it then it'll be easier to build off of that motor and get a good ass after market hks turbo off road kit. (If your not going to use a daily driver) Or if you can see what you can do about getting an evo 9 engine. Theres someone i know selling the chassy of a corvette with an ls1 engine and tranny all you need to do is lay our body on it and mod whatever you need. Its just an idea I was thinking of since we're fwd which does make me nuts.

[eclipse628]

still looking for a 3.8 engine, tranny and everything else i need for a good price.. not easy..

[Freeker]

^ nope it isn't... now if you were looking for a 350 chevy with tranny... you could get those ANYWHERE!!! lol bought my LT1 for $500 bucks... beefed it up to a fully forged 383 and yea... got me some juice... those were gooooood times man... good times...

[Danester]

i have a 350 with tranny rusting out back.......

[Tsensational]

Just get a used Napier Deltic

[360jeepboy]

I bet that will shave some weight...

Find an eclipse gt 5sp auto that was rammed from behind and totalled. Part out its engine bay and use its electronic + engine + tranny to do the swap.

Here is why. I have a sneaky suspicion that the gs tranny and the gt engine wont hook up. and dropping one with a tranny hooked up to it allready would not only be easier but would provide you with another gear. Also we know that the gs cpu can run the Gt tb but that is as far as our swapping ability goes.

Now, I like the other guys wouldnt recommend doing this. I havent been on here much for awhile but Im pretty sure there are some great turbo kits for sale that will cost just a tad more than this swap.

Alright here we go all these guys are going to in depth and making this sound way harder than it actually would be.

1. The engine bay is already set up to take the 3.8l All you need is the hardware so no customization there.

2. Again the interior is already wired the wires just aren't connected to anything because its not there to connect to.

3. People keep saying custom exhaust blah blah. No you could do it two ways either get stock exhaust, Injen Header back, or Magnaflow Catback. Even if you didn't get one of those all you would need is to find a factory Y pipe and some flanges.

4. The hard part is going to be the ECU. You could do it a few ways Either run a stand alone in conjunction with your Stock ECU. Why in conjunction you ask simple CANbus. I assume you want to drive on the road. Well you will need all those little saftey devices, and commodities run by the CANbus.

(4B) Second way not sure how hard this would be to get, or how expensive it would cost. I don't even know if they would do it for you. But if you find the a 6G75 with ECU in tact Have Mitsubishi reflash that ECU to your car. If that could be done than you would be on Money street. Maybe even Hack might be able to do this you could always ask.

Cnofzz just a heads up to you and to all the other the 6G75 guys your sneaking suspicion is wrong. I now this from a trusted source who is working on a secret squirrel project on his GT with another 4g6x transmission.

heres an idea to drool over check out the vid YouTube - Civette Drift! http://www.youtube.com/watch?v=bfR_Z...eature=related

this guy thinking of diong the swap is a joke.
why not buy the gt in the first place for a couple of grand more.
you gonna spend so much time and money when you could of gotten a gt from the start.
if you really have a shop that you can use for the project, do internals then f/i. you will be faster than gt and be one of the few boosted gs.

i see where he is coming from... i dont think he is bs'n
no one wants to be upside down on a car loan. it isnt worth it.
he prolly assumed that jumping to a 3.8 would be a direct fit, with it being the same body and all.
or he couldve been like myself and wasnt afforded the choice of a gt.

[Danester]

so if you have 10 grand to dump into an engine....make a payment on the gs, and finance a GT......problem solved....i can't imagine you being more than 10k upside down unless you ran the car through a cheese grater...

[RJ88]

but im pretty sure he didnt think it would cost that much....

well at least i didnt think it would cost that much because i thought it was a direct swap... by the engine and trans and voila lol.. but im pretty sure yall can tell i be lost on some subjects.

i could of afforded the GT.. but i was dumb, rushed into getting a car and i didnt see a GT on the lot when i bought my GS

If he is going to do that then why doesn't he just pay off the GS, then go buy a car that is wayyy more bad ass then the GT. I.E. Corvette, Lotus, Evo, Sti, Supra, SVT mustang, hell even an older Viper can be bought for 25k now a days.

This is what I have decided to do. And if your wondering... the first two are my first choices

[RJ88]

im not saying u couldnt afford the gt (idk u or how much u make). i was saying u might not have been afforded the opportunity. (ie. u didnt see the gt on the lot)

[eclipse628]

yeah that was the issue.. the dealer has no GT's, not even a used one.. so i got the GS in a rush..

[leet]

lol they didnt have any gt's so you bought a gs
its like saying they didnt have any altimas 2.5 in gray.
so now you want to custom swap a gs with a gt engine.
go ahead buddy and tell me how much you spend to get 260hp

[Danester]

you would still spend less on an upside down trade in....unless of course you were bleeding out the ass when you bought the GS in the first place.....

[DarkSidEclipse]

Its still gonna cost a lot less than a lot of other engine swaps you see done.

[ryanastyG4]

Lol, stop being a qwiggity ^^

Dude just keep the GS for now. Im sure 80% of the GS owners have made a "Trade In" or "Crazy Swap" thread or post (myself included, a while back), but its because a slight moment of feeling inadequate. Out of this 80%, probably 10% go FI, the other 90% just learn to live with what they have until it finanically makes sense (paying the car off/getting more than what you owe).

Then you have the other 20% of the members who actually
do get rid of this boulder and move on to an actual GT, Evo, etc..lol

do you really need more horsepower (than a fill bolt on gs can attain) on the streets? So you can be like that one Florida tard trying to race all of miami in one youtube video, lol.

I am in no way bagging, I went through the same thing. Be happy you have a sexy that runs perfectly and that you are alive.

Do some bolt ons and make it really peppy for DD, then get suspension mods (sway bars, tower bars) and make DD even more fun by taking corners at 30 mph with no body roll.

These are just my suggestions.

This is assuming that you wont be tracking the car. If your intentions were to have a track beast, get another older car, so you can have it hanging up in the garage for months while you build, but still have a DD.

excellent post.speaks da truth.

[DarkSidEclipse]

If this post said LS1 swap or something that you would completely customize the subframe of your car people would be like go for it. However since you want to swap an engine that your subframe is already made to hold, and the inside is already wired for All the sudden its impossible, and would cost way to much. It will be much easier to drop the 6g75 in your frame than it is to put in an Avenger, or 3g. I see no reason if Micheal can reflash, and clone an ecu, why your keys couldn't be cloned to another ecu. Again you would have to talk to him as I don't know that for sure. I say go for it man just so you can look at the naysayer's and say hmmm well.

[Ballfade]

Like nasty said, best to enjoy what ya have and do bolt-ons etc.
My method of enjoyment is bolt-ons and nitrous, and I fuckin love it haha.
but shit, if ya want power that much, go for it!

[Tsensational]

Is this ever going to happen? or is it like the other noob engine swap threads?

[Danester]

it's just like the rest of the noob threads....it really is cheaper to trade it in and buy a GT, or a 370Z......or just about anything else....it's just not worth it in the long run

[eclipse628]

im not a noob first off.

second.. i would like it to happen.. i really looked into it, but i cant find a engine, tranny and the rest of the stuff i need to do it for a fair price.. i even tried to get good prices through the shop i work at and its still a very costly swap.. ill keep looking, but to be honest.. im starting to realize it may not be worth it.

[Danester]

didn't mean to call you a noob, i actually hate that....we were just saying it was just like noob threads....sorry to have made you think that....it was just a reference to the topic, not the poster.....in all fairness, I got lucky with getting my spare 3.8, i remodeled a bathroom for a guy that owns a junk yard, and he pulled one out of a wreck for me....all in all, I spent about 300.00 on it......keep looking, you may find one out there...and when i get done with my engine, heavens knows when that will happen, I will be selling the stock one i got from the junkyard.....

[trevroar]

I like facts, so I did some research... not because I was bored, but possibly because I may be doing this swap. So I'm going to push aside all of what been said about this and lay down what I've researched. ** this is by no means a how to swap motors, this is a brainstorm I threw together, and it is no where near a complete how to **

Power plant swap

Complete 4g75 Engine with engine harness
Transmission F6MBA-1-LKJA

To Mount

You will need

Engine Mount Stay Bar $3.85
Transaxle Mount $89.67
Steering gear and linkage protector $5.68

(Available on MitsubishiParts.com | "Mitsubishi Parts" at Less Than Dealer Wholesale)

This is all you need to mount the engine in the car, you can use all other mounts from the GS. Engine roll stoppers and center member are the same

To Cool

Radiator fans motors terminals are different, you may be able to alter the GS wire harness to work, or replace the GS fan motors from a GT. I’m not sure if the wiring is part of the engine harness or the chassis harness. Either way you will need to alter something to get them to work.

Radiators only need to be changed if you’re going to use an automatic transmission with the swap. Automatic 4g69 F4A4B transmissions aren’t liquid cooled as the GT F5A5A automatic transmission is. Manual transmissions are not liquid cooled.

To Move

If you’re going from auto to manual, you will need everything from the clutch pedal, through the master cylinder and out to the transmission. You will need to drill holes in the firewall to mount the pedal and master cyclinder. If you are going manual to manual, you need nothing.

Depends on what comes with your new engine, but best to upgrade these anyways.

Clutch
Flywheel
Pressure Plate

Everything from the clutch master cylinder to the clutch hose is the same.

To Go

Front Axles – you’re going to need them from the GT
These can be pricey, found MAC brand on ebay for around $70 per side

To Control

Traction control! My GS doesn’t have it, and I don’t know what will happen swapping in a GT ECU that may go looking for it.

To Ride

Rear suspension system is the same, but you will need upgraded struts for the front (Thanks Danester)

To Breathe

Unless your motor came with intake and exhaust, you’re going to need them, but why use stock.

Some things that are the same

Fuel delivery (pump & Injectors), Transmission Speed Sensor, Wheel Bearings, ABS Sensor, Camshaft position sensor, ignition coils, crankshaft position sensor

Some things that aren’t the same
O2 Sensors, starter, alternator, knock sensor

Other things

You can bring your ECU and keys to the dealership to get them programed. I'm not 100% sure how the gauge cluster will work with the swap, my thought is they will work no problems. From researching, my opinion is this could be an easy swap, and anyone who has swapped motors before could do this. If you can locate the parts for cheap, can be worth it.

First if you are lucky, a used motor is about $8000, trans axle about $6000. If you can find them cheaper, great!! But right there you are at $14,000 without buying supplies, tools, and other parts.

(EDIT) Found a motor from a 2007 GT for $1400, so the trans axle can't be much more.
http://cgi.ebay.com/ebaymotors/ws/eB...4235&viewitem=


I'm just betting you can find a good used GT at around $14,000, and save yourself a lot of work and trouble.

[Danester]

To Ride

The suspension system is the same.

This is incorrect, the struts are quite different, if you leave the 4g struts in and drop that larger motor on them, it'll drop it to the ground, the GT has a higher springrate strut made for more weight....

and you're right, that's a pretty "incomplete" list of brainstorming there......still cheaper to buy a new car......nice write up tho

I'm at $2450 for the motor and 6spd tranny delivered. If I can locate all parts and keep it under $4k and doing the work myself - I'm going to try it. Also, figuring selling what I have for the 4g69, including motor, I should be able to recover possibly up to $1500 of what I would spend on the swap. I already need to purchase a new transmission for my GS, so I'm already $700 into it anyways.

Thanks, I edited my post for your input

[Clovisman]

Well at least the older our car gets, the more used parts that are available and the cheaper the parts cost. I know two-years ago this would have cost you at least double, so good luck and keep us informed on your progress.

Not if you if the GS Sport like muah than they are exactly the same. The strut itself has a little thicker diameter and is a little stiffer

[trevroar]

Just bought the engine, $1245 47k miles, 150 miles from my house (complete engine, uncut engine harness, fuel system, intake/exhaust manifolds, tb). Going to pick it up Tuesday. Still shopping around for a transmission, seeing them between $800 -$1k with low miles.

Well it sounds like you're off to a good start!!

Please, when you get a little closer to starting the swap, start a new thread. I'm sure you'll come across some problems or maybe it'll be a straight install, but I'd hate to see it buried inside this thread.

Have you done an internet search yet? I did one yesterday and found some motors very easy. So if you contact those sellers you might find the transaxle just as easy. I believe the shipment for the motor was like $174.00, so the trans can't cost more then that.

Good Luck, this will be ground-breaking for all of us, and it will open new options for the community. Even if it cost a little more then just buying a GT, the information you gain will be invaluable to the rest of the 4G community!!

[trevroar]

Thanks Clovis, as far researching car parts, the best place to look hands down is Car-Part.com--Used Auto Parts Market

I'm currently creating a grocery list of items I'm positive I'm going to need, so I had already plan on posting a new thread to see what I can retrieve from other members. Before the motor is dropped in it will be getting new valve cover gaskets, head gasket, timing belt, tensioner and prolly a a hand full of other things... going to opt for new clutch and flywheel as well.

We'll see how it goes.....

the only thing that makes your GS a "sport" is you or some marketing gimmick from your local dealership, but if you feel the need to start making crap up to make your GS closer to a GT, that's ok by me....just know that there is no model of GS out there made by Mitsubishi that is a "sport" that has GT parts on it it's either a GS, or a GT. Period. now some dealerships sold an SE version, now these are still just a GS or a GT the SE stands for "stripped edition" and those were the ones that were stripped of all extra features and sold at a discount price to improve sales...if you have a "SE" then you have convinced yourself that it means "sport edition" when in fact it doesn't......sry...but your GS did not come with GT struts.....never happened
