Please, if you are asking for help with diagnostics, do everyone a favor and list the make, model, year, trans type, engine type, modifications, etc of your car when asking questions about it. Most of us aren't mind readers (although some of us may play one on tv). It will help you get the help you need faster and keep me from asking so many questions and increasing my post count unnecessarily. I think we need a standard format for questions.

year:
make:
model:
mileage:
trans type:
recent maintenance:
recent modifications:
other modifications:

Something like that will help everyone out that is trying to help you. So, please take the time when writing your post to include this much needed information. All of your friends might know what you drive... but we're not your friends

Where can I get OEM parts at wholesale pricing?

What are some good sites to find parts?

My Radio Displays ERR or ofF

My Sport Tour light is flashing. Why?

How do I change my fuel pump?

My "Brake" light stays on, even after the E-Brake is disengaged. Why?

The main reason to go turbo is the added power. I am going to do a short write up of the process of the easiest way to Turbocharge a non turbo 3000GT or Stealth.

I wouldn't even think about taking one piece off of your car unless you have all the parts, or you have a second reliable vehicle.

The first thing I did was put the car on four jack stands and take the two front wheels off. Once the car is up off the ground you will find it 100% easier to work on as you don't have to bend down into the engine bay, and getting underneath is pretty easy. Granted a lift would be 200% better I dealt with what I was given.

So the car is up in the air. THIS IS IMPORTANT! If your seats are power, move them all the way back as the next step is to remove the battery. Put the battery in a safe place and not on a concrete floor.

I would then swap the fuel pump. You have a couple options here.
1) Use the TT stock assembly and pump and its a direct drop in.
2) Use the TT stock assembly and an aftermarket pump.
3) Use the NA stock assembly with the Stock TT pump or aftermarket pump. (this will require some modification and the use of worm clamps or hose clamps)

Once the fuel pump is in you can close the trunk as that the last time you need to go in there.

I then sprayed down all the nuts and bolts on the exhaust with PB BLASTER, (don't waste your time with anything else just shut your mouth and use PB Blaster) Spray the headers, the down pipe and the cat bolts.

Now while thats doing its job, you get to get organized. I bought Number tags and used them to mark everything I disconnected. This is where I disconnect all the wires on the transmission side of the engine. Connections start at the throttle body and move towards the front bumper. Remove them all. If It is a wire and hooks up the engine disconnect it and mark it.

Drain the radiator, oil pan, oil filter and transmission.

Remove the cooling fans and radiator and store in a safe place. BE SURE TO GET ALL THE FLUID OUT.

Remove the Waterneck and thermostat assembly. Be sure to remove the corrosion if you are using used parts.

Move underneith the car and remove the Driver side axle. This will make your life easier with the rear header and rear motor mount.

Now remove the Downpipe, and as much of the exhaust as you are changing.

Swap oil pans.

Remove front manifolds.

Swap the front motor mount bracket.

Remove the AC compressor and bracket to gain access to the oil filter housing. Swap these. Reattach AC bracket and compressor. You are not actually removing the compressor, you are only unbolting it from its place and moving it away so you can work there.

Clean your hands.

Take the front bumper off.

Stuff the holes on the intercoolers with rags.

Install the passenger intercooler.

Now the fun par find a dremel and go to town on the driver side. first mock up the driver intercooler and see where the hole needs to be and then open it up. Attatch the driver intercooler. The holes are in place so just use the existing holes. The passenger side is easier because the intercooler is the only thing on that side. The driver side also has the oil cooler.Which you should also hook up at this time.

If your oil cooler is not new, you need to flush it. Go to a coin op with a can of PB blaster and flush the thing. Make sure the water is CLEAN when it comes out and make sure you get it all out. I used a heat gun for a couple minutes before I decided it was dry on the inside.

Now with both intercoolers hooked up and the oil cooler attatched the frame take the hoses and attatch the oil cooler to the Oil filter housing. Use NEW crush washers.

Assemble the front turbo. Oil lines and cooling lines. Attach to the front manifold. Then take the whole object (manifold & turbo & O2 Housing) to the front of the block. Attach cooling lines and oil lines.

Keep the rear turbo handy. Remove the upper intake manifold (Plenum) Stuff rags in holes left on engine IMMEDIATLY.


YOU ARE FUCKED IF A BOLT FALLS IN ONE OF THESE HOLES


Remove rear manifold. Swap with Turbo manifold. Attach rear turbo. To the manifold. Attach all lines. Attach rear O2 housing.

Remove the Fuel rails. Swap the injectors. Solider the resistors into the front and rear harness. Reattach the fuel rails with the larger injectors.

Replace the fuel rails.

Put on the Turbo upper plenum. The reason I reccomend using the Turbo plenum instead of the NA is the NA has the VICS motor exactly where the rear turbos hard intercooler pipe wants to go.


Now both turbos are on the engine. Hooked to an oil source and water source which also means that the water neck is changed and that the oil filter housing is changed. You also should have the oil return lines hooked up the the oil pan. This was a pain in the ass and I reccomend getting longer bolts to do this. This actually took me close to two hours pretty much the hardest part of the whole thing.

Attatch the intercooler pipes and hoses to the turbos and intercoolers.

Reattach the exhaust. You should have an 02 sensor and a wide band sensor installed in the exhaust before you bolt it up.

Now its time for the gauges. Wire those in. I reccomend, a wideband, EGT (placed in the rear exhaust manifold before the turbo, and a boost gauge.

Also install the SAFC.

Pull your plugs crank the engine to prime those turbos. Put the plugs back on start and hope you are good.

Everything You Need to Know About the Car.

This is broken up into a couple sections. Modifying, History, Common issues, The Active Suspension, Search

Modifying:
The vast majority of people who buy a 3000GT non turbo are under the impression that one day they will do the twin turbo conversion. The sad reality is that 99% of them will not. Of those 99% about half will have their car blow up. The rest will sell and buy a turbo 3000GT. Another misconception is that BPU upgrades on the non turbo models actually do something. Nothing noticeable will happen. There are no chips or programmers available. Buy your self a set of cams and cam gears. Taking the rear seats out of this car will not make it any faster, sorry not going to happen. It is not a race car it is a Grand Touring Car.
If you bought an automatic… enough said.

If you have a turbo car the first upgrades should be intake, downpipe, cat back exhaust, boost controller and boost gauge. From there you will need to decide what you actually want to do and how much power you want to make. That is a topic in it self.
If you have a non-turbo, you can do intake, headers, cat-back, (not going to net much real world wheel gains)

History:
The Mitsubishi 3000GT
The Mitsubishi GTO
The Dodge Stealth
Guess what, with the exception of a couple body panels and the GTO being Right hand drive no difference. They did have different submodels but they are the same car.
GTO stands for Gran Turismo Omogolato which is translated from Italian as a grand touring race. The reason it was named the 3000GT for stateside use was because Mitsubishi did not want to confuse buyers with other cars such as the Pontiac GTO and the Ferrari GTO. 3000 GT stands for 3 Liter Grand Tourer. Dodge Stealth, Dodge has always had nifty names.

Common Issues, questions, concerns, things that people need to know and ask with out searching:
1. The gauges are just estimates they are not actual readings. EXPECALLY the boost gauge, do not use the stock boost gauge to judge boost.
2. Yes, you have to take the entire intake plenum off to change all six plugs, no changing the front three is not good enough, no its not hard to get to the last three.
3. Changing this car from any configuration to rear wheel drive is useless, go by a Z
4. The GENERAL consensus is that body kits do not look good on the 3000GT, Maybe a front lip and some new rims but dump your money into the motor.
5. Anyone who thinks a non turbo 3000GT is fast or quick, is sadly mistaken.
6. You only need one blow off valve.

The Active Suspension:
That little annoying green flashing light on your dash that says tour/sport is for your active suspension. If it’s blinking the system has broke and defaulted to the Sport mode. If you want to attempt to fix it you can check the four connections which are on top of each strut, than I would check the computer and by check I mean replace, or if you don’t mind it always being in sport mode just disconnect the computer and that will turn off the tour sport light. Looking in the trunk to the right there is a plastic panel with one screw, remove it and unclip the two plugs.
As with any car if you lower your car you need to get matching struts. Some people will argue that you don’t need to if you only drop an inch, but I don’t see why you would not do the complete job correctly the first time.

Search:
When using the search feature only type key words such as, “PWR ECO” for what does the PWR ECO button do? Or, “Tour Sport” for what does the Tour Sport light mean?

Remember to do your timing belt and water pump every 60,000 miles.

Also, keep in mind as with any other car,

Cheap, Fast, Reliable.

Take a look at the list, now pick two because that’s all you are able to have. (Which ever two you pick are the ones your car will be, the other one is what the car will not be.)

TEAM3S.com has a complete walk through for just about anything concerning this car.

And as a friendly reminder, please use the search feature.

ok guys i have been dealing with this problem for some time now... every time i go out to start my car it cranks for ever until it starts and this is not usually a case for fuel injected cars... if i crank it short spurts like say 2 seconds then let off the key i hear a click from the mfi relay.. after repeating this process 3 times the car will always start right up!!

kinda stubles from time to time like is thirsty and not getting enough fuel then after a couple seconds it smooths out like normal then im good to go to my next destination... if i shut the car off and attempt to restart it within a couple of mins then it will start right up but if i let it sit any longer then its alot of cranking again which gets rather annoying..

i had my mechanic test the fuel pressure he told me that on start up it has low fuel pressure and at idle it is 10 lbs lower than what it should be and that when i shut the car off the pressure is bleeding out of the fuel system when it should not be..

it seems to me that after i replaced the sending unit, i started having the hard starting problems...the sending unit i put in the car was a used one from the junk yard and was a lil rusty looking but far better than my original one which developed a hole in the high pressure line right above the fuel tank.. with the sending unit from the junk yard they also gave me a used pump which i did not use do to the fact that i knew that my original one worked fine so so far im using the sending unit from the junk yard along with my original fuel pump

just a quick list of what i have done to this car so far include
a brand new fuel filter
ptu
spark plugs and wires
new air filter
new iac motor
2 different ecu's
new fuel pump strainer sock filter
different fuel sending unit(used)

on a side note i did cut the catalytic converter out and i did away with the entire evap emissions system so there is no emission devices on this vehicle and this model did not have an egr valve... the exact model is a 92 3000 gt sl with 143000 miles on it...does any boday have any ideas?

I was wondering if any one can tell me if the 16x8 wheels from a base model 97-99 3000gt will fit over the 4 piston calipers from a tt model?

thanks.

recently bought an imported gto twin turbo mr. was wondering how i can find if and what had been done to the car tuning wise before i decide what to do next
any help would be much appriceated

Is on Ebay.

http://cgi.ebay.com/ebaymotors/ws/eBayISAP...X:IT#vi-content

I have a 91' 3000 GT SL that is my baby. It has come to a point where I need to ethier buy a new car or fix up the one I have (have 216,000 miles). Also, I just lost my mechanic. Personally, I would like to replace/upgrade the engine (maybe to turbo), put on a new suspension, repaint the shell and redo the interior. I was hoping someone in this forum could help me find a place they trust to do this kind of work in my area who is not going to gouge me. Any suggustions are appreciated on where to go and what I should do to the car.

hey guys new here. I was wondeing if it better to buy band new evo or go for something a little bit older. As I do want to impove the car when I do get it.

Hi, I need your help... How do I remove the speed limiter on a 1992/1993 6G72 Twin Turbo GTO? Its limited to 180km/h.

Ok, so I've been in the market for a little bit of a 3000gt vr4. I finally have the money and found one that seems to be in good condition. He was asking like 5,300, but I offered 5000 and he took. It has a 137k miles, which is a lot, but it's a 1993 so it's been driven pretty sensible. The thing I like most about it is that it's 1 owner. So I'm definitely more inclined to buy it because for the same person owning it for all those years, it must have been a pretty reliable car. I am in the midst of finding out if the timing belt and water pump have been replaced every 60k miles, and he said that the thing shifts very smoothly and there's no engine faults or anything. I'm just wondering what you guys think. As far as pictures, here's the ebay link :

http://cgi.ebay.com/ebaymotors/ws/eBayISAP...p;category=6350

And then he also posted up a video on youtube :

http://www.youtube.com/watch?v=vmuhenz8BBk

I think for the year and mileage the cars seems to be in good condition. Obviously the interior has some faults, like the shift boot, worn seats, sagging leather on the passenger door, but those are things I would expect. So once again, just let me know what you guys think. Thanks for your time guys!

I have a JDM GTO, a few weeks ago it started heating up, I've recently had the timing belt changed along with a compression test, and NO HEAD GASKET problems. oil looks good, dirty but good, coolant was green ad coolantish... there are no leaks of coolant, and nothing major in terms of the oil leaking out. Thermostat has been replaced.

The car starts OK, and runs fine for a while and then starts to heat up while driving say on the highway at 3k RPM. I can coast (push in the clutch for a bit) it will cool back down...
I've run a radiator flush last weekend however the car still has the issue...


any ideas...

Pardon my ignorance, i'm looking to buy a GTO, but have'nt yet seen a 3000GT. So whats the difference ? Is one better than the other or is it down to personal taste ?

I have a 91 gto. Its a beautiful car, only one thing lets it down,its a clutch problem it has always had. Sometimes it works fine, other times its a real pain. You push the pedal down and you get half the way to the floor of free play and when you do get pressure its really stiff and hard to push down and you can only just change gear. I have tried to fix it over the years but to no avail. I have replaced the clutch and pressure plate, replaced the master and slave cly. Even put a new hyd line in. I am about to replace the booster as a last resort. But im not holding my breath. I have been to many mechanics and all have been left scratching their heads. If after I get the booster done and it still plays up, What is there left to fix.

would a GTO right side headlight motor from the UK be able to fit into the US 3000gt? i kno it might be a silly question i just want to make sure..since the right side motor on mine is burnt out i need to get a new one

just wondering when someone will post a guide to upgrades on the 3000gt/GTO's or if they have why it hasnt been stickied yet

Hello.. I was just wondering if anyone knew how or knew a site that tells you how to replace a Brake Booster and Master Cylinder...

(My car - 1992 Dodge Stealth R/T)

i need an obd2 vr4 to help with my diagnostics on my car. highly modified etc etc, im in the navy and will be coming home on leave shortly, and need to have it fixed and registered in 10 days max. i will compensate you for your time.

Just bought a 1991 gto mitsubishi but the clutch is completely gone. Wanted to know if a 3000gt left hand drive clutch would fit a gto right hand drive? Thank you!

well last week the car started to jerk n shake at stops and then i could not get it into gear on my way to work one morning, there went the act stage two sprung 6 puck and flywheel. now i just put a brand new oem clutch and flywheel in myself with my dads help, first gear was gone after we got everything back together, ok i could deal with that. but i had to make a trip to school and back its a hilly trip to and from school, then i started to notice that the car would start to barely move, but i was only a 1/2 mile from my house so i tried to get it home about another 1/4 mile i noticed that the clutch was starting to roast so i stopped immediately. i have only had this car since april and was wondering does the transmission need a rebuild or do i need to get another transmission from a junkyard? also i was on craigslist and there is a guy selling internals from a awd model, can these work for fwd?

thanks for any help, tank.

hey guys i live in ireland and was wondering does anyone know where i could get a full leather interior for my car ???

Does anyone know of a good shop in Atlanta, GA to do a engine rebuild on my 1993 3000GT VR4? I found a place in North Carolina (3SX Performance), but they are a bit pricey. I was trying to find a place in Ga that was a little cheaper than what they quoted me. If anyone has any recommendations, holla back at me!

i have an 03 eclipse gts with the 3.0 v6 and i have heard that the pistons are really weak. so what i was thinking, is it possible to put 3000gt pistons into my eclipse. what mods would i have to make and would it even be worth it. thanks

I just hit the 200,000 mile mark on the way home. zooooooooommmm...

I think it's time for a timing belt.

hello everybody my car is a 92 3000 gt non turbo and my question is concerning the car stereo system... i want to hook up an after market radio up but when i pulled out the factory radio i was amused by all the wires going to it that i was not expecting... there is no harness adapters that i can find any where around here so im going to have to hard wire it in... does any body have any advice or any wiring diagrams to help me along the way?? i have no idea what each wire does

newm GTO owner, got as car last week, 1992 GTO import non turbo V6, the dash warning light between the SRS light and the seat belt warning light comes on when cornering, something is Low,
is this coolant as it seems full??
thanks

Im wondering if someone has some advice for me on my GTO
Its a non turbo 1993 L reg, facelift, automatic , today the car over heated on me and it still had water in the tank, i was thinking it was the thermostat?
or their is a hole in the radiator ? but if it was a hole wouldnt i lose all the water, is it possible that their is a block in the water line? as the car has been off the road for 5months and the tank is full of gunky water and looks as if it has never been bled
I defo dont think the water is getting to the radiator as the pipes to the rad seem to have no water swishing in them, i think they are dry
thanks in advance
cheers!

This forum is weak.....anybody know of any geared more towards 3000GT and not girly eclipses and lancers? Thanks

Can i bleeding my clutch from under the car?

need help timing a 1997 3000gt sohc a diagram would be a lot of help never worked on one before not my car

Good evening all. I picked up my 1992 Mitsubishi 3000 GT SL 4 months ago. Everything is factory Original with only 57,000 miles on it. My question is I live in South East Michigan and I'm looking for performance shops that others might deal with in my area. I'm looking to beef my engine up just a little without swapping it out considering it has nothing wrong with it. Guess I'm looking for budget performance tips. This is not the VR4 and I'm not very knowledgeable in Imports. Most of my other cars have been Trans-am's, Firebird's, Camaros, and Corvettes .

Thanks for any constructive input.

Hey im looking for red touch up paint(paint code R71) for my 3000GT, and was wondering if anyone had any advice on where i could find some for cheap. I've check all the local autozones and o'reilly's and none of them seem to carry it. I even called the paint shop where my front bumper was repainted a week prior to me buying the car and they didnt have any left over! So if anybody knows of where i can find some that would be great. Thanks

Hi all,
my 1992 gto tt wont start, and doing a check with a spark plug i found it to have no cranking spark......
now i know it could be many things, from coil, to ecu, but i would like to eliminate the cheaper things first .
whilst it does have an alarm (toad ai606) which has an immoberlizer, i am sure this only cuts out starter motor, unless it has 2 circuits ?
but looking at the tis cd, i noticed that gtos come with a factory fitted immoberlizer relay which is located on the passenger side of the center consol. i have checked my car and it does have some sort of relay, can anyone conferm this, and can it be checked.

i have just bought and waiting delivery of a obd1 data logger/palm computer with diagnostic programme. from ebay.

is this a common problem with gtos, i just seem to have one problem after another.
any help would be greatly received.

Hi guys
Does anyone know what the red light on the dash cluster that has a symbol like an exhaust with 3 wavey lines coming from it means??
DDD

Looking at a pristine (exterior) 94 3000GT, Interior driver seat has the typical bolster issue.

Anyway, question is, upon starting, and when you initially goose the gas, a small amount of white smoke comes from the exhaust.

Failing head gasket? Didn't see any evidence in the oil.

Rings? if so, any ideas on cost to repair?

recently purchased 94 stealth it has reverse,thats it fluid is BAKED stinks to the max i am sure it is cooked

found a 95 stealth w/good trans will it work?

books say 94 1 year only

trans rebuild sites say all stealth 91-97 same part #

can anyone tell me if this 95 trans will work?

thanks

hi all i have a 1991 gto auto
when it starts from cold it runs for a few minutes then misfires and then stalls

the last owner has replaced the whole exhaust system for a big bore type(make unknown) and a k&n style air filter
have cleaned the iac(idle air control motor) removed then refitted the battery and its made no difference now the check engine light has come on just before it stalls however i have not read the code yet
the iat/airflow meter has been bonded to the air filter so i cant remove it to clean it out

the problem has gradually gotten worse and with none of these prestigous cars in any of the scrap yards its a bit of a pain to swap parts about

any help would be most appreciated

many thanks

madandy

ok so when i got my 3000gt the guy said it needed a tune up and he was deffinitly right..the thing was firing on like..2 cylinders. so i fixed the plugs and wires but its still idling in like the 300's and when i stop the car and downshift the car dies on me..just wondering what u guys think is wrong? the plugs and wires are new so its not that..im thinking either the ECU or maybe the coils any info would be great

Hey people

Everything is working well on my car, except one thing now!!

When i was testing a faulty radiator fan, i done the connect to battery and connect to the 2 middle terminals on the fan itself jobby.

Stupidly i also tested it on the other end of the cable which goes somewhere else (RELAYS???).

Whats happens now is 2 things.

Firstly the Aircon fan is always on now. Not on low speed but high! (originally it was on low speed with ignition until air con turned on_

Also the radiator fan is now on as soon as you turn the engine ignition on, and goes off as soon as you turn it off... (basically always on with engine !!!)

It doesnt only come on to cool down now

Any ideas what we have damaged? and how to replace it. The relays and fuses all appear to be fine. but obviously relays are a bit hard to work out!

Hellllppp

Thanks again

I have a 3.0L 1992 Non Turbo GTO !

There might be handy pictures to somone trying to understand where the timing marks are. The marks behind the crank pulley are particularly tough to locate on the first go-around:

Hi,

bought my first GTO on friday but had some major overheating problems on it.

Its a 3.0l non turbo 1992.

It appears the radiator fan isnt kicking in. And as such i have cracked the water pump.

Ordered a new radiator fan and water pump for £100 which are getting delivered tomorrow.

On testing everything it appears i have also done something to the air con fan.

Originally mine kicked in as soon as i turned the ignition on, and speeded up when air con was turned on? is this right?

But on trying to test the radiator fan it appears that i have now done something, and the air con fan doesnt turn on right away now, but only when air con is turned on in car??

Any ideas how to fix this?

Also has anyone got any decent guides for changing the water pump, as im not a pro at this!

any help much apppreciated !! thank you !!

I planning on switching my stock 3000gt SL engine which has about 93000 miles with a stock 3000gt VR4 engine and was wondering if anyone had any tips or any type of advice for doing this, please give me any advice you think i might need to do this!
