new member for the dsm family and my driveway 120bucks!

[dale187]

Lets start out by saying i bought this 93 eclipse gs n/t for 120 bucks clean title and everything but doesnt run right now.. I need some help i have a few concerns but lets start out like this

Basically i bought it off a friends friend... The story he told my friend is same story he told me when i bought it so i believe him.. He bought the car from a deagle for a trade in and some cash... He said he drove it for about 2 months went to gas station it cut off... Had a hard time getting it to start but then it started ran rough, couldnt get it over 50 mph got it home and it died... Hasnt started since... We can turn it over but it will ct like its starting up and then shut off... Now i have pictures, so i was wondering if you guys got any ideas whats going on and also i think this car has a 2g turbo motor in it... And i'll show you why...

First here is a picture of timing marks... Is it out bad enough to do this? I thought the car would atleast still run...

Also take a look at this... Correct me if i'm wrong, but 90-94 motor mounts, mount directly to motor especially this one.. There is no bolt in the block where a mount would go.. As you can see someone drilled a hole to create a custom mount, but failed miserably.. Also the crossmember where the mount is runs under the motor on a 1g which this is. BUT 2g's do not have the bolt for the mount because that mount actually bolts to the transmission. Only bad thing is this also has a 1g trans so there is no bolt on the transmission for a mount neither. And of coruse you guys no there isn't a 2g with a non turbo 4g63 motor.

Now having this information i pieced this together..
7bolt 4g63t out of a 2g car, with a 1g trans 7bolt nonturbo flywheel pressure plate a clutch disk..

Here is another thing

On a 1g the mount is different than this one right? I know thats what my 99 gsx front motor mount looks like... Also again correct me if i'm wrong, n/t do not have knock sensors correct? This motor has one in the back.

If you guys have any comments or ideas please let me know. Here are some more pics of the car, and please forgive the horrid orange and blue color in the engine bay. I know its terrible

I would get that timing fixed

 

[dale187]

That is the first imma do is put it in time and turn it over do compression test... See if it bent valves

 

[cookmeup272]

sounds like a goodstart

 

[GRAVEDIGGER]

Yup... timing is way off. The mount is also the wrong mount like you said already, but it might work as long as it seems solid. As far as the knock sensor goes, I would say if there is one there then that is a turbo block.

 

[dale187]

That's what i'm saying so do you agree that that is a 2g turbo block? Since there is no where a bolt would thread to the BLOCK for amount?

 

[habitatguy187]

You can bet that it bent valves. Put a ratchet on the cam gear and see if you can turn it by hand, bet you can't or only get so far before you can't (due to bent valves).

But yes 1g nt's don't have knock sensors, that's definitely a t-belt motor mount from a 2g, and I don't know for sure about the front mount but iirc the 1g mount bracket wouldn't even bolt up to that block.

 

[GRAVEDIGGER]

That's what i'm saying so do you agree that that is a 2g turbo block? Since there is no where a bolt would thread to the BLOCK for amount?

Yeah, I'd say you are correct on that.

 

[dale187]

Ill do that habitatguy, thanks... Ill tell you what would that be why it turns over a little slow and then turns fast and tries to start? I have a spare head i can use and reseat the valves.. I'm sure thats probably all it is so i should have this car running with maybe another 100 or 200 bucks

Yeah it would make you think you have a low battery or weak starter. You can probably bet on the pistons being nicked up but you won't know until you pull the head off. Either way I wouldn't get my hopes up.

Still a smokin deal though for a turbo motor.

 

[dale187]

my uncle jumped teeth twice and bent valves in 2 dsms and pistons were fine.. i hope thats the case....

 

[Chazz1978]

Hey nice header car looks like you should just part it out looks like a headache. Sike. Work in progress.

Question asked. Is all 1g 90-94 motor mounts all the same? I know that 90-92 have a L front mount bracket. And the side mount towards the radiator bolts to the block. Oh yeah most non turbo 4g63 have a spot you can put a knock sensor. I added a knock sensor to my 92nt with out a problem already has a spot to screw them in. But it would seem if this has a sensor and is wired and the mounts to me are 2g similarity that its likly to be 2g and being 4g63 its def. 2g turbo...

 

[dale187]

Ok guys got out there today... Checked the timing, timing is dead on... Not even out a tooth... Just looked it because of where the cams sat... Went out there went to fire it up, wouldnt stay running, wouldnt even idle unless you give it gas, but it would not rev up... Now also it seems like over time it got harder for the car to turn over. Next thing i knew the starter was getting extremely hot even started smoking. Maybe a weak starter? Well i swapped starters becasue i had a spare laying around and it started turning over nice... Then after a few tries same thing.. I'm thinking something on the flywheel side is bound up, causing alot of stress on the starter and after a while the starter overheats and becomes weak for a little? That's the only thing i can think of becasue when i turned the crank with a ratchet it turned very smoothly... Also i'm questioning what ecu is in the car and what kind of injectors being as i know 150% that its a 2g turbo block. It does have a 1g cam sensor. Now since this is a 2g block and the coil packs sit just like my 2g, what should the firing order be? the same? I know on my 2g the firing order is 4 1 2 3. What do you guys think... Thanks

 

[habitatguy187]

1g firing order is also 4123 on the coil packs. It's weird that it's turning over fine by hand but burning out the starters.....

I'd go ahead and do a compression test just to see where it stands. No sense on doing a lot of diagnosing if you have to pull the head/motor anyway.

 

[dale187]

Well guys i did alot of tinkering today... Got the car to fire up and run. Had bad plugs, i pulled the plugs and there was so much fuel, it was not igniting so i took the plugs out and cleaned them with sandpaper and the car fired right up. Only problem is there is somewhat alot of noise bottom end. But i dont understand it i did a compression test and 120 to 160 across the board. If something in the bottom end went lose why would i still have compression? Also the turning over slow, i hooked a 12v 200amp charger to the battery and turned over perfectly fine. The car will idle and everything like that too. But something is lose underneath. A mechanic had mentioned maybe a bad balance shaft? Or possibly loose bearings? What you guys think. I wanted to take a video but did not have my camera on me

 

[Chaosweaver]

The cylinder with 120 is bad, anything bellow 135 isn't good.

 

[dale187]

Ok even if there was soemthing wrong in bottom end like a wrist pin broke loose or rod broke loose u wouldnt have compression correct?

 

[tunethis]

That was a great deal. The wheels alone could probably sell for atleast $120. I wonder why someone put a 2g engine in there? You say the compression numbers vary from 120 to 160? If so, something is wrong. That is too wide of a variation between the cylinders. There could be something wrong with some of the valves.

 

[ramsack]

that's a 2g 7-bolt motor. you can tell by the cam gears and lack of motor mount holes on the block, and the 2g drivers side mount. you need a 1g engine in there if you're ever going to put roll stop mounts on it. on a 2g the roll stops bolt to the trans.

 

[dale187]

Or a 2g trans, but thats the least of my worries right now. My thing is getting this motor straight with as little money as possible, so that i got still an extremely cheap beater. But dont wanna put too much into it incse i decide its not worth it and part it out. I'm going to drop the pan and check the oil for shavings. And check the torgue on the bearings. Just doesnt seem logical enough if something broke completly loose that i would have ny compresion. And i have compression across the board, even if it is 120 in one. Now can a balance shaft make that much noise?

 

[dale187]

Ok guys got the motor pulled out and stripped. Found out it was #4 cylinder bad rod bearing.. That's way it only had 120psi compression. Anyways, i'm kinda confused about something. Remember how we all figured it had a turbo 2g in it? Well i was investigating the block and there was no oil squirters in it, like a turbo block has. But i also dont understand the mount situation, because it doesnt have holes to mount to the block. I need to know what block it is to order my piston rings and what not. I wont know what bearings to order till i get crank back from machine shop. If anyone has any other ideas plese let me know
