Crap...WTH happened?

[deletrius]

Okay...where to begin...about 3 weeks ago my T25 died on me. I bought a used 14b for $20 and put it on. Wasn't as smooth as it sounds, but i found out that the seals were shot on the 14b about a day and $110 after i put it on. So, week 3 rolls around and i desperately need a new turbo so i can get around (my car is my dd). So I purchase an Evo 3 Big 16G from the local speed shop, and since i don't have time or tools, they installed it too. So all goes well...for a day or two. Since i am on the stock fuel system the car is just running slow, too much fuel or too little is being shot into the engine for the Evo 3, i dunno i don't have the money for a logger. Last night I drop my buddy off and am driving home. As soon as I hit boost (~3000rpm, 10psi) i hear something bad, cant recall the sound, i just know something bad happened. As soon as it made this sound the power from the boost just felt gone. So i pull off to the side and notice that the idle is REALLY odd. It keeps surging, down to 300rpm, back up to 750...repeat. I go to push the clutch in and the car dies. Somehow i manage to drive it home. Today I had to go to school and work. Getting to school was okay, the idle was still a bit messed up and whenever i depressed the clutch pedal the rpms would drop. Driving to work sucked. As I was on the highway in 5th gear, i would go to accelerate and the engine would try to go faster, but it wouldn't really. No power at all. I dropped it into 3rd to see if it would have any power that way, but instead it just helped to slow me down. I noticed that when in third and i slammed the gas that my turbo would spool up to 10psi at 3000rpm, then immediately stop spooling, then would spool up a little to 5psi or so, and keep surging like this. Almost to work I am getting off the ramp and my car dies when i hit the clutch pedal, i was able to put it in third and dump the clutch and bring it back to life, but when i had to stop i had to keep a foot on the gas in order for it not to die. Coming home from work sucked horribly. I think my engine is dead. As i was driving, the same situation happened on the highway, no power at all and bad sounds, such as a really loud whirring sound. when i got off the highway at a stop light, i had to do as earlier, but it still died. i depressed the clutch and turned the key and i think it backfired like 6 times before starting, the rear end was shaking and making pop sounds. not cool. i was able to put it into first and i had to slam the gas in order for it to even start to creep along. No power AT ALL. I drive along and hit another stop light, the same thing happens again. Now when i finally get it moving the engine is making a horrible horrible nasty sound. Also, oil pressure is slowly going down. I barely managed to make it home and now i want to stab my car. any help is appreciated and thanks for reading this long post.
Also noticed that the water lines are installed backwards on the 16g, could this be harmful at all, seeing as how water is pumped through it so would the inlets be interchangeable?

To me it sounds like you have a huge boost leak, do a boost leak check first. If not pull the intake off and check to see if there is any oil or any shaft play on your turbo. Maybe do a compression check last and post results

 

[deletrius]

i realize that you shouldnt upgrade to a larger turbo without supporting mods, but i needed a new turbo desperately and i figured why not go ahead and get this brand new one since i have not had any good luck with used turbos (2 bad T25s that died after 2000 miles, 1 bad 14b that died after a day)

 

[Defiant]

You kept driving a car that shouldn't have been driven without tuning in the first place. And, once it had unknown damage, you continued to drive it.
I won't type out loud what the problem is, but rest assured it's not with the car.

 

[napkinthief]

I'd have to agree with you Defiant, but there have beens times when everyone has driven a car that should not be driven. There had to be at least once that everyone moved thier car when it shoulda been towed.

Could the ISC motor be an issue too possibly? Playing part in the RPM's dropping heavily/car turning off when the clutch pedal is pushed in?

 

[wolf20043]

Had the same problem when My timing belt slipped. I would pull the top cover and check the dowel pins if the boost leak test turns out ok.

Well, I got it towed to a local DSM shop and they say it is probably the balance shaft, there is some metal shavings in my oil so theres a good chance that my engine is dead...

 

[Mike Marnik]

if its your balance shafts your engine is not dead the metal shavings would be from the balance shaft bearings.

no! it is dead (psssst i want a 6 bolt)

Maybe you should hold off on the six-bolt until you learn how to modify an engine. Next time you think something's wrong with your car, take a bus, taxi, call a friend for a ride, walk, ride a bike, rollerblade, skate, etc, until you fix your car. If you were out jogging one day and started having a heart attack, would you keep running, or would you stop and maybe get some help from a professional?

I would keep on running... Dont want the heart rate to lower.
