Exclamation 04STi - BLOWN TURBO- POSSIBLY ENGINE-HELP

Hello, my name is kyle. I am 18 years old.

Lets cut to the chase.

I have a 2004 WRBSTI.

Mods

- Slotted Rotars
- SS Brake lines
- Rota Rims
- Airbox silencer Delete


I have had this car for 3 months and 2 days ago on my way to mohegan sun the turbo blew. After driving home which wasnt a good idea, but I had to the car ran OK.

My dad and I decided to pull the car into the garage and check everything out since he was a mechanic for 20 years. The idle is HORRIBLE, bouncing back and forth from 200 to 1000rpms and ticking noises and etc are coming from the engine.

I have always changed the oil and I know since im 18 you would think I would beat the crap out of my car, well I havent. I shift like a granny to save gas around town and to keep my profile low. I was driving normaly and I needed to change lanes and get infront of a car so I speeded up a little bit on the highway and thats when the turbo went.

I bought the car from a private seller. He know alot about the car and took AMAZING care of the car and it has never seen snow till I bought it . Anyways, I really need help on anaylizing the car by what I give you for information and the video you see. I know it ISNT the greatest info for anyone who helps me, but it is all I have to offer till we take the engine out.

Btw, the car revs like crap and revs VERY slow through the rpms; especialy around 4k+. Car stalls at times while driving or parked.

The car only has 55k miles on it and it also has no warrenty.

Im hoping it is just a piston, valve, cam, or something with the blocks internals so I can just do a small engine build and replace the parts with cosworth . OF course with the little money that I have this wont happen for a while.....

Help?

Thats my video. Just something quick. I bought the car but my dad still is going to be pissed about it.

BTW, if this is in the wrong area I am very sorry. I figured powertrain for 2.5 would seem appropriate for this topic?


I suck at trying to type proper.

from the video, it sounds like you spun a bearing. when was the last time you changed/checked the oil?

have your dad or a reputable shop in the area perform a compression and leakdown test.

also, fill out your profile.

Ouch....Certainly doesent sound like anything to do with the turbo. Good luck man...Lookin like ur gonna be pullin that motor for a rebuild dude! Judging by that smoke it could be coolant leaking in through the head gasket! check ur oil and coolant levels! ps - I suggest towing it anywhere to get fixed!

Yea compression test for sure, after seeing all that smoke out the back. Let me just say that is the best post I have seen regarding motor failure. I am so sick of the "OMFG WTF iz wrong wit my motor yo? I PUT on THIS TITE CAI and exhaust with NO TUNE and went street racing and now my CAR IS PUUKING SMOKE!!!!111" posts.

Best of luck to you, if you are "hoping" it is catastrophic so you can get a cossie build I think you are ok

Ill deffinatly get a compression test and a down leak test. While my car is sitting atm, I will probably clear my lights and MAYBE put it 105mm halos/angel lights since they are only 20 bucks and ship in 24 hours.

Im hoping that nothing serious is wrong with the car and my block isnt cracked or some catastrophic failure in the engine. I know the turbo has gone to crap, I must of spun a bearing then it got wobbly and then the blades must of hit againts the inside walls and tore its self apart.

The engine is another story. I didn't notice any wrong with the engine when i very first blew the turbo, but when I started it today it was just shot.

I really would like a complete build cosworth 2.5 shortblock from rallysportdirect. That way I can just drop it into my car and get a GT35R or GT30R /.63 since the spool is amazzzinggg.

I really hope it all works out.

All in all I will deffinatly take pictures of everything and get diagnostics of my cars condition for you to see.

it's most likely NOT the turbo. all that noise is coming from the internals...spun bearing, rod knock, etc.

Haha, It is deffinatly the turbo too. My friend knows alot about cars and he checked it out and he told my my turbo is fried. I heard my turbo blow on the highway seeing how the extremely loudness it made and then I lost complete boost and I heard it all grind up and now I have no boost.
Yet alone even any vacuum. My dads a mechanic too he just took a quick look and is sure it is blown. I think I would rather have my cars turbo blown then my whole engine. Either way, It is going to be ripped apart tomorro morning and we and I WILL find out what's wrong.


Like I said, new build was be nice..............


Btw, the money thing, Im waiting to sell my impreza and that money is all going to my STi. I was suppose to buy a gt30r /.63 , powerenterprize 850cc, walbro fuel pump, top mount fuel rail lines, exhaust, perrin stealth FMIC, and a safe tune on 93oct. Now, It's new ball game. Idk, Right now I need to focus on getting my car analyzed.

Since your car is stock and have a 5 year 60k mile powertrain warranty, why not take it to a dealer? That's if your 5 years hasn't expired on your warranty yet...

If you only have 55k miles, you still have the remainder of the factory power train warranty which is 5yrs/60k miles...

listened to the video, your turbo is shot. Thats the sound of the compressor or turbine scraping against the compressor or turbine housing.

I HIGHLY recommend NOT starting it up a gain for any reason. The compressor scraping against the housing could send metal into your engine. When you swap out turbo, please remove the TMIC & run water thru the TMIC from the outlet side to hopefully get any metal out of the IC that could be in there.

I would also search for the 'banjo bolt oil filter' thread & go ahead & replace it while you have the turbo out. There's a reasonable chance that it is what caused the turbo to fail in the first place.

Definitely check on see if warranty will cover it since the car is pretty much stock.

You are my savior. I got flammed on so much on CTsubie.com and people just made jokes and what not.

I will deffinatly do what you told me and I really hope everything goes well.

Problem is, Why is my idling all effed up? Is it because my sensor is shot? I have a compression tester already, my dad owns one so im going to do that and a downleak test too.


Thanks for all the help -to everyone-

why not? Subaru has 60k/5yr warranty on engine/drivetrain unless you are beyond the 5yr from purchase.

Everytime the compressor chirps the airflow is interrupted causing the MAF sensor to go on a roller coaster also the turbo could be leaking oil into the IC cause some poor idle issues as well. Once you get the turbo replaced & nothing shows to be wrong with the engine the idle should clear up. I wouldn't worry about the compression checker just yet, replace the turbo then see how she idle, etc. If there is still problems do a check.

The OP looks an awful lot like a PM I got on youtube

And like I said in my response, do the poor mans compression test (rev the engine with the oil fill cap off and check for smoke/pressure). And let us know if your oil light is on... sometimes these turbo failures can be caused by bigger issues like oil starvation.

Alright. So that explains my car idleing really bad. What about the car not being able to rev well? It takes forever just to rev to 3.5k. I wouldnt even attempt to reach 5k. A lot of smoke comes out = turbo bad. I know that for a fact. Ummm,

That sums it up I guess.

- Bad idle
- Smoke
- Poor Reving.
- What about stalling constantly? = MAF sensor im guessing?
