I'm new to this site but i was wondering if any one could help me with this. Iv had my car for almost a year and the turbo went bad a couple days ago. I found a WRX IMPREZA STI 02-07 TD05H-20G OEM TURBO REPLACEMENT on ebay for $280.00."

" mods on my car are a K&N intake and GFB hybrid bov, everything else is stock. my question is will this turbo run normal on my car or will i need mods? if so what mods? or would i be better off buying a turbo replacement from the Subaru dealer?

you'd need a tune, bigger injectors, and a better intercooler, just for starters. And you'd have quite a bit of lag (with an eventual huge hit of power).

That's not what you want.

sounds pricy. I just want my car to running normal again. I think I'll just buy a used stock turbo off one of my friends and a new intercooler. or what would you suggest?

That's probably the best option for you, yes though if I were you I'd forgo the intercooler replacement unless you have a problem with your current one. If you do any kind of turbo replacement (other than stock for stock), you're going to need to do some additional modifications. These cars are very picky, to put it in layman's terms.

the mechanic that looked at my car said the turbo was leaking oil and when he took out the intercooler and turbo there was a lot of oil in both of them. i was told they both needed to be replaced

As a general rule...

When it comes to car parts, 99% of the time, eBay is the last place you want to look.

I think your mechanic is trying to hose you. Seriously.. its normal to have some oil residue in the intercooler/throttle body/turbo compressor outlet. Esp at the age and mileage on your car. I pulled my intercooler on my 2010 recently to do some other work and found a bit of oil residue... the harder you run the car the more you will get. Its normal.

Not only that.. but replacing the intercooler for some oil residue???? HELL NO.. ya just flush the damn thing out with some carb cleaner/brake cleaner or even a good douching with mineral spirits. There is no need to replace a aluminum air to air heat exchanger (all a intercooler actually is) if there's some oily residue in there. Oil doesn't break aluminum. That guy is not to be trusted, I'd personally take the car elsewhere.

Do you notice a lack in performance? does the turbo have shaft play? Are there any odd noises during boost? ...

I'm with mango, tell that guy to eff off. If you're concerned about the health of your engine, I'd take it to a specialist, a trusted Subaru tuner who will do a checkup on the mechanics and tune of the car. Oil in the compressor outlet and intercooler is normal to an extent.

Yep.. defining " alot " would help too. I've seen turbo's with bad seals spew a oil into the intake side but it was A LOT of oil.. like a pint or so ran out of the intercooler when I tipped it on its side and this was after one spirited run. (not a subaru btw) ..

Either way "some" residue is normal. Like said, found some on my 2010 (67K mi) in factory condition and perfect working order.

i think your right. that's crazy though cause I've known him all my life. anyways a couple days ago i noticed my car wasn't pulling when i change from 1st gear to 2nd at around 5000rpm (i normally shift at 25000 - 30000rpm). The turbo only spools if i redline the car. i also noticed my gas millage decreased significantly. what do you think it is?

The spooling issues, poor fuel mileage and other physical driveability symptoms DO point to the turbo.. but unless the intercooler literally has a hole in it, it should be fine with a good cleaning. Turbos are expensive enough let alone adding the cost of a new intercooler into the mix. Personally I'd hunt down a gently used factory turbo for now to get it running again and then start looking for a suitable/reliable upgrade as you save $$. Any change in turbo as mentioned will require other supporting mods and then tuning.

took it to the dealer today and im going to need a new turbo but they want to do a diagnosis on it to see if the cat back is clogged up or to see if its the downpipe and run a compression test on the engine. its gonna cost $250 :unhappy:
