Default Are remanufactured TD04 Turbos worth the savings?

Possibly fried my turbo recently, probably going to have to replace it. I'm a little skeptical of some of the used TD04s I've encountered online and was curious if anyone had an experience with a remanufactured TD04.

Obviously OEM new TD04 turbos cost about a grand usually, but remanufactured ones ones run about $350. Is it worth the savings?

Thanks folks

I don't have any personal experience with them as mine was replaced under warranty due to leaking seals around 80k (or so the previous owner tells me).

I've heard of members buying them used for around $100-150. As long as you're buying from a reputable source, I would assume manufacturer ones are ok. They take ones that need repaired and completely take them apart, replacing seals and whatnot.

Have any links to the ones you're looking at? We can maybe help better that way.

If you pay $350 for a TD04, I'm going to drive to Boulder and hit you. If you pay $1000... well there is no hope for you.

There is nothing wrong with a used TD04 as long as it looks to be in good shape. If you just need a replacement, go that route. With a little hunting LOCALLY (so you can look at it before you buy; take someone who's seen a few turbos and knows what to look for if you don't) you should be able to catch one for under $150. Which is really what they are worth. And you could buy 2, almost 3 for the price of that rebuild if you happened to pick up a bum one.

Now if you were thinking at all about an upgrade, now is the time... $350 is VF39/43/48 money and for around $1000-1500 total, you could do a nice turbo/DP/tune/injector basic setup.

Also, do you know why to old one died? Figure this out before you stick another one on there. If it has to do with oil starvation, get that fixed first.

Thanks for the advice guys, I really appreciate it. Hence my noobie status - I am trying to learn!

I am vaguely interested in doing a basic upgrade like you suggested KP, but I'm not 100% on that yet. I've been looking into what's required to get a VF39 installed, but I don't feel proficient enough myself yet to install those components and I figure a shop would probably try to bone me on the labor over it.

My turbo may or may not be fried, it's kind of a long story but here it is: drove into the mountains and when I arrived found a coolant leak. The engine bay was not overheating and the heat temps were normal.

Filled up the coolant, drove it back. It was leaking still when I arrived home but the temps were fine. I then drove it to a shop to get the radiator replaced, and the turbo worked 100%, but the temps were edging higher on the way there.

They replaced the radiator, and now my turbo doesn't produce any boost or spool. Can't achieve anything above 4k RPM - weak. The shop says oh ok you need a new turbo. How convenient for them. Turbo worked great, now it's fried. I doubt my car overheated and my research tells me that the head gaskets would have blown up before the turbo fried. I'm not positive though, but I don't trust them any longer. They offered a 6 month warranty on used turbo installations and wanted to charge me about $600 total. Not awful but again, no trust with those guys any longer.

Anyway, after this whole fiasco I have decided I'm mainly done with shops after this job and will do my own repairs. I would ask what is required for the turbo/DP/tune/injector set up, but in the spirit of learning this stuff, I'll do my own homework. If you have any brand recommendations I'd love to hear them!

Thanks

Did they disconnect anything they should not have while doing the work in there? Maybe the boost control lines? Is it making like 7 psi?

Any check engine lights?

It's hard to tell because I spoke with the mechanic and he straight up told me: Oh. I don't know much about turbo'd Subarus. I just replaced your radiator... nothing touched the turbo! I'm skeptical that turbo fried, but I suppose it's possible as the heat temp gauges aren't always 100%.

I haven't tested the PSI but they ran some boost tests and told me their conclusion was it was toasted. I'm not sure if it's delivering any PSI at all because when I rev above 3.5k RPM there is no change. It tops out at 4, although to be honest I have only driven it a tiny bit across town to another shop after I figured out the turbo wasn't working correctly.

Not revving above 4K seems like it's in a limp mode or something? I guess I don't know, but I'd see someone who knew Subaru's pretty quickly.

Yeah definitely. I can't even describe how depressing it was to drive my car across town like that. Basically yelling the whole time to myself, "what did they do to you?! argg!"

Took it to another shop, but this summer when I have a garage I'm going to do this s*** myself. Replacing the turbo doesn't look impossible, might just take a while for a noob like myself.

Also, again, thank you for the comments and advice.

Bring lots of WD40 when you go to replace your turbo. Soak all the nuts and bolts that touch the turbo over night and that will make things a lot easier for you. If you have the funds i would do some other things while your in there too, like a turbo inlet, your stock one is bound to rip soon.

Hi 04WRX,

Thanks for the advice! I will definitely keep that in mind. I think this time I am planning on having the shop do it since I don't have facilities to replace my own yet, but that will change soon. Eventually I'll do a turbo\injectors\downpipe\inlet upgrade, possibly over the summer seeing on how things go.

U can rebuild ur turbo as well for muuuuch cheaper.

I am about to rebuild mine, I took apart my old turbo aka desk ornament to see how hard it is and what's involved. Actually pretty easy.

Did you ever have issues with your top rad hose sucking shut after the car is cooled down?

I'm not sure, it seemed to be fine there. The crack in the original radiator where it was leaking from was at the top in the plastic piece mounted to the metal. Unfortunately I'd wager that rebuilding a turbo is a bit out of my skill level right now, but the shops just want to bend me over and make me put a new turbo in so it's ****ty all around. Going to elect to not spend $1,800 for this haha.

Can't rev over 4k? Pre-cat is breaking apart. Pull the turbo and look down into the up-pipe, if the catalyst material is touching or very close to the EGT sensor then you have found your problem.

Interesting, thank you for the feedback. What part is the pre-cat? And if that's the case, what needs to be replaced? The up pipe or the converter? Or just the sensor? Maybe all of them... whatever the case is I just feel like I definitely did not fry the turbo, but then again I am no expert.

Just heard back from the mechanic - you are 100% correct sir, my uppipe does need replacing. Do you happen to have any brand recommendations that are aftermarket worth buying, or should I look at an OEM one? They quoted me at something like $600 for it, but said if I can find a good one for cheaper that's the way to go. Thank you for this

used 2.5L uppipe if you don't need it ASAP. These will be <$100.

If you don't have time for that and are getting new, I recommend Grimmspeed. Not all their stuff is A+, but their uppipes are.

A good flex uppipe is a big friend to someone new to doing work on their car. Easier to get a good seal. Both the OEM pipe and Grimmspeed pipe have good flex joints in them. eBay flex uppipes are known to be terrible.

You will require a 2.2k ohm resistor to "fool" the ECU into thinking your EGT probe is reading properly. There is no need for this probe without the catalytic in the uppipe. You just stick this resistor in the pins of the EGT connector.
