New WRX turbos? TD04? TD05?

free5ty1e · Post by **free5ty1e** » Thu Jul 21, 2005 1:53 pm

OK, so I'm still asking these kinds of questions. What turbos did the newer WRX's come with? If I come across a 2002 WRX turbo for a reasonable price... should I get it? Or is it a TD04? I've seen some listings with 2004 WRX turbos and they aren't TD05's, and they aren't IHI's...

I don't care about the compressor 90* inlet. I'll take care of the compressor side.

The USDM WRX has the TD04L-13G. Not much of an upgrade over the VF11.

Which years came with the TD04L-13G? I definately do not want that turbo. The VJ17/VF11 hybrid I currently have is better than that.

So far I just know that '93-'96 WRX's came with the TD05H-16G that we all want, with the 90 degree compressor inlet and all. But I know the same turbo was on other WRX models, just with a straight inlet. I can work with either, and just want to know what year ranges to look for when searching.

Well, all USDM MY02+ WRX's have the TD04L-13G.

I've seen a list of what turbos came on previous WRX and STI models, from over seas, in the past. I'll see if I can dig it up.

Looks like MY94-MY96 had the TD05. Then for MY97+ they went to the TD04. I'm not sure if the older TD04's are the same TD04L-13G's or not but would imagine they are or at least are about the same and not worth the effort.

You might want to think about a VF23, VF28 or VF29. Or maybe the VF30 or VF34. They all have the straight inlet though but once you go through the effort to use one, you'll be able to interchange between all the bigger IHI snails.

Or just get a TD05H-16G and call it a day.

I thought the USDM WRX turbo was a 13T? Either way it's smaller than a vf10 which is the same size as a VF11 but with a larger compressor outlet, I certainly wouldn't waste money on it. I agree with just getting a 16G and calling it a day. There's a lot of power to be had from one of those.

Chris - I don't think the TD05H-16G was ever made with a straight inlet. The straight-inlet ones you see floating around were modified to fit newer cars.

If I'm not mistaken, 93-96 WRX sedans/coupes came with the TD05; the wagons had the TD04. 93-96 STis also had the TD05. So your happy hunting ground is 93-96 non-wagon WRXes and STis.

these 16g tdo5h turbos did not come to north american cars, so looking for one in scrap yards will be a waist of time for me. so what turbo can i get from a scrap yard that is the same? i will do custom work to make it work i dont care.

Ahh... the straight inlet Subaru TD05's are FROM the 93-96 hunting grounds, and have had the 90* lopped off. I see now...

Yes, that was all I was making sure of - my hunting grounds. I want a TD05H-16g but I don't want to pay more than like $400 for it, and that's if I don't have to rebuild it.

The IHI turbos are vast in selection, this is true... but they have such limited data available on them that any selection I make in that group would be based largely on speculation and what people "think" that turbo flows. I'd also probably have to modify the uppipe/downpipe in order to fit the turbo in there at a better angle to make the straight inlet work, and that's not mentioning the wide variety of turbine side flanges to adapt to.

Ya, I know that most odd designated mitsu compressors are usually designated T's and the evens G's but all mentions I've seen of the TD04L had 13G not 13T. But hey, that doesn't mean that it isn't really 13T. People also call the EJ22T an EJ22G.

THAWA · Post by **THAWA** » Fri Jul 22, 2005 2:43 pm

Heh, yeah.

I also agree that the lack of information on IHI turbos is very frustrating.

ok so what i got here is the 16g didnt come to northamerica right?

so if i put the tdo4l on my car, could i swap out the inlet fan an the houseing like i did with my vj11 vj17 and make a 16g some how.

why is everyone on this board say its so hard to make the 90, all you got to do is welled on the factory one or make a custom made one and put it on. its so easy.

The turbo is a td04-13T, there was a thread on it at awdpirates.net a while back.

Nico - you can weld aluminum? Heliarcing is a relatively rare skill to have.

I don't think the TD04 cartridge will accept the 16g compressor side. Otherwise we'd see TD04-16g's all over the place, seeing as to how rare the TD05 cartridge is.

THAWA · Post by **THAWA** » Sat Jul 23, 2005 3:20 pm

The TD04 definately can take a 16G compressor. Don't the PT Cruiser GT and Neon SRT4 have TD04-16G's?

NICO · Post by **NICO** » Sun Jul 24, 2005 1:01 am

my dad can weld it, free i live in the steel city of canada i got all types of resources in this city. if i had to take it to get it welded it would cost 20bucks

Aluminum isn't steel. Two completely different things. If you have the resources in the steel industry you can probably locate someone to weld aluminum, though.

NICO · Post by **NICO** » Sun Jul 24, 2005 11:44 am

im saying i live in a steel city, and there is lots of place that do custom work on aluminum.

Whoa... TD04's can accept the 16g compressor??

OK, time out.

TD04's are all OVER the freakin' place. And, they're smaller turbines so they should theoretically spool up a bit faster. The question is, will the 16g perform anywhere near the same with a TD04 driving it instead of the TD05H? Let's discuss this.

Edit: It seems to me as though the downside of a TD04-16G hybrid turbo would be the inability to upgrade the compressor any further (17C, 18G, 20G, etc). If that is the only downside, I'm makin' me a new hybrid. I just got a 16G compressor housing and wheel in perfect condition

Are we SURE the TD04 turbine side will mate right up to the 16G compressor side? Can anyone else confirm this claim?

free5ty1e · Post by **free5ty1e** » Sun Jul 24, 2005 1:15 pm

OK - Jerry at Deadbolt sez:

"With a LOT of machine work we can make the 16G wheel fit the TD04 turbine shaft. We have done this before for some clients. We have to machine the back of the wheel, press a sleeve into it, machien the front hub, then rebalance it. Then the front of the TD04 cartridge will have to be machined to accept the larger diameter of the wheel, the compressor housing will have to be machined to accept the larger wheel as well. Depending on which TD04 it originally was, we also might have to machine the front cartridge insert."

So, I'm still lookin for a TD05.

Another disadvantage would be the imbalance of a compressor that flows a lot with an exhaust housing that restricts a lot (the reduced exhaust restriction is one of the advantages with a TD05H-16G). The TD04's internal wastegate also may be rather undersized for this kind of application.

I was riding in a PT cruiser GT yesterday. It has a TD04-16G, with the way the car is setup, it felt like my car feels with the VF11. Quick spool, pulls hard up to the high midrange, then feels like if falls off. It doesn't throw you back into your seat, but then again that could be attributed to a number of different things. I guess if you wanted to compare it to other subarus it felt like it had the power of a wrx, with the spool of a LGT/OBXT. Not really something I'd spend my money on.

What turbo does the pt cruiser come with stock?

THAWA · Post by **THAWA** » Sun Jul 24, 2005 10:53 pm

TD04-16G

This is a cool page:

So the center section on the PT Cruiser's TD04LR is different from the WRX's TD04L's.
