i really want to see a vf39 comparison, get to the dyno already! curious to see the topend as well. if the hype is true, for 425 bucks seems like a descent alternative to a used vf turbo. only time will tell...

I'm wicked stoked also to find out what she can do, I can't believe that Deadbolt got the rights to call their TD04 a "Monster" haha, IMO... PT's turbo is the real monster-in-a-TD04

BTW it's not hype, it's just Subie Innovation...

To clarify, it's not a td04hl turbo with 19t upgrade, Performance Techniques starts with a fully rebuilt TD04L (seals ect.) --- adds a TE04H wheel in the hot side and a 19T wheel for the compressor; as well as putting in a heavy duty thrust bearing. She's all balanced and ready for boost in a 2.0L rex

It's a great price when thinking about buying a VF39/16g, and you can still sell you own stockie TD04, so it's actually not that expensive at all.

I paid $422usd shipped (w/out heat coating).

The quality is wicked nice, James is a really good guy to talk to at PT (he does most the turbo builds). They will also heat coat your turbo for $70usd yay!

...after reading the entire thread, so you know what we're after, what we're all about, and have all the facts in front of you, then feel free to PM me some questions. No worries. Happy TD04 Tuning!

Cheers!

ForesterWTi,

I wasn't trying to ask silly questions but I have been following this thread for sometime now and I have read everything in this thread twice. This is why i decided to purchase one of these turbos... I will be getting it tuned by the end of the month. WOW... people can get really touching on this forum! I thought this place was for friendly conversation and knowledge about Scoobies but maybe I have the wrong impression. I apologize if I did something wrong.

What I'm interested in seeing is how the larger wheel performs in the small housing.

You'll have less turbine area not being occupied by the blades, so less ex. gas can pass by the blades without hitting them. Now this will obviously make your spool up very quick, but I'm worried about your top end. That's part of the reason people clip the turbine blades, to provide more top end flow. So in theory, if your on the stock diameter IWG, this problem should be even worse for you.

Think of a turbine wheel spinning at exactly the RPM needed to achieve your boost target. Now extra unneeded EGBP previously would have slipped by between the housing and the blades and IWG, but now more is being forced under higher pressure out of the IWG and against the blades of the turbine.

Thoughts?

wait, how is this turbo holding 20lbs of boost to redline? is it the altitude, what am i missing here?

stop heating the air. you are pushing the turbo WAY to hard. notice the change in maf g/s from 4-5k, then 5-7k. 5-7k changes almost nothing. maf flow should increase as rpm's increase, all the way to redline.

^^^ Actually the 19T compressor wheel is operating at ~70% efficiency under the conditions shown in the datalog above (PR~3.0 @ 450CFM). The problem is in the small hotside.

The only reason the turbo can maintain 20 psi to redline is greatly reduced VE. In order to maintain the flat boost profile shown in the datalog, it was necessary to ramp up WGDC (and therefore EGBP) with rpm. As a result of the higher EGBP, the air flow through the engine is reduced (at a given intake manifold pressure). The lower airflow through the engine allows the turbo to maintain high boost.

The end result (lower MAF through the engine)is no different. However, the above data was collected to characterize the performance of a clipped and ported TD04-19T at operating limits. It's important to evaluate data posted in this thread within the context in which it is given. Obviously running the turbo under these conditions is not recommended.

I thought it was quite common for smaller turbos (VF39's on STI's, TD04's on WRX's etc.) to not have much of a change in MAFv from 5500 RPM onwards. I know the engine RPM is going up, but VE is going down, and the turbo can't force in the air like in the lower RPM's, because the compressor can't maintain that higher pressure towards redline.

I agree about heating the air though, but in the winter with a good intercooler, your charge temps won't be dangerous. So if you don't mind pushing your turbo to the edge then the extra MAFv might be worth it to a person.

I completely agree with you on this point. A much larger WG will be required to control this turbo and prevent overboost in general and boost creep at higher rpms. An EWG would be the safest bet, but if ForesterWTI's modified IWG will flow enough, he may be able to control it adequately.

In anycase, i urge caution when tuning this. Start out with low WGDCs and slowly move them up as you get a better feel for how the turbo will react.

I just received an e-mail reply from Performance Techniques saying that they use the TD04H hotside wheel, but it appears they have also said they use the TE04H wheel... I wonder what the true answer is.

After thinking about the larger turbine wheel in the stock housing question a bit more, I have changed my mind about my previous post. In order to fit the larger wheel into the housing, it will be necessary to bore out the turbine exit. As a result, the exit area will increase (~15% increase for TD04H wheel and ~35% increase for the TD05E wheel). This should allow a higher flow of exhaust gases through the turbine, both increasing turbine efficiency, and preventing excessive back pressure and control issues.

Low-end performance should still be good (but not as responsive as the stock hotside), since the exhaust velocity entering the turbine will be higher than that seen in a TD05H hotside at low engine speeds (low exhaust energy).

Upper range performance should improve over the TD04-19T with stock turbine wheel, both due to higher turbine efficiency and better balance with the flow capability of the 19T compressor.

I just wish there was proof of what PT uses as a turbine wheel. I was about to buy one from them and now there is a conflicting story of which one they use. ForesterWTi was told TE04H which is much much larger than the TD04L, but I was told by them that it is the TD04H, which is only slightly larger than the TD04L.. (as mentioned previously in this thread TD04L<TD04H<TD04HL<TE04H)

You know...I think your right. I was thinking more about that too.

I would still be happier with a larger wastegate, but maybe this will turn out ok.

I'm really looking forward to seeing some results. (and verifying which turbine wheel comes with the turbo)

I am basically in your boat at this time, I have been watching this for a long time and I am curious to see how it all plays out. If it truly is the larger TE04H and all that, this should turn out to be a fun DD turbo for the 2.0

Does either company port the wastegate, wouldn't that help some? I know its not "bigger" but it should help none the less.

Side note - Performance Techniques needs to make a user account and throw out some information on here. This could help clear up any misconceptions and could increase sales in the end and thats not a bad thing either.

I will continue to stalk this and see where it goes.

You didn't do anything wrong, and I apologize if I came off as anything but helpful. It was a late night last night, and I've been getting hit up with a lot of PM's that can be answered from reading. Happy TD04 Tuning!

Thank you so much Wolf! The info is greatly appreciated... I just want to make sure that I spend my money wisely and do things right the firsttime around if you know what I mean. thanks again.

Well everyone. I just bought one of these turbos from Performance Techniques and I will be installing it very soon. I hope to have it tuned by the end of the month. Supporting mods will consists of Cobb SRI,Afta-maf coupler, turbo inlet, Catless up-pipe, 3in Catless tbe, 565cc injectors, 255 fuel pump, large tmic, Performance Techniques TD04 turbo, 3-port or mbc which the tuner decides on in this area. I will more then likely going to a tuner that uses open source to tune my car. I hope I can stick with the internal waste gate because I don't really want to go thru the trouble of doing a ewg setup. I heard the hot is to small so it could cause some issues.

But all-in-all I hope everything turns out well and hopefully it will be a nice DD. I decided to go this route because I want a fun street car with quick response and low end torque. I'm not looking for a high hp car just something that is reliable and fun to drive. I'm hoping that I can achieve around 275ish or so to the wheels and some good torque. I don't want to brake anything though because this is my only car. I will let everyone know how it turns out.

If I'm missing something in the mod dept. please let me know but I think I have bought everything I need to support this upgrade?

Performance Techniques does port the IWG that was a huge reason for me buying this TD04 from them and not someone else. In conjunction with my true divorced DP that is VTA, IMO I should be able to control this turbo.

Also, in regards to the hot side wheel issue, whether it's a TD04H or a TE04H either are bigger than stock. I just wish it was the TE04H, I was under this impression until now. I am going to cal James at PT to get this all sorted out.

My point any bigger wheel on the hot side, as long as it's bigger, I would buy especially over the option of clipping the stockie wheel.

Check out the later post in this thread about my IWG that uses a true divorced DP that is VTA. IMO I think my prototype DP coupled with what I'm calling PT's TD04L "Monstah" is a perfect match for a 2.0L rex DD.

This. Still a much cheaper option than Blouch, also including wg porting, and I like the idea of a larger wheel opposed to a clipped one. Also sounds like it has some better internals instead of just a rebuild. I would just like the conflicting information coming from the same company cleared up. I will be a little disappointed if it is only the TD04H like I was told instead of the TE04H like others have been told, but it won't change the fact that I will be buying this turbo.

Default the dark side

My project name for this GF8 is "Pink Vader" (3 layers of matte black w/ factory pink Rota Formula 18x8's) so it's only right that I sway to the dark side of the force haha. Yeah I hate/love to tell you guys/gals that I will be taking the bump up to The E85 Army

So I'm going to run 750cc injectors/255 fp with the PT TD04L "Monstah"... and yes a full tank of e85 fuel. I'm apologizing because so many people didn't even know about Performance Techniques, and were waiting on my dyno pulls, but now they will be tainted with corn

Cheers,

p.s. I get on a dyno ALSO at the end of the month

I think there are still a few people popping in and out who don't completely understand what the 19T upgrade to the stock turbo is supposed to accomplish. The whole point is that its an intermediate upgrade. Its going to provide more power than stock while providing better response than a 16G or VF39. Anyone expecting fantastic peak power and amazing results from a TD04L-19T is mistaken. Its not going to happen. If you want peak/high rpm power you need a larger turbo.


The big question right now is the 19T turbo from Performance Techniques. Two of us have been told that they use a TE04H turbine. One has been told its a TD04H turbine. There isn't a whole lot of difference between the two. In either case the result is going to be an improvement in high rpm flow. Both have a larger exhaust opening and will allow for a larger volume of exhaust gas flow. Obviously the TE04 is better for high rpm flow than the TD04, but both are an improvement over the TD04L.

TD04H = 2.04" inducer, 1.74" exducer
TE04H = 2.01" inducer, 1.88" exducer

First off, thanks to you and ForesterWTi for all the info.It is a little overwhelming but not to bad once it all sinks in. I would think that I am like alot of people who are following this thread, looking for some more go but not spending out the wazoo to do it. I want a better mid rpm punch, I rarely run mine past 5500 as it is. $ per $ you cant really beat it for what my goals are, yeah I could buy a used VF series but again its used and lord only knows about the seller & the real condition of the turbo. For less than 500$ I can get a "new" turbo and get another 100k out of it and not have any worries.

I have a fair amount of parts stocked up, just need to figure out the turbo and then the injectors to go with it.
About 8k ago I did a oem clutch and streetlite flywheel, should be able to handle the 19t for a good while (driver dependant).

Mods eventually will be,
3tbe, GMS turbo inlet, spt intake, ssac tmic that is on the car.
Setting on a shelf right now,
grimspeed crossover, headers, GS 3 port EBCS, fuel pump.

Default Perfromance Techniques' "Monstah" TD04L

OK guys/gals I called James at Performance Techniques (909-824-1020) to get down to our question at hand...

When you buy their turbo, for the hot side they use the TD04H wheel.

The confusion was started when scooby921 had never heard of this company when I posted about them, he emailed/called PT to get info. When he did this they must have said what they told me just now:

"We will install ANY wheel a customer wants on the hot side and compressor side of a TD04." -James @ PT

So when scooby921 asked about the TE04H wheel they must have said yes we can put that in for you, not yes this is what we put in for their ebay sales of this turbo.

James also went on to tell me that the difference is so small, even on a dyno you will not really notice anything between a TD04H and a TE04H. PT does not currently have anymore TE04H wheels in stock.

I then went on to ask about, then which wheel does come with their TD04L turbos via ebay auctions, he told me that it is the TD04H wheel for sure.

He also added that if I wanted bragging rights: the TE04H wheel is actually smaller than the TD04H. He said that he had read some of this thread due to gaining response and interest --- and was worried about the misinformation regarding this wheel size issue.

So I just clarified it

James furthermore, would like to apologize for the web site, not being Subie savvy, but he does not yet have a web designer, and would like to assure all of us that this is a great company and in the meantime to just give him a call direct --- he'd be happy to answer questions and take orders for their "Monstah" TD04L turbo.

(PT's number is at the beginning of this post)

Hope that clears the air in here.
Cheers,

James,

Thanks for the reply and thanks for the link to the ebay page. That shed a little light on things, but I still have more questions. If you don't mind me asking, which turbine wheel are you pairing with the 19T compressor wheel? Is it a TD04H, HL, TE04H, or something else? Are you machining the TD04L housing to make it fit or are you starting with a larger turbine housing? And pending that answer, are you open to doing other custom builds?


There are many of us on NASIOC.com who value turbo response over peak power. A lot of us are looking at the 19T upgrades as a way to get more power and still have stock-like response from the 2.0L motor. On the 2.0L motor the stock TD04L-13T can make 15-16psi by 2800rpm with some good tuning work and put 220-230hp to the wheels. With response like that its hard for many of us to upgrade to a larger turbo as we have to sacrifice response to get power. Depending on which turbine wheel you are using for the 19T compressor I'm concerned about the loss in spool characteristics. I'm sure I can make 300whp with a TD04HL-19T, but I'd rather make 280whp and hit peak boost 300-500rpm sooner with something a little smaller. If I'm looking for 300whp and peak boost at 3500rpm there are quite a few options already available...TD05H-16G or any of the IHI VF30/34/35/39/43.

At the moment there doesn't seem to be a middle ground option for the 2.0L Impreza WRX owners. It would be nice to have some options available between the stock 13T and a 16G. Is it possible to put a 15T or 16T compressor wheel on the stock TD04L turbine wheel? Is it possible to fit the TD04H wheel into the stock TD04L housing and build a TD04H-18T? What would a TD04H-18T cost?

Also, do you work from new components only or could I send a turbo to you for modification? I have a stock one lying around that has some pretty heavy port and polish work done on the turbine housing. Assuming you can put a larger turbine wheel in the stock housing I'd imagine some amount of the porting work will remain useful for the new wheel.

Thanks,

-Brad

Hello Brad,

I believe the td04h and td04hl are a bit too large of turbine wheel. I uses the te04h wheel for this upgrade. I can do
a 16t upgrade compressor wheel with the stock turbine wheel for $325.00 rebuild included. I cannot do a 18t as I do not have a source for
those wheels. I use all new parts genuine mitsubishi bearings seal etc. The compressor wheel I have made because the avaiablility from
mitsubishi is terrible. I can work on your turbo no problem .

Thanks

I'm quite certain they told me they use a TE04H. And yes, the TE04H is smaller by 0.03" at the inducer...but its 0.14" larger at the exducer. Regardless, it seems they've finally confirmed things and also confirmed that there isn't going to be much performance difference between the TD04H and TE04H wheels.


Wolf, I'm still excited to see what you get for results
