Hello everybody, I'm Italian and I just registered to this website because I'm finding lots of information about TD04 turbos.

I own a Renault Megane R26 (2000 cc with TD04L6-14T 8.5 originally developing 230 hp ATF) which I tuned with a larger front mount intercooler, samco hoses, ITG panel filter, decat, bigger injectors (deka siemens 630cc) and a very good map.

Now the car has about 240 hp ATW and something more than 260 ATF (I tested the car on 2 dynos, one gave me 243 ATW and 275 ATW and this one - pict below - 239 ATW and 260 ATF).



Black line it is my car, green car it is a Megane like mine but with a Garret GT28RS (low boost due to gas temperature) instead of TD04.

I really really like the way this turbo is spooling fast, producing 441 nm (325 lb ft) at 2900 rpm and pushing well until 6000 rpm (when hill climbing she's fantastic). Max boost now is 1.5 bar (21.7 psi) in sixth gear at (something less than 3000 rpm..checked this morning).

Now what I'm lacking is high rpm power. I sometimes use the car on the track and she's is quite dead above 6000 rpm (tuned NA civic type-r with 250 hp ATF are going better than me in straight line due to their shorter gear ratio and high rpm power curves). What do you suggest? Is there a way to maintain quick spool at low rpm and higher power at 6500/7000 rpm??

The company which did my map is now "producing" an hybrid conversion of TD04 machined out to HL and 16g or 19t comp wheel.
The problem will be that with that sort of turbo the car could not go over 1.0 bar (14,5 psi) or 1.1 bar (16 psi) because at that boost she will already develop something like 487 nm (360 lb ft) and pushing the boost further will mean the risk of melting pistons or braking con rods.
Further than that, at that sort of boost the power increase will be of a mere 8 or 9 hp and will be developed always in the range between 5000 and 6000, so not a big gain at all over 6000 rpm. In addition it will result in a loss at low rpms.
The only way to achieve more power with this turbo in my car will be forging the engine (but for the moment I don't have this intention) and go for higher boost 1,3 bar or more.

Anyone have some suggestion (at the moment I have no intention to consider swapping the turbo with GT28RS because, as you can see from the graph the power loss will be immense at low rpm)??

I'm really sorry for my long message and story. Hope to find some friends here

My suggestion is:
trade in your Renault Megane R26 for a Subie WRX 2.0L

This makes sense, if you consider that at low engine speeds, the exhaust energy (temperaure and pressure) is dramatically lower than that available during spool-up. Any reduction in turbine impeller surface area should be expected to significantly impact energy recovery and therefore availabe boost pressure at low engine speeds. As the exhaust energy increases during spool-up, the turbine housing size may be the dominant factor in terms of available boost and whether or not the exhast wheel is clipped may be less important. This seems to be supported by the above observations.

(3) In theory, an unclipped TD04-19T paired with an EWG should significantly extend both the bottom-end and top-end performance. This may not yet be demonstrated, but it seems very possible that such a combination would outperform a small 16G and perhaps even come close to matching the top-end of a large 16g. It is very tempting to pursue this, but we are really only talking about an additional 10-15% gain, and the added cost and effort for me can not be justified at this time. The added noise of the EWG is for me an additional deterrent to going down this path.

Ken
^^THIS! Its what I've been saying all along. Port the heck out of the hotside, don't clip the turbine wheel, and get an EWG.

For me this summer, that will happen. I already have:
grimmspeeds EWG uppipe w Tial 38mm EWG
790 cc injectors Modified stockers (balanced and flowtested)
Walbro 255
3" TBE
Spearco TMIC
3-port BCS
an extra TD04 laying around

I honestly would do it now, but I simply don't have the time to devote to installing it, tuning it, and sharing info with this being my senior year working on my engineering degree and working a job.
---------------------------------------

Knuts, could you post some MAFv logs perhaps? 20 psi is a LOT at redline at 6500 ft. Even for the 19T wheel. I guess thats why you didn't see the MAFv go up after 17 psi.

Thanks for posting your thoughts and experiences with this turbo!

My turbo is almost done...modification is complete, now I just have to wait a week for it to get coated. This is taking a bit longer than the 10 days I was quoted. Oh well...UPS is having trouble delivering my clutch anyway. They can't seem to find the damn notice with my signature on the back. They stuck a second one pretty much on top of the first one .

i have put three of these on customers cars now and with a good tune i think its well worth the money. The last car made 280whp on out dynojet on gas and an open ecu tune

Thats not bad. At 6500ft your doing well. That first log is what my MAFv is on E85 on a cool night maxing out my TD04. I'm at ~1000 ft ASL. If I did the 19T modification I would hope to go from ~4.3v to 4.7v here at 1000ft.

Thanks again for posting those logs. Your helping the rest of us make up our minds

Who's coating it, same guy who did the wheel upgrade?

Any pics?

I could read in some other page, but did you PnP the TD04 or are you not going down that route?

UPS messed up on the delivery of my clutch also, BUT they put it in a car outside the shop garage thinking it was one of ours! The guy just drove off later that day with my $1000 clutch/flywheel 2 race helmets and shoes haha crazy ordeal. no track day that week though!

I've been a UPS employee for a year and half now oops lol
I'm a night load/sorter so you all can't blame me for driver's mistakes

is there still really a market for td04's? they really provide that much more down low over a vf39 or 16g?

YES. REALLY.

You are 16 pages deep in a thread solely based for dedicated people with TD04's making close to VF39/16g awhp/awtq...

or a twinscroll gt3071?

Don't get me wrong twein scroll is great but if you read this thread through, we don't want to spend that type of money. This is all about daily drivers that are quicker low end through mid, i.e. daily driving.

And btw the way we have people on here pulling 20 psi with TD04 up to 6500, e85 is amazing timing on subies...

I'm on a mini lap top this screen is wiicked small so I prefer this format much more

I could read in some other page, but did you PnP the TD04 or are you not going down that route?
The guy building it is handling the coating. I'm not sure who is actually doing it. He sent me the PM yesterday and said it'd be done by the end of next week. Its either going to a really busy shop or its getting boxed up and shipped to a very specific company.

The turbine is P&P. I posted pics a couple pages back. My "donor" was a Deadbolt Monster TD04. I'll post up new pics next week or weekend when I finally have it in hand.

As was said, some of us like the quick response and easy driving characteristics for daily driving. If my car were just a toy and not something driven 100 miles a day I might think about going bigger. The twinscroll is cool, but its not something I wish to spend money on. Not only do I have to buy the turbo, I have to buy the headers, uppipe, and a new oil pan. My total upgrade, clutch included, is less than $1300.

I've done my research on the 19T and a big 16g/evo3 16g and the differences aren't that large. I plotted boost/rpm performance for 6 or 7 different 2.0L evo3 16g's that I found dyno charts for. There is some variance, but it looks like the 19T is going to build boost 300-500rpm faster and should flow 50-80cfm more by 3000rpm. Across the mid range they are going to make equal boost and should provide very similar power. Assuming the 19T falls off up top due to turbine limitations the 16g will flow 30cfm more above 6000rpm. Considering most of my daily driving is 2500-5500rpm I'm ok with the difference up top. I'll take the low-end response and its still making more power up top than the stock 13T.


One of these days I'll join the hunt for big power. I have an EJ22T block in the corner of the garage waiting for me to find enough money to do something with it. I have dreams of ported and cammed heads, high CR pistons, and a 49 or 52lb/min compressor. Until then I'm going to stick with turbos that fit inside your's .

Oh wow, I forgot you started with one of the deadbolts still floating around, it's a shame they went under... but it's given us ideas of tuning with TD04's and most of all the HP/TQ we like daily

Yes comparing a twinscroll setup to something we have stock is like apples and oranges, especially in terms of money but for the price a I'd say we are not doing too bad at all --- only 30cfm more for hundreds more --- haha

I had a 98 leggyGT with whybrid motor --- STi block/VF22 ect ect, ran bumper to bumper with an 04 STi twin vf39'ed at 160mph! (he was wicked pissed to see a 98 in his mirror through the whole pull ) That was the only taste of builtness that I've had... FUN but expensive.

Nice suggestion, shame that until now, apart from spec-c which flies, all subbys (STI, don't know how WRX behave) I found on the track were not so impressive, maybe it was the driver (but I'm a normal driver too), maybe the weight or the power loss ATW due to 4x4 traction, maybe the fact they were original (really don't know).

I'm sorry I cannot find videos, beacause I have some in which I overtake them easily both on the straight and on the first corner, but I think you wouldn't believe me anyway...

Of course they have lots of positive aspects, in drag racing for example they always left me behind in standing start, and the way they put the power down with the 4 wheels attacking the tarmac is fantastic.

I posted just to know your opinion and I thought someone could help me with the choice of the turbo because many people here are writing about TD04, but I was wrong.

I'm really not a fan of any badge, I have simply chosen the best car I could afford in the Hot Hatchback segment, maybe if I had that sort of money I could have bought a subaru and enjoyed it, but I didn't.

Leave you in peace.

Bye.

This is the route I've decided to go for a turbo upgrade on my 2005 WRX. Beginning to collect all the necessary parts. What are the thoughts on tuning it? I currently have an AP v2, but was figuring I'd find a different way to tune the 19t setup and sell the AP. Are there any compelling reasons to try and tune this with the AP?

Nope. You can't use the AP to tune it unless that's all your tuner uses to tune with. Otherwise, sell it and use that money to pay for the tune.

Apologies for not reading the whole thread. But has anyone done a back to back comparison of a TD04HL-19t and a standard vf39?... Judging by the datalogs, these two turbos act very similar on a 2.0L engine... Reinventing the wheel can be fun. Or you can just buy a used vf39 instead.

No one has done a direct comparison. I don't think anyone even has a TD04HL/19t turbo on this thread. It might beat the VF39, the TD04L/19t is close.

They are different even if dyno numbers and logs don't show it. Buying a used VF39 is an option, but the modded TD04 will not be the same. This mod is much older than the VF39 swap, just check out the 3000GT, Saab, and Volvo communities.

{Read some pages before this.}

I have both stock wheels upgraded: a TE04H and a 19T in a TD04L...
The TE04H wheel is one step away from the TD05 small 16g wheel. It's the largest wheel you can put into a TD04L. I'm waiting on ported goods before I roll a dyno. (Which is WICKED soon! My GF8 is going to be mean, especially because now I'm going to tune with e85 ) I went with the TE04H wheel because I do not think that clipping the stock hot side wheel is the right way to go about gaining rotation/CFM's. This wheel will hurt just a little bit of my low end but mid range will be amazing (I can't hardly wait to see how long she'll pull till she tapers off, compared to a stockie 13T, or the 19T upgrade). Not to mention, finally a TD04 WITH top end...

P.S. It's the Performance technique's turbo.

Oh, whooops. I meant, TD04L-19T. Basically, a stock 2.0L WRX turbo with this mod. I don't doubt this mod is old. From what I've seen, both this turbo and a VF39 spool the same and make the same power up top. And a VF39 costs a lot less and you get to recoup some costs by selling your stock turbo...

SELL SELL SELL the access port and use the cash to get a good pro open ecu tune, although it's a stockie turbo, the 19T isn't the same for AP tuning... Let us know when you get on that dyno!

What are you running on your 05er?
Whats your target boost, awhp/awtq?

ForesterWti,

I sent you a pm... I was wondering if you read it yet? I was wondering if you could comment on the quality of the td04hl-19t that you bought from Performance Techniques? I was thinking about buying one. thanks

Firstly, you should, and anyone else at this point in the thread with this same question, read the WHOLE thread haha, all this info is in there, and good to know guys/gals...

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!
