Finally someone posted TD04-19T results! Well done and thanks for bringing this thread back to life!! This turbo has been on my wish list, but there has been minimal information posted.

I was really against modding my car further...but this just wets my appetite. Very nice numbers.

Was that vf39 tuned? Those numbers on the 39 seem pretty ****ty. Most tuned 39's will touch 300whp, either that one wasn't tuned at all or running 10 psi. My stock td04 put down 250whp on a Mustang dyno. A 39 flows so much more air than the hybrid setup, there is no way that it makes less power. It will be later, but should be about 20-30 whp higher. I was considering this, but it seems to fall on it's face a bit.

I'm not knocking the setup, it's very well thought out for auto-x, and it's a torque monster down low. I was considering it, I want to see a tuned 39 on a 2.0 with similar mods post a mustang dyno sheet, posted next to one of these.

My brother sent off his TD04 to have the 19T setup done with it. It's nice to see what kind of numbers he will be getting from the thing. He went back and forth on options for a while and finally decided that this was probably the most ideal. His car's a daily/auto-x/rally-x car, so the midrange ooomph is nice to have. He's ran a TD04 tuned, a VF35, and an 18G. I've always thought the car was the most interesting with the TD04 simply because it was so very spunky. I've driven it a number of times for auto-x/rally-x and always didn't like the wait on spool up. I run a NA personally, and on tighter courses, I would pull better times simply because he was below the spool range a lot. With the 19T modification, it'll be quite a little beast. His only difference is that he's running an external waste gate and wants to try and keep the smaller, stock exhaust housing, unclipped, if doable, so spool would be even sooner. Any way you slice it, the 19T's a nutty setup.

^^that would be awesome going external wastegate instead of clipping the turbine with this turbo.

that sounds like a badass setup on a 2.0. wonder how much the ext wastegate will help with spool and power up top. please post when its done

Surfer Steve - Very nice setup for the minimal amount of money spent. Any plot of the boost curve? How is boost threshold with the TD04-19T vs your old Stg2 TD04, would say its about the same?

you know I think you may come close to 300whp, albeit with extensive supporting modifications

I don't. ...31 lb/min means roughly 310 crank hp potential with this turbo setup...

Also, I'd like to know how much boost that vf39 was pushing. A vf39 flows more air and therefore should make more power with similar boost. I'm guessing the vf39 is either low boost or a crap tune like Cobb's ots accessport map.

And for that other guy, an ewg won't help spool much but would definitely help the top end with this tiny turbine housing.

My thoughts on this turbo are that if you just want ridiculous spool on your 2.0 and make more power than the stock turbo, like at a tight autocross course per say, then this is a good option. However, a small 16g would be a better street turbo IMO. It would still spool faster than you would possibly need it to, it would have more top end potential, the larger exhaust housing/wheel would provide just a touch better fuel efficiency, and you can get one for $699 brand new.

Thought I'd chime in here, since I'm doing this myself with my 04 XT (2.5L). BTW, I'm Back Road Runner's brother. Like my brother had said, I'm running an EWG setup, so my plan is to run the upgraded turbo with the stock hot-side, unclipped. This should provide some nice low-end spool while the EWG will help with the top-end restriction... hopefully resulting in a nice wide powerband suitable for daily driving and auto/x.

Also, my car's in the shop getting the engine rebuilt, broken ring land on #4, damaged heads, and jumped timing... $$ OUCH $$. With the rebuild, I'm getting the intake and exhaust ported, along with TGV deletes. All of that should help with low-end flow and spool as well.

I'm expecting around 275whp on 92 oct, and full boost under 2500 RPM. Once my car is back up and running, I'll get her on the dyno and see what my setup can do. Should be interesting

Thank you Jason, that's exactly what I said. So in theory a 39 or 16g will be a broader turbo, that makes more power. This thing is for pulling like a 67 small block chevy till 5000 rpms

But the TDO4 doesnt even fall off until around 6500 rpms. A vf39 will hit full boost at about 3300-3600 rpms. This is hitting full boost at 2500 rpms and pulling to almost redline. The vf39 drops off just shy of redline, and both turbos will hit the same amount of power to the wheels.

my buddy has a vf34 on his 2.0l and made 282 whp and 272 wtq. and this guy made 277whp and 277 wtq. i would say they are almost identical. The vf does have more up top but i cant imagine that much more that you would really notice.

I think the 16g would be a great turbo but the 16g is double the price of the TDO4. and you only get a little more up top.

Im am going to go this route with the turbo in the next month or so. I'll also be running ported stock exhaust manifolds and a 50/50 (denatured alchohol/distilled water) setup. Ill post some numbers and plots once it's all on and tuned. Might be a month or 2 though.

The difference is in the displacement. The turbo will flow the same on either engine. You'll have a certain cfm needed to spool up and a certain max cfm where it drops off. On a 2.5L, you would effectively spool up a little earlier and roll off a little earlier. the difference is simply a factor of that extra 12.5% flowing through.

i ran a td04hl-19 and then with a 16g wheel, never noticed to much difference, but with both i was getting full spool in 4th by 2800-2900 i loved the turbo, the regular td04 should spool a little faster and have a little less top end, but i have to say i was very impressed by this turbo, and anyone looking for an autocross turbo this is great, same power and spool as a stocker, but more power in the powerband

No offense, but I dont get the 16g's. Their a great turbo, but I went on cobbs website last night and looked at the graphs on the stock td04 and the 16g, and the powerbands weren't that much different.

Well, Blouch will be working on my turbo today. I chatted with them about the upgrade. For the Subarus they normally do NOT upgrade the exhaust wheel to the larger TD04HL one. However, they do a 10 degrees clip on the wheel. I also asked about not getting it clipped and he said he won't do it unless it gets clipped, as he had worries about flow at higher RPMs. He also said, from shops that have tested it, there is very little loss from the clip, and a lot gained, so basically don't worry about the clip.

Yes it was tuned, I believe it was running 19 or 20psi and was tuned by the same tuner within the same week (Doug from TopSpeed was the tuner) I have not seen too many 2.0l VF-39 WRXes with these mods run 300whp exactly how much more does the 39 flow over the hybrid setup if the 19T flows 31lb/min? and there is a way it makes more power because the facts are right in your face...

here yea go, this is a 03 WRX with supporting mods running a 16g (maybe EvoIII I can't remember) compared to the 19T hybrid. The spool is still faster it makes slightly less hp and with the TD05 hot side it fall off 250rpm later... all in all I'm happy with the setup, the 16g is a great turbo but for $300 less you really cant beat this turbo for a bang for buck on any 2.0l...





Also, I thought you guys might like seeing some side by side shots of the 19T next to a standard TD04







and a sweet shot of my engine bay
