I am about ready to install a new TDO5 20g 7cm turbo on my 2.0. I have everything except inject. I am still not sure what size to get. anywaz. If you have a TD05 20g 7cm turbo on your stock 2.0 engine....post results. If you would...also include injector size. Thanks guys

A little Laggy but who cares, I also want to see what 2.0 20g are doing. I personally have 18g 8CM and the lag isnt that bad coming from VF22. I can live it a little lag and more topend. Its great.

dont get injectors smaller then 650s. My buddy had a tdo5 20g on his 2L and it made 330whp on a dynojet @ 22psi and then spun a bearing......

hhmm?..is there a lesson there?

780 cc..650 you would come close to static idc...

No lesson.....my car made 330whp and ran great for months untill i parted it out.

I havnt driven a 20g 2.0 with the TDO5 7cm yet. But from what I hear....It spools very fast for that large of a turbo. From what I get from owners its like having a 16g with 350whp capabilities.

I"m interested in seeing some number's also.I'm split between the td05 18g 7cm and td05 20g 7cm.

+1....good thread. about time we get some of these going,

any chance 8cm people can post too?

I know they are here..........

im interested as well, i know there are some folks out with these setups

i think a td05 18g with a 8cm housing would be perfect

i think a td05 18g with a 8cm housing would be perfect

imo it's either that, or the 7cm housing with an external gate.

i personally would go with the 7cm/ewg combo, but some folks can't abide the compromises.

I run a TD05H-20G/7cm^2. Search my username in PPB forum. I'm NOW running an EWG incombo w/ all the mods in the list. 326whp/292wtq w/ the IWG.

My buddy (WRX2FFU) made 311whp on 93, and 347whp with 110 with an sbr 20g on a Mustang Dyno. He is using modded wrx injectors. It's on a stock ej20, IWG.

yeah....from what I have heard and gone through with my big16g setup, the EWG makes a huge diffrence. When you have a turbo that big on the 2.0 with such a small IWG, there is almost always some degree of boost creap. This happened to me with my BIG16g setup. I put down 250whp at 16.5 whp. THE EWG not only solved this problem, but also allowed for increased psi and boost control. In fact, after I added a big TMIC and went EWG, I put down 315whp @ 19 psi! IMO, This TD05 20g 7^ EWG 2.0 setup is one of, if not the, best street setup for the 2.0 WRX

holy sh**!! 315whp on a big16g?!?

Thats right....... And belive it or not it was on a set of 565cc injectors to! They are a set of Deaschwerks and my tuner said they were flowing like 700cc or something. He had to take out a ton of fuel. 315whp on a BIG16g isnt actually all that it is limited to either. The turbo is......

Big16G..

(550cfm, 36 lb/min, 275-360whp, Bolt-On) This water cooled direct fit TD05H-16G-7cm2 turbocharger has a compressor flow rating of 510cfm and an unheard of compressor efficiency of 77%! This makes it the perfect low-cost easy install option for your 330whp 2.0 Subaru project.
The inlet and outlet flanges of the turbocharger are a perfect match for the stock flanges and high quality carbon steel studs are included so you don't have to scramble for hardware during installation.
The compressor inlet of the turbocharger is 2.4", so it is directly compatible with the factory air inlet tube and doesn't require expensive aftermarket intake tubes to install. The 2.4" inlet is ASME spec bell machined to maximize laminar flow into the compressor wheel to reduce inlet turbulence and improve compressor efficiency.
The FP16G comes fitted with brand new coolant lines and an 8psi wastegate actuator. The oil inlet thread is 10mm x 1.5mm just like stock, the water threads are 14mm x 1.5, and the oil drain flange is the same size and bolt pattern as the factory TD04, TD05, and VF series turbochargers allowing the use of any of these oil drain tubes.
Expect to achieve full boost with the proper mods and a quality tune between 3200-3700rpms. 2002-2005 WRX owners will need fuel upgrades for this turbocharger and proper engine management is highly recommended for all vehicles.
Purchase $850

It drives me crazy when people get to a point with their turbo where they dont feel like milking out the rest of the hp that it is capable of. I have had fun with this turbo but the 20g still looks like more of what I am looking for overall. The TDO5 anywaz. Its just like those guys that get great hp and times with thier TDO4's. They put in the time and there ya go.

Anywaz...back to the topic.......TDO5 20g 7^ results

Keep us updated! I'm still split between the 18g and 20g.My tuner told me to go with the 18g that the 20g is a little to big and alot laggier on the 2.0.

i want to know soem good suggestions. im pretty tied between turbos.
i got a 05 2.0L wrx and lookin for a turbo kit.
out of the 18g's whats ur guys' take on the most efficient and best overall.

thinkin of the td05, gt30, or maybe an IHI so i can run anti lag.

whats the best ta slap on?

thnnx for some input.

anti lag =\

anti lag= hard on your car...really hard on the stock motor, its intended for rally cars or built up street cars that can handle the extra stress... IMHO anti lag is dope but not for a daily driver...

I too would like to go with the 7cm EWG

So nobody has experienced compressor surge on spool up with a td05-20g? I'm tuning a friend's 2.0L WRX and I have to limit how quickly it spools up or it surges.

i'm not surprised, shek... that's a big cold/small hot arrangement.

cow dungs that's fast!

I have a 20G 8cm that is going on a built 2 liter. I'm really pleased with the ej20 over the ej25 because of the way the motor revs. Much smoother and pleasant for a DD.

I would have said better the ability to start in 2nd and stay in 5th gear down to like 35mph makes the 2.5l better for a DD, but ok

i just installed a Deadbolt TD06H-20G turbo; Monster ported, clipped turbine wheel, for EWG, 7cm, red ceramic coated compressor, black ceramic coated turbine housing, with a tial 44ewg and a turbo xs uppipe, spearco top mount, perrin turbo inlet, big 3 inch short ram intake with all other supporting mods have to wait for my injectors yet then getting dyno tuned was kind of curious what i should expect for full spool and power seen as how im on the 2.0 bought all this off a fellow nasioc member

save yourself some headaches... buy a sti block before a huge turbo... the 2.0 is never gonna last... i learned from experience. bye bye bearings

I have a 20G 8cm that is going on a built 2 liter. I'm really pleased with the ej20 over the ej25 because of the way the motor revs. Much smoother and pleasant for a DD.

I would think the opposite for a DD.

A 2.5 with 20g on a DD is gonna have way more low end grunt than a 2L, and low end 3000-5000 rpm is for DD so i dont see how a 2L is better in any way.

A 2L with 20g would seem more suited to higher revs since its gonna be way laggier.

I had a 60lb/min turbo (granted thats much larger than a 20g) on my 2.2L wrx and it sucked as a daily driver.

My 2.5L Green is perfect for a daily IMO. Anything 49-52 lb/min (Green, SZ49, Dom3, gt52) are killer DD's for the 2.5L

Get some PE800's. Im running them w/ my FpGreen on my stock 2.0Ll and made 360whp on 23psi on our local Mustang Dyno.

Wrong. Pushing 340whp out of an 1820 for coming up on 2 years now and 50k on the setup(100k on the motor).

^^ I'll bet thats 340 dynojet hp ;)

its only a 36 lb/min turbo, so 360 crank hp.....~290-310whp

^^ I'll bet thats 340 dynojet hp ;)

its only a 36 lb/min turbo, so 360 crank hp.....~290-310whp

It has been on a variety of dynos ranging from 309-360. The 1820 flows 630cfm, which I think is more than an 18g but less than a 20g.

I have trapped 112mph knocking in 4th, btw so the power is there.

630 cfm = 43.47 lb/min

20g = 44 lb/min

I really dont think it flows that much. You're making less power than most vf turbos on race gas.
I say less power because the vf39 can get the 3350 lb STi to traps of 110-115mph

You're getting your 3085lb car to the same trap so you have to be making less power.

If Jr says the car should of gone 116mph the Ill believe him:D Either way, I am making more power on a used and abused 2.0l than what people give it credit for. Its not the highest amount but just cause its a 2.0 doesnt mean its going to break at the first sign of power. I was just upset by that blanket statement that the 2.0 cant hold crap.

There have been so many threads posted inbetween this one getting lost for a year. There are many people running low to mid 300 wheel hp 16g, 18g, 20g on a stock 2.0 with stock transmission and some even a stock clutch. Hell some of them are 100k+mile bugeyes too :devil:

Dont knock the 2.0, granted that people have spun bearings ect ect but everyones situation is different (driving habits/maint. history/owner history ect) It only take a few people to say "I spun my bearing with a bigger turbo" and it spreadslike wildfire and everyone thinks that your motor will assplode if anything but a td04 is bolted on there. Be smart with your driving and dont short change yourself on the upgrade and you should have little to no worries. If you auto-X, track, time attack, drag, rally ect ect then OBVIOUSLY your gonna break something eventually. Plan for your needs and build accordingly :banana:

anyone running a td06 20g on a 2 liter engine?

i currently have a blouche 20g td05 8cm, iwg,turboxs fmic, deatschwerks 750cc injectors, inlet, intake, and aem ems.........i was pulling 270 at 4500 rpm before my clutch slipped. i have a new clutch on the way, so hopefully next week it will be in by next week and redyno sometime soon with 100 or 110 octane. i may go external wastegate next year, but am afraid the tranny wont hold up

I'm running a td 06 20g on my 04 wrx. 90k miles, stock clutch, trans and a lot of launches at the track. The clutch is on it's way out quick, but with a smoking clutch and no lc, I ran 13.1 at 108mph with a 1.9 60ft. The clutch still smells from that run 2 weeks ago. I just installed a cm meth kit and I'm getting a new clutch/flywheel next week. I'll post some good numbers after it's fixed.

I love the 20g on the 2.0l. The lag saves me gas but it's not that bad when you get on it. I reach 20-21 psi at about 4100-4200 rpm in 3rd gear. After going ton stage 2 and upgrading to a 16g, I would never go any smaller than a 20g on a 2.0l for a dd. :D

i'm curious as to how wide you think the bearing surfaces are on the 20x vs 25x blocks?

i'm curious as to how wide you think the bearing surfaces are on the 20x vs 25x blocks?

+1. I was under the impression they where the same? And if they are, that means for a given power and rpm point, the ej205's bearings are under less load due to weight alone, not to mention angular forces etc...

#'s seem really low...Ive seen big 16g's with the same if not higher numbers atleast low 300 some even 330-340 and faster spool + pull to redline. IMO if u want to save gas as a DD sure but otherwise we dont push enough air to utilize the 20g, if you have a hybrid it would be a perfect combo.


bump for more results tho

^but what are you basing these "low numbers" off of? Unless it was the exact same dyno you cannot judge if it is low or high or whatever. You cant act like you don't know this, I expect it is common information by this point...

Those dips on the other hand make me wonder what's going on there?

uh yeah pretty common knowledge not every dyno reads the same however for the average dyno results Ive seen from 20g 2.0 setups it does not convince me to get a 20g.

How is a 300 whp/278 tq 2.0L with a tmic low ? All I can tell you is that my car was considerably faster than any of the 16G powered cars around here. This was a Tim Bailey tune on Buschur's dyno by the way. The dips wre smoothed out on the next pull. THe dyno is supposed to read low but I don't know about that. Dyno numbers don't mean that much anyway. What you want is to get trap speeds with this set up to gauge it's merit. I could have easily taken my car to Agile and got 30- 40 more whp from their dyno but the car would not be any faster. The dyno they use just reads higher by design but is more precise as far as changes to the set up goes. I can almost gurantee you that the trap speed on my old set up would be consistantly higher than any 16G set on the planet without meth meth injection. There is no secret here. Bigger turbo more power. The tdo5h housing and 7cm hot side is not huge. The 2.0L can defintely push enough air for it. I had to ditch it immediatly when I installed the 2.5L as boost was just about uncontrollable. Full TQ by 3700 rpm is not laggy to most either. I am going to build a second subaru when I am done with the wagon. I already have a 2.0L block. I am for sure going to build it to rev to 7800 rpm and put another tdo5h/7cm 20G on it. I have to go with my personal experience here. I have owned it and driven it. It trumped my vf34 in every way. I have also driven just about every 2.0L turbo combo you read about on nasioc from vf22 to 18G. I am simply convinced by my hands on experience.

OH SNAP!!!! Yeah, your power band looks pretty boss. Love it!

I am about to purchase a TD05 and a Utec... lightly modified as of now. Actually the TD04 is blown and need to purchase one. Should the Utec help protect the car before I get the other mods needed to upgrade? or should I worry about the other mods before purchasing the Utec?

OH SNAP!!!! Yeah, your power band looks pretty boss. Love it!

Oh yeah, the 20G blew my 70k mile 2.0L. I am now running a Blouch D1 and a hybrid 2.5L. I sold the turbo to another guy with like 60k on his 2.0L... boom again LOL ! That is why I am going for forged rods and pistion on the 2.0L I am building. I plan to drop that into a GC wagon or a 2.5rs if I can find one.

Excellent. This gives me an idea of what to expect from the 2.0L I am building. It also supports the fact that my old 2.0L set up was very good. You say my numbers were low but I lacked the turbo inlet and ewg you were running. My turbo was not ported or polished either nd my intake was and still is sucking hot air from under the hood LOL ! Combine that with the difference in dynos and what have you got ?

For instance. I used to run a vf34 tuned by Bailey on Buchurs dyno. I made like 272 whp. My friend made 305 on Agile's dyno with a vf30. Our cars ran almost identically in the real world . This was confirmed by many passes at the local flashlight drags.

At any rate looks like you have a killer 2.0L set up there. I have graduated to a 2.5L and a FP greeen sized turbo but I plan to revisit the 2.0L 20G combo for another project. Your 371 whp regardless of what dyno that was used encourages me. I am going for more than that but plan to build the motor to rev to 8000. I will not spin it that high but if you look at my hp curve it is still clinbing at red line. I think it could stand another 5-700 rpm before it falls out of the efficiency range. Nice job on the opensource tune by the way.
