Flawless, tuner was also impressed by the low latency. I really believe these are the same exact injectors the big names use but mark way up since their sticker is on it.

I guess I'd also like to chime in as well.
Spun a bearing in my 06 sti. Made the decision to make a tad more power. It has hard to find any hard evidence reviews of the arashi turbos, minus a few Evo X posts I had found (all positive though) decided to pull the trigger.

I wanted something that was good for daily driving, but also had enough for up top as well. I REALLY wanted to break 400whp too.

I decided on the td06 20g 10cm2 w/billet wheel upgrade. Also has the grf housing (for better fitment onto the intercooler coupler)

My build consists of:
Perrin wing stiffies
Power stop z26 drilled and slotted brake kit
Act streetlite flywheel
Act xtss clutch kit
Cobb front and rear shifter linkage bushings
Group n poly transmission mount
Perrin front sway bar endlinks
Hks hi-power full catless turbo back
2013 sti tmic
Perrin turbo inlet
Perrin 3 port BCS
Spt Intake
IAG AOS street ( installed at 175,6xx)
Gimmick Silicon rad hoses
Flatout suspension sr52 coilovers
Cobb v3 accessport
Cobb 1000cc injectors
Aeromotive 340lph (installed at 176k)
Aem wideband
Prosport oil pressure & boost gauge
Tuned on 91 & e85 by Eric at Torqued performance
293/315 on mustang dyno (91 octane before rebuild)
Iag stage 2 short block
ARP head studs
Tigwerks oil pickup
Iag wrist pin and cover seal kit
Tial MVS 38mm external wastegate
CNT EWG uppipe and dump tube
Iag top feed fuel rail kit and braided fuel lines
Side feed tgv deletes
Arashi Td06 20g 10cm2 w/billet wheel upgrade
Perrin 4 bar map sensor
Iag billet timing belt guide (red)
Port matched heads, tgvs, intake manifold
Ebay billet oil fill cap
PTP Red turbo blanket

I feel like this is the RIGHT turbo for the 2.5L.. It has what I feel like is even better daily drivability than stock turbo (it hits 3-5psi of boost before 3k rpm, and 21psi at 4k) and pulls 21 all the way to about 6k tapering to 18.5 on 91 octane. (not completely finished with the tune either)

So far I'm about 1500 miles into the new motor/setup and it's been fantastic all the way so Far.

I'll see if I can get a link up to for an album for those who are interested.


**edit**

***link***

https://photos.app.goo.gl/TjbKNp88aBKSPzdWA

Here's the link for some pictures I've compiled from my rebuild. Car has NOT seen any dyno time yet.

Currently finishing my tune on 91 with Eric minehart from Torqued performance.

Will be going e85 after that hoping to make ~360on 91, and 400+ on e85.

Any update on your turbo? My TD05H-18g 7cm^2 is coming today and I'm probably going to delay installation until I have time to tow it to a tuner. My coworker said that I can run the Cobb FP18 map as a temp map to get to the Yimi Sport Tuning, but I'm not going to risk that (he's blown his EJ257 before from overboost) and rather have AAA tow me there instead of towing me to a mechanic.

What is your current set up? I installed my 750ccs last and the morning before the tune I flashed an oem map the only change was to pull back the duty cycle for the new larger injectors to make it driveable, no other changes and it started right up. I just drove it very easily and stayed out of boost and it drove fine.

Save that AAA tow if you can, especially if you only get 2 free tows per year, I am glad I drove myself there because I ended up using the free tow home after my ecu bricked on dyno.

Almost forgot, you may need to change injector latency values also to make it driveable to the dyno. This is all assuming you are coming from oem injectors and use opensource to tune.

I cant wait to get one of the new arashi journal bearing stock location 3071r turbos for my other ej205. Ive put 8k miles on my arashi 18g and hit 24psi multiple times a day and it hasnt shown any signs of slowing down.

Very happy with mine too, Arashi is good shizzz...made in Taiwan is NOT the same thing as made in China.

I'm currently on the stock 06 injectors which are ~565cc (I know it's a 2.0L subforum). I'm probably going to limit power potential by keeping them stock for now, but everything else I have is an 04 STI TMIC, Perrin turbo inlet, DC Sports short ram intake, CNT catted downpipe, HKS Sport exhaust, Grimmspeed EBCS, Cobb OTS Stage 2, and a Walbro 255lph fuel pump.

On a side note about the "mysterious eBay turbo," I emailed Arashi support asking them about the CHRA manufacturer, and they responded saying that it's made in-house by Arashi in Japan.

Seriously what fuel? I am making 350hp/340tq at the wheels on 16-18psi on my 18g. I wouldn't feel safe going any further on my 91 pump gas. 24 psi is well over 400 crank hp! Are you using meth injection or e85?

I am very surprised I am making this kind of power on stock TMIC, stock exhaust manifold and stock airbox with drop in filter. I see no need to upgrade these things because I figured I was already at the limit of the oem internals.


Oh and by the way turbo is working out great here too, no leaks or bad noises.

Ethanol ***128513;. Almost 12k miles later and im currently waiting on a new clutch from south bend. The exedy stage 2 hd didnt want to hold all the torque. Started slipping 2 weeks ago so i turned it down to 20psi.

On another note i have arashi dynamics gt2835 8cm sitting on a shelf waiting to go into my other wrx.

Im pulling the engine out next weekend to do vc gaskets, the clutch/ flywheel, and an oil change haha. Ill pull the turbo off and inspect it while i have super easy access to it.

I finally installed my TD05H-18G and 700cc injectors yesterday paired with my Clark Tuning etune. With the preliminary map, it runs really great and full boost comes on at about 3200rpm with 70% IDC. I pulled 18psi until letting off at 5k rpm. I'm not sure what this map's max PSI is, so I wasn't going to fool around until I get a good revision. So far, so good!

Here's my 1st revision on e85 with Eric from Torqued Performance.

I know virtual dyno isn't the greatest but with only 11whp between smoothing 1 and 6 I think this is close to what it would read on a dyno. (20lbs, corrected for elevation) uncorrected it read 430ish whp

What wastegate spring are you running? Does your WG flutter under partial throttle? My Virtual Dyno reads 318hp/324tq with smoothing set to 1 at 20 PSI with a Clark Turner e-tune, but I get what I assume is wastegate flutter at partial throttle rolling on acceleration. I read somewhere that the Arashi turbos come with the 10lb spring installed by default, so I'm not sure if I should hit up Clark for another revision or increase the spring pressure by swapping springs.

I'm actually running a tial 38mm EWG. I'm running a 14lb wastegate spring in my wastegate and it still flutters partial throttle.

Looks like you're running an overall larger turbo compared to mine. I'm running their TD05H-18G 7cm, but you're getting that flutter like me on the 20g. I'm gonna hit up the tuner but he'll most likely charge me again since I'm outside of the 30 day window. I'm still trying to wrap my head on how the EBCS is working in conjunction with the adjustable wastegate during mild acceleration. At first I thought I was experiencing compressor surge or the bypass valve was fluttering, but it sounds and feels more like the internal wastegate is fluttering under partial load.

I put the 12lb spring in my 18g the morning of the dyno tune. I had to look up the spring color guide as Arashi doesn't provide it with turbo. I posted the chart on page 2 I think? No fluttering issues here and boost comes on violently even in first gear. I highly recommend removing the wastegate and mounting in a vice to change springs....you can do it on the car but it's too easy to strip the cap with the provided wrench.

Side note: I am putting wrx up for sale this week if anyone in the Reno area is interested. Price not set yet but will be around $7k. Nothing wrong with the car, I just don't love Subaru like I do Nissan and Honda.....so I am going back to my roots of lightweight and simple cars. I prefer an inline four or six with actual compression.

Datsun is calling my name again! 510 with a raceport 20b anyone?

Used to have a 72 Datsun 620 truck semi modded L20 swap. I chose it many times over the S2000 parked next to it to drive to work. Both fun cars but in different ways.

Currently installing an arashi 20g, did you change the wastegate spring from what came installed. And if so could you give an explanation of how.
