^ one of my friends actually just ordered some for his v7 rsti. Using a Dom 3 twin scroll to go with. I can post results after he gets tuned at efi logics.

Hi guys this is my experience with a Kinugawa TD06H 60-1 8cm 2.4" on a built EJ25.
Honestly for the money you pay for these units, there is nothing you can really complain about. Definite value for money, and they come with everything you need i.e lines, fittings and gaskets. More importantly the quality is also there. However I'm the process of going a rotated PTE 6262 :P

The top sheet was on pump 98 (93US) on 20PSI
The bottom was on pump E-Flex (E70-80) on 20PSI (Actuator was limiting the boost I could run)

I love these turbos but something isnt right with your setup...

Also looks like pump gas map is pulling timing at about 2900rpm.

Flex fuel graph is pulling timing at 5700-5900rpm then gives it back.

Whats your AFR?

Have any WOT logs?

I have a brand new kinugawa 18G turbo with billet wheel on my 05wrx.
hyperflow tmic
900cc injectors
40mm EWG
and lots of other bolt-ons. Thinking i was better off with my vf48.
This turbo spools till red line but doesnt really hit hard. If i had to guess, i would say that im close to 270hp. Feels great though.

I almost feel like my unfinished tuned VF52 pulled better then my Kinugawa 16g on my 2008 Wrx. Also Dynolicious said I was 2/10th of a second faster with the VF52. But they both blow the TD04 outta the water.

Well the vf52 is the same size maybe a touch bigger, and has newer and likely more advanced bearing and aerodynamics.

The 18g is not going to have as much torque as a vf turbo but it will give you a lot more topend with linear response. I went from a vf52 at 330whp to a td06sl2 20g 8cm at 400whp and the vf52 had a lot more torque punch because it spooled so fast but fell on its face almost rite after. I will take all the topend hp over a quick torque spike any day.

Andy Forrest (THE MAN) mapped it this morning.

TD05H-20G Billet with STS 9 Blade Turbine
HRC 340l/hr Fuel Pump
3 Port Boost Solenoid
3" Straight through Decat Exhaust
K&N Panel Filter

Made 391 BHP and 368 lb.ft Torque. The car ran out of Air and Fuel, but the turbo was still going.

Andy thinks with FPR or bigger injectors and an induction kit I will see well over 400bhp. Cracking Turbo and plenty at the top end, was pulling strong well past 6500 RPM."



Here are some pictures

Hi, Im Ricky from Scoobynet UK & have been looking into these turbos as an uprade for my current setup. In particular the new Kamak STS TD05H GTX

http://kamakusa.com/kamak-sts-td05h-...in-scroll.html

I have a JDM Impreza Sti 2005 widetrack EJ20 2.0litre on a VF36 with a few stage 1 mods. Though the STS TD05H GTX billet will spool a little better than the on the graph quoted above, I still think it may be a bit laggy? The graph above seems a good comparable & IMO it is hitting max torque rather late & spool seems very gentle?? ps note that the UK graph quoted above the figures are at the flywheel not whp.

Any thoughts much appreciated as I have already emailed Kamak USA, Taiwan & Steamspeed asking which turbo they feel will give me good spool characteristics and approx 380whp on a 2.0litre engine? So far Kamak USA & Taiwan have suggested either TD05H 18G or 20G. Still waiting for Steamspeed to reply.

As a comparison my VF36 with forge actuator, figures at flywheel:
340bhp @ 5,600rpm / 365 ft/lbs @ 3,200 rpm, at 1.55 bar peak boost.
It holds 1.5 bar from 3,100rpm to 5,000 / 1.4 bar to 6,000rpm / 1.3bar to 7,000rpm.

Will the Kamak turbo I am interested in be a big improvement over above figures in terms of bhp/torque & also spool?

I think the one you quoted is a single scroll and you linked to a twin scroll.

Oh sorry for confusion, I am interested in the twin scroll version & understand your point. The twin scroll should spool better but is the single scroll still not rather laggy? It is a pity I cannot find much information of these turbos being used on 2.0litre twin scrolls?

The chart did seem a bit laggy, but we'll see how he does with new injectors.

I think the TD05H-18g will have the best trade off for daily driveability and performance. I think you would see decent gains, but I don't think I could say it would be a "big improvement." You should probably think bigger than an 18g for the big impovement.

The TD05H-20g would probably be best for your goals. You could consider a TD06SL2-20g for more power, but the torque may peak after 4k on a 2.0l; still, it would be making power to redline whereas the TD05H might be running out of steam. Go with the TD05H-20g if you want more power between 3k-4.5k. Go with the TD06SL2-20g if you want more power between 4.5k-8k.

Retune on E85 390hp and 404tq.

The original Dyno was of just the open dump on the EWG, the two graphs you see below are of the pump gas retune and E85 retune with a custom exhaust wastegate muffler added on. I managed to make back all of the power and then some on E85 but on pump lost about 30 hp and tq from the change. Keep in mind the original tune was I think from March so it was a bit cooler in the shop than yesterday.

My original idea was just to route the dump back into the downpipe but was advised against this from my tuner and my exhaust fab guy. The first revision was just a pipe routed out of the engine bay at each bend the pipe diameter increases and we had hoped this would sufficiently muffle the sound but it was still way too loud, for SCCA I have to keep it under 100db @50 feet and some sites 95db. A muffler was added to the mix but I think it's too restrictive as I am loosing about what I was told what I would lose If I had plumbed it back in. SMH

For now I'm keeping it as is, I will be either replacing the muffler with something else that sless restrictive or just putting a vband right before the muffler so I can run the straight pipe then If I get dinged for sound just Vband the muffler back on and take a hit power wise.

Big thanks to Dave Brown at Performance Auto Solutions for another awesome tune!

Results are great! Exactly what I was looking for in an Autox build where spool is of great importance. Thanks for selling configurations of turbos other companies won’t.

Cant wait to see what it does on E85

Thats weird to see e85 spool later than 93.

I'm not sure why you would loose any power muffling the ewg, at most too much restriction on the ewg exhaust would just cause boost creep.

I assume he is tuning around the boost creep? Not entirely sure how it works but he told me for every extra foot of pipe even it affects the power level.


Thanks Ian!

You can't always get good spool information from a dyno chart. It depends how the dyno is setup. Most often, they are loaded lighter than your actual car would be on the street, and they consistently show later spool than you'd experience in the same gear on the street.

Some dynos more closely match street loading, but in my experience most of them show later spool than a datalog of a street run in the same gear will show.

Unless you have history of that particular dyno with a familiar turbo, I wouldn't try to make spool comparisons from internet dyno charts.

Thanks for finally posting this!

Are you sure that an open dump pointed straight down to the pavement would exceed sound requirements?

Have you considered something cheap and custom like attaching a glasspack straight to the WG outlet? See below

http://forums.nasioc.com/forums/show...php?p=17397692

(see post 86, 87, and 90)


I bought the car this glasspack was attached to. Since purchasing the car three years ago, the non-flex Uppipe finally cracked at the welds (on both ends! ) and so I replaced it with an Ultimate Racing v3 flex up-pipe. This is the one that comes with their flexible stainless steel dump tube. (http://www.ultimate-racing.com/xcart...0&bestseller=Y)

I will confirm here, that the difference in sound of the open dump through the glasspack vs the sound through the stainless steel flex section was VERY noticeable. The glasspack really did muffle things quite a bit, comparitively.

Maybe this can help you try something different and free up the power again. Good luck!

I had seen some of the stuff posed in that thread but I need the exhaust to at least exit the engine bay for the rule set in SCCA. For some reason I feel like I have the loudest EWG dump I've ever heard, I think the choppiness of the gate adds to the DB level.


Here's a video of me running it with just the pipe that runs out the side before I added the muffler, the video doesn't really capture how loud it is since its pointing away from the car.

I'll be playing with different ways to suppress it to really maximize the power definitely a different muffler in the future but for now I'm just going to drive it for awhile and enjoy it.

Dan Im not sure what your running for a muffler but a lot of folks are running the supertrap with good results. Manitou on here has a 44mm piped all the way back to the rear diff area and a supertrap on it. He has a larger turbo but is pushing some pretty good ponies with it.

I'm actually not entirely sure what the muffler is I have to find out. Originally it was supposed to be a straight through kooks race muffler but when I went to pick up the car they said that one didn't fit and put something else on that has baffles in it. Almost looks like a stock piece off a 911.

Coming from TKX I wouldnt be surprised if it was. Obviously dont mean that in a bad way. I just know they have alot of the Porsche stuff as they convert so many to full blown race cars.

Look into the supertrap. its tunable with multiple disks for more flow or less noise.

You've got some serious flutter going on...how could you drive it like that? Its gotta be effecting performance..

^^^ Im not sure but that "may" have been before the car was tuned for the EWG. I could be wrong though.

Since the rule is that it must exit behind the driver, you can extend a pipe back to right behind the plane of the driver's seat, then angle it down at the ground. So for instance, in the posts I previously suggested, you could add on whatever length of pipe needed to get it to be behind the driver...

Is it already pointed at the ground? I've heard this makes a big difference in what dB you register at the sound meter.

Enjoying the convo here since I am going to come up with something myself for next season; upon further reflection I am not sure if my dump tube currently goes as far back as the driver.

For whatever reason Dave and TKX said to stay away from the super trap? That was one of my first suggestions just based off what I see everyone here doing.

When you drive it it pulls smoothly so IDK? I know in the configuration it was in for the video it was down more than just the 30hp that it ended up loosing after they tuned for it.

Correct, although it did flutter very similarly even with just the short dump

I actually have it extended back to dump in front of the rear wheel, partly because originally we thought it could just be a straight pipe with some bends for sound reduction and now because its a good spot to have the muffler so its not hanging down too low the pic above is pre muffler, the one thing I should still do is have the tip pointed down, I'll figure that out when I tryout some different mufflers I'm just going to have a small Vband put in so I can change them out I think. the ricer in me was thinking of keeping it straight so I could put it through the big side skirt that will one day be there. Like this


Heres a shot of my downturn its not vbanded on in the above shot.
