3. On a stock block 205, ewg, 93 oct, fmic, hallman, 11.5 afr.........when do you believe it would hit full boost.....if you had to guess?
My 20G was a 47 lb/min turbo. This is rated at 63 lb/min. There are too many variables to say when you will reach full boost. It depends on the gear you are in, how high your EGTs are, the plumbing to the turbo, etc. On a 2.0 its going to a bit laggy. In 4th gear on my STI I expect full boost after 4K rpm. In 6th gear, right under 4K rpm. I would guess on a 2.0, somewhere closer to 5K RPM.

However, this has a rather small A/R and a lightweight, larger comprssor wheel compared to my 20G. I won't have a good answer until all of my new parts are on and the car is at least rough tuned.

The ports are anti-surge ports. It helps between shifts when the BOV/BPV opens to not reverse the the compressor wheel's direction (pressurized air can flow and circle arounf the surge ports). I was getting surge on my 20G with my TXS 50/50 BPV. However, the TXS 50/50 BPV made boost come on 400 rpm earlier and less WGDC was needed. The stock BPV is not designed to hold boost past ~14.7 PSI. On high boost applications, the surge ports are an aid in the time the BPV takes to pop open and act as a damper, prlonging the life of the turbo.

That turbo looks nice, I will strongly consider one of these next year when I upgrade turbo's. I only see one 16g on their site though

Can't wait for the results.. even if they're on a rough tune for now.

Anyone run one of these? I'd think it'd be good for more than 370bhp

Don't trust the HP ratings ebay has listed. Most of them are too low, or just a guess. I don't know why this is, but I have seen some dyno plots from one of the tuners Kamak uses and I recently gave him some tips to get more power out of the car. Use this site and this site. The better number to look at is CFM. Also, download the Kamak 2011 catalog from here to get CFM and lb/min (although you may want to convert the CFM to lb/min yourself).

This particular turbo is a copy of the original FP Green with twinscroll. It should have more low end than an FP Green and ~375-400WHP on a 2.0 (like an older FP green can). Of course this is highly dependent on your other mods. Since you will have to get the twinscroll headers, up-pipe and downpipe, it should get close to 400 (I always quote Mustang numbers). If you add the billet compressor wheel, it will spool even better.

The old FPGreen is the same as a 20G but with the 11 blade TD06SL2 turbine wheel. For reference, below is my old 8CM^2-20G on E85 when it was fuel and clutch limitted (built EJ257 with many aiflow mods; you can see where the injectors go static in the curve).

I am only clutch limmitted now (injectors replaced with 1100CC FICs), but all of my new mods will be on within a month (I am just pulling the engine to do it all and upgrade the head bolts to ARP instead of the stock stretch bolts).

E85:



I can't wait to break 500 ft/lbs of TQ. This is why I went with the more TQ of the 25G vs the 60-1.

I need to compile a full mod list. I will after this round of upgrades is done. Parts are still arriving. I plan on pulling my engine towards the end of this month. There is a partial list on iwsti.

Another suggestion is if you buy one, buy directly from Kamak or contact Kinugawa before you buy one. That way, you are assured you are getting the latest model (and you can customize it for just a few dollars more like I did). The turbo I bought is not even listed as it had a custom wheel added and the billett WG actuator added.

It seems functional as long as the membrane does not break. I will probably fit my Forge WG actuator onto the unit instead however. If that membrane breaks, the turbo will overboost. I did get an upgraded map sensor as well, so I can start using the boost cut in case it fails. Evything else looks and feels great.
Examining the actuator a second time, I may take that statement back. The Forge Motorsport actuator does not have a sealed membrane above the spring (the nipple shown is the main input for opening the gate), but there is a threaded hole below the membrane. This could be used as you use the secondary port on an EWG with a 3 port solenoid to stabilize the spring presssure (so the WG cracks open less violently and obtains finer boost control). The hex screws could be made of a harder metal as I almost stripped one of them, but a $2 trip to Home Depot or Lowes will fix that. Also, I did not mention that inside the turbo the hole to the wastegate port is nice and contoured. I had to do the same contouring with my wife's VF39 as it had the infamous creep issue.

I purchased the same exact unit, coming from an OG FPgreen owner. I welded my wastegate shut because I'm external, can't wait to get my built block back and make some power. I picked up Kinugawa as a distributor for our side business. I mean the quality is there. Here's a mod list and I will post results once all back together and tuned.

Kinugawa 25g tdo6SL2 8cm^ hotside
TGV deletes
Synapse 40mm EWG
AP EL headers
Deatchwerks 850cc injectors
CP 8.2:1 pistons
Manley turbo Tuff Rods
King bearings
Supertech valves, dual springs, and titanium retainers
Perrin FMIC with blow thru maf setup.

I'm open source and hopefully this turbo will make some good numbers on pump. We'll see what happens. As Gabe said above I researched the brand thoroughly as well seen many different boards raving about the turbos such as SR guys and RB guys as well as EVO 9 boards using the compressor housings and wheels on there stock center cartridges with great results. Not everything on ebay is garbage, A LOT of big names also started there.

I am experiencing a problem with the oil drain flange currently, I installed the turbo had the engine started and had an oil leak coming around from the flange :/ took the turbo off and thought I had fixed the problem only to re install and the same happen's so currently have the turbo back off again and think I have to have the flange smoothed out as there might be a rise and isn't sitting flush on the casting.

Turbo is the Blouch Dom 2.5xtr with 10cm hotside.

Sorry if you already posted it, but what custom wheel did you add to yours? Where they knowledgable in assisting you with what wheel would go well with that turbo?
I currently have a Blouch 18G-XT, but I think I may be upgrading sometime in the next few months..These Kamak/Kinugawa turbos look promising, and the price is right.

Did you move? Cause FP is in McKinney...which is a lot farther than 30 miles from Austin. Was just over there a couple weeks ago picking up the new prototype FP turbo I'm tuning on my bugeye tomorrow.

Gabe is exactly right about the Kinugawa turbos, how they are made and who they are. There is nothing wrong with their quality or the parts they make. Have had one on my 88 300ZX Shiro Sport for over 7 years with no issues at all. (mine is a re-badged turbo...but still made by Kamak).

Nothing against Blouch (I'm an FP fan myself), but these guys are the real deal.

I had only good experiences with FP. My current CHRA is assembled by them and continues to run nice.
There was some feedback, years ago, that was negative in terms of communication, but I was able to spend as much as 30 minutes at the time on the phone with them and there was not one question regarding turbos that they wouldn't answer.
I'd like to see what they come up with next.

With this said, I like the fact that Kamak/Kinugawa is becoming a bigger player, because they bring a reality check as far as prices.
If the domestic companies can allign prices with them, then I will definitely change my preferences.

^ have to agree with Vlad. FP was nothing but good to me but I wanted something different and in all honesty I think some of the big guys here really need a price adjustment. I understand cost of materials goes up and what not however I have seen FP off turbos they have that are rebuilt or old stock for like $895, this includes like reds and greens for our cars. That to me says a lot, you know they are not losing money doing that. Honestly I hope this Turbo works out for me and if not still has a one year warranty on it.

How long are people waiting for their Kinugawa parts to show up?

Placed a order for a few turbine wheels on the 20th. Sent them an email asking for tracking # and I go to find out that they haven't shipped from Taiwan yet : (.

Website shows parts ship in 48hrs using USPS Express.

They make quality product.
I have reviewed with measurements every component in the rebuild kit from Kamak and will try to post the link here.

http://forums.nasioc.com/forums/show...ak+rebuild+kit

Back in the earlier days, when there were postings from FP and Blouch on the forums on a weekly basis, they were throwing lines at eachother regarding components in their MHI tubo line-up, being or not being original. There was stuff about how to ID an original MHI compressor wheel by the color, etc.
These turbo assemblers (and makers now, as far as billet wheels), use components that they... source, for housings, actuators, turbine&shaft, etc. Not always are said components MHI.
If they are not MHI, how do you know that these components don't .... also come from an Asian Warehouse, where Kamak is sourcing them?

Consider that the Japanese manufacturers, such as MHI, are starting to also outsource their labor outside of Japan...

The only thing that makes a product quality these days is quality control, origin means nothing. There is every indication (for me) that Kamak has good quality control.
Which doesn't mean that other "ebay turbos" are any good.
What I've seen and read was that Kamak turbos are sold as: Kinugawa and Kando Dynamic.
My items shipped from a warehouse in Taiwan.
Blouch gets a lot of their parts from a company called turbocam which is located 15 minutes from me in barrington nh. I know this because my friends girlfriend works there and she is the one that told me one day when she noticed my Blouch shirt. So yes Blouch turbos are made in USA.
