Question--I'm looking to sell the a/c compressor from my v9 ej207 swap, will this fit a USDM 06-07 sti? I've found a post on rs25 saying all a/c compressors from 05-07 are compatible with each other, but I wanted to confirm here before I waste someone's time.

just have them take a picture of there fittings/bolt patterns for the lines that run on and off the compressor. they will either be the same or completely differet. from what i have seen all 02-07 usdm ones are basically the same deal. sold my 04jdm sti one to a guy and he put it on a forester w/o any issues.

I just got my new twin scroll turbo in from Kamak Dynamics! Here are the specs:

- TD05 Big 16G
- billet compressor wheel
- 9-blade turbine wheel
- enlarged thrust bearing
- adjustable wastegate actuator

It came really well packaged and even included a balancing sheet. Some pics on my project blog...

I'm going to run this on E85 with a bunch of supporting mods. Will report back soon

Very nice, even comes with a set of actuator springs.
The turbine outlet looks ported and polished.
I have great expectations from this turbo.
If I will use it, I will only run it on pump though. I will still get an ideea of what it can do, from your results.
I think that this turbine is effective, reducing the number of blades is one thing the VF42 had.

The install kit may be something you could look into.
I think that the purpose of that flex hose can only be to extend the reach for this turbo which is taller than the OEM.
But the restrictor is in the hardware upstream of the piece that you're removing.
I reccomend the Fp braided oil feed hose for this.

The spec sheet says 600 cfm. I'm not sure how accurate it is, but I'm going to have it tuned on both 93 and E85, so hopefully that gives us a good picture of how it performs.

Any chance you want to post how much the turbo ran you money wise? I'm looking into one of the 20g variants with a billet compressor wheel.

okay guys i got a semi trivial question
i know the pcv valve has been found to be 1/4" BSPT (british threads). i would like to use the stock iat location on the bottom of the jdm intake mani. but i was wondering what thread this one was without taking it out.

also has anyone here used the stock iat sensor on the bottom for reading more accurate iat. want to use a sensor in the intake mani or damn close. this is so far the best option but if it wont work i got a second plan in line. btw only reason i am doing this is for more accurate readings/compensations for speed density. would like to flash it on this weekend.

also anyone know the scaling of this sensor? if i remember correctly there is options for using this for the automatic ic sprayer but didnt see scaling for it....

The install kit comes with a braided oil feed. I think the flex hose is just for the different fitting size on the turbo. I'll check during the install. Here's a closer pic:



Actuator springs are: 0.3,0.5,0.8,1.0,1.2,1.5,1.7,2.0 (bar)

Sorry, by flex, I meand braided stainless flexible hose.
Have a look at the forced performance page under turbo accessories, for oil feed hose.
You'll see what I mean.
Even if what they mean with that double threaded fitting is for you to replace the banjo bolt by the passenger side solenoid with it, then thread the braided hose on top of it, over the AVCS banjo, they still have to give you a cap for the oil feed that you're disconnecting by the engine.

I see what you're referring to now. Yes, I think eliminating the factory oil restriction would be beneficial with the enlarged bearing of this turbo. The install kit provided must be just to replace the turbo hard-line section. It probably attaches to the flare coming off the oil feed from the head and the double threaded fitting goes into turbo...

hey guys, I need some help finding some parts for my V8 EJ207.

I'm basically looking for the four hoses coming off of both the valve covers - there are two on each side. I also need the "T" fitting that comes up off the block and has two hoses coming off of it. Basically I need all the rubber hoses under the hood.

I've been on the opposesforces website, and while I can find the right hand side hose, and the pictures match, the left side is different. It shows the GBOD's as being part of the hose, like it is on the EJ205 - however mine is different, it doesn't incorporate the GBOD's, it's just one solid hose.

Have any of you guys ordered these parts?

I know everyone says just go off of the 04 USDM STI - but according to the diagrams, the hoses on the left side are different.

any ideas?

I live in AZ and these hoses only last a few years before they start cracking and leaking.

Samco has a hose kit for the GDB and you can order it. The hoses will fit perfectly. Otherwise, You can use hose and barb fittings to fit the hoses yourself. I have the Samco kit on my car.

Sweet - thanks Clark.

I'll check it out.

So the EJ207 hoses on that side are different than USDM EJ257/205?
Or all they all different?



I found this...

http://www.ebay.com/itm/Samco-9-Piec...11%26rk%3D2%26

But it says WRX (says NOT '04 STI)

Where can I find this?

Ok so I'm about to pull the trigger on a V8 motor to swap into my 05' wagon with blown motor. I've been reading this thread and some other things I've searched and still seem to be confused on a few things, mainly wiring. I'll be getting the full driveline swap(ver8 6spd) w/ DCCD. No DCCD controller is included so I plan to run an after market(DCCDpro) unit.

Now with that being said, my question comes to the car's wiring harness. I know I can use the IAP wiring harness for the AVCS and the DCCD controller is going to take care of the trans. Other than that will I be good with wiring? I've read through some of the swap posts of guys rewiring the entire car from tail light to headlight with an STi harness. That seems like a ton of extra work that I'd rather not take on unless I absolutely have to.

Any input would be appreciated!

^^ since you don't have an STi... no need to worry about rewiring the whole car. All 02-05 USDM WRX are pretty much 95% plug and play with the ej207. The JDM engine harness will plug into your existing bulkhead harness, plus you add run an additional harness (i.e. IA performance) from the bulkhead to the new ECU, for AVCS to be functional. That's pretty much it according to my understanding.

Hoping this is correct, in which case my life just got much easier and I just got much happier

I should preface and say that I have had a version 8 engine/ECU running in my car with zero issues for a few years now, including the IA Performance AVCS wiring.

However, to add some complication to things, how many of you have looked very closely at the wiring for the V8 ECU into the 02 chassis? Specifically the venting/evap system. The 2002 WRX diagrams show a fuel temperature sensor, a pressure control solenoid valve, a drain valve, and a fuel tank pressure sensor all interfacing with the ECU in one way or another. The 2002 STi diagrams do not show these items, nor do the "version 8" diagrams I have seen.

My question becomes, if the version 8 ECU doesn't do anything on these wires, how do those items function on the 02 chassis? Obviously not all are needed, but it seems people have had complaints of not being able to fill their gas tanks when some of these items were malfunctioning. Again, one would think if the JDM ECU isn't doing anything with these items, then we should see issues with these items, correct?

So, does anyone know how/why it still works even though the diagrams say it shouldn't?

~T.J.

Yes, I have looked at these things and at how the evap system functions.

I am looking into the resistance that the fuel temp sensor provides, to see whether it is within the range of what a gauge would read, btw.

The system has two functions.
There is a drain valve which drains the charcoal canister and a pressure control solenoid valve, which additionally regulates the vapor pressure in the tank.
One of the ways these work is for one to be closed while the other is opened, to drain the canister, or to intake fresh air into the canister.

But even with both of these inoperative, there is a third line that takes vapors directly into the engine. This line is controlled by the purge control solenoid valve. This can be driven to a duty cycle that compensates for the inoperative status of the previous two components.
The JDM only uses the purge control solenoid valve, and my theory is that it's duty cycle already is setup to not allow high pressures in the tank, it controls the pressures in the tank already.
So my only concern is towards the charcoal canister eventually filling..
But then again, once a year, I have the USDM ECU running this for a while and it has plenty of time to discharge the canister.

In sum, there is no problem with the evaporation system due to the swap...
