In all honesty the car gets a hard pull once in a blue moon and after the first few cuts I've not pulled on it hard enough to cause any more. *knocks on wood*

But I'm picking up what you're putting down, no worries. So is the store located in the US or Canada? If it's US we're in trouble because border delays alone can ruin replacement part orders.

i figured it was just a way to distinguish guys who have those brakes. you know like bro-nies, and bro-gramers. you see each other on track days: "yo brembro! check out my fresh painted calipers!"

Default Project Domino: Short Shifter

We installed the Cobb short throw shifter the other day. The cool thing about the Cobb part vs the rest, is that both the throw and the height are adjustable.

If you want to see the details of how to install, you can check out Cobb's install instructions. Plus, there are probably 100s of YouTube videos as well.

The only odd thing that I would add is that they didn't include a fresh new bushing for the whole near the 'C', so I had to push out the old one an reuse it. It got a little mangled in the process. Also they didn't include any grease for the ball part, but I had some extra grease laying around from other parts.



Here is the old one with the cable removed.



The Cobb one in from the left side.



Here it is from the right side.



Also, some wiring progress has been made.

Hmmm I've never seen a short shifter that came with grease or the seal.. Your install notes are pretty much identical to all the installs I've seen, especially the 'scrounging grease from other parts' bit.

Reminds me that I need to get a good solid knob to swap for the WRX knob with it's mystery-rattle-bits?!

Oh another thing, it seems like the spring action of the reverse release knob has stopped working. Is this a common issue with the Cobb shifter?

Default Proyecto Domino: GrimmSpeed Adir Oil Separator Review

I got around to installing the GrimmSpeed air oil separator. We used this same piece on our last project car as well. I like it because it doesn't take up a lot of space and uses the oil filler to return the oil back into the system. I also like it because it didn't prevent our last project car from making power. It seems to "work" ... although ... I haven't taken apart the intake of the other project car recently, so I can't be 100% certain their isn't oil build up. Aside from the space constraints, I would probably just recommend the Cosworth part instead, but they are harder to fit if you are rotated, etc.

So, you can see here that it replaces the oil filler cap. This actually makes it hard to add oil unless you use a funnel. I think that limitation should be noted as a con.



Here it is hooked up to the left side of the motor. The two sides of the front vale cover ports are hooked to this line. It is connected to the right port of the AOS. Note: GrimmSpeed did not include this tee. Consider this another con. If you have a stock top mount, then the y pipe on top would be used instead. Really? Who has a stock top mount with the stock y pipe such that they don't need a tee? GrimmSpeed maybe saved a buck or two in BOM.



Here it is hooked up to the crank case. This is what is connected to the left port.



The front port here on the right valve cover is what is connected to the tee. It is hard to see in the pic, but the place where the crank case used to vent to the intake is capped off.



The center port on the AOS connects back to the intake like this.



GrimmSpeed was super generous and provided an extra foot or two of heater hose. Thanks guys. I would have preferred you provided the tee connector I had to go buy.



I also repaired he hose on the far right. Mine case cut for some reason. Also just using 1/2" heater hose seemed to collapse, so I bought the real OEM part to repair it.

The new CXRacing radiator is in. It was made for a GD chassis, but we talked about the differences before in a previous post. Here is a picture on my GD chassised 2005 Saab 92x AKA Saabaru. There is actually 5" or so more space between the radiator and the engine in the GD as compared to a GC8.



Note the lack of space in Domino. Also the version 8 STI twin scroll header doesn't make it easier.



Since there isn't a lot of space, and this radiator is about 0.5" thicker than stock, we had to be creative. First we ditched the awesome aluminum radiator shroud that we had bought for the project because it added 0.5-1" more thickness, and positioned the right fan right where the exhaust manifold is. We put the fans directly on the core without the shroud using the included special zip ties included for this purpose. We positioned the fans all the way to the top, and that was just enough to provide sufficient clearance.



Both fans affixed.



What the zip ties look like on the front of the radiator.



As you can see, there still isn't a lot of space.



Another angle.



We had to drill holes through the beam to get the brackets to work with the GD radiator. We use the Perrin radiator mount..because it was the cheapest at wholesale . We had to cut of a chunk of it to get it to fit the CXRacing radiator. The next mod will be the Perrin logo delete sharpie mod.



Here is the hose installed.



The bottom radiator hose.

Default R160 + 400 ft*lbs = Complete Failure

Ever wonder why we swapped out the whole drive train in Domino? The stock RS 5-speed drive line was mechanically working just fine. The reason is because we are targeting 400 hp and 400 ft*lbs at the wheels. The STI 6-speed + R180, and the 5x114 axles we are using can reliably run that kind of power without drama. 5-speeds cannot.

One of our other cars has been running with a stock 5-speed drive line with 460 hp and 400 ft*lbs at the crank. Note: it was tuned *down* to 400 ft*lbs to improve the longevity of the drive line.

Default Project Domino: Intake Plumbing

There are a lot of advantages of the boxer engine layout: it has a lower center of gravity, it is intrinsically counter balanced, it is compact, etc. One of the downfalls of the turbocharged Subaru boxer motor is all the extra plumbing. The ports on the left head are as far away as they can be from the right head. It forces the manifolds runners to be long. For the EJ motors, the exhaust path is made to be a few feet long from the exhaust ports on the motor to the turbo. But, the place the turbo fairly close to the factory top mount intercooler (TMIC), so at least that plumbing is minimized to a foot or so. The FA20A DIT engine has super short exhaust runners before the turbo. It still has a TMIC, but it is better to have a shorter exhaust path to maintain the energy than have a shorter boost path.

Here is the turbo off of the new 2015 WRX FA20 DIT motor:



There are a few problems with the TMIC. The first one is heat soak since it is right next to the turbo and engine. The second one is size; there is only so much space to put a larger TMIC. Also, you are limited by the scoop on the hood, and how well the splitter works getting the passing air through the intercooler.

A more optimal location is to have your intercooler on the front of the car. Many factory turbocharged cars have front mounted intercoolers (FMIC). That is where most cold air hits the car as you drive. It won't get heat soaked from the engine and turbo. Also, there is more space to put a very large intercooler.

At SEMA last year, I asked an engineer from a German intercooler company when is the intercooler too big. He said there isn't "too big" for intercoolers. That is mostly correct, but kind of an over simplification; however, the point of this post isn't to deep dive into intercoolers.

Anyway, a FMIC on a Subaru is useful because of the previously mentioned reasons. The down side is that it adds feet of extra piping which can increase turbo lag among other things.

We decided to run a FMIC on project Domino. There aren't exactly kits on the market that are made for a GM chassis and a GD motor, so we had to make our own.

Here is all of the extra piping that needed to be added for the FMIC setup.



Check out the size of the core! It is something like 32" x 12" x 3". It is a little ridiculous, but it is actually the perfect size to fill the void in the bumper cover. Plus, I have the German engineer on my side that it isn't too big. We drilled some holes on the lightened bumper beam to mount it, and the bottom part of the bumper beam had to be cut out a little for the IC pipes to make it through. There is no way that this would fit with the factory USDM bumper beam. FYI, the JDM bumper beam doesn't have the lower part that I had to cut off.



Since we added an new 32" x 12" x 3" volume before the radiator, the bumper cover had to be trimmed. How much? About 4".



Here are some of the leftovers to give you an idea how much had to be cut away:



All cut out:



This is what it looks like mounted up. There is literally no extra space in the bumper cover with this intercooler.



Additionally, we have been making good progress with the wiring. The harness is all together and mounted. We are in the testing phase right now before we plug the ECU in.

Default Project Domino Small Update

Project Domino has been on the back burner for a little while, but we have been making a little progress.

The wiring is mostly done. Today we got the DCCD all wired up. The wires got damaged on the transmission, but we got them all cleaned up.

Power steering lines are hooked up to the rack, and the bumper cover is all set.

did you test-fit the FA20 DIT turbo, to the EJ207?

I think that the scavenger pump is not in the assembly. How much is that turbo-manifold assembly anyway?

I don't think the FA manifold is compatible with the EJ motor. In any case, we have other products we are developing with those FA parts.

Major milestone, we've managed to have the motor running. What this means is the wiring is now all sorted out, and we managed to hook up the last fuel lines. We only ran the motor for a few seconds because that is about all that is hooked up. With that said, we actually don't have a lot of major things to do to have Domino rolling around on her own power.

Check out the video.

Things left before Domino is a working car:
  • Cooling system
    • Remaining coolant lines need to be hooked up
    • Needs to be filled
  • Power steering
    • Lines need to be connected to the pump
    • Reservoir needs to be secured
    • Filled up
  • Add gear oil to transmission and diff
  • Intake pipes
    • Last two IC pipes need to be hooked up
    • BOV installed
    • Intake installed
  • Chassis bolts need to be double checked against correct torque specs. They should already be there, but we'll double check.
  • Install downpipe and catback
  • Reinstall interior
  • Relocate battery to trunk
  • Reattach a few body components

That might be enough to take Domino to get some licence plates. Obviously there will be a lot more to do after that, but our next goal is to get her registered.

We've made a lot of progress since the last post thanks to the help of Teryn, our super tech. Domino now has plates, and driving around.

It has been a little while since I last posted anything about Project Domino, but rest assured, we have been making steady progress.

For an update, the wiring is all but buttoned up. It is all completed except the DCCDPro. All of the sensors, etc. are connected. Everything is correctly grounded with my "JDM yo" grounding kit.

All of the water lines and power steering lines are hooked up.







The interior wiring. Obviously the interior needs to be put back together fully.



All suspension and chassis component's torque specs have been double checked and verified on Domino. It is not sexy, but it is good to know the rear diff will not come off while racing.

Yesterday was a big day for Domino. She was driving under her own power. It almost brings a tear to one's eye. Look at her slowly burn off years of old oil and fluids. If my neighbors could see this, they would understand why the flowerbeds look like crap!

One of the first things that was lacking, was a good battery. The old lead acid one, like maybe 10 years old, and long dead. The dirty yellow top is also mostly dead and not up to the task. You may have noticed I went with the Optima D51R this time instead of the normal sized battery. It actually has plenty of cranking power, and weighs 10 lbs less. I also am not planning to have a banging stereo in this car.



Ultimately the battery will be mounted in the trunk, probably in this spot, but standing up.



The green plug in the center is the flashing mode jumper from the 03 WRX harness. As you may guess, it needs to be in test mode for the Tactrix cable, plugged into the OBDII, to read and write the ECU ROM. We actually had a few problems getting it working in the first place. Brydon actually had a bug in the write up, and a few of the pins were swapped in the OBDII connector. Once we fixed that, the ECUFash tool was working perfectly.

Still pending on the harness, are the AVCS solenoids are throwing faults, so maybe there is a nother bug? Also the O2 sensor is reading 0. Oh well, we are almost there.



Another large gap was the exhaust system. Luckily I had an extra turbo back laying around from my other car that I could cut up and make work. I also had a Kinugawa twin scroll bell-mouth elbow that they don't sell anymore. I had to cut the single scroll elbow that was on there off, and swapped it for the Kinuagawa one. Then the midpipe was shortened by like 1.5", and then the transmission brackets were adjusted. Voila, I now have a custom turbo back that is compatible with a GM chassis and a JDM EJ207 twin scroll motor.

The other part of the story is that it was really hard to find a place that would work on a catless exhaust. Even when I got there they didn't want to do the work. Eventually I convinced them, doing the work, but reinstalling the OEM catted downpipe so that I would leave complaint with emissions. They still charged me for installing a full turbo back all the same. Then I just spend a few hours putting it back on later that night.









Next up, suspension setup.

From previous experience, I'd say that looks more like the LH bearing failed. It really hurts when that whipes out a trans with a PPG gearset in it
