Subaru WRX Baffled Oil Catch Can System

If you follow our engineering blog or are involved with any of our social media outlets, you should be well aware of the new baffled oil catch can we recently released. This new product features a much smaller footprint compared to our existing catch can, allowing for fitment in tighter engine bays.

While developing this catch can, we wondered about using it in direct-fit kits for popular vehicles. For most drivers, a catch can is a DIY project requiring only the routing of hoses and fabrication of brackets for mounting the can. Installing a DIY setup that appears like it was made for the vehicle can be quite a challenge. This is where we come in, to take the guesswork out of a catch can installation. We are planning to provide mounting brackets, hardware,

Now that we had our first prototype unit in, it was time to evaluate fitment and determine if any changes were necessary when compared to the stock unit. First, we swapped the shrouds to see if any fitment issues existed because of the added size of the Mishimoto unit.

Mishimoto Subaru WRX CVT Transmission Cooler

For our third prototype unit for the CVT cooler, we decided to take a more traditional approach. We would place the cooler in a location that would guarantee airflow. The main concern was fitting our large 19-row cooler in a position that would not leave any space for other aftermarket components. First, we mocked-up the cooler and developed some basic brackets that would place the cooler in an angled position behind the upper grille area. Check out a few shots of the mounted cooler!

The new 2015 WRX is a great toy for both daily use and as a weekend track warrior. The introduction of the FA20DIT into the WRX chassis has been well received, and from the reviews thus far, Subaru has done a great job with the new model. Although some might disagree with the styling, overall the car handles and performs very well. As for value, the 2015 model is a pretty decent bang for your buck. For those looking to track their brand new vehicle, a few bolt-on modifications will raise power levels significantly. A simple intake and tune will raise power to 275+ whp, which is a huge increase over the 210 whp we saw from a completely stock vehicle. Reaching 300 whp is potentially obtainable with a few additional exhaust modifications. We are

After we witnessed reasonable performance gains with our first prototype, we decided to evaluate what we liked and didn't like with the design.

Pros

• Short line lengths
• Efficient cooling
• Compact design and packaging

Cons

• Did not achieve the temperature decreases we wanted to see
• Requires wiring of the electric fan
• Airflow was not as sufficient as it could be

This first design was efficient but not ideal for what we wanted out of the project. To obtain the desired cooling benefits, the addition of an electric fan was necessary. However, the fan would add complexity and wiring to the product, which we would like to avoid. So we hit the drawing

Welcome back! The quest for low transmission fluid temperatures continues. Once we developed our goals and plan of action for this project, our engineering team went to work, grinding, welding, bending, and cutting. Our first prototype design was quite unique. We mounted one of our 19-row, stacked-plate fluid coolers next to the liquid-to-liquid transfer unit. This is the same location as the turbocharger on the previous generation of EJ engines. Check out the beginning of the mock-up below!

What does one do with a blown Subaru EJ20? We asked this question on one of our social media outlets and had a ton of responses. This included a coffee table, flower pot, speaker system, stove, and even a boat anchor. After spinning a few rod bearings during some dyno testing (this WRX led a pretty rough life), we decided it was time to get creative with the remains. With an upcoming open-house event, we were determined to turn this grimy, beaten engine into a display unit for our Subaru product line.

With little time before the event, we set one of our engineers to the task of disassembling and refinishing this filthy engine. Our goal was to have a mobile display unit that could be used as a great conversation starter at events we attend. The entirety of our product line would be used to provide a neat glance at what we offer for the Subaru WRX/STI. Check out the build process below!

After a few hours in the shop, the engine was finally out and ready for disassembly.

Testing day! After a long ride through development and design, it was finally time to see the fruits of our labor. Before strapping the STI to the dynamometer, we needed to prepare the coolers for testing. This included drilling and tapping the coolers for our temperature and pressure sensors at both the inlet tank and outlet tank.
