Ready for some interesting test results? After around 2,000 miles on a BRZ, this kit was ready to be inspected to see what kind of byproduct had accumulated in each can. The plan was to evaluate both systems to determine whether a single- or dual-can setup was necessary. If one of the lines did not collect any fluid, the need for a catch can would not be justified. So, we popped the hood and inspected the system to see if road abuse had a negative impact on the mounting brackets or lines.

All our components held up just fine, as expected. All mounting brackets were still securely positioned, and the lines appeared to be in great shape (no rubbing). First, we popped off the can spliced into the PCV line of the BRZ. These images also show that we have provided plenty of room below the can

Second Prototype Bracket Fabrication

Now that we had our catch can ready to go, it was time to select mounting locations, and fabricate the mounting brackets. First, we will start with the PCV line we initially targeted with the large catch can we had. Check out some initial mock-up shots!

Compared to the previous mounting point, we have moved this catch can to a more centralized position. We are no longer using the battery tie-down as a mounting point. This provides a cleaner install, and it also provides space for the brake booster/master on RHD vehicles. The lines shown in the image are purely for mockup and routing purposes.

We will likely offer these lines in our standard three colors; black, blue and red. We also use silicone lines for all of our direct fit kits. Silicone

Welcome back to the build of our BRZ/FR-S catch can system! After laying out the guidelines from the last post, we were ready to get some hands on the vehicle and start piecing together some can brackets. Before jumping into product design, we will quickly cover the unique injection system featured on the BRZ/FR-S FA20 engine.

FA20 Fuel Injection

As many of you are aware, the FA20 is not what you could consider a traditional direct-injection engine. This specific system is identified as D-4S on the top of your intake manifold. The system utilizes four direct injectors and four port injectors for appropriate fueling. Yes, your 4-cylinder has eight injectors! The direct injection portion of the system is key for an efficient combustion process, and it allows for a high compression ratio without exaggerating the fear of detonation. Adding

Why a Catch Can?

Catch cans are used only for turbocharged vehicles, right? This is a question we hear all the time. Yes, a turbocharged vehicle is more likely to produce greater blow-by, resulting in a more prominent collection of debris in the intake manifold and tract. That being said, any engine is certainly susceptible to oil and fuel collection due to the use of PCV and CCV systems, which improve engine efficiency and provide cleaner emissions. Mishimoto has been working on developing several direct-fit oil catch-can systems for a variety of vehicles. So far we have completed kits for the Subaru WRX/STI for 2008-2015. We have also experimented with a kit for the BMW E90, a vehicle that suffers from intake valve buildups that require frequent servicing. With the arrival of our 2015 Ford Mustang EcoBoost test vehicle, we also began
