Awesome! Thanks for checking it out.

The PCV can with such hoses layout will be not easy to install on AT cars but manageble.

I'm curious to see if we do truly need both or if one will suffice once their testing is complete. I know two would make it easier but if I could add it later that would be ideal.

Luckily we actually have access to an automatic FR-S. We checked the located of the catch can, there should not be any fitment concerns with the can mounting location or the hose routing.

Exactly, this is the reasoning for our road testing. We want to ensure that both cans are necessary before launching this product. It may turn out that only one is truly necessary. We should have an update on this thread early next week with our results!

Thanks for following!

What the price point are you trying to hit?

As always, we will be offering the most value possible. At this time, our testing is not complete. We do not yet know if a single can or dual can setup will be necessary. We should have an update by the end of the week with some additional information!

Thanks for the interest.

any more updates besides the ones from last week? very interested in a dual can setup so long as it performs and looks decent.

We should have a development update, with testing results, early next week.

Thanks for the interest and patience!

The results are in! Check it out.

Mishimoto 2013+ Subaru BRZ / Scion FR-S Direct-Fit Baffled Oil Catch Can System, Part 4: Testing Results and Project Completion

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 to allow for easy removal of the base for fluid extraction.

Immediately we can see some evidence that this can is functioning. This last shot proves a few things for us. One, the baffle is working to provide a surface for the fluid to condense, and second, the PCV line is definitely passing some oil into the intake system of the BRZ. Take a look below at the can itself.


PCV catch can accumulation

You can see that a thin layer of oil coats the entire can, and a bit of fluid accumulated in the base. Although not a substantial amount of fluid (we saw quite a bit more with our EcoBoost kit), we still wouldn’t want this ending up in our intake.

Next we removed the breather-side catch can base and examined it for fluid. We found it interesting that this can was bone dry. It smelled of fuel/oil, but there was no evidence of even a thin film on the inside of the catch can. These results were almost identical to what we saw on our 2.3L Mustang kit (developed around the same timeframe as this one).

What does this mean? Well, first of all, we would not be selling a component that you don’t need, so our kit for the FRS/BR-Z will include a catch can for only the PCV system. However, there is a possibility that some highly modified vehicles might necessitate a second can for the breather system. Because we already designed this system, it would be easy to release an additional kit for modified vehicles. For now, we are confident that the single-can system is the right application for BRZ owners. With our testing complete, we could now begin mass production of our kit. Check out a drawing of the bracket to be included.

$175! Dooo eeeet man! I buy! AND I would love to have the breather side option because I am F.I. and have found blow by accumulation in the front as well. Please offer both!

[WRB5titch]

Count me IN for 175! +1 on the breather side option as well.
