BRZ/FR-S Black Fan Shroud Pre-Sale

With every revolution of our planet around the sun, things change. Change can be minute or monumental; previously unimaginable trends surface, while established empires fall. Fresh movements are founded, archaic ideas become obsolete - existing products are refreshed, old products are pulled from the shelves (but sometimes *thankfully* added back on - I'm hungry and envisioning a bowl of French Toast Crunch™). Be it little or large, history progresses, and it remains ceaselessly amazing to me to see how much of a difference even a subtle change often makes.

Just about a year ago, Mishimoto released our plug-n-play fan shroud kit for the then-Scion FR-S and Subaru BRZ. This fan shroud has been extremely popular

I have been a big fan of Subaru vehicles for a substantial part of my life, and I have lots of experience with WRXs, but the BRZ (and FR-S) is still very new to me. Not too long ago, one of our engineers had his 2013 Subaru BRZ out in the parking lot, and I asked him to pop the hood so that I might check out the power plant. Have you ever seen an old episode of Scooby-Doo when Shaggy opens a door and jumps about a mile in the air, screaming, having revealed the spooky ghost residing therein? Well, you can call me Shaggy, and here is the ghost:

Like, zoinks! Look at all that hideous white plastic - nobody wants a haunted Toyobaru, but how on earth would one solve this problem? Who ya gonna call?

Putting together our final prototype was a bit easier for this project compared to other front-mount intercooler (FMIC) kits our team has developed. As mentioned in previous segments, we used the crash beam and intercooler from our 2015 WRX kit. Now we've worked up some functional prototype piping for a final test fit.

First, let's take a quick look at each portion of the kit.

Intercooler and Crash Beam

The intercooler core is the key component in any intercooler kit. This core has provided significant air temperature drops during our testing on the WRX, and we expect the same results with the STi.

With our cold-side piping complete, it was time to focus on the hot side. This portion of the piping system would require a bit more attention, mainly because we were unable to scavenge any existing pipes from our WRX/STI front-mount intercooler kits (as we did with the cold side). Let's get to it!

Piping Fabrication

The hot-side piping will route from the turbocharger compressor outlet, around the driver side of the engine bay, and into the front bumper area to attach to the intercooler.

Here is a look at the turbocharger connection point.

A coupler attaches the pipe to the turbocharger.

Our first segment of this STI intercooler project involved the test fitting of our WRX crash beam and intercooler core. We were able to verify fitment of both pieces, which allowed our team to move on to piping fabrication. We are starting this kit with the cold-side pipe, which we've decided to place this on the passenger side of the engine bay to reduce the piping length as much as possible. Following this strategy should help reduce lag seen by the driver.

Pipe Fabrication

The cold-side pipe is a great place to start because we are able to use a portion of one of our existing kits. Because the 2015 model shares the EJ from the 2008+, we will be reusing the pipe that attaches to the throttle body and incorporates the BPV (bypass valve).

We last left you with some details of our initial design and a hint of an upcoming pre-sale for this overflow tank. Unfortunately, since that initial test fit we hit a few snags in the design process. Our goal with this product is to provide compatible fitment with all our other 2008+ WRX and STi components. This required numerous stages of test fitting, one of which revealed an issue. With our larger 3-row X-Line aluminum radiator installed, our sight tube on this expansion tank design ended up too close to the belt drive system on our Subaru.

We decided a revision was necessary. Although the two components were not physically touching, the clearances were just too tight for our comfort. Luckily, our team had an

The progress on our intake system is coming along nicely for this Forester XT. We have created a pipe that will fit well with our airbox design and filter selection. Remember, our pipe is within the acceptable pipe diameter to run this system with a stock tune.

The Fabricated Prototype

Below are some shots of the system we plan to put on an FXT for testing. The routing for this tube will follow a more direct path from filter to turbo. This is especially helpful for when the car is sitting at idle with ambient air around the box. With a shorter pipe distance, it will take less time for fresher, cooler air to get to the engine upon acceleration over stock. Check out images of the initial design below!
