A Front-Mount for the 2015 STi, Part 4: Final Prototype Fitting

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. [caption … Continue Reading ››

A Front-Mount for the 2015 STI, Part 3: Hot-Side Intercooler Pipe Fabrication

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. 2015 … <a href=Continue Reading ››

A Front-Mount for the 2015 STI, Part 2: Cold-Side Intercooler Pipe Fabrication

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.

The cold-side pipe is a great place to start because we are able to use a portion of … Continue Reading ››

2008-2014 Subaru WRX aluminum overflow tank pre-sale!

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 … Continue Reading ››

Dropping Intake Temps. 2015 STI FMIC R&D, Part 1: Core Fitment and Piping Plans

We’ve given the 2015 WRX quite a bit of love, mostly due to the introduction of the FA20DIT within the new chassis. Our team developed a ton of awesome components: a downpipe, an intake system, a couple different intercooler options, and various other neat parts. With our WRX projects mostly wrapped up, it’s time to turn our attention towards the STi. It still has an EJ engine under the hood, but it is mated to a new chassis that many are taking advantage of in various forms of competitive racing. So far we have developed an intake and a cat-back exhaust … Continue Reading ››
