Mishmoto Subaru WRX STi Performance Top-Mount Intercooler Kit

Did you think we would just develop a top-mount intercooler (TMIC) for the GD WRX and leave out the STI? No way! At around the same time we began development on the WRX, we picked up a new shop vehicle, a 2010 STI. When a new vehicle makes its way into shop service, we need to be sure it accelerates and handles properly. The STI passed our checkup. We then set out to determine what products we wanted to develop first. We already had a few items on the market, including a performance aluminum radiator and a silicone radiator hose kit. Our first target had been a direct-fit oil cooler that proved to be extremely successful, providing a 20°F drop in oil temperatures during our testing. Next we created a plug-n-play fan shroud with dual 12" electric

The most obvious thing to do with your brand new WRX is to take it to the track immediately after leaving the dealership. Fortunately, the WRX is a rather competitive package right out of the box. Our initial driving impressions were very positive, and we have no doubt that this vehicle is going to make a big impact on the enthusiast world. We monitored fluid temperatures at stock power levels during normal driving conditions and found that everything seems to be in spec. We are assuming a majority of these vehicles will not remain at stock power levels for

Testing time! Well " almost. We had a few quick testing details to sort out and some preparations before we actually began. First, we needed to drill and tap the stock intercooler as well as the Mishimoto prototypes so we could install our pressure/temperature sensors. Additionally, we decided to create a shroud for our TMIC fan to ensure that all cores would receive appropriate airflow on the dynamometer.

Tapping the intercoolers for sensors is a relatively straightforward process. We drilled into both end tanks and then tapped them

As I am sure you are aware, we have been working diligently to develop innovative components for the new 2015 Subaru WRX. To continue our video series regarding the new model, we have captured some of the new products in various stages.

Check out these videos featuring our in-house Subaru expert, Jason, as he provides an inside look at products we already have on the market, as well as two unique products we are currently working on.

Last time, we left you with a teaser of the rendering for our prototype of the top-mount intercooler (TMIC). Since then Dan has been hard at work refining his design. Our team worked up some CFD analyses of both the stock intercooler and the Mishimoto prototype. And, we also worked up a few functioning prototypes so we could begin real-world product testing. This project is moving quickly and our team is rather excited to see the outcome. Take a look at the finalized rendering of our cooler below!

Nothing sets off a Subaru engine bay like a nice beefy top-mount intercooler. Not only does a big TMIC look great, but it is also instrumental for keeping AITs low and your EJ happy. For those seeking low AITs on a stock to mild build, an efficient top-mount setup is the way to go to avoid inheriting the pressure drop and lag from a front-mount intercooler. Not only this, but the TMIC prevents any road (or off-road) debris from damaging your heat exchanger. This is key for those who are involved in any rally, off-road, or rallycross events.

If you keep up with any of our social media outlets, you are likely aware that Mishimoto has been working to develop a TMIC for the 2008-2014 WRX. We are very active within the Subaru enthusiast community,

Mishimoto Silicone Induction Hose For Subaru BRZ / Scion FR-S

Thanks for returning for the second portion of this build! As mentioned in the previous post, our team was prepared to conduct extensive testing on this induction hose. Our main goal with testing was to determine the particular combination of components that would provide the most power output. Power output collection would be via our Dynojet. Each combination of components received an average output based on three consecutive runs all completed on the same day with essentially similar conditions. The variations of testing are below.

1. Resonator and noise amplifier both installed
2. Resonator plugged with noise amplifier installed
3. Resonator attached with noise amplifier disabled
4. Resonator and noise amplifier

Mishimoto Silicone Induction Hose For Subaru BRZ / Scion FR-S

The BRZ/FR-S is one of the hottest cars to hit the track in the past few years, and the Mishimoto engineers decided to do what they do best: cool it down. Naturally, we would be developing a performance aluminum radiator and silicone hose kit. Additionally we ended up with a killer direct-fit oil cooler kit, some very slick oil caps, and a low-temperature thermostat. As you may have seen in our other build-log, we are also developing a performance cold air intake, which we estimate will provide a nice increase in power and really bring out some of the engine tones being baffled by the factory system. This article is not about the full intake system we have planned. It's about the silicone induction hose we developed in the mix with all the products
