After evaluating the design of our first prototype and performing some additional research regarding customer needs, we were prepared to fabricate a second prototype. As noted toward the end of our last post, we would be relocating our catch can for easier servicing, and we would also be designing a new catch can lid to accommodate the larger ports for the N54 CCV system.

BMW 335i test vehicle

The BMW N54 is a fantastic engine that produces great power in stock form and responds very well to basic modifications such as exhaust and ECU tuning. However, if you do not stay on top of servicing your BMW, maintenance and repair bills can certainly cast a shadow on 135i or 335i ownership. One of the primary challenges is dealing with valve buildups caused by oil entering the intake tract. Because the N54 is a direct injection engine, it does not benefit from the valve cleaning properties

What does one do with a blown Subaru EJ20? We asked this question on one of our social media outlets and had a ton of responses. This included a coffee table, flower pot, speaker system, stove, and even a boat anchor. After spinning a few rod bearings during some dyno testing (this WRX led a pretty rough life), we decided it was time to get creative with the remains. With an upcoming open-house event, we were determined to turn this grimy, beaten engine into a display unit for our Subaru product line.

With little time before the event, we set one of our engineers to the task of disassembling and refinishing this filthy engine. Our goal was to have a mobile display unit that could be used as a great conversation starter at events we attend. The entirety of our product line would be used to provide a neat glance at what we offer for the Subaru WRX/STI. Check out the build process below!

After a few hours in the shop, the engine was finally out and ready for disassembly.

Mishmoto Subaru WRX STi Performance Top-Mount Intercooler Kit

Testing day! After a long ride through development and design, it was finally time to see the fruits of our labor. Before strapping the STI to the dynamometer, we needed to prepare the coolers for testing. This included drilling and tapping the coolers for our temperature and pressure sensors at both the inlet tank and outlet tank.

Check out a few preparation shots of our stock cooler!

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
