Mishimoto BMW E30/E36 X-Line Performance Aluminum Radiator

Mishimoto is well known for providing innovative products for vehicles new and old. Our last few months have been dedicated to product development for the new 2015 Subaru WRX, which features a vast amount of changes from the previous generation. Along with these projects, we decided to go back to an older chassis and develop a brand new product for the E30/E36 BMW. We are huge BMW enthusiasts here, myself included, and we have found a gap in the radiator options for the late model E30 and E36 models. We have had great success with our current performance aluminum radiator for the E36. Our current offering is a perfect option for those who need an upgrade in the reliability department. The factory radiator is extremely prone

Time to see if this cooler can make a significant impact on fluid temperatures. As before, we borrowed a test fit vehicle from the folks over at Open Road Tuning. Once we had the car on the lift, we removed the factory cooler lines and spliced our temperature sensors into the stock lines so we could collect inlet and outlet fluid temperatures.

Temperature sensors installed

Mishimoto Subaru WRX Oil Cooler Kit

After releasing our most recent direct-fit oil cooler kit for the 2015 Subaru WRX, questions from our fan base and online communities began to fill our inboxes. Our kit included all necessary components for installation and placed a large 19-row oil cooler in the front grille area. We saw huge gains in cooling performance for this particular setup, with decreases of over 25°F. This project was extremely successful and we anticipated that our customers would be very pleased with the performance. The primary concern with a portion of enthusiasts was low fluid temperatures. This kit was designed with a vehicle-specific oil sandwich plate that sat on top of the factory oil cooler/warmer.

This was a truly unique design, however the one feature this component lacked was an

Our team now had a functioning oil line adapter to convert from the stock oil filter housing to -AN fittings. Now we would be able to move forward with designing the actual heat exchanger for our kit. We reached out to a few of our local friends and sourced this Oxford green example!

Test vehicle on lift

Our friend Andrew at Open Road Tuning was kind enough to loan his vehicle for a week of development! First we tore off the stock cooler to get a look at what kind of space we had to work with.

The BMW S54 won the "International Engine of the Year" award at its inception in 2001 and was consistently on "Ward's 10 Best Engines" list for four years. It's hard to argue against the E46, an 8,000 rpm, 3.2L straight-6 producing over 330 hp and 260 ft-lb of torque, with a competent chassis, an exhaust note that straightens the neck hair of all within earshot, and a body styling that is unmatched in uniqueness. Although my opinion is slightly skewed, being a fan of most BMW products, many would agree that the E46 was a fantastic vehicle for the street and even better for the track. E46 M3 pricing has trickled downward over the past few years, meaning that even those on a tighter budget can find their way into the cockpit of one of BMW's finest. We are seeing these vehicles at track

Time to start designing brackets! After a quick recap of the project goals, our creative engineering team began brainstorming. First, they selected a location for the catch can on the PCV valve side. It would need body mounting points for the can bracket, and preferably a short route for the hose so as not to complicate the engine bay. Our goal is a clean installation that appears stock-like, not a medusa of hoses routed about the engine bay.

The PCV valve on the 2015 WRX is located under the intercooler toward the rear of the engine block. You can see it in the image below, taken during a later stage of development of this kit.

If you follow our engineering blog or are involved with any of our social media outlets, you should be well aware of the new baffled oil catch can we recently released. This new product features a much smaller footprint compared to our existing catch can, allowing for fitment in tighter engine bays.

While developing this catch can, we wondered about using it in direct-fit kits for popular vehicles. For most drivers, a catch can is a DIY project requiring only the routing of hoses and fabrication of brackets for mounting the can. Installing a DIY setup that appears like it was made for the vehicle can be quite a challenge. This is where we come in, to take the guesswork out of a catch can installation. We are planning to provide mounting brackets, hardware,
