MHI N20 Big Turbo - F22 228i, F30 328i, F32 428i, X3 28i, X4 28i



Mitsubishi Heavy Industries (MHI) Big Turbo for 7/2012+ BMW 228i/328i/428i/528i/X1/X3/X4 with N20 engines and electric wastegate. With minor modifications this can also work on early cars with pneumatic wastegate (see below). OEM-developed turbo upgrade, with input from BimmerWorld Racing Complete turbo + manifold + wastegate = easy bolt on! Cooler intake charge even with more boost Reduces strain on other systems Gain power without sacrificing turbo life Epic software tuning available to complete the upgrade - 400ft-lbs torque! You don't have to worry about that though! The N20 MHI Big Turbo is really a perfect upgrade for N20 engines on the street or track use. Turning up the boost with the stock turbo will quickly reveal its deficiencies. The stock turbo is already spinning fast and turning up the boost will over-speed the turbo, resulting in a lot more heat for not much more power. It's also not good for the life of the turbo. Heat is spread throughout the rest of the engine and accessories further straining the oil and cooling systems. The bigger turbo allows more boost with less effort and heat. We believe this is the ultimate direct fit turbo on the market! We've found this turbo makes noticeable torque and horsepower gains - 20% across the board - even on a stock car without more boost! How can you make more power with the same level of boost? Easy! You use a higher flow-rate turbo, which can handle a larger air mass at the same PSI. The result is a turbo that's less overworked, at a lower temperatures, moving a greater volume of air, and without taxing the internal components. If you are tuned for more boost (or are planning to), the effects of this turbo are even more dramatic. This is not a "rebuilt" turbo, or a Frankenstein creation using recycled parts, like what the competition sells. And you're not getting "half" of a turbo (like another popular tuner sells). You're not swapping the "guts" of your current stock turbo either. This is a 100% bolt-on replacement, complete with the manifold, integrated turbo, as well as a new electronic waste gate assembly. It comes as pictured, and is the most complete and ready-to-install N20 Big Turbo on the market - and from the OE manufacturer! Because the MHI Big Turbo is manufactured new, there is no core charge. The MHI N20 turbo is the same twin-scroll design as the original turbo so boost lag is minimized and low and mid-range torque does not suffer. It uses a 58mm 20T billet compressor wheel (2618-T6511) with MHI's newest generation blade design for improved aerodynamics. The compressor has 7 primary blades and 7 splitter blades and is tested for up to 32 PSI boost with a max flow rate of 40 lb per minute. MHI went with a machined billet wheel instead of the stock cast piece for extra strength, lighter weight, and improved durability. The turbine has a 9 blade "TD04 " Inconel turbine wheel, with an input of 47mm and output diameter of 41.2mm. While the MHI turbo can be used as a true bolt-on replacement, it really shines with proper tuning. Epic Motorsports tuned our in-house street F30 328i and we offer the turbo + software tune in our Stage 5 packages (see below). The tuned N20 makes 340ft-lbs to the wheels at peak torque output - more than an E39 M5 V8! "This car is an absolute hammer!" - James Clay, founder and president. Fitment on cars with pneumatic wastegate (PWG): your original PWG and actuator arm must be transferred to the new turbo housing. The wastegate pot is a simple bolt on. The hole for the mounting pin on the PWG arm must be drilled out to 10mm. These are very simple modifications that should only take a few minutes to complete. Feel free to contact us with any questions.
