BMW Wagon With Maserati V8 Engine Laughs At Your Silly LS Swap

BMW pledges to produce the ultimate driving machine. But after they have changed hands, those machines may serve as the basis for an enthusiast's modified, personal ultimate driving machine, which could mean swapping in a more potent BMW plant or even performing an LS swap. One custom build we haven't seen before is a wild Maserati swap that showed up on Cars & Bids.

Meet The Most Modified BMW 328xi Wagon Conceivable

The base vehicle for the build is a BMW 328xi wagon. It has most of the bodywork and the badging. That's about all it retains from the stock vehicle. The main swap performed is the engine. The owner swapped in a Maserati 4.7-liter V8. That engine is known as the F136, with "F" standing for Ferrari, the brand that developed it with Maserati. The F136 was Ferrari's last naturally-aspirated V8.

According to the listing, the engine put out 433 horsepower and 361 pound-feet of torque in stock form. However, the seller believes that the output may be higher with its custom tuning through an ECUMaster standalone ECU. The owner performed a transmission swap with a Nissan CD009 six-speed manual. The owner also converted the 328xi from all-wheel drive to rear-wheel drive.

The owner then added several parts from the E9X M3, including a full catless exhaust system, front brake calipers and rotors, a front bumper, fenders, side skirts, core support, carbon crash bar, and mirrors. The car also has mods such as a Seibon Carbon Fiber hood (with a Ferrari badge), an aftermarket front lip, a custom rear diffuser, and Recaro Sportster front seats. The owner even sourced a factory M Performance Alcantara armrest.

The seller notes a few issues for the buyer to address. The new owner will need to code the FRM and CAS modules, and the seller notes that the 4x4, brake, and ABS warning lights are activated. The 18-year-old wagon is also not in perfect condition. There's a scratch on the passenger-side front and rear doors, a ding on the passenger-side rear quarter panel, a cracked reflector on the driver's side, and "stains on the rear seats."

Was This BMW Unicorn A Steal At $28,050?

The highest bidder landed this 2007 BMW 328xi for just $28,050 after the seller lowered the reserve. One could kind of justify that as a great deal. The $28,050 price tag doesn't cover the more than $28,050 worth of work that went into creating this car. And a wagon with a Ferrari-built V8, a six-speed manual transmission, and potentially well north of 400 horsepower isn't something one can just buy for any price, let alone less than $30,000.

On the other hand, LS swaps are popular in these builds because GM V8 engines are plentiful, reliable, affordable, and easy to maintain. One would seldom, if ever, use one of those words to describe an aging Maserati powerplant, especially one working with a myriad of aftermarket components not originally designed to work with it. And the electrical gremlins to sort out here sound formidable.
