Porsche Boxster Engines Specs & Generations
The Porsche Boxster uses a range of flat-six engines (M96 and M97 series) depending on model year, with sizes from 2.5L to 3.4L. Early base models ran the 2.5L and 2.7L M96, while the Boxster S stepped up to a 3.2L unit producing roughly 250 horsepower — a popular swap target if you're hunting a Porsche Boxster 3.2 engine for sale. If your build year falls in the early 2000s, you're likely dealing with the 2003 Porsche Boxster engine 2.7 L 6 cylinder, a naturally aspirated flat-six still in steady demand among U.S. enthusiasts today.
What Engine Comes in a Porsche Boxster?
Unlike most sports cars, the Boxster mounts its boxer-style flat-six just ahead of the rear axle and behind the seats a true mid-engine layout. This placement lowers the car's center of gravity and sharpens handling, but it also means swaps require tighter clearance and are best left to a shop familiar with Porsche drivetrains and known IMS bearing concerns.
