Dinan's 35 years of BMW tuning and racing experience ensure that the engines will not only perform but also provide years of trouble free driving excitement. Much of the technology that has made Dinan's Grand-Am Daytona Prototype engines both competitive and reliable has carried over to the 4.2 Liter V-8 engine program for the street, ensuring that the engines produce incredible power along with race-proven durability. Equally impressive is the fact that all of this performance is available without sacrificing BMW-like drivability or the peace of mind that comes from matching new car warranty coverage for up to 4 years or 50,000 miles. If your vehicle is no longer under the BMW factory warranty, we will cover you new engine for 2 years and unlimited miles.
The engine is supplied as an assembled long-block, fully prepared to directly replace the stock engine without modification. Maximum performance is achieved when the engine is equipped with the optional High Flow Intake, High Flow Throttle Bodies, 16% underdrive pulley and Free Flow Mufflers. For those seeking to replace their tired M3 engine, without sacrificing civility, reliability or warranty coverage, the Dinan 4.2 Liter V-8 is the definitive solution.
