California-based Dinan has put out their biggest-ever take on the BMW M3. The Dinanized bimmer is called the S3-R, and in place of the original 4.0 liter V8 is an engine that's been bored and stroked to 4.6 liters.

Up top, breathing is heavier thanks to a "Carbon Fiber High Flow Intake and bored out High Flow Throttle Bodies"; down low Dinan fits a free-flowing exhaust system that also makes use of pieces labeled "HIGH FLOW".
