Dinan Strokes BMW M3's V8 to 4.6-liters and 527HP

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".

The decked-out Dinan M3 receives "new springs, front anti-swaybar, Carbon Fiber Front Strut Braces and Racing Rear Toe Links" while riding on relatively plain 19-inch one-piece wheels.

Now, what you've all been waiting for: it makes a naturally-aspirated 527 horsepower and 407 lb-ft of twist, and Dinan claims that it can crack 200 mph or 322 km/h. Damn.

Scroll down for their tech specs and a video.
