Here are hi-res pictures of the BMW F80 M3 and F82 M4 S55 engine out of the car
It is always nice to get good shots of a motor that show off the pulleys, accessories, intercooler, etc. The S55 engine from the F80 M3 and F82 M4 has been with us for some time now and we will likely see more of these getting pulled and built over the years especially as cars come off the warranty period.
The main question of course with the S55 motor is the crank hub
and ways to address it spinning as power is added. There is no definitive solution yet that BimmerBoost is aware of.
Enjoy the pics.
