Deciding upon an engine for my car, Rusty, was far from a simple task. I’d like to suggest that all along, I knew exactly what I wanted, but that couldn’t be further from the truth. In fact, several engines came to the shop, and then left on truck beds… An S62, an M106, and I even came close to pulling the trigger on an S85 V10 before I finally settled on what I felt was most true to form: the truly unique, and truly “BMW” S38 inline-six.
In the world of the BMW aftermarket, a hierarchy of names exists to separate the bad from the good, and the good from the great. At the top of the list, you’ll rarely find that the likes of AC Schnitzer, Alpina, and Hartge are ever disputed. Be it their racing heritage, or their “mad scientist” approach of cramming oversized engines into undersized cars, they’ve earned their place and staying power.
