It's hard to say which BMW is the best of all time. We're not going to say the E34 was the best 5 Series ever made (even though some fans might bring compelling arguments) but it was one of the cars that really made you feel alive.
The owner of this custom E34 decided the stock feeling of such a 5er wasn't enough so he decided to do some work on the engine. The stock M50 engine received some Wiseco pistons and eagle rods, an M52 crankshaft and a T4 76mm turbo.
The end result? Well, the owner claims that on a street tune with 93 octane fuel (with some meth) it managed to push out 686 WHP. That is enormous, especially from a M50 engine.
Looking at the video and hearing that amazing exhaust it's easy to see why some people would argue that the E34 was and still is the best 5 Series ever made. The bond created between you and the road through this magnificent car and the way it feels is just too hard to put in words.
