The E34 BMW 520i was my first car. That’s why I feel a shiver down my spine each time I write a story about this model. And today is that special moment, when a modified item showed its face on the internet. And it’s an impressive one: it has a V12 engine coming from an E31 850CSi.
Well, the original M5 wasn’t a common car from the first time. Even by today’s standards, its 335 hp and 400 Nm of torque are pretty impressive. They come from the charismatic S38, 6 cylinder in-line engine, displacing 3.8 liter. But, obviously, the power didn’t impress this item’s owner.
Therefore, he opted for a more powerful powertrain. The impressive unit is a S70B56 V12 engine, which equipped the ultra-rare E31 850CSi. It was built in just over 1500 units, and it served as base for the thrilling S70/2, which equipped the McLaren F1 supercar.
The V12, has a 5.6 liter displacement and develops 380 hp and 550 Nm of torque, values that transform the E34 in a 5 seats supercar. More, the engine was further modified for a good 420 hp and has been matted to a 6 speed manual Getrag 560G transmission. This is commanded by a UUC short shifter, and sends the power to the ground via a Quaife limited slip differential.It breathes out through a Eisenman stainless exhaust.
We’re talking about a big amount of power here, so the brakes have also been replaced with a UUC set, consisting of a 14” pair of disc brakes in front and a 12.9” in the rear. A new suspension kit has been installed, to lower the ride. It consists of EDCIII self leveling shocks, HR springs, new sway bars and a strut tower brace.
The car is on sale for $16.500, which is a fair price, considering the level of modifications and its vintage image.
