Steve's Evil Bimmer S54 Supercharged M Coupe
Steve's 'Evil Bimmer'
One killer S54 Z3 M-Coupe
Arriving at VAC from California: Must be thinking "Where's my engine!?"
Steve found VAC after searching all over North America for a solution...
He was looking for a BMW specialist that could handle the task of delivering a S54 engine capable of delivering Supercar crushing HP, as well as withstanding track use.
Owning a lovingly customized Z3 M-Coupe, the rare factory fitted production that shipped from BMW with the S54B32, he wanted a no-compromises build for one of BMWs most rare sports cars.
This red-hot project looks fast just sitting still! With a shape like a Nike running shoe and monster R-compound Nitto tires over the polished HRE wheels; this car leaves no stone unturned. The interior work, and audio is install is tremendously executed, and will be featured at a later date...
After Steve shipped us the engine, about 6 weeks later his super-S54 was completed with all the goodies one could dream... but not content with what the west coast tuners could offer, Steve decide the right choice for him was to send the Z to VAC for a total transformation...

Several weeks later, the car arrived and once in our expert hands the discussions continued.
Work commenced on an all out build to make as much HP as possible on the factory ECU. We can tell you; this wasn't just to be a looker; this car had to haul ass! After all, Steve is an enthusiast, and owner of several other supercars. He requested nothing less than stellar performance from his Z:
Z3-M sans its S54 engine, we already had his outrageous S54 completed...
However, complications arise as the confusing nature of this Z3-M baffles suppliers: E30 rear suspension, E36 chassis, E46 M3 engine...?
Example: Our outstanding Tilton Triple Disc VAC custom clutch package is prepared to be installed, but the clutch pack is delivered with the wrong spline! This car has an S54, but the transmission end is that of an S52us.

VAC Hydraulic clutch release, typical relegated just for the lucky few with race cars. This is real race technology that's street friendly.
Once the parts were all sorted out we could assemble this beats of a car...
Engine in, along with our ported S54 throttle bodies:
Details like reinforced trans cross member help to reign in 700+ HP!
...But, you can't make HP without air and fuel, So a dual Bosch Fuel Pump arrangement, just like many race cars use, is employed:
Finally, after all the necessary parts arrive, and supporting components installed. We are able to get the car together, along with a custom modified supercharger installed in a matter of hours.

Performance BMW Magazine came out to photograph this insane car and it wasn't even done yet. Feature in the works!

Monster front and rear Brembos are required with this insane power!
