In the first installment of this build, we showed you the tear-down of a well-used 911, and followed it through paint work. Now, take a look at the suspension and electrical work that was done. The before pictures show this car was driven hard! You’ll be amazed at the attention to detail that went into restoration and reassembly.
What makes the 911S so much fun to drive is the outstanding control from the suspension and brakes. The rear engine posed a unique design challenge, and the 911 suspension broke new ground for Porsche. In the front, MacPherson struts on single transverse A-arms connect to longitudinal torsion bars. Rear suspension comprised transverse torsion bars and semi-trailing arms. This was a big improvement from the suspension used on the 356. This 911S uses Koni sport front struts and rear shocks. Vented brake rotors help to keep the brakes cool for improved performance.
Take a look at the suspension and brakes before restoration:
Here you see suspension pieces disassembled and bead blasted in reparation for refinishing. Every fastener was cleaned and refinished (or replaced where needed):
Now, check out the finished, restored suspension:
For such a small car, the Porsche has a lot of wire. Every circuit needs to be documented during disassembly. Color-coded wire helps, but it’s best to mark the wiring and photograph the route and mounting location of the harness.
Here you see the front and backside of the fuse panel:
Here (left) you see the engine electrics, including the ignition amplifier unit and voltage regulator. Also pictured (right) is the back side of the oil pressure/temperature gauge, with color-coded wires:
And here is the restored dash with reconditioned gauges:
The stock, 2.4-liter flat-6 uses mechanical fuel injection, and is mated to a 4-speed transmission. As with all aspects of this restoration, the engine and transmission were completely revitalized down to the smallest detail, including correct markings and decals.
Here’s the engine during reassembly (left), and installed back in the car (right):
All told, months of preparation and exhaustive work have resulted in a stunning automobile. Thanks to the careful hands of knowledgeable craftsmen, the car has literally been given new life! If you have any questions about this restoration, feel free to drop them in the comments. We’d love to share the experiences and information we picked up along the way.
