This 911SC was acquired by one of our customers earlier this summer, and may present like a relatively stock narrow-body G-series 911. However, it packs some extra punch, in the form of a turbo setup. The modifications were undertaken by the previous owner, with lots of input from the Pelican Parts forum and whatever was available in their garage. It’s a great concept, though it lacks in a few areas, and is in the shop for some tidying up.
Mechanicals aside, we decided to start with a fresh set of RSR-style 16″ reconditioned Fuchs for some inspiration.
Then we started revamping the turbocharger installation, piece by piece, beginning with the turbo oil return system. Unlike the factory 930 setup – which utilizes its own oil scavenge pump and plumbing, this turbo conversion utilizes a simplified oil return system that returns the turbocharger’s oil to the crankcase and primary scavenge pump. Starting with this large chunk of aluminum, we began turning a new sump plate.
The old sump plate is shown on the right. It was a little rough, and too much of a liability to have dangling beneath the car. The new sump plate is shown on the right awaiting some countersunk mounting holes, and final machining.
The new 5/8″ turbocharger oil return line, made from stainless steel, flared on one end, and tucked up as far underneath as possible.
A new ducktail from Gary Stratton. Ready to be wet sanded and polished before reassembly. Much more to follow on this project including a 930 intercooler install and a Motronic intake manifold swap.
