I’ve tended to shy away from Porsche work in recent years. However, I made an exception for this customer and project. The car is a 1979 911SC finished in a factory Cashmere beige, and equipped with a very homemade turbo conversion – more of this is covered in an earlier post.
Here is what we started with. There is an EFI conversion lurking in there.
Stripped. Welded. Body worked. The engine bay had nearly a dozen extra holes, in addition to welds and funky repairs. We did put best to remove them all, and clean up years of damage on the rear shut panel from hasty mechanical work.
Before laying down the color, we epoxy primed and re-textured the engine bay.
A color-matched engine shroud.
Moving along.
So, this car was previously fit with a modified CIS manifold. Not an ideal choice for a turbo-conversion for a number of reasons. We modified a 3.2-liter Motronic manifold to fit, and rotated the throttle body approximately 60 degrees rearwards. This involved modifying the bell crank and throttle linkage, as well modifications to the stock throttle body for reverse operation. Stainless fuel lines were also fabricated with AN fittings to accept the fuel rails.
All of that intake work was necessary to fit an intercooler underneath a ducktail engine cover. The intercooler is a factory 930 unit, which has been reversed 180 degrees and modified to fit. A custom tapered charge pipe was also added. Clewett Engineering’s plug wires with a woven shield are a nice touch, IMO. To be continued…
