First some background on the project. Makrutzki told us that the first discussions for Project Gold began about two and a half years ago, and they began because of a confluence of happenings at Porsche. Porsche's 70th anniversary of car building was coming up, and Porsche Exclusive Manufaktur had just launched its own special vehicle, the 911 Turbo S Exclusive Series. Porsche Classic, the department that handles restorations, was wanting to do something special, too, inspired by the Exclusive Series 911. Fortunately for the department, they noticed that there was still a complete, bare production-line 993 chassis built in 1994 that nothing had been done with. All of this led to the start of Project Gold.
For a bit over a year and a half, the Porsche restoration team was working on the car. The team decided that they wanted it to very much be a 993 with similar specifications to the original, rather than an over-the-top show car. This is why it has a twin-turbo 3.6-liter Turbo S 993 engine, and not something more powerful from a newer 911. That doesn't mean there wouldn't be any upgrades to the car, though. The chassis did start as a plain 911 Turbo, not a Turbo S, and it lacked the fender intakes of the higher-spec car. The team wanted to add them, which turned out to be quite difficult as there was no tooling to add the intake inlets after the body had been built. So those intakes were added by hand, and to ensure they were properly shaped and sized, Porsche brought in people that worked on the 993 production line to help inspect and re-create them.
The attention to detail didn't stop there. Makrutzki told us that although Project Gold's engine is technically a stock Turbo S engine rated at 450 horsepower, it's probably one of the better examples. The team took the engine apart and replaced the various internals such as the pistons and rods with the lightest examples they could find in stock. The engine was also ever so slightly bored during the rebuild. Makrutzki said the same method of picking the best components at Porsche Classic was also used for the 6-speed manual transmission. The suspension also sees a slight upgrade with the shocks. The original 993 shocks had been out of production for a while and unavailable, so Porsche used more modern shocks, and fitted them with original-style casings.
The interior naturally received much care and precise work. Makrutzki said that the team didn't really have a specific look in mind, except that they wanted to have elements of the Exclusive Series 911 and maintain the look and feel of the 993. The team went through various samples and would look over the new 911 to get ideas and cherry-picked what felt right. Aside from the extensive use of carbon fiber and fancy perforated leathers, the Project Gold car features completely custom front seats not shared with other 993s.
Makrutzki also told us a story about the headliner of the car. It's a leather headliner made in two layers, the outer one is black with perforated stripes, and under that is yellow leather that shows through. The team wanted everything in the car to feel as close to a car from 1998 as possible, and that led it to use a sewing machine from that era so the stitches had the right length and pattern. Each time they tried to finish the stitching for the stripes, they found that the stitches were curving one way. They couldn't find any way to fix the machine, but they eventually figured out the exact amount of curve, and factored that into the line to follow when sewing it up, leading to nice straight stripes.
It may be a while before we see another car like this come out of Porsche. We learned from Makrutski that the car was entirely built by the Porsche Classic restoration team. The team comprises the people that are working on restorations for paying customers, so they already have plenty to keep them busy. Porsche itself hasn't announced any plans for future projects either, and it sounds as though there aren't really any other production chassis laying around like with this 993.
With this much care put into it, the Project Gold 911 Turbo ought to make its new owner very happy, even if it can't be driven on public roads. How much the owner will have to pay has yet to be seen, since the car will be auctioned off by RM Sotheby's on October 27 at the auction house's 70th Anniversary of Porsche auction. We imagine it will be pretty pricey considering that it is a one-of-one car with no announced successors, it's an air-cooled 911 and the proceeds will be going to charity.
