On 911s and 930s produced in 1976 the fan strap was rotated to the left so that the fastener was situated at the very top. The fan decal was then placed to the right of the fastener. It isn't as clean looking as the earlier positioning where the fastener was turned all the way right to be out of the way. Engine rebuilders are so used to the earlier style that on restored cars you typically see it positioned the old style way, but every original engine I've seen has them positioned on top. Of course, it could have just been worker installing them had a specific habit and all cars he touched were that way vs another worker who would do it slightly differently.

We changed the fan strap to the bolt at 12 o'clock....I guess I could get used to that, but certainly whoever worked for Porsche and made the decision to mount it there got voted out and they returned to the way it looks the best. It would really be interesting to know the real details from Porsche. Certainly someone over there reads this forum.

Fun with the Wiring Harness

I'm quite a bit behind in posting updates on the restoration of Carrera 2.7 MFI #9050 and plan on catching up over the next few weeks.

Prior to the start of metalwork and paint the complete wiring harness had been removed and set aside. Dealing with the wiring harness is a time consuming process, but absolutely required to make sure everything will work once reinstalled.

First step is to stretch the entire harness out and make sure all the bits and pieces are there along with key electrical components. Jonathan at German Master Tech is clearly enthusiastic about the tedious process of testing every wire and repairing any issues that crop up.





Despite the Carrera having been stripped down to parts a decade or so ago very little of the electrical components were missing. During DOT federalization in the mid-1980s this Carrera was converted to sugar scoops, among other changes including door bars, DOT spec lenses and reflectors. This required sourcing a set of H4 headlight buckets with the correct Bosch logo lenses. The original Blaupunkt radio had also been replaced with an aftermarket stereo sometime in the past. We sourced a 1976 Köln model, with correct date codes and all the corresponding documentation, from Germany.



Once the wiring harness was completed it immediately went into the chassis, though in the photos below still required some final tweaks.

Well worth the detail expended. It will be a beautiful example.

BTW,I think I recognize that fan shroud.

While we certainly could have installed a modern replacement, such as the Dansk Sport muffler, this project is all about the little details that make it original.

The rest-of-world 911s — including the 1976 Carrera 2.7 — were equipped with the Bischoff 911.025.01 two-in, single-out mufflers during 1974-1976 (and possibly beyond). The North American Carrera models were equipped with the same muffler in 1974, but starting in 1975 they switched to a revised design for emissions. This makes having an original muffler here in the States quite rare as not only have most rusted out, but if you ever wanted to find a replacement there would be few options.

Bischoff must have produced these mufflers in mass quantities as the date stamp on the 1976 Carrera 2.7 muffler was May 1974. The muffler was in ok shape under a cursory examination, but once inspected closely there were some signs of rust that had to be taken care of as well as some scrapes to the tip in the past. The repairs were carefully done, taking great pains to preserve the original factory welds as well as the part number and date codes on the bottom. While it would certainly have been much cheaper to just buy and install the best muffler Dansk offered, the goal of this project is authenticity and originality wherever possible.

The rear valence and rear side skirts shouldn't have texture on them (not to mention the texture was too fine to be Porsche factory original). This was a mistake by our painters that is being corrected this week to be the original flat finish.





The original muffler tip was repaired by welding additional material onto the end which had been ground off and then repainted the correct black finish.



Bischoff 911.025.01 muffler with May 1974 date code and original factory welds for the flange.



Final installation of the muffler gets the Carrera one step closer to firing up.

Great attention to detail Ryan. The square end exhaust tip is very interesting. A carry over from the chrome tips on the early cars.

More details on the restoration of 1976 Carrera 2.7 MFI #911 660 9050 as we head towards the finish line. German Master Tech has been busy assembling the Carrera back to its original glory one part at a time.

Original aluminum front cross member, steering rack, and anti-sway bars installed.



Trombone cooler and horns are a visual symphony.



Gauges freshly restored by Palo Alto Speedometers make the interior look like it is starting to come together. Palo Alto left the backs untouched so all the original date codes are still in place.



More parts return from the platers ready to be assembled.

Painting the Details

There are many little details that all add up when you are restoring a 911 for top-level concours. Sure, you can buy new parts from Porsche dealers, parts specialists, etc. but wherever possibly I think its best to restore the original parts. In some cases, like the red defrost knobs, the replacement parts may not be available or no longer have the correct patterns engraved. Some of the details that are often overlooked are all the little details that Porsche painted, intentionally or otherwise, when the 911 was being produced. It is important to keep your eye out for details the Porsche factory introduced as part of their manufacturing process.

Jonathan repainting the detail on the defroster knobs prior to a final polishing.



Photo showing the original black paint around the chassis tag so that the paint can be reapplied in a similar manner.



Jonathan painting the edges of the doors just like the factory did to ensure there was a crisp line on the doors where the door panels didn't cover. Note the original grease pencil markings on the door were preserved when the door was repainted.



The factory dripped their paint too...



In this photo you can see a small dent below the fuel tank which is on all 911s of that era. Another example is the black overspray from Porsche painting the smugglers box with the lid open and not entirely masked. Reproducing these details is what makes a top concours level restoration really stand out.

What kind of paint is used to paint the door edges black?
I'm currently redoing my doors as well, and might want to do them factory correct as well.

Car's looking great.

Wurth Satin black is probably the best paint to duplicate the effect that Ryan has done on the doors of the Carrera.

Nicely done Ryan. The replications of the blacked out areas show great attention to detail. Now you need to brush some brown adhesive on the inside of the trunk.

I notice you didn't use black paint over the raised metal where the chassis number is stamped. Was this discontinued by '76 or was this a matter of which painter did the car that day? The smuggler's box lid seems to have recieved that treatment also as some, including my Carrera, has thinly applied body color paint on the top of the lid and black on the inside.

Brian, when I took the photo the chassis stamp just hadn't been painted black yet. You are correct it is a very thin layer of black paint. The smuggler box lid was painted black on the inside, and this is why you often see black overspray on the painted surface below the smuggler box where the chassis stamp. Depending how well the smugglers box was masked off black paint sprayed through where the hinges are and left an impression that looked similar to the lid shape.

Any pics or details about your fuel tank?

What did you use to restore the outside?
Any paint color code?

One thing I am not totally positive about, but the oil drain plug should not be the one you have pictured. In Germany to prevent people from doing their own oil changes, Porsche, did not install a drain plug. I know this because I discovered mine did not have a drain plug and someone chimed in and gave me the background history.
I only mention this only because you are trying to maintain originality wherever possible.

I've never heard this story...and can't find any data to confirm, but do find people referring to it as an "urban legend". In both the German and US PET parts catalog it seems the same identical drain plug and cover is listed, though the parts catalogs were updated over the years so they aren't that reliable for details like this. I found a photo of one other 911 that had the cover without a drain plug.

Actually from what I've read these oil sump plates without the plug are from later 911s (1983 and later) when they moved the drain plug from the sump plate to the block. I suspect those without the drain plug on earlier 911s are actually later replacements where someone ordered the wrong part.

According to my mechanic, the factory simply stopped providing sump plates with a drain plug, without rhyme or reason. People started speculating that it was to force them to go to the dealer for oil changes, or to buy the gaskets, also thereby risk making a big mess by removing the whole plate. Some said that the have been cases of ripped plugs by bottomoing the engine out.
Most likely, the factory did what they do best about owners of older (less profitable for them) cars: not care.
