It was sold w/ factory recaro seats & limited slip diff & Webasto, This is a dinosaur offered by Porsche prior of the iconic 911R and Sport & Rally kits , this car was possibly the very first time Porsche offered a customer competition 911 build from factory !!!
Finding an unrestored, genuine factory-built 911S competition car in 2025 is an unusual occurrence and likely a chance not to be repeated. In fact, finding any early 911 with racing history in period, has become a real challenge.
Ingemar Buström was racing this 1967 911S in the golden years of 1967 & 1968 when the Porsche 911 model had a breakthrough in Swedish national group 3 , Burström was racing this 911S in the 1967 SM season, together with famous profiles like, Kent Frohde, Anders Josephson & Picko Troberg and Zylwe Rahm
its one of 5 special ordered 911s GT / Competition spec racecars for the 1967 Swedish championship series with the rare engine performance upgrades.
Attached is a newspaper article from December 1966, where Burströms upcoming delivery, Burströms 911 is specifically highlighted with a higher performance output of 180hp corresponding to Kardex, the photo is taken late 1966 outside the Scania Vabis headquarters in Södertälje Sweden. Ingemar Burströms Porsche was delivered few weeks later of this article., we got full history of the 5 cars and there where abouts, 4 are still left
Kardex explained:
Hand writing “Achtung motor frisiert auf 180ps, keine guarantie” meaning power increase with 20hp to 180hp and voided guarantee” these modifications was carried out from factory under guidenence of Herr Gerhard Mitter factory driver and owner of Mitter Tunning and this particular modification which is believed having been seen on very few Kardex files, meant these few cars was unofficially referred to as the 911S with “Carrera” engine technic. with Carrera Pistons etc , Do also note the car was ordered by the racing driver Ingemar Burström being the first owner “Wagenbesitzer 1”
Burström was noticed by the media in the 1967 group 3 season, for his Porsches results.
Headline reads “Better and Better”, the article below highlights the Carrera parts as a game changer
The body of the car is in a very good shape despite the car got a turbo body kit ! minor rust but mostly solid compared to usual rust of these models. What’s exceptional about this car, is that it seems, like they just fitted a body kit on the outside to the car, once in the 70’s , and it have not been on the road since , so most is still preserved, meaning that doors has original red paint on the inside,all date matched original 911s gauges, relays, , washer bottle , wirring loom all untouched and original. Interior, dash and rear seats are original, even the shocks for the front hood are the original dated 9/66 from Stabilus All the important details are intact which couldn’t be expected on car this old. there is NO FAKE VIN STORIES TO THIS CAR
The engine number is the same as the engine number in the Kardex, but a cross check with the part number on the engine casing indicates it’s one out of roughly 2000 aluminum replacement cases BUT according to our research and updates . We have good indications that these engines where made / tuned by Gerhard Mitter and they all came on repalcement cases , what we dont know , But It is very interesting and these cars, and especially the role Mitter played, is not well known at all and and I still recive more and more info on Mitter ,It is very interesting. This is an area where new information is still coming to light all the time. What is written in the books is not the whole story! and also more and more Porsche historians are surprised how much this car had inpact,on later options even in the same year 67 , like the Rally kit , Sport kit,
We have heard stories from people involved in racing 911s in the 1960s that Mitter was the guy, who made the most powerful engines. He used more compression than the factory was willing to do ,and ultimately achieved 230+ hp from the two litre engine.
Finding an unknown 67s competition 911 is not something likely to happen again, this car should gain massive crowd interest when restored , and presented at events regardless of where in the world, and owning this car also gains you access into the world’s most prestigious car events, where only cars with period race history will be accepted. Meaning this car is an admission ticket to star events like
Rennsport reunion where its little brother is allready taking part of and , Tour auto , Ice races
We got much more pictures to share and history of the car ,and the 3 other cars as well and there wherabouts
