Porsche 911 S

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. 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 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 all untouched and original. Interior, dash and rear seats are original, even the shocks for the front hood are the original dated 9/66. 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 update in the winther months of 2023 . We have good indications that these engines where made / tuned by Gerhard Mitter and they all came on repalcement cases , what we dont know , did he do them in his shop for Porsche or how did they end up in these cars !! This is however very well understood and accepted among Porsche collectors as the history and provenance all goes with the body, hence the importance of documenting body numbers and numbers in the body in general

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

We got much more pictures and history of the car!
