Hi Guys. In reading through the Petrolicious article linked below the following quote near the end caught my eye ...
“And though he’s thoroughly enjoyed competing in it, Dominik has a truly outrageous plan for its next step, one that involves more paperwork than engineering. When the 3.0 RSR came out in the early ‘70s, a lot of people wanted to upgrade from their 2.8L engines, and in California there were apparently many such swapped-out blocks just sitting around outside Porsche workshops. Somebody had the great idea to put them in the back of the 914 and made 12 examples, although no one knows what happened to any of them. The important thing though is that he got the road registration documents for the engine change, and if Dominik can find them he’ll be able to do the same conversion and get the technical passport for a prototype classic.” https://petrolicious.com/articles/taking-po...-6-gt-rally-car Does anyone know anything about someone on the West Coast installing a number of 2.8l’s into 914’s? That last sentence I quoted suggests the 914’s converted to 2.8l’s were completed in some quasi-official(??) manner somehow legitimizing the configuration for European vintage racing as a “classic prototype”. Opinions anyone? Any truth to this? Anyone heard of “road registration documents” for such a swap? Just wishful thinking for someone involved in European historic racing? ... or just BS? |

No official Porsche cars ever came out of California that I’ve ever heard of
Not many race shops had manufacture status If they existed they were conversion/hot rods ... not official |

Probably a shop that got its hands on one of the factory GT kits and built a car using a 2.8L motor. Back in the early/mid 70s, I'm not sure if there was even a class for a 2.8L 914/6 - they were homologated as a 2.0L.

In the 1970s and 80s IMSA and FIA (World Championship) were sanctioning races together, some of these races were the 24 Hrs of Daytona, 12 hrs of Sebring and Watkins Glen 6 hrs. 914s participated in some of these races up until 1987 and thru IMSA rules the cars were allowed first 2.5L then 2.8L and finally 3L engines. Maybe someone is using this as a loophole??

I would not be surprised if there was an allowance for a 2.8L 914 in IMSA; SCCA was all about being stickler for the rules, John Bishop was all about getting the numbers up.
Well, as long as you didn't piss off their bread and butter, then they'd put you on the trailer. (IMG:style_emoticons/default/smilie_pokal.gif) |

There were definitely US classes, places to run a 2.8. Etc
But no FIA recognition. No classes in Europe No manufacturing status for hot rods and US rules that I have ever heard of |

As someone who competed with a 914-6 in IMSA back in the day we were allowed to have up to a 2.5 Liter engine done one of two ways. Short stroke or long stroke with 85 or 87.5 pistons were the best options that most of us ran.
A 2.8 was never legal though some people ran both 2.7 and 2.8. The 914 was then basically regulated from competition in the mid 80's. |
