numbers matching I suppose it's true, "anything can be saved", but at what cost and what value. We have been successful in the historic building restoration business for many years and can fix anything, but often it is less expensive and will provide better long term value if we replicate with new materials. From what I understand Classic Porsche has new cases, now we are really digging into our pockets. If I have the story right, Porsche had some nos 3.2 engine case blanks that they had machined and sold. Now that they have the setup ready to go, it would be nice if they continued to make them. It's still not inexpensive once you add up all the parts to complete an engine but greater availability helps. It also helps to consider that while the cost of a rebuild isn't cheap, it wouldn't be unreasonable to expect the engine to last most of us for the rest of our lives. Most of us use our Porsche's as play cars and 2-3K/year is probably average. |

From what I understand Classic Porsche has new cases, now we are really digging into our pockets. I bet those cases are close to $10K. Has anyone heard from Adam (catorse)? He makes the new 3.6 cases and a few guys on the bird were trying to get a hold of him. Anyways he said they are looking at doing the 2.0-2.7 cases, but they will be likely about the same cost as the 3.6 case, so last I checked IIRC it was $6500. |

In the grand scheme of maching up mag cases, $6500 for a completely new casting CNC machined, would be sort of "resonable". Still wouldn't be Mag which would be sort of a downer for me but I get it. Hardly anyone casting Mag these days.

For me, once you add in the durability, power, fuel injection and final cost, the 3.2 makes sense. That doesn't mean it's the best. It just checks a lot of my wishes. Can't argue with it, and mine would be a 3.2-based 3.4 with Motronic if building a 914-6 GT… I still want an engine builder friend of mine to build me an aluminum case 2.0 hotrod that will rev to 8K+ and make glorious sounds. Just because. But this isn't far off from my dream for a narrow six-cyl 914: a mag-case 2.2S with MFI that revs to 8000 rpm backed up by short gears for 2/3/4 and a cruiser 5th. In the grand scheme of maching up mag cases, $6500 for a completely new casting CNC machined, would be sort of "resonable". Still wouldn't be Mag which would be sort of a downer for me but I get it. Hardly anyone casting Mag these days. Not sure about price, but machined mag case got FIA approval for early 911 race cars—and startup doesn't look too far off. https://www.early911sregistry.org/forums/sh...c-Racing/page20 Attached image(s) ![]() ![]() ![]() ![]() ![]() ![]() ![]() |

Most of us use our Porsche's as play cars and 2-3K/year is probably average. True and true. The 2.7 engines had a good run, close to 50 years and often hard/hot miles. Our 914/6 may get 2k miles per year at best and if it lasts 50 years I will be 120 y/o |

So there's billet aluminum ($12.5k) and billet magnesium cases ($?) out there. Interesting. Can see it for racing applications, less so for street cars. Next one I do will be mag case, and there's something to be said for keeping a case that came out of Zuffenhausen once upon a time, even for a mere six conversion, but one does begin to wonder: What's the life expectancy of the base metal in a 50yo mag case? |

Pretty sure that ITG small bore case pictured above is aluminum? I've been following his thread on Pelican. Would be interesting if it were mag ...
Mag cases are needing more work in general. They're fragile, and 2.7L motors were hard on them due to heat and pulling studs. The 7R cases (late 2.4 and 2.7) are considered the best from a structural perspective if you can find one that hasn't been abused. |

In the grand scheme of maching up mag cases, $6500 for a completely new casting CNC machined, would be sort of "resonable". Still wouldn't be Mag which would be sort of a downer for me but I get it. Hardly anyone casting Mag these days. You might be surprised, particularly in "Aerospace Alley." (IMG:style_emoticons/default/smile.gif) I've gotten magnesium sand castings for some racecar parts from some local vendors who do mainly helicopter work. Pretty sure that ITG small bore case pictured above is aluminum? I've been following his thread on Pelican. Would be interesting if it were mag ... I thought mag, but crazy heavy (like 65#). |

He will pair it down. The early 911 guys are running out of 2.0 aluminum cases. |

Cabman,
I have a ‘67 sand cast aluminum case engine, built as a 2.4, that I have been thinking about selling as a long block. Unless you are set on larger displacement. PM me for details if Interested. Thanks |

Spend an hour or building a shipping crate to send our 2.7 case to Ollies. After doing my research it appears as though they are the men.

They did a great job on my 2.4L If you didn't follow my thread, the only hitch I ran into was needed to use Porsche OEM bearings for the mains as Ollies recommended. $600ish for the set not including #8 nose bearing. Other than that I got all my bearing cleanances within spec. Used Clevite for rods - no issues. |

Ollies contacted me last week, they are back logged about 14 weeks. They explained the main bearing bores grow about 2 thou in the horizontal direction and shrinking about the same in the vertical dimension. They will take a few thou off the mating surfaces and rebore the mains to a standard bearing set.

Could you keep us posted on turn-around and itemised invoice ? I see a 2.7 in my future |

These magnesium cases are approaching 50 years young and I'll bet plenty of hard miles. They informed me about $2.k for their work |
