We are attempting fitting a 2.7 into our 1974 rustout hulk but have come across another hurtle. I have had a 2.7 kicking around for awhile and "assumed" we could go through it with new bearings/rings/..... and have a nice power plant. Not so quick there. The head stud issue is well known and I recently found when the magnesium cases are disassembled the crankshaft bores no longer return to a round/aligned condition.
I want to believe someone out there can get these magnesium cases in serviceable condition with good crank bores and good head stud bores. thanks |

You can always find another 2.2, 2.4, and 2.7L from somebody in running condition. PM me I have 2.7L on a stand right now I am planning on selling. Put it in and run it.
Why a mag case engine, Conversion is easier, no special fly wheels, its a bolt in operation. Mag case sound right tad bit lighter cheaper to purchase Why go latter 3.0 - 4.0L more power perceived better reliability easier EFI options from the factory did I mention more power Some people need it, some don't. 914 like any car a sum of the parts, and are an system unto themselves. Just remember as your displacement increases your bank account decreases. But then I fight this battle with every sports car I own. My Boxster build I am currently looking at a 3.8L 355HP engine thinking, yeah I need that. I have driven my Boxster for 1000 miles. (IMG:style_emoticons/default/screwy.gif) |

(IMG:style_emoticons/default/screwy.gif) From what I can tell aluminum cases are generally more forgiving than magnesium, I am getting a 2.7 education for sure. Basically we are making the /6 conversion for added power, the finish product will not see a track or car show, but reliability is up there for a priority. The case I was hoping to use had previously been "repaired" with a timesert's and have since failed. I found a replacement case from Cali., when we unpacked it the head stud sockets in the case had also been "repaired". Both cases left little/no material left to work with. Back at square 1, looks like I will be shaking the money tree a bit more |
