AndrewW Posted 29April, 2017 Report Share Posted 29April, 2017 There is a bit of bad press on the 2.7 ltr motor on the net, I am wandering if they are as tragic as the articles advise. Is the magnesium block more prone to failure with age ? Is a recon motor ok to own ? Does the motor devalue the car as a opposed to a 3ltr SC ? Are they easy to live with ?

michel Posted 29April, 2017 Report Share Posted 29April, 2017 Engines do they have a soul ? If so a 76 with SSI's and a fruit tuity exhaust is just as good as a 3.0 (IMO). Is a poor 3,0 still better than a good 2.7?Don't believe everything on forums. But if you do, what's your opinion on sportomatics? Are the threads you read on US forums? 2.7's suffer some issues, but it's more an Issue particularly on cars with thermal reactors, we didn't have that here.Dothey devalue a car? I don't think so and no more than any other motor in poor repair. cheers Link to comment Share on other sites More sharing options...
micknine01 Posted 29April, 2017 Report Share Posted 29April, 2017 I had a 74' with an original 2.7, never gave an ounce of trouble, was one of those cars you would drive anywhere without worrying about anything Link to comment Share on other sites More sharing options...
MFX Posted 30April, 2017 Report Share Posted 30April, 2017 I am rebuilding mine in the next few weeks, and I am upgrading it a long way. It will be interesting to see how it goes, but the legendary 73RS had a similar 7R case and it is revered. As Michel said, as long as it doesn't get too hot, it should last.

bumble Posted 30April, 2017 Report Share Posted 30April, 2017 Absolutely nothing wrong with a 2.7 - after all, it is the motive power behind one of the most desirable models in the Porsche universe - the 2.7RS Carrera!. It should be remembered that the RS Carrera had a C/R of only 8.5:1. Most reported problems were caused by excessive heat, particularly the US cars which had to run with restrictive smog gear which would a. cause premature valve-guide wear and problems with pulled head studs.To prep a 2.7 road engine assuming normal measurements carried out:Employ Case Savers/Timeserts7R is the strongest mag case - most 2.7s are I thinkIf it has a 5 blade fan, toss it and get an 11 blade oneDon't get too ambitious re power and add better oil cooling is used in hot environs. It should last almost forever... Link to comment Share on other sites More sharing options...
