2.7L, So why is 2.7L the motor to avoid? Options

[qa1142]

If someone is going to start looking for a 6 to build what do you want and what do you want to avoid?

2.2

2.4

2.7

3.0

3.2

I think a lot of the perceived issues with the 2.7 are urban lore. The stud issues with the 3.0 seem to get glossed over in discussions like this.

I'd ask a bona-fide mechanic/machinist who has seen it all to give you his opinion.

BTW, I have a '74 2.7S. I rebuilt the motor last year after 105K and its studs were fine. I installed SC cams with a M&K muffler and the car really hauls the mail. I recommend the 2.7.

2.7s are Great motors in a 914. Yes they did have Stud problems, but if you are finding an engine these days, the studs have probably been replaced. The correct studs to use are Porsche Steel studs, not the Divilar(?). The other perceived problem of a 2.7 (and partial cause of the original stud issue) was the heat that was created by the Thermal Reactor exhaust system that Porsche used to combat the stricter Emission standards of 1974. Again these exhausts have long been scraped as they were more trouble than their usefulness and would not be used in a 914. The 2.7 7R case is much stouter than the earlier 2.2 or 2.4 cases. You can easily make a 200+HP on a 2.7 case. (see my Pro-Built 2.7 in the classifieds)

And yes, while 3.0s are almost bullet-proof, they also had Stud & Tensioner issues
