- - 81 vs. 82 (http://forums.pelicanparts.com/porsche-911-technical-forum/632743-81-vs-82-a.html)

What were the changes in the SC from 81 to 82?

I have a 81 Targa and am looking at an 82 Coupe.

From what I just read in Paul Frere's Porsche 911 Story, nothing. Maybe some cosmetics, but nothing major according to Mr. Frere. Of course others know much more than I, so maybe someone will think of something.

Juan is right, no differences.

More differences will be found between euro and us spec cars. They tend to be optioned differently and I believe the eruos are just a bit more powerful. Besides that, the differences are the options they chose back in the day.

Simon's Porsche 911 SC Site Not much it seems.

The cam nut changes from a 46 mm wrench-size (thread M27x2) nut to an M12x1.5x50 hex-head bolt.
A new P-tool (9191) is required to hold the cam.

This is the 911’s first year for the ‘oil trap’ next to the oil fill cap.
This is an easy way to distinguish between the years.

This is the first year for the integrated voltage regulator in the alternator.
This is less reliable identifier as many earlier 911s have been updated.

The scale for the oil temperature gauge (again) has new graduations.
Could someone post an image, please.

The differential spider-gear shaft is increased from 18 mm to 21 mm requiring new spider gears, shaft, threaded pieces and differential housing.
This is a worthwhile update for earlier transmissions back through 1970.

Needless to say, the model year can be identified from the VIN, chassis build number, engine number and transmission number.

Best,
Grady

Awsome Grady...

The integrated voltage regulator was the one I had headr of before but could not remember...

Thanks a bunch.

Grady - Porsche should put you on the payroll as a consultant. I am willing to bet that you know more about older Porsche cars than some of the younger engineers at Porsche. Thanks for all you do on this forum.

Can someone post a picture of the oil trap next to the oil fill cap that Grady mentions?

Ditto that last acknowledgment of Grady's contributions.
