Well done
 

What an awesome thread this is - well done!

Over this winter I am planning to rebuild the yet-unopened motor on my 1980 RoW SC - it has one broken stud - and this thread has inspired me :cool:

Could you please share the costs of the rebuild? Of course, I'm also hoping that I can re-use the pistons.

I will post here once I start the rebuild, probably in November. I am still driving the car ;), even with one broken stud.

I haven't added the cost up yet, but I'd say it's over $5K. If you need new pistons and cylinders, add another $4K to that.

I'm glad you have enjoyed the thread. I learned a ton and someday when I have a better work space I'd like to do another one.

Excellent thread.
I was re-reading it an saw the photo "Where the air pump used to be". As far as I am aware, Euro cars did not have an air pump. Please correct me if I am wrong.
(Mine doesn't, but it is older).

My car did have an air pump, and I now have those plugs on the exhaust side of the heads. Here is a picture of the car when I got it and you can see the air pump on the lower left side of the engine.

You can see the little plugs in this picture.

Re - having valve lash (I assume, not valve timing as such, which is really cam timing) off because the rocker wasn't on the cam base circle is a problem easily avoided if you take a look at each rocker before you adjust the elephant foot. You can see if the rocker is sitting on the base circle or not easily enough. Especially while the engine is still on the stand.

Re - air injectors. I, too, didn't think the Euros had those. And it wouldn't just be something Federalized for gray market importing, because the non-air injector heads didn't have the boss bored and tapped for them. So it would be quite a job to add them in when the car got off the boat. Are you sure the engine serial number is for a Euro? But maybe a couple of us are wrong, and the shop guys have seen Euro motors with the air stuff?

I don't know how I screwed up the valves, but whatever I did, I did it on the first one and continued through all of them because they were all equally wrong. Live and learn.

Re the air pump, my engine serial number starts with 63C which is definitely a Euro motor. I did buy the car from California where it had met emissions (and had no power) so maybe it was added. It had the air pump and a catalytic converter. I guess it's possible the engine was rebuilt at some point with different heads that had the ports but I don't think so.

The 82 Euro SC would have the larger 39mm intake ports that the 78-9 US cars had, along with the 9.8/1 CR. The larger ports meant the manifolds/runners were a bit thicker. When you look at a smaller port (34mm) and a big port motor sort of side by side, you can see the difference in the runners.

Do you recall if your intake ports were larger than the exhaust ports?

My bible, Bruce Anderson's 911 Performance Handbook, shows all '82s as having the smaller 34mm intake port, but I am pretty sure that is a mistake in his voluminous chart. The bigger ports are one reason, along with the 9.8CR, that the late Euro SC is such a potent motor.

I know it has the larger intake ports, because in the catalog here, if you order the replacement rubber boots for an 82SC they are the smaller ones. Ask me how I know. I kept trying to fit them onto the runners and finally said, damn, these must be the wrong size.

Euro engine had the air pump stock, but did not have the cat converter. That was added for federalization/importation process.
81-83 euro SC
9.8/1
Big port heads
Large intake runners.

Thanks, Doug

No more guessing.

Did the Euros have a good exhaust as well - 3 into one into the muffler? Or did they have the right side crossover, but just not the cat?

Yes thanks for the info Doug. The Euro cars had standard heat exchangers with the crossover to the "Euro premuffler" to the standard banana muffler. Mine came with a USA cat (CA car) but I bought a Euro premuffler from another Euro car and actually ran that exhaust for my first few races.
