Motor numbers.

Hello all! I bought my first 911, a 1981, this past Friday and just learned of your board tonight. What a great resource. I doubt I will be able to contribute much, but I am very thankful this kind of thing is around.

If I may ask a question: Do all the internals of a 911 motor have a number?
My motor needs to be redone as it smokes alot and has little power. I friend of mine has accumilated alot of good spare 911 parts - cranks, rods, pistons, cases etc. He has a building FULL of stuff. He said I could help myself to anything I needed so long as I was willing to do the search and rescue work. Obviously, I want stuff to fit my 3.0L and was wondering if I could possibly group parts from the same motor together.

This will obviously save me alot of dough, but I dont want to do start something I can't finish.

Welcome Newbie. I would think you have a lot to do before worrying about parts. I suggest using the search function on this site to learn all you can before begining to get into your motor. Look up related topics and get some idea what you are into. Could be valves/guides, rings, head studs (EEK) or a zillion other things. Time for a bit of study Some posts are quite funny. (Leland)

I HIGHLY reccomend reading anything from Early S Man.

Thanks for the information. I am going to have the motor rebuilt by a shop. I just want to have a good inventory of free parts for when those guys start telling me what I need. My buddy said he as had all the parts examined and are all in super good shape. To see his two Porsches, and knowing how anal he is, it is not hard to believe. Anyway, I just wanted to know if there was a way to match componets up that go to the same engine. He has sorced the parts from three diffrent 3.0's so I know the matches are in there, its just putting them together I am worried about.

Newbie,

For some engine parts, like connecting rods and cylinder heads, yes, there are unique part numbers that do identify which engine they are used in, but for the vast majority, unless still in a factory box, no. Cylinders and pistons, for example do not have part numbers on them anywhere! It takes pictures and calipers to identify most P/C sets!

Your best bet is to get a set of factory service manuals and parts catalog to help you identify the parts and specs! The so-called 'spec book' also has valuable information.

Hi,

Be sure the "shop" you are going to use has a good reputation. If you use parts from your "buddy", the shop may not warrenty the engine when they are finished. Be sure they are full invoved in the decision to use "used" parts. Re-building is an expensive operation and if done right the engine will last a long time. The shop should be able to tell you which "used" parts will work OK and which parts to by new.

Thanks a bunch! That is really good advise on asking the shop upfront about uded parts. My buddy is a life long frined of over 21 years and the shop we are going to has done most of his work.
