911 T 2.2 rebuild - 1971

[ErrieKruger]

Bearings will be replaced ( while I'm there ). The " old " ones looks to be in good shape.

[ErrieKruger]

What do you think ?

The measurements on the crankshaft , bearing size and condition , conrod weights and condition , etc , make me believe that this is not a rebuild that was stored for 15 years. Rather a low mileage engine that was pulled and sat on the shelf for years.

Not sure what you took offense to, and why you are responding to such an old post, but he does that to everyone with an early engine- asking for numbers so he can catalog them. He is a respected member here and on the Early 911S Registry, and I am sure he did not mean to offend you.

Errie,

What do I think? I also think “Very good news indeed!”

“The measurements on the crankshaft , bearing size and condition , conrod weights and condition , etc , make me believe that this is not a rebuild that was stored for 15 years. Rather a low mileage engine that was pulled and sat on the shelf for years.”

I agree.


What will be your choice for P&Cs?
How do your Iron cylinders and cast pistons measure?
Are they in similar condition as the crankshaft?

If you need to replace them, there are lots of choices.
The best being the later technology Nikasil plated aluminum cylinders
(These were in development for the 917 when your 911 was new).
The set of 90 mm for the 2.7RS are relatively inexpensive and available with forged pistons.
This would make your engine 66x90 = 2519 cc. The CR will be a bit below 8.5:1 (your ‘T’ are 8.6:1) unless you work that issue.
This is a very nice mod if you need P&Cs.
The case & heads need modification but that is easy when you have the valves done and case inserts installed.



Now, one of the big issues will be sourcing bearings.
The issue is the regulated lead content in bearing babbit alloy has changed.
Many think to the detriment of longevity.
This is probably worthy of a separate thread.

Best,
Grady

Grady ,

I bought JE pistons and cylinders a while ago ( 86 mm ) which will give me 2300cc.
At this stage I'm still not sure if I will use them , or use them on a on a 2.0 case that I have in my fast growing Porsche inventory. Old p&c's in same condition as rest of engine.

I believe the case work will increase the compression ratio a bit.

Parts have been arriving daily - 215 flywheel to match the 901 transmission , rod bolts , flywheel bolts , gaskets , turbo valve covers , etc.

Gladly I have not ordered bearings. Which would you suggest ?

Thanks !!

[ErrieKruger]

As this is my first Porsche engine rebuild , I do not want to be too ambitious when it comes to making major changes. It will be years before I can try to match the big boys.

Looking at the technical aspects posted in the Pelican forums , I learned that I will have to crawl before I can walk. The expertise offered is amazing.

My African safari ( leaving Thursday ) , will cause me to fall behind on my planned schedule.

Don't shoot any Elephants- or if you do, don't post any videos.

A man after my own heart. I also like animals- especially the fine big cats.

I decided to make door panels myself.



Covering for a backing - will be leather



Fibreglass enforced back - still needs sound deathening layer

If anybody fell over looking at my last photo , my appologies. I forgot to do the orientation correction.

Errie,

Please include us Pelicans in your trip.
You can make your Africa trip a vicarious one for all Pelicans.
All it takes is day-by-day posts (yes, there is internet service in tourist Africa).

My only experience is three weeks in Kenya.
If you post, I’ll intersperse my pictures.



I see you have discovered the advantage of being your own ‘salvage operation’.
Having salvage gives you a wealth of unobtainable spare parts.
Disassembling is the best education for restoration.
Good for you.

Best,
Grady

[ErrieKruger]

I also want to offer advice to other newbies like me.

Take time , research , and read this forum.

If you fixed your girlfriend's vacuum cleaner , sprayed a Dodge with a rattle can , or other tasks that make you an expert , we are in the same boat - nowhere.

We had a saying in Africa - " If you want to pee with the big dogs , you need to learn to lift your leg ". After a year of research and reading this forum , I still have all fours on the ground.

Not a chance.
Anyone who can measure decimal 4-digits of a mm is a 3-leg Pelican.
(That I want to see.)

Best,
Grady

Grady,

I will post every now and again. As I lived in Africa for close to 40 years , we will avoid most of the tourist destinations. The places we will visit has not invent the wheel , or something to that effect.

I also take my wife , son , his partner Liz , and my grandson ( little Errie - a very handsome young man ) , on this trip.

As the leader, I will try my utmost to protect my clan , and refrain from fun like castrating crockodiles etc.

I know this is a engine rebuilding forum , and I'm stepping out of line. This is a picture of us - Liz , my honey Sue , me , my son Stephan , and Errie II

Sandblasting the tin , and other parts , using a high pressure water blaster with an adapter to sandblast a sludge. A very practical and cost effective way of doing this when you live in an area where you have EPA concerns.

I casting numbers on the case. 1967 2.2 ???

[ErrieKruger]

Does this mean these were casted the 50'th week of 1967 for use in a 1971 2.2 ? Or do I have my numbers all mixed up ? These are the same cases marked 901.101.101/102.3R.

[ErrieKruger]

Back home after a wonderful trip in the bushveld.

Any replies on the casting numbers posted above ?

[356RS]

IIRC the first one, 49 means that case half was cast on the 49th week and the other case half would be the 50th week.
