serial # on engine

The only number I can see on the engine is *6130463* what is that? This is a 73 911T.

Thanks

There is a number on the fan shroud
901 106 101 5R. not that this means anything...

your engine is listed as a 1973 911"T" engine with the CIS injection.

Where do you find such info???

There is also a number that will be like 911/57 ........If you are looking at motor and facing the fan.....on your right side down on the case ...a few inches away from fan shroud on a little flat piece a few inches to the right of the shroud you will find this number stamped into the case.....I dont think it is raised.....it is stamped into it.......You will need a rag and maybe something to spray in that area to clean it off so you can find it.......just clean real good on the lip on case next to the shround and you will find it.......took me awhile not knowing were it was......

you can find engine info and stuff in:
porsche 911(the original) by Peter morgan
isbn 90 389 03146

A good, inexpensive source (some of the very best) of such information and much, much more ... is the '72-73 'Technical Specifications' book from Porsche, pub. no 4220.20 ... available from many online sources.

not sure said: "There is a number on the shroud 901 106 101 5R. not that this means anything...."

What does that number mean?

I haven't located any references to the shroud numbers?

Me, either. I don't think the casting numbers relect the entire, actual part number, but, maybe the revision to the molds or machining process. The part number from my parts catalogue ... is 901.106.011.00 ... for the fan housing.

Would be a US/Canada 911 TE, 140 hp, 2341 cam, and the engine type should be a 911.51, which indicates it was originally in a car (probably yours) with a 4 or 5 speed manual transmission.

At least, that's if I'm reading the information at the Porsche web site correctly. Go to:

For the real engine number dweebs, you can also check to see if the crankcase halves match!

To do this, you'll have to wait until engine rebuild time, or at least, when you have the induction system/alternator/cooling shroud off the engine...

Assuming you are down to the bare top of the engine case, look carefully at the top centre of the case, where a couple of the outer case bolts are. Scrape away the oily grime and you'll see a three digit number on each case half.

If the numbers match, then the left hand case half "belongs" to the right hand case half...

This information may be useful if you are ever considering buying a used engine block.

Critical information, I'm sure! Do you think it would be worth splitting the case to check for this? I've got a few spare hours this evening.........

Just joking, but this BBS teaches me several new things every day.

Of a more serious nature: Big D advocates using a rag to clean the area around the engine number to see it more easily. Surely any 911 owner who lets their mills get that messy should be arrested by the Magnesium Squad, and held accountable for their heinous act of neglect in the face of engineering purity........

'72 911 TE

I find this post very interesting. My engine, which is in the process of being rebuilt has the # *6135141* and 911/91 with a chassis # of 9113111723 The car is a 1973 Targa. During the rebuild of the car I have found many things that have been changed by the PO. EG. It has a 915 tranny, I believe it also had A/C and it has Webbers that I don't think it was born with. Can anyone tell me what the car was originally? Looking at the Porsche site it suggests that it is a 911TK .. What does the "K" signify?

Thanks in advance, Paul

Matt, you made me chuckle, but you don't actually NEED to split the case to see these numbers - they are on the top flange, one (obviously) on each side...

It should be the work of minutes to simply remove the induction system, fanbelt, fan, alternator, plug wires, fuel lines, and various other lines before you can take off the cooling shroud and viola! The case side numbers are exposed (probably beneath a thick layer of oily dirt). Start as soon as you get home and you'll have plenty of time to see tonight's "Survivor" and "Big Brother" double bill...

Paul - I *think* the "K" stands for "Continuous" as in CIS, as in a 1973 1/2 911T fitted with Bosch K-Jetronic or "Continous Injection System."

BUT! I'm going from memory here - I'd need the (excellent) technical specifications booklet to make sure.
