Pre-purchase question/engine & vin numbers

[geshaghi]

I'm looking at a 1972 911T for sale. The car needs restoration, but appears to have good bones. The seller indicates that the car is numbers matching (i.e., original engine & transmission) but doesn't have a COA. Is there a way for me to confirm that the engine is original to the car without a COA? Are there any online resources that will help me decode the VIN and engine numbers? Thanks

:welcome:

Post the engine and chassis numbers here and we will see what model year and engine group they are from - but the only 100% confirmation is a COA from Porsche.

I would like to know a little more about this

engine code. This should be a 930 motor

and I think it is a 3 liter.

930 101 104 5R

Thanks for any information.

That is not an engine code - looks like part of a part number.

A 930 engine code looks like 930.60 (which is a 3.3 liter 1981 engine).

[PAULSPEED]

This was the number I was given for the engine code. If

this is not the case part number, is there a place to find the

engine number on a 930 motor. Thanks again for your

help.

Paul

[Loren]

The engine code is not the engine serial number.

If you can get the engine serial number I can likely look up the engine info (model year would help trace it down faster too).

[PAULSPEED]

Where do you find the engine serial number on a 930 motor?

How many digits is the serial number?

Paul

[Loren]

The engine number is stamped on the left crankcase half, below the fan housing (arrow).

I got the number.

911 5 201 654

Can you tell me something about this motor?

Thanks,

You will likely have to have someone that knows that vintage motors have a look at it because it was very easy to mix and match parts. I think that number signifies a 1973 E case.

Here is a picture of the number. It looks like it has been

blasted.

Any ideas on where I could find someone who knows about vintage numbers?

Find anybody over 50 in the Porsche club. (I can say that because I am over 50 :lol: )

[PAULSPEED]

OK so am I. I looked for information on a 911 E

motor and this is what I found.

911E 2,4 Coupe´ 1972 - 73 6 - Zyl. Boxer

2341 cm³

4 - Gang 121 kW/165 PS

bei 4500 1/min

V-max: 220 km/h 2.470 9,5 s.

My friend bought the motor as a 3 liter. Lets

guess the motor was increased from a 2.4 to a 3.

What would happen if you made this motor a 3.6?

My guess is that there would be to much pressure on the

case to make this a 3.6.

Bruce knows these early cars inside and out.

This is real funny because my friend who own's

this motor wants to take Bill Anderson's course on

motor repair.

Looks like roseville to plymouth is 30 miles so that

makes you neighbors.

I have an e-mail into Bill.

Do you know of any other sites that go into

hotrodding Porsche motors?
