Thank you

It looks like that VIN would have engine numbers, 6129001-6129293. Tony.

I think those number ranges are for a sporto engine (911/61 engine type). The 2.4 liter 911T with MFI , engine type 911/51 will have engine number range 6120001 to 6124478.

vnm007,

You got TWO correct answers to your question.

9112110114 decodes as:
911 = Vehicle model (911 group).
2 = Model year 1972.
1 = Engine type 911T-E.
1 = Body version Targa
0144 = Sequential number.

The engine type 911T-E is the designation for 1972 or 1973, 911T, 2.4 l (2341 cc, 140 hp, MFI). The engines can be either type 911/51 for USA 4-speed or 5-speed equipped or type 911/61 for Sportomatic equipped.

If the engine is type 911/51 then the range of engine numbers are 6120001 to 6124478 (4478 total).
If the engine type is 911/61 then the range of engine numbers are 6129001 to 6129293 (293 total).

These engine numbers decode as:
6 = Engine designation, 6-cylinder unit.
1 = Engine type, 911T-E (1972 or 1973, 911T 2.4 l [2341 cc], 140 hp, MFI).
2 = Model year, 1972.
0, 1, 2, 3 or 4 for engine type 911/51 for manual transmission; 9 for engine type 911/61 for Sportomatic transmission.
xxx = sequential number.

The transmission types used with each engine type are:
For 911/51 are 915/00, 915/01, 915/02, 915/03, 915/10 and 915/12.
For 911/61 is 925/00.

Transmission numbers decode as:
7X2xxxx;
7 = Transmission for 6-cylinder.
X = 2 for 4-speed, 3 for 5-speed, 6 for Sportomatic 925/00.
2 = Model year 1972.
xxxx = Sequential number.

Hey Grady...is that a $1.25 answer or a $12.50 answer?

I'm looking at buying an engine and the seller just gave me the engine number as he's not sure if it's a 2.7 or 3.0...

OE 320146S

Does that mean anything?

Thanks guys

that's not a proper number. should be 7 digits...all numbers for a 2.7 or 3.0 up to 1981. For the 82 and 83 3.0's it was 8 didits... 2 numbers 1 letter and 5 more numbers.

Seems like you guys on this thread might know how to answer my question. Bought a 2002 C4S with a bad IMS bearing which F'ed up the engine. I brought it to a "rebuilder" and didn't write done engine number. I'm worried I may not get MY engine block back. My vehicle's VIN is WP0AA29942S623580 - Can someone tell me the Engine number range for it? Is there anyway to know if I got the "matching" engine block back? I don't know if the newer cars can be deciphered like you guys did with these older one.

Thanks!

Which brings us to the next mystery engine # from a 1973 1/2 T with VIN #9113112067 and engine # 6133169 type 911/91. PCA says it's not the correct eng. # I've been told but I can't confirm that because I'm in Puerto Rico and they won't give info out unless you have a stateside address/phone #. A friend of mine in the States actually got the info over the phone. I believe it is the correct # as there are so few of these out there. Any ideas? Thanks.

djpateman · 04-20-2012, 06:14 AM

type 911/91 starts at 6133001 <> 6136092
6133169 is # 169 out of 3092 thus very early
9113111001 9113112302
9113112067 is # 1067 out of 1302 thus very late
to match the engine should be in the 61354xx range

Thanks, that sheds some light on it. More research needed.

Grady Clay · 04-20-2012, 08:36 AM

smooth,

I find it offensive that PCNA doesn’t respect Puerto Rico as USA.
If you have a problem with them not responding, please tell me. I’ll make them understand.

Best,
Grady

The original engine to your vehicle should be:

M96/03 66223715

Original transmission number:

G9631 1007555

JRBennett - Thanks for the Info. I'll use that when I pick up my disassembled engine. I asked that he not put anything back together or crate anything so I can carefully inventory the parts. May I ask where you got the information?

Thanks again!
