real 2.7 MFI or not ??
 

Hi all

I need an urgent help : may somebody tell me the parts to check to be sure i'm buying a 2.7 rs MFI engine,

the seller gave me numbers that match nothing ??

I know what it looks like but not accurately enough :confused:

This is to become a child dream for me

the engine 's been rebuilt 10 000kms ago, the man have the papers, but are there numbers anywhere, special parts, identification signs ?

is there a noticable difference between a 2.4 MFI and a 2.7 carrera MFI ?
and my last question : may you confirm to me the 2.7 RS engines (73) and 2.7 euro carrera (74,75,76) where exactly the same ?

I'm waiting for your grateful help

Best regards
Philippe

The number on the case should be 911/83 for the '73 and also the Euro '74 and '75 Carrera RS engines.

thanks but
 

any another precious advice ?

please, please

The serial numbers for the '73 RS engines should be 663XXXX. The '74 RS engine should be 664XXXX, and the '75 RS engine would be 665XXXX. There were a limited number of '76 RS engines and those I assume would be 666XXXX. All the RS engines (911/83) are the same no matter what year car it is in. Hope this helps.

nobody for my 2.7 MFI ??
 

No MFI 2.7 engine specialist on this board ?

They have given you what you need. The numbers tell the story i.e. 911/83. Other than that a 2.7rs and a 2.4s motor look identical.

Re: real 2.7 MFI or not ??
 

So what are the numbers he gave you?

you need:

the engine type 911/83
engine serial number 663... 664.... 665....
and the mfi pump type number, i don't have but i can try to find

i think those are all the numbers you can get. For anything else, you will have to take things apart.

73 RS / 74 Euro Carrera MFI pump:

porsche # 911 110 254 00
bosch # 0408 126 019

source: check, measure, adjust

many thanks
