2.7 carrera engine

[philippeF]

Hi

I'm on the way to buy a 72 S
The seller tells me he's made an upgrade : 2.4 to 2.7 carrera engine

May you give me the 2.7 carrera engine numbers if possible

or tell me the difference that can be seen from the outside to check if it's a 2.4 S or a 2.7 carrera engine

many thanks

best regards

Philippe

2.7 Carrera (RS) MFI engines are designated 911/83. They have a red shroud, too.

Sounds like it could be good fun!

From Page 201 of the Engine Rebuild Book:

SN starting with 613 3001 for 1973
SN starting with 665 0001 for 1974/75

Engine type 911/83.

Hi

i've tried to translate "shroud", but the result means nothing to me

any suggestion ?

[k9handler]

the part that covers the engine top behind the fan...that is the shroud.

Wayne,

The serial # for the 911/83 engine in my '74 Carrera 2.7 is 6641184.

What's with that?

That looks correct to me Matt.

6 (six cylinder), 6 (carrera), 4 (1974) 1184 (seq.#)

665xxxx would be a 75' Carrera motor.

663xxxx should be a 73' Carrera motor.

The number 6133001 that Wayne shows would be a 73' T CIS motor.

Also Phillipe. Sometimes when people say they upgraded to a Carrera motor they mean that they took their current motor and rebuilt it to Carrera specs. If that's the case then the motor would have a serial number like 632xxxx. Meaning a 72' S motor. The type number would be 911/53.

Lifting the engine lid the motors look identical. Looking underneath the car the cylinders would look larger on the Carrera motor. Numbers, however, are the best way to tell.

Bobby,

Thanks for putting my mind at ease!
