1976 carrera

[TERRIBLEHONDO]

I know this might be a stupid question. But I see some conflicting information. Was a 1976 carrera made? What size engines did they come with a 2.7 or 3.0? Or do they come with either type? If it did come with a 3.0 is it the same as the 3.0 in my SC. Thanks hopefully you guys with more experience can help me out.

As far as I understand, the Carrera from 75-76 had the 3.0 L engine. Basically the same as the later SC.

I might be wrong though..

2.7 in US

[TRE Cup]

but a 76 carrera in the usa was not available.

as a euro/ ROW model it was available with either the 3.0 small flywheel end motor or the 2.7 mfi 911/83 RS engine.

The usa carrera was the turbo carrera in 1976= different kettle of fish

[klaucke]

Although both 3.0L and both using CIS induction, there were many differences b/w the Carrera 3.0 motor and SC 3.0 motor. Perhaps the biggest difference is the earlier style crankshaft (same as 2.7) that takes a 6 bolt flywheel. The SC uses the later 9 bolt flywheel. The bearing are different sizes and the cranks are not interchangeable. It is purported that the C3 motor is livelier and revs quicker, due to less rotating mass.

Also, the Carrera 3.0 was rated at 200 DIN HP, 20 more than the early 911SC's.

If my memory serves me correctly, early in the 1976 model year there were some "regular" 2.7 liter Euro Carreras built with the 911/83 210 HP engine.

My understanding was the following:
74' and 75' had the MFI 2.7 Carrera with the short hood. In 75', there was a US Carrera which was a dressed up 911S.

76' and 77' was that the Carrera 3.0 was sold in not in the US. It was basically a CIS normally asperated (higher CR and differnt heads) version of the Turbo Carrera which had the same crank as the 2.7L but the stronger Al case.

78' came the SCs and the 3.3L turbo with the larger crank.

there were 2 versions of Carrera offered in MY76, not counting the turbo Carrera
Both were RoW versions;
911.83 - MFI, 2.7, 210hp, 8.5cr
930.02 - CIS, 3.0, 200hp, 8.5cr

The 911.83 was first offered in the '73 Carrera 2.7RS as a long hood and was continued as an offering in MY74-76 w/ the short hood bodies

The 930.02 was the first street n/a use of the aluminum block and was a RoW MY76 & 77 offering only.

The '76 & 77 Carrera 3.0 morphed into the MY78 SC

the 930.02 used the 2.7crank, when the SC came out it used the beefier turbo crank but w/ smaller rod journals.

the 911SC 930.03/13/04/05/15/06/07/08/16/17 had the same8.5cr, heads and cams as the C3 but was rated at 180hp because of tuning

the 911SC 930.09/19 used in Row SC were rated at 188hp, again mechanically the same as the US/Cdn/J versions just different tuneing.

OK guys thanks so if I understand it. There is no US version of a Carrera in 1976 only ROW. If someone has a Carrera here it was an import or home built. The ROW had 2.7 MFI and a 3.0 CIS and a regular 911 here had the 2.7 CIS. Is there a way of telling a 2.7 case from a 3.0 case visually or do you need to use the engine numbers? Thanks for any help.

The 2.7 has a mg. case w/ 911 part #(901 casting # is what is visable on the side of the case), the 3.0 has an al. case w/ 930 part#(and a 930. casting #)

At least most 2.7 had a mg. case there were a very, very few al. case 2.7

here is 1 w/ a 901. casting # visable

Thanks for the info I did not even know that the 2.7 could come with an aluminum case. I will just check engine numbers on the case.

Bill, will you be my personal Porsche expert? I will pay you nothing but sincere gratitude.

Check the VIN, too. Pretty easy to tell from that.

VIN, engine number or just put your foot down in fourth gear, no doubt about what is in the back when it starts picking up at 3700 revs

As Bill V. said, an aluminum 7R case is very rare. I believe the only picture I've ever seen of one from taken by Steve Weiner. It would not have been on any late production 2.7, rather, it was almost assuredly a racing part. There's a good thread detailing Mg, Al, and Siluminum 7R cases on the Early S Registry.

does anyone know what cam towers, cams and heads the 3.0 carrera used? different than the SC?

All the same as early SC

Cam timing was changed back and forth a few times between '76 & 89
