Default What's the difference 1974 911 v 1974 Carrera?

Can someone help me understand the difference in the two (1974 911 and the 1974 Carrera)? Thanks

Rear fender flairs, ducktail, Carrera script, S front calipers, Fuchs with centers finished in same color as script. I know of a nice 74 Carrera with 42k miles for just over $10k in Denver. A similar 73 would be 8-10 times as expensive...

Don't forget that the "stock" 911 in 1974 came with 150 horses under the hood. The 911S and 911 Carrera came with 175 horses, principle difference was engine compression.

And if you're really interested, check out Bruce Anderson's "911 Performance Handbook" for more details.

Grant... what color is the Denver Carrera? I sold my Ducktail look-a-like last December and can't bear to pull its picture off of my desktop (check out the What's Your Car's Name thread (https://rennlist.com/forums/showthre...threadid=82528) in the General discussion forum to see a picture. It wasn't a real Carrera, but it sure looked like it (and had only 42000 real miles on it when I bought it in 1998!). Lord, I miss that car!

Thanks for the information. I plan to buy the Performance book today and do a little research. I thought that the compression was the same in the "911s" and the "Carrera" I had also thought that the "911s" had 165hp or 175hp and the "Carrera" had 210hp. What would be the difference if the compression is the same? Maybe the aspiration and cams?Is there any information that I can get my hands on from Porsche?

Hi Eric:

I suppose I should comment here since I still own a '74 Carrera that I bought new,......

Regarding USA '74 Carrera's,....the 911S and Carrera share the same CIS-injected engine rated at 175 HP. These have no smog equipment and differ from the 911 150 HP engine with different heads, cams, intake manifolds, pistons, and fuel distributor.

The Euro '74 Carrera had the same MFI-equipped 210 HP engine as the '73 Carrera RS.

FWIW, '73 RS Touring models weigh about the same as a like-equipped '74 Carrera,....

Hope this helps,

Boy, Steve, you really know how to get the jealous genes going! So what color is your '74?

As I said, I really miss my 911. It wasn't an S or Carrera, but it looked like a Carrera (I had the steel flares installed and bought Fuchs 7's&8's among other things). And even with a measly 150 HP, it was a LOT of fun to drive. I guess we all remember our first Porsches with fond memories.

Hi Toby:

Its black with a black interior. I've enjoyed the car so much that I've not been tempted to sell it, even when I owned a '73 RS Lightweight at the same time.

The '74 is now thoroughly "tweaked" for greater entertainment,....

Steve, If we're not being too nosey, how about telling us some more about your car.

Thanks for all of the information! I too own a '74 911. While it's not a Carrera, or even an S, it is still a blast to drive. The reason why I asked this question was to see how hard it would be to get my 911 to Carrera spec's or atleast more Hp. I am the third owner of this car, and the first male owner.

Aroq,

I recently bought a 74 911 that had the following done to it:

SC Flares, Carrera script, H4s, S Alloy calipers, 7 & 8 15" black centered Fuchs.

The PO had taken the 2.7 case and dropped in a set of 2.7 RS 9.8:1 pistons and barrels and a Bosche MFI from a '73. It has S cams. The headers are also from a '73. Basically it's a RS clone engine. I don't know about the HP (possibly 210) but the car pulls like heck. I'm very impressed with the flexibility of the engine as it is not peaky at all. It has great low down torque.

It's still a work in process. I have a ducktail and new IROC front and rear bumpers that are going on it due to the front spoiler mount oil cooler that I'm fitting. The amazing thing is how much $$ you can spend restoring the car. A few seals here, interior parts there, etc. and you're in for $6k!

I wanted the lightweight body with decent HP for track use and I think I got it. It's a joy to drive.

Nice Picture! Is that the sport muffler, I was curious if the sound is similar to the stock muffler? I don't know if you did it yourself or the PO did it. You're right about the $$$, I don't even want to know what I will be spending on the engine.

Lefty:

Pssst,......VERY nice car but,.......Its lowered too far in the rear,.....

You have insufficient suspension travel back there and when it bottoms in a corner, the spring rate leaps to infinity and then you are driving a park bench.

Let me know if you need help with the suspension; it looks like you did everything else right on target,...

Eric,

That sport muffler is a PO job. I think what he did was gut a regular muffler and weld on the two pipes. At least that's what I think. It's LOUD! But I think it sounds quite good and aggressive.

There's a drawback though. The tail creates a massive vortex which dumps exhaust gases (and fuel/oil) on the rear end. MY car is very rich at the moment and I have to constantly clean it at the rear. What would be nice would be two outlets at each corner. More welding to come!

Steve,

Thanks for pointing that out. I had just replaced the torsion bars and rolled the car out the garage to take the pic. You know how difficult it is to get it perfect first time! I have the car at my mechanic getting aligned and lowered correctly. It's pretty stiff so there's not too much travel back there but you're right it is too low. The front needs to be tucked in with rolled fenders. I think you may have noticed it has 944T Fuchs 23.3 offset so I'm running 225 up front but it's still a squeeze!
