Post a pic of the underside of the engine, when you can, so we can see if the rectors are there. Their removal should be your first modification, if your smog police allow it.

Have not read the above but there are some special things about the 75.

It has lower rear ratio. Mag trans and motor case which is much lighter. Aloy rear arms and front cross member.

Many have Aloy front calipers. Many still have 6x15 Fuch rims which are valuable.

I have seen several that the owner went through as a labor of love. They can be very capable track cars as they are pretty light.

Adding SSI or headers and a sport muffler makes a big difference. Conversion to carbs makes for a responsive vintage experience.

The S has big 36mm ports that do not need to be opened up to make power.

With carbs, headers, sport muffler, modest weigh reduction, and other basic improvements can equal a 73RS's performance potential.

Having said all that, the mag case motor can be expensive to rebuild. If done right and there is a good oil cooling strategy is in place, they can last for ever.

I would avoid any 2.7 that has not been well maintained.

I was attracted to the '77 for a few different reasons: I had a '69T before with a 3.0 which I loved and regrettably sold. To me the middies have some of the qualities of the longhoods (lightness and simplicity) without the rust issues and big prices. The middies are just slightly heavier than the longhoods but the bodies are also stronger and more rigid. My '77 has a rust-free galvanized body, decent brakes with a booster, aluminum rear control arms, a 915 tranny; just a few improvements on the earlier cars. The 3.2 solves all the issues of the 2.7 and makes for a reliable, economical and powerful motor. Plus middies are different! (I'm funny that way). So can anyone tell me what's wrong with a good middie BESIDES the well known motor issues? Also........if you want an inexpensive 911 to tweak/modify/build/learn on etc. you won't feel like you are commiting sacrelidge if you alter it or make a race car out of it. The narrow body is also a matter of taste. Personally, I like the slim look with a set of sevens tucked under the wheel arches. Very "old school". A middie is like the plain looking girl you knew in high school that was really fun in bed! Then when you saw her at the reunion she looked better than ever. Fast forward ten years and I think people will look at the middies differently. Just my (biased) opinion. Enjoy your new car!

pics please!

911st I am under the impresion they all had 8.31 final drive that year,,,,,,mine does

here's a couple pics with the 16x6 fuchs. The sevens go on next week. The 3.2 is stock and will get a SW chip and cat bypass later.http://forums.pelicanparts.com/uploa...1228331802.jpg

Thanks TT - looks great. Good inspiration.

My 75 Carrera, agree with all that has been said regarding the engine. All updates plus SSI's and no smog.

Here's the underside.....as a 911 newbie I have no idea if the reactors are there or not, please advise.

Thanks,

Nope, you are good to go, someone has plugged the air injection as well.

Com'on middie owners this video is awful! That guy doesn’t know anything. I don’t know anything. The "70's tweedy replacement interior" looks like factory 25 aniv interior to me, but it’s hard to tell for sure with the grainy vid. He knows the market so well to underestimate the final bid by 47%. I also noticed 3 other blatant errors. I am surprised no one else has pointed this out.

Sorry to be off point but that video has bothered me since the first time I saw it and it wasn't just because it hits so close to home.

And yes I think middies are great cars when all the homework is done.

I totally agree......that guy seemed like a tool. He came across as an insufferable know-it-all and poo-poo'd everything about that car without really knowing its history. He was just regurgitating a few tid-bits he had heard about problems on midyear 911's and using those things to condemn that car along with the entire midyear run.

Anybody know who he is ? Sure was a Bias A.H. Some of what he said would have been true in stock form, Maybe it all had been addressed ??!!
What a turd

The guy talking about the Porsche was Rob Sass. I’m impressed with anyone knowing as much as he does about mid-year Porsche’s. Even several poster on this blog don’t know all the ins and outs of a mid-year. The problems keep coming up on threads – so it’s pretty obvious that not everyone knows the mid-years all that well. Let’s take a look at Rob’s comments, and you tell me where it gets it all wrong:

Quote:

This is a good example of how not to buy a 911

– I think he’s right. I’d never buy a Porsche at an auction – the cars are overrated, and over priced.

Quote:

This is a 1975

– well yes, that’s correct

Quote:

This is the probably one of the worst years of the 911 that Porsche ever made

– unfortunate, but true. Are there any years that are thought of less than the mid-years?

Quote:

There are issues with the emission controls making a lot of heat

– yes that is exactly the problem, well done Rob.

Quote:

The cylinder head studs actually pulling out of the engine

– right again! A lot of people here still think the head studs break, but that was on later versions. It’s the pulling out of the block that is the real 2.7 issue.

Quote:

They are notorious for the 2.7 being nothing but trouble.

– OK, here he goes a little far, and is generalizing – but still, you have to admit, that the 2.7 is thought of as trouble.

Quote:

Looking at the engine compartment, it looks like its had no attention there

– well, we don’t get to see the engine compartment, but I’ll take his word for it as he has gotten everything else right so far.

Quote:

The car exhibits good symmetry, it’s been smacked on both sides in almost the same place.

– again, we can’t see this, so we have to take his word.

Quote:

There’s a crease on the door and front fender in the same place, and rust through the bottom of the corner of the door skin.

– again, would anyone buy this car in this condition? Not worth the trouble to fix these issues on a mid-year. There are better, cheaper examples out there.

Quote:

It has European H4 headlights

– Rob knows this area better than I do, so I believe what he says.

Quote:

The interior looks like 1970’s tweaty fabric that is completely wrong

– we can’t see the interior very well, and it looks like some kind of recovered seat material in velour. Sorry, but it does look nasty.

Quote:

This is definitely a U.S. spec car with the large rear bumperettes, which would be ½ the size on a European car.

Again he gets it correct. We see these questions come up all the time here on Pelican, so not everyone knows this.

Quote:

By 1975, with the emission controls on these cars the “S” really didn’t mean the same thing it did in 72 or 73. The “S” produced about 160 hp, and about 148 hp in the base model.

How many of us could rattle off the difference in hp for the mid-years?

Quote:

Not among the fastest 911 ever made.

Yes, that’s true.

Quote:

I would stop bidding at $5000.

That price seems about right to me, but I wouldn’t buy it even for that.

So even though Rob’s attitude makes it seem like all mid-years are junk, I think you have to give him credit for knowing more than most about the mid-years and their issues.

Attention, the 2.7 series was so bad that after 33 years they have been long gone from the scene. Any remaining 2.7's obviously could not exist. Don't believe your eyes if you see what looks like a Porsche 911. As all the detractors of 2.7's have told us they are really bad cars, therefore they could not have possibly survived. That 2.7 that just passed you was a mirage.

That's exactly the route I went......and I'm lovin' it!! What a blast to drive. The 3.2 (with cat bypass & SW chip) just lights up that mid-year chassis. I've had an 80 SC and an '89 Carrera which were both nice performers, but my '77 3.2 is noticeably faster than either.....and more fun to drive in my opinion.

Hey, I driven that car! :D I'd have to agree, the 3.2 is really good for a middie! Now where did I put that seven thousand dollars... :p

Just wanted to say congrats on the purchase and welcome to middie ownership. One way or another, I'm sure it'll be an adventure!

Here's my '74

I 100% agree. After all, all a 2.7 L engine is good for is to hot rod a 914 (thanks JP)

It was run for 6+years at Autocross (2 drivers 2or 3 events monthly) before rebuild. Newer missed a start. Always in the top 5 for TTOD.

Well I'm into my first Porsche 911S and it's a 1977. It's all original except for the necessary engine upgrade repairs, pop-off valve, and now I'm thinking of removing the basics of the a.c. But I love this car and I guess I'm going to learn as I go. I bought it from a person who knows Porsches and maintained the car really well. So I didn't buy this car expecting a Honda. I bought it expecting fun and to spend some time wrenching on it and taking care of it. I think it will be fun and of course I love driving it but sadly now it's time to put her away for the winter.

I have a 75 S. they are beautiful cars. I have done all the needed things and then some.

It's a car, man. Enjoy it, have some fun.

Here are a few pictures of a 75 S.
