Modern horsepower, brakes, and suspension to all work in unison in the old '78 Targa package.

...it's called a Singer...

An early 911 with a big motor and a PDK/launch control would be pretty cool.

I have spent the last few years moving my ‘84 back to the ‘60s. A/C gone, suspension upgraded, all unnecessary stuff gone, heater backdate w/SSIs. If I wanted all the modern stuff, I would buy a modern car. Adding that crap is like:

Pretty sure there are airbags there too....

To each his own. It is your car, do whatever you want to it.

I live in an area that gets hot and I drive my car to even hotter areas. AC is not just nice, it is a necessity when the heat index is 125.

Blame Ernst Fuhrmann. For whatever reason he hated the 911, and wanted it killed off and replaced with the 928. He forbade ANY money to be spent on R&D for the 911, and any improvements.

Then the American Peter Schutz was hired as the president and CEO of Porsche. On one of his first meeting with the staff, he drew a new time line for the 911. It went all the way around the room. From 1981 on the 911 evolved slowly until he authorized the 964 major redesign.

Without Peter Schutz, the 911 would have died in the 1980s. Thank you Peter Schutz!!

You can put in a modern fuse box yourself for less than $100. There are some great kits out there too, for a bit more. I ended up doing this after the 3rd time I got stranded with corroded fuse contacts.

The modern upgrade I'd like on my SC would be back seats that better fit child seats, and shoulder belts in the back. Not what I would have said 5 years ago...

I did this myself with a little work. But then the dash lights still stayed on and ran down my battery. Now I have one of my wife's hair ties on my keychain, and hook it on the lights switch when I turn them on. Now I can't remove the key without unhooking it from the lights switch and remembering to turn it off.

Agree 100%. A friend of mine restores English cars and can get brand new complete plug and play wiring harnesses for MGs and Minis for under $300. The same for a Porsche would be several thousands of dollars, custom made, with a lead time. It's pretty ridiculous.

Not sure I'm buying that, that sounds like the speach from his daughter selling books on how great her dad was and American rah rah rah propaganda. . With all due respect thats not how it went down.

the 911 was never supposed to exist beyond 1977 with the 928 and other water cooled cars taking over in 1978. This was 3 years before Schultz was at the helm of the company.
A small development budget was given to the 911 engineering dept to rectify some of the issues seen with the disastrous ( even then ) 911s. to bridge to the 92X series.
So they went about fixing the case, improving the cooling , converting to electronic ignition, added the WUR to the engine. Updated the styling and ultimately produced one of the most bulletproof cars ever designed by Porsche up to that point. It proved immensely popular and set the future for the 911.
Although Schultz could have killed off the 911 at any time once he got to power, he can hardly be credited with " saving " it.

If you don't have caveman carbs on there, then yer just posin' 60s, bub! :)

Says, the guy who specializes in blowing hot air.....
I wanted all the best of the 60s, not the worst....

A real, no frills vintage car enthusiast, that celebrates swamp-ass motoring, should enjoy the tinkering and tuning of carbs and embrace the glory of hard cold starts, horrendous fuel mileage, ridiculously rich mid-range AFRs, and the ever present, strong aroma of fuel!

Back when he was still the big boss, he attended our War Bonnet Tech session in Oklahoma City and he was the keynote speaker one evening. I personally heard him tell the story.

We used to get fantastic factory support. They gave us one of the connecting rods from the race car that won Le Mans to give away as a door prize.

I sat an slammed beers in the hotel bar with Hans Mezger the man that designed the flat 6 Porsche engine. I learned to never try to keep up with a German drinking beer. He looked fine and I could hardly walk.

The factory shipped up an entire F1 Tag Turbo engine, but they wanted it back. I have parts of the rear suspension of the 993 in my garage now, a complete hub and a engine cross member.

So I was there, and heard it myself from the big man.

Been down the road of too far. I built my 1974 Toyota FJ40 Landcruiser into the thing I wanted. Swapped a Toyota 3B diesel in, decided it was painfully slow, grafted a Toyota Supra turbo onto the mess, pushing 20psi of boost at 2500 RPM, the trans was swapped out for a 5 speed and installed the parking brake on the transfer so I could install discs all around, then I decided that it needed power steering for the crawling/climbing. I then decided that the 33x 12 BFGs needed to share the work, so I installed front and rear Detroit Lockers. Then I decided that I needed more articulation, custom springs. Add custom home built front and rear bumpers, PTO winch. Now it will spin all 4 tires on granite, and is so softly sprung it’s a nightmare on the street, but it will go up stuff that you don’t want to go down. Too much isn’t enough, just enough for the mission is the new motto.
If you want to waste some time, here’s the FJ40 Mutation:

Mine would be a dynamic exhaust mode so I could hear... anything really... while highway cruising and then listen to sweet dual exhaust music while thrashing the twisties.

The 7 speed manual from a new Carrera would be sweet..

Good AC!!!! I've thrown everything I can to upgrade my '88's AC and it's STILL anemic. Clearly I've done something wrong since Ronnie and Glen (and many others) have similar setups and their AC freezes their A$$ off.
Other than that not a whole lot I'd change...in reading many of these posts I think a 996 or newer 911 might solve some problems. The friends I've had who moved on to "newer" 911s (water cooled) have been very happy with them. Except in the case when the IMS grenaded...LOL, but even that is an easy fix now thanks to Jake Raby.

What upgrades have you done?

I have basically all the bells and whistles from Griffiths for my model. 4 condensers, all new hoses, his upgraded evaporator, bigger fan mother for more air, and the variable speed fan switch. The same OEM Nippindenso compressor, and since my car is a n 85 with tiny dash vents, I have his vents on the knee board and the center vent. I get air temps in the 38 to 40 degree range at max blow with the thermometer on one of the side vents when driving in 90 and 100 degree heat.

Call Charlie, tell him what you have, and he can design the system to fit your needs. It is not an inexpensive fix, but I did my system 11 years ago. It is just simply the best upgrade I have done to the 911. I can drive on HOT days and be totally comfortable. And my wife will ride with me happily in the summer.

^ What Glen said. If you want what any of us would consider "modern A/C," get the full Griffiths kit.

Buck has almost the same, home built system as I do (similar to Griff's, but components from various suppliers); he should have high 20s vent temps in high 90s ambient, but doesn't have anything close to that. It is a real mystery (all troubleshooting basis covered in the forum over the past two years or so - including lots of input from Griff).

I updated my 911SC, everything modern from the navigation system to the A/C. Xenon headlights and 300hp. Here's what it looks like now:

Yes that's a joke, but really, if you want modern comfort the 996 is a LOT of car for the money.


I can help you with that. We developed an active exhaust system for the SC/Carrera.

Ronnie is right, I have a new compressor, new evaporator from Rennaire, 100% new hoses and fittings, new/additional condenser with powerful fan. original condensers flushed with appropriate cleaner. Have vucuumed down and recharged several times, including taking it to a "professional" AC shop to see if I was doing something wrong....still get, at best, 30 degree drop from ambient at the vents. So, if it's 95 I'll see 65 at the vents. As unlikely as it seems I am wondering if there is anything wrong or out of adjustment with the Rennaire evaporator. Yes, reciever drier new every time. Charlie has suggested there is most likely ambient air in the system but I'm not sure how that could be considering how many times it's been evacuated and recharged. I'm pretty much given up and just drive the GLC 300 99% of the time. Sorry, did not mean to turn this into an ac thread.

Here is my bucket list of things I would do to upgrade/modernize my SC, if I had unlimited time and budget:

- Porsche classic navigation system/radio
- Modern EFI with PMO ITBs
- Led lights all around, inside and out.
- A faster gearbox, like one form a honda.

All I really wish were that long hoods were galvanized, if so I would still have one to go with my 993 and 991.2 GT3T. Newer engine technology would be nice too. The 993 is too heavy (it is a C4 cab with power seats) and underpowered, and the GT3T is too heavy and too big. However, not having serious corrosion concerns and having 273 dead reliable air cooled hp and a nice 6 speed :), (let alone the GT3 drivetrain which is sublime) in a lightweight beautiful long hood would be excellent. Probably why singers sell for what they do and why backdates are so popular generally.

Two schools of thought on modernizing the 911:

1. Electrification: Make it fast, reliable, clean, and future-proof. Porsche has always been more about the chassis than the drivetrain. Don't think for a minute that Ferry wouldn't have used the Tesla drivetrain if he had access to it in the '60's.

2. Get off my lawn, Millenial!

Charlie knows way more than I do. My way to vacuum the system is one that assumes some moisture in the system just freezes into ice, and sorta "hides" inside. Ice is slow to sublimate. To finally get a rock solid vacuum, I bought a small tank of dry nitrogen, and a regulator setup. I pull a vacuum for several hours, then refill the system with only the dry nitrogen, and even pressurize the system to 150 PSI and let that sit to look for any leaks using soapy water on connections.

Pull another two or three hour vacuum, refill with nitrogen, and let that sit overnight. Then pull another 3 three our vacuum, using fresh oil in the compressor, and then purging every line and connection of the manifold with little refrigerant to be 100% sure there is no air left, recharge the system. I am too chicken to use the liquid refrigerant so I do it all with just the gas, through the low side of course.

It is a belts, suspenders, and still holding on to my belt loops method of recharging.

One other very important item. Double check the evaporator sensor location. I just upgraded my fan motor to the big fan, and had the top of the fan cover off. When I put the sensor back in, I was careful to place it properly, and I used a little dab of thermal paste on the brass tube, and the bulb of the sensor. That really seems to get the temp lower and avoid any freeze up. Before I would get evaporator freeze up if I ran the system on max cold for an hour or two. Now it just cycles off the compressor as needed.

I am driving my 911 to Key West next month. July in Key West is gonna be HOT. And I will have my brother with me, so maximum AC will be needed. I will report back on how it did after the trip.

Plus one ! It is only June and already we are mid 90s and 98 percent humidity. Misery.

Maybe update the front suspension to make it handle like the newer water cooled 996's and get rid of that horrendous understeer.

Cheers,

This will probably be a stupid question but how do I get fresh air?

Anyway, at this point I'd be happy with a windshield washer system that works as well as a full syncromesh transmission.

PDK with luanch control on one of my 993's would be pretty sweet

Moved the top lever on the dash sliders. The top lever goes from closed to open an no fan, then 1,2 or 3 on the fan speed. The second lever is left to blow on your feet, right to blow on the windshield, in the middle is a blend from feet or defrost. Nothing will ever blow on you face if you don’t have AC.

This story is pretty well told so I don't think anyone should doubt the veracity.

Not sure if Fuhrmann wanted to kill it. He probably wanted to stick to the plan of 924/928. The SC was supposed to be the last of the series, like the 356SC.

The mid-year foibles seem bad in hindsight but they were nothing compared to the competitions malaise era cars of the day, of which few actually survive. Compared to a 'muscle' car like a trans am or camaro, or even a mid engined exotic, the 911 of the mid '70s was a rocketship built from granite.

But Schutz didn't save it. The buyers did, because they walked straight past the transaxle cars and kept buying the 911 at something like 2x the rate of the 928. Schutz merely recognised the fact that the customer is always right. The development money only went into the convertible and then the new engine. The 928 lived for another 12 years after that.

Ironic, because the 928 has got great AC, is quiet and comfortable while still plenty fast, plenty of space, 'modern' handling....but nobody has yet suggested trading the 911 for a 928!

I've tried that and I get a lot of noise and a faint breeze.

So I'm going to change my answer above. Like a modern car, I'd change my 911 so fresh air blows on my face from the center vents.

In Schutz's speech he said his predecessor just wanted the 911 gone, but it was still selling well and it could not be just dropped. Fuhrmann forbade any and all R&D money for the 911. Schutz reversed that, and gave them a budget to improve the model. The fastest way to kill a car, is do not let it improve. Keep it static as the competition improves. The Model T was mostly unchanged for years, but that was a very different era.

Different thing. Yep the factory designed fresh air is a total joke. You need an AC system to get air on your face. There are mods and lots of threads on this site on how to change your fresh air system to blow through the center vents, but it will still suck with that little fan. AC is your best bet.

Yep, and in fact, I made mine completely inop by making a blocking plate out of thin metal and installing that under the intake screen (completely unnoticeable when painted flat black) - really cut down on the amount of nasty, Texass air that enters the cabin at highway speeds (only supercooled air for me - none of that hot, humid, gross stuff needed)!

Yes. Understood. I've owned my 86 for almost 10 years and the AC belt has never been on it. I suppose I should get it going (I even have a tank of R12) but where I am, it's rare that I actually need it.

Parts availability like a new car. It sucks paying $25 USD for shipping for every little thing.

That is when it comes down to your decision making. Even with no compressor, you can run the AC evaporator motor and blow cabin temp air on you. That helps if you are already sweaty. At autocrosses I use a switch I installed to kill the compressor, and I run the evaporator fan to blow on me.

Open the fresh air and divert it to the floor, and run the AC fan at max, and you get some air blowing on you and that does help me.

To replace your AC hoses, new dryer, and new compressor and likely replace the evaporator would get you fairly stock AC. It is lots better than none. Talk to Charlie, tell him what you have, and where you want to go. It is far from cheap, but he makes a great product.

For me, it was without a doubt the best improvement ever for my 911, and I have done many improvements.

It is your car, drive it and enjoy it. If you find yourself not driving it becasue it is hot outside, fix that issue, and get to driving!

Lots of AC in this thread, The Classic Retrofit is a great kit.
