I’m always amazed with Nathan and his never ending knowledge on all things Porsche.
Historical note - there is a theory on why the SCs were such good cars. Theory is that the engineers and assembly line workers thought they were building the last 911s and they wanted it to go out on a high note. Great video as usual from Nathan.
Great Video summary of the SC . It validates the 81 SC that I bought from the original Owner 35 years ago. I seem to fall into that small percentage of cars that are Original Paint and no accidents. Nathan is spot on. Grand Prix White exterior / Can Can Red leather seats / Full Leather interior. . Black Leather dash & trim / black rugs. Is a combo that really POPs . 41,000 miles with documented Speedo change by Dealer and all service documentation !
Thank you so much for bringing awareness to the amazing 911 SC. Overlooked and under-appreciated by the community
Learned a ton from the video. Appreciate the amount of time and effort that goes into these videos, thank you producing them - invaluable content.
Our pleasure!
Wooohoooo!! Finally! Just bought my 911SC a month ago, so wish I would have had this. Thank you Nathan & PCA!
Hope it helps with your ownership experience as well. Congrats on the new-to-you SC!
As always...we're not worthy. :) Thanks for the info session. I've already shared it with a friend who is in process of restoring an SC Targa.
Incredibly informative video!! I learned so much about the nuances of each car which informs the variances between cars even between the same model years!! The radio “misplacement” on delivery forcing dealer install is hilarious! I love my 88, but I’d definitely consider an SC. Thank you!
Glad you enjoyed it!
Thank you 🙏 great video by Nathan knowledge of all things 911
nice job ...SC are the perfect balance between vintage and sport car ..general clarification: All SCs have 49mm intake valves, and 41.5mm exhaust valves. The '78/79 cars have an intake port that's 5mm larger (39mm vs 34mm), but the exhaust ports on all SCs is the same (35mm). The early cars use larger diameter intake runners, but the '80-83 cars have a solid improvement in torque with the smaller runners and intake ports. All USA SCs are rated at the same HP (180 DIN). If a camshaft change is done care must be taken to not disrupt intake manifold vacuum. CIS injection depends on that vacuum to operate properly, which is why Porsche was so conservative with cam profiles for the CIS cars. Although all SC cams are similar, the late engines have a different timing spec, which must also be taken into account. Regarding compression, '80-83 cars have higher compression (9.3:1 vs 8.5:1), made possible by the more precise CIS which includes Lambda (oxy sensor, ECU, etc.).
Thanks for sharing this info!
Fantastic video you guys! Thanks again for all the hard work you put into making these!
Thanks for watching!
Nice production on this one
Hi Nathan, thank you very much for all that information and looking forward to more of your in depth videos. Mine is an 81 SC with 182,000 km from Toronto, Canada.
Thanks for watching!
Nice - have an 81 SC with 112k miles in Kitchener. Loved the video as well Nathan!
Thank you this is wonderful. I have been waiting for this!
You’re welcome!
Thanks so much Nathan and PCA!
Bravo, Nathan! Well done.
Great information.
Thanks for watching!
Thank you so much for sharing all of your knowledge
Our pleasure
Thank you for vid , great as usual .
1 questions please .
911 , 911s 911SC , 911 Carrera . I can’t choose , need your advice.
Thanks in advance
Really well done and informative video. Thank you Nathan/PCA!
One thing that I haven't heard many people talk about is the swap to the 3.2 Carrera cases on late model 1983 SC's. I own one and never even realized I had something non-standard until a few years ago when I ordered an 'SC Oil Change Kit' from Pelican, and it came with a sump gasket which my motor does not have. I was super confused and thought Pelican just made a mistake. Turns out Porsche used the soon-to-be-released '84 3.2 cases on some of the last of 198SC's coming through the factory, including mine. Super interesting.
@saturner4214 yes, the 1983 911SC received the updated 3.2 Carrera engine case (still with 3.0 Pistons/cylinders) starting in ~May 1983. It's a nice upgrade for sure!
Good stuff, are transaxles on the list for future model guide videos?
I'm still saving for.i had to get 85 mustang gt on way
Thanks Nathan! I had a great time looking over my '82 SC for all the details as I watched your video. Mine has a Grand Prix White exterior (original paint) / Full leather cork interior with a dark brown (leather-to-sample-99) dash & trim. It also has what I'm calling the 'gold package' with a gold crest on the steering wheel, shift knob, and a gold name plate on the glovebox, with Fuchs rims in gold. Not sure if this was a factory option or added by the dealer. Anyone know?
@petemauro2268 I replied via email, thanks for sending that over, cool car!
Great video. I have been waiting for it ever since you did the mid-year cars and the 3.2. What makes these SC special to me, are indeed the very unusual interior and exterior color combinations. After the SC, it all went black or grey. Question about the electric antennae: when did it deploy in period? When you started the car? When you turned on the radio? Did it stay low if you’re just listening to a cassette tape?
@francoislopin6372 the power antenna goes up as soon as the radio is turned on. I wish it had a seperate switch so for example when I was listening to a source other than radio the aerial wasn't up. It would be easy to wire something like that up, but alas I like my cars original!
I bought my 1981 911 SC new. I ordered it from Porsche+Audi in Triple black metallic. I still own it. I enjoyed watching the video but wish you would have discussed the sunroof.
@rs6er911 curios what you want to know about the sunroof in particular? The vast majority of the US Market 911SC's came here with a sunroof, with each model year the % equipped increased. In today's market non-sunroof cars are preferred, however a buyer should always buy what suits them. So if you like a sunroof, buy one with a sunroof. The system is fairly robust, but it is not uncommon to replace cables/motor with age. Kudos on being an original owner!
@@nathanmerz It seems that the front wind blockers changed somewhat during the run, and I’m curious about when they changed. BTW my tool kit is black, not tan. Did tan interiors come with a tan (brown) vinyl tool kit. Since I bought an ‘81, I’ve always been curious about the early models and the differences. Love the bit about the powered/non-powered antenna. Thanks for a very informative deep dive. One other thing to check on my window sticker which I have: I ordered the front but not rear spoiler. Wonder how that appears in the sticker.
@@rs6er911 The sunroof windblocker was the same from 65-82 and starting late in 1982 it went to a one piece unit (black) vs. the prior 3-piece chrome unit. The later ones are much quieter. Porsche considered the front "valance" to be a spoiler so your sticker will list "front spoiler, black window molding- STD." but that is NOT in reference to the lower rubber unit. If that came on the car without the option for rear spoiler, than it was added by the dealer or subsequent. On my car in the video, it was added by the delivering dealer.
Bought mine after my first big deployment in La Mesa CA. Driven it across country 3 times (Navy does that to you). Have 137K on the clock and it's just about all stock with the exception of a 930 steering wheel (I'm 6'4"), went to period correct BBS wheels when I got tired of chasing 16" tires and replaced the trombone cooler with the -84 right front fender oil cooler. Currently in San Diego for the last 21 years. Every time I think I'd like a new(er) Porsche, I go for a ride. Stops the wants. . .
@@donnewton415 I put a Turbatrol cooler on mine back in the 80’s. I’ve never seen another.
Finally!!!!!
Where on earth can you find all this info on the 911 SC.With my 911 SC being restored now, this was timely.Nobody beats PCA on Porsche,
Good stuff Nathan! I enjoy learning some of the nuances of the cars. I have an '83 SC Cab in Guards Red with white seats and door cards. Is there a source to find out how many cars were made with this combination?
@trj911 Beautiful combo! While rare, it is not unheard of partly due to the fact that the 1st US 911SC sold here was Red on White, some people saw that, liked it and ordered something similar. Porsche does not release build data broken down by color/options. When you see that info in the broad market it is either conjecture (common!) or someone with some wherewithal gathered that information from other sources.
@@nathanmerz Good info, thanks Nathan. I saw Bruce Canapa has (or had) one of the first press cars for sale and it was the same configuration as mine. I'm a big fan of the way your sport seats. Tastefully done and very functional. Thanks again for excellent content!
Oh Yess !!!!
@nathanmerz: I have a 1979 SC delivered new in California. The front and rear screen frames as well as the headlight frames have a bright trim, but the side windows have a black trim. The Porsche certificate lists “Chrome parts black” as an option ticked by the original owner. Could it be that in period, only the side windows would be black? Additional info: the car is highly original otherwise as confirmed by my Porsche Classic Center.
I know it's my opinion... But those stock steering wheels on those period cars are soooo ugly!!! Why????
