Default deciding between an sc or 3.2

Recently sold my 964 and purchased a 997. Love the 997, but wanna get back into the aircooled world. Never liked the looks of the 964 and want the torsion bar suspension feel. Cannot afford the later 3.2s and hear that the sc's are the most maintenance free aircooled porsches ever made. Please advise, should I be looking for an sc or early 3.2? My budget is upper 30s. And it must be a coupe.

If you can score a good shape 3.2 in your i price range get it. The 3.2 is a great engine and has gobs of power over the sc as it's motronic can be chipped.
The 3.0 undoubtedly us a solid power plant if you can handle the CIs.

More interested in mechanical reliability. My old 964 ate me alive in maintenance. Don't care about power, just like the raw feel of cornering and long armed shifting. I feel like I can get a decent sc in the low 30s, whereas a 3.2 is more upper 30s, low 40s...no thanks. For that money, I will but a 993 tip.

CIS = "Continuous Injection System"

964 is not maintenance intensive. your example may have had deferred maintenance.

SC and 3.2 are both extremely reliable. but yes 3.2 is a bit cheaper.

The SC didn't get really good until '82. Early SCs had air pumps, and were de-tuned, at least in the USA. I'd say a 915 transaxle 3.2 is what you're looking for.

Other people say the early SCs are better because they have "bigger ports". The books I have all say all model year SCs are largely the same and no single year is more desirable.

OP, if I were you I'd much rather buy a good SC than a so-so 3.2.

All points above are true except a 3.2 will not be cheaper than an SC
All SC are reliable. Regardless of year. And in the big picture all 3.2 are also
As mentioned CIS is the fuel management and its mechanical On the 3.2 it has electronic injectors and management .
From a reliability standpoint you can have good and bad in both

In an SC the cis can be finicky. But mine has been great. The only thing to watch out for is that head studs have been replaced. As that is a major expense.
In a Carrera ( 3.2) you have more sensors that can fail that go along with early electronic systems so on a pure numbers standpoint the carrera is less reliable. They have dme relays, reference sensors, head temp sensors , etc that go bad time to time. But that would not turn me off.
The only real issue on Carreras are bad valve guides in some and that is a major expense.
You can have good and bad examples in both classes so I think it's a wash.

Find the one you like. Have it checked with a ppi and pull the trigger.

AGREED! I drive a 78'SC and I made the decision to go SC after driving both 3.0's and 3.2's ... The 3.2's that I drove were mostly stock and felt a little sluggish and or heavy to me... the early SC's, mine especially, feel more nimble. It might be because mine is very much a stripper car..no sunroof, no power windows , no ac..not even a passenger side mirror. I think the 3.2's have more top end power and the early SC's are quicker off the line. Maybe I just really like my car and in all honesty the rule of getting the best example of either that you can afford stands.

Catherine - the SC's and their CIS fuel injection (FI) are more susceptible to ethanol blend problems than the Motronic on the 3.2L motors

CIS is not a suitable FI system for a sports car either; the electronic fuel injection on the 3.2L is far superior and a more evolved version is still used today

also, you can gain a few hp by shipping the 3.2L

it's true, a 3.2L car will generally cost more for equal condition over a 3.0L car - BUT it is worth it

the only drawback to the 3.2L cars is additional wt. (caused by more luxo creature comforts) - you can easily remove it tho

you will want to go slow on your shifts with the 915 transmission on either car (you seemed to rule out the G-50 cars above)

Take a look at the compression numbers and bhp.

Maybe your books will have that info.

Lots of opinions and suggestions here and all worth noting. All years of Porsches have their "issues", some more expensive to resolve that others. Maintenance history is the key. Pick the car that fits your budget, get a PPI, buy, drive, and enjoy.

sounds like his books are wrong - the bigger ports are useful when changing to carbs, etc.

I would recommend buying the best condition 911 you could find. Both the 3.0 and 3.2 engines are reliable if maintained properly. Upper 30s should get you a solid 3.2 driver and real nice SC.
