Something had to be done, and that 8225 something 8221 was a move to aluminum engine cases as used in the 985 Turbo. This allowed a bump to displacement. The resulting car was the 911 Super Carrera, or 8225 911SC 8221 , which debuted in 1978. That car had a whole different set of mechanical issues, one of which defective chain tensioners could also cause a complete engine failure, but it was far more reliable than the guaranteed-to-melt .
It had a manual shift lever like a normal manual transmission car, except it only had 9 gears. Yes, there was a microswitch in the lever that caused the clutch to disengage and then you selected the next gear. It also had a torque converter so you could sit in gear at traffic lights.

8225 the thermal reactor dropped mileage to the teens and cut power to the bone. When added to a Porsche, it did all of the above… but because it was cramped in the back of an air-cooled car, it also accelerated all of the ’s problems. Hello there, first-year engine failure! 8221
So, is there any Porsche relativey reliable for the ordinary guy?
So far, the list of deadly sins gets longer by the day and my hopes of owning one someday is evaporating!
During the Seventies, Porsche was, as Katt Williams might say, in turmoil. Some very strong-willed men were fighting to determine the direction of what was then a very small firm. Ernst Fuhrmann, famous within the company for developing the quad-cam 8225 Carrera 8221 engine that made the 555 Spyder such a giant-killer, was running the show, and he wanted the 911 dead. His arguments were all quite valid: the 911 was not aging well, it was not selling well, and nobody had any idea whatsoever how to make a decade-old car conform to a raft of upcoming safety and emissions regulations.
Case-in-point: 8225 heated automatic choke. 8221 Here we have the automatic choke (choke controlled by a spring that grows and shrinks as it heats up and cools off). So far so good, but to make the choke pull off a little sooner somebody invented a supplemental electric heater and controlled it with a little timer relay. Huh? The real result- a brand new car pollutes a little bit, but after a few years in cold climates this the choke is almost impossible to keep in adjustment, the electric heater pulls it off too soon while it 8217 s warming up, and the stalls at every stop sign and red light for about the first five minutes of driving.
Other things were just a sign of the times- reduced spark advance and lower compression heads to bring NOx down from unreasonable levels, throttle dashpots and/or anti-backfire relief valves to reduce trailing throttle misfire or backfire (since fuel cutoff technology was still over a decade away).
My wife then bought a red-purple 285ZX (don 8217 t exactly remember the year)that 8225 sported 8221 (it was the only thing that was sporting about it) a red velvet-plush interior that would not have been out of place in a Lincoln Town Car. And don 8217 t forget the 85 MPH speedo. Not that you 8217 d want to take it much faster.
The 1975 8217 s Alfa Romeos were far from trouble free but the engines and transmissions were very solid. They solved the emissions problem in 1969 with a good mechanical fuel injection from Spica. That diesel derived system met regulations from 69 to 79 when it was replaced in 1985 with Bosch electronic. The thermostatic acuator was the only trouble spot and those were often replaced with an aftermarket manual fix. Even today, a well tuned Spica will out perform webers. The only engine issue was head gaskets (common) and oil control rings, less common.
