1996 models received the biggest changes for the 993 – most notably, a new Vario-Ram intake system. As the name suggests, this system varies the length of the intake runners to boost mid-range torque. In addition, the system uses twin-resonance tuning (“vibrating tube intake system”, as Porsche calls it) to increase top-end power. Peak horsepower and torque is increased over the 1995 models
Porsche has spent years perfecting these complex intake systems on their race cars, and by transferring the technology onto their 911, they have successfully produced an engine with a volumetric efficiency greater than 1 (meaning that the volume of air sucked in is greater than the volume of the cylinders. This is how a naturally-aspirated engine is “boosted” without forced induction)
However, Vario-Ram engines developed a bad habit of clogging the Secondary Air Injection (SAI) passages, causing the “Check Engine” light to illuminate and preventing the car from passing smog. Cleaning out the SAI ports can usually fix the CEL issue, but many owners are forced to get a valve job or top-end rebuild in order to cure the issue. This is arguably the biggest headache with the 993
The base 911 Carrera uses the same engine as the “S” model, and makes the same exact power. In fact, the base coupe is slightly quicker (in acceleration) than the heavier “S” model. It wasn’t until the 997 generation when the “S” models made more power than the base 911
This is the first generation of 911 to use a 6spd manual. It was essentially the same G50 5 speed used in the previous generation, but with an extra gear added
This was also the first 911 to use hydraulic lifters, eliminating the need for routine valve lash adjustment
Key Model Year Changes:
First year of the Vario-Ram engine (M64/21)
Power increases by 15hp and 8 lb ft of torque
First year of the “Immobilizer” keyless remote locking system
First year of OBD-2
The following year (1997) was the first year of the illuminated ignition switch, as well as the final year of the base Carrera coupe (only the Targa, “S” coupe, cabriolet, and Turbo are available the following year (1998)
1997 models received minimal changes, and are nearly identical to 1998 models (final year of the 993)
