911′s are one of the world’s most modifiable cars due to commonality of components during its production and this is one reason why they are so popular. The inherent durability made these the most successful production-based race cars of all time.

One can upgrade the torsion bars, shocks, bushings, anti-roll bars, and brakes for street use, Driver’s Education events, or competition without much effort and every air-cooled engine will interchange, provided the right components are installed.

Below is a brief overview of the first few generations of these superb air-cooled cars and their features as well as differences. Contact us for more details and consultation about improving every aspect of these cars.

Short wheelbase 1965 to 1968 2.0 litre 911, 911S and 911L

Porsche made these cars in various states of tune ranging from the 911 & 911L’s 130HP to the 911S 160HP, and even more with the factory Sport kit I and II. Two different intake systems were used, Solex 3bbl carburetors and later on, Weber 40 IDS 3C’s  for improved drivability and ease of tuning. Changes to carburetors, camshafts, valve sizes, and heat exchangers helped account for the power rating differences.

These models respond very well to suspension upgrades as well as engine modifications. With the use of modern tires and some suspension tweaks, the car’s reputation as being twitchy becomes much more benign and forgiving. Brakes can also be upgraded for improved performance, something especially important when adding more power to the car.

 ’69-’73 911T, 911E  and 911S

These LWB models were also offered in several states of tune starting with the carbureted 911T, progressing to the mechanically fuel-injected 911E, and finally with the most powerful 911S. Differences between cars were mainly around the engine, suspension, and exterior trim. Any model could be delivered with the “S” suspension, brakes and exterior trim. Engine differences between T, E, and S models were focused on intake systems, cylinder heads, camshafts, pistons, crankshafts, and connecting rods.

All of these cars can be upgraded with varying suspension modifications, brake upgrades, close-ratio transmission gears, and engine modifications. Depending on how the car is used, RS can recommend and provide several performance packages to improve the handling and acceleration to one’s objectives.
