The Porsche 911T continued as the entry level 911 for the 1970 and 1971 model years, sitting below the 2.2L 911 E and the 2.2 L 911 S. The 911 T featured all the upgrades that came with C-Series production updates including longer wheelbase and Fuchs alloy wheels. During its production years it was available as both a Coupe or Targa bodystyle.
It didn’t take Porsche long to want to give the 911 more power in order to compete more effectively in racing and keep customers happy. So in 1970, in came the larger and more potent 2.2-litre engine. More power, more torque and a decent improvement in performance were the result.
2.2 C-Series (1970)
The Flat 6 engine got to its 2.2 liter displacement thanks to an increase in bore from 80mm to 84mm, with Stroke unchanged at 66mm. Total displacement was 2195cc. Porsche also added other enhancements to the engine including bigger valves, new head gaskets and more cooling fins on the cylinder barrels. The engine type was also unique to the 911 T (Type 911/03). Power came in at 125 bhp @ 5800 rpm and torque was 131 ft lbs @ 4200 rpm thanks to a 8.6:1 compression ratio and two Zenith 40 TIN carburetors.
The 911 E and 911 S got more power than the base T, instead of making do with a 125 bhp engine, they both got 155 bhp and 180 bhp respectively.Whereas the 911 E and 911 S came with a five-speed gearbox, the 911 T had only four-speeds. The performance of the base 911 T wasn’t that great frankly, with 0 – 60 mph taking 9.5 seconds, while the quarter mile took 16.5 seconds. Top speed was 127 mph.
The 911 T was the only 2.2-litre derivative that had a specific US-market version as the 911 E and 911 S could be exported to the States without needing any compliance modifications. Output was unaffected but the emissions-equipped 911 T engine was given a new type number (911/07).
The T also got the rest of the updates that came with the C-Series update including a structure coated an anti-corrosion compound and full suspension was fully independent suspension. Front suspension set up was a MacPherson strut with a single lower wishbone, while the back got a semi-trailing arms set up. For those trying not to die, the addition of ventilated disc brakes was a welcome upgrade while the standard forged alloy 6 x 15-inch Fuchs completed he look.
C-series production started in August 1969 and continued until July 1970. A total of 6,544 911 T Coupes were produced and 2,545 911 T Targas were made.
2.2 D-Series (1971)
Another year, another year of small improvements. The 1971 D-series cars were now galvanized with a zinc coating applied on the bodyshell. Porsche engineers added squirters to improve piston cooling while improvements were made to the fuel-injection system.
D-series production ended in August 1971 to make way for the new 2.4-litre E-series variant. A total of 2,517 911 T Coupes were produced and 3,476 911 T Targas were made. For model year 1972, the 2.2 liter 911T was replaced by the 2.4L 911T.
