1970 – 1971 Porsche 911 T 2.2 (LWB) – Ultimate Guide

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.

After four years in production, Porsche released a 911 with a larger 2.2-litre engine. The original two-litre unit had served the firm well, but the move to a bigger displacement for the 1970 model year meant more power, improved torque and, most importantly, better performance. Competition had heated up, with Ferrari and Lamborghini amping up their efforts, so when the C-series 911 entered production in August 1969 it had a lot riding on it.

2.2 C-Series (1970)

The familiar all-alloy air-cooled Flat 6 with its single overhead camshafts and dry-sump lubrication was bored from 80mm to 84mm. Stroke stayed at 66mm for a displacement of 2195cc (a gain of 204cc over the outgoing unit). Porsche’s engineers fitted bigger valves, new head gaskets and more cooling fins on the cylinder barrels which had modified ends to clear the longer bolts required by stronger con rods. The 911 T had the Type 911/03 engine designation, with 8.6:1 compression and two Zenith 40 TIN carburetors. Power came in at 125 bhp @ 5800 rpm and torque was 131 ft lbs @ 4200 rpm.

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. The steel bodyshell was now coated with a Tectyl oil-based anti-corrosion fluid, a huge update when it came to rust-prevention. Suspension was fully independent with torsion bars and telescopic shocks fitted all round. The front end used a compact MacPherson strut arrangement with a single lower wishbone while at the rear, semi-trailing arms were installed. For these 1970 model year C-series derivatives, the front suspension mounting points were moved 14mm forward to reduce front wheel castor and lighten the steering at low speeds. Front torsion bar adjustment was made easier on the 911 T and 911 S.

Ventilated disc brakes were now fitted across the board but, to keep costs down, iron rather than alloy calipers were used on the 911 T. Also standard were 6 x 15-inch Fuchs forged alloy wheels although 911 Ts destined for certain markets did still come with steel rims.

Cosmetically, no major changes were made. Upgrades included new door handles with an opening trigger behind the catch and improved Bosch H1 headlights. A 2.2 decal was applied to the base of the rear screen. To save weight, aluminium was used instead of steel for the engine cover and the central part of the front bumper on 911 E and 911 S variants. The E and S also had anodized gold badging at the back compared to bare aluminium for the 911 T.

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)

The subsequent 1971 model year D-series 911 came with another series of updates. In the fight against corrosion, bodyshells were now galvanized with a zinc coating applied to exposed underbody areas. Crankcase squirters were introduced to improve piston cooling. There was also a new type of sealed chain tensioner while minor detail alterations were made to the fuel-injection system.

Inside, a new twist and pull type knob was fitted to the glovebox and a ‘1969 & 1970 World Championship of Makes’ decal was applied to the driver’s side rear window. US-spec. derivatives now came with a fuel evaporative control system to prevent the release of vapor into the atmosphere. A heated front windscreen was added to the options list.

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.
