General information (source: wikipedia):

The Celica XX (pronounced as “double X”) is the Japanese domestic market name of the first generation model Toyota Celica Supra. It was offered in Japan during the years 1978–1981, and was redesigned in 1981. Toyota obtained engineering assistance from Lotus Cars, and supplied some components for use in the Lotus Excel. The Supra was sold as the Celica XX only in Japan at Japanese dealership sales channels called Toyota Corolla Store, as elsewhere it was sold as the Celica Supra, although they remain popular as grey imports to New Zealand.

The 2000GT was the flagship model of the XX range. Featuring the smaller 2.0-litre six-cylinder DOHC 24-valve 1G-EU, Yamaha took the base 1G-EU and improved it, resulting in the 1G-GEU significantly upping the output of the engine, which also served in the 1985 Toyota Soarer. The smaller-capacity engine meant taxes were less than the bigger 5M-GEU of the 2800GT. 1G-GEU made 160 PS (118 kW) at 6400 rpm.

The 2800GT was the most powerful of the range, featuring the 2.8-litre six-cylinder DOHC 5M-GEU making 175 PS (129 kW) at 5,600 rpm.

The 2000G/S with M-TEU with intercooler made 160 PS (118 kW) at 5400 rpm, as much as the 1G-GEU, but made more torque lower down the rev range, 23.5 m·kgf (230 N·m at 3000 rpm.

The lower-range models, being 2000G/S, were the least powerful, featuring the 1G-EU, which made 125 PS (92 kW) at 5,400 rpm. They also lacked a lot of features found on other models in an effort to lower cost.

In 1981, the Celica XX introduced the world’s first navigation computer.[10]

In late 1981, Toyota completely redesigned the Celica Supra as well as the entire Celica lineup for its 1982 production year. In Japan, they were known as Celica XX, but everywhere else the Celica Supra name was used. Still being based around the Celica platform, there were several key differences, most notably the design of the front end and fully retractable pop-up headlights. Other differences would be the inline-6 still present in the Supra instead of the inline-4 as well as an increase in length and wheelbase to accommodate the larger engine. Vehicles installed with the 5M engine were slightly wider, while other models remained compliant with Japanese dimension regulations. In 1981, Japanese buyers were offered an alternative to the Celica XX fastback bodystyle, called the Toyota Soarer coupe, which was offered at a different Japanese Toyota dealership network called the “Toyota Store“, as the Celica XX was sold at the “Toyota Corolla Store”.

L-type and P-type

In the North American market, the Celica Supra was available in two distinct models. There was the “Performance Type” (P-type) and the “Luxury Type” (L-type). While being mechanically identical, they were differentiated by the available options; tire size, wheel size, and body trim. The P-type had fiberglass fender flares over the wheel wells, while the L-type did not. The P-type was also standard with the more sporty eight-way adjustable seats. The P-type did not get the option of a leather interior until 1983. All editions of the P-type had the same 14×7-inch aluminum alloy wheels and throughout the years the L-type had 14×5.5-inch wheels until 1985 when they were changed to a P-type styled 15×6. The L-type also had the option of a digital dash with trip computer; some Canadian models had this option as well as a few rare instances of American models. The digital dash featured a digital tachometer, digital speedometer, and electronic fuel level and coolant level gauges. The trip computer could calculate and display various things such as fuel economy in miles-per-gallon, estimated time of arrival (ETA), and distance remaining to destination. Excluding the 1982 model, all P-types were available with headlight washers as an option, but the L-types were never given such an option. Although gear ratios changed throughout the years, all P-types came standard with a limited slip differential.


For 1982, in the North American market, the Celica Supra’s engine was the 2,759 cc (2.759 L; 168.4 cu in) 12-valve (two valves per cylinder) DOHC 5M-GE. Power output was 145 hp (108 kW) and 155 lb·ft (210 N·m) of torque. The engine utilized an 8.8:1 compression ratio to achieve the power and featured a vacuum advanced distributor. When the car debuted it clocked a 0–60 time of 9.8 seconds and netted a 17.2-second 1/4-mile at 80 mph (130 km/h)[12]

1982 Supra MkII “L-Type”

The standard transmission for this year was the W58 5-speed manual with the A43DL 4-speed automatic transmission being an option for L-types. Both transmissions featured an overdrive gear and the automatic featured a locking torque converter. The top gear in the 5-speed was its overdrive whereas the automatic transmission featured an overdrive gear that would engage at speeds over 35 mph (56 km/h). The 1982 model’s rear differential featured a 3.72:1 ratio. The Celica Supra’s four-wheel independent suspension was specially tuned and designed by Lotus and featured variable assisted power rack-and-pinion steering and MacPherson struts up front. At the rear, it had semi-trailing arm suspension with coil springs and a stabilizer bar. Braking on the Celica Supra was handled by four-wheel disc brakes.

On the inside, this generation had standard power windows, power door locks, and power mirrors as well as a tilt steering wheel. The power door lock was located in the center console next to the power mirror control. The analog dash of this year only went to 85 mph (140 km/h) in North America. The optional automatic climate control was renovated and was now seen as a standard feature on the A60. Cruise control was standard in this generation. Toyota also included the retractable map light as standard. Some options included the addition of a sunroof, two-tone paint schemes, and a five-speaker AM/FM/MPX tuner with cassette. The optional cassette stereo featured a 105-watt power amplifier and a seven-band graphic equalizer. The standard stereo was a five-channel AM/FM/MPX tuner. Leather was an option on L-types of this year, but P-types were limited to standard striped cloth.

The AM/FM antenna was integrated into the front windshield rather than a typical external mast antenna. There was a key lock on the gas tank door (in lieu of a remote release) and the hatch and rear bumper were black regardless of paint color on the rest of the car. The P-types were available with an optional rear sunshade above the hatch glass. The lights in the rear featured a reverse light in the center and the door handles opened the doors by pulling sideways. The front nose badge and B-pillar only read “Supra” for the first several months of production, but were changed to read “Celica Supra” midway through the model year. L-types had front and rear mudflaps but P-types of this year did not.


For the 1983 models not much was altered, but there was an increase in power output to 150 hp (112 kW) and 159 lb·ft (216 N·m) of torque from the same 5M-GE. The only real change in the engine area was the switch from a vacuum advanced to an electronic advanced distributor, yet that did not increase the power. Toyota switched to a 4.10:1 rear gear ratio for the P-type and a 3.73:1 for the L-type. As for the optional automatic transmission, they replaced the A43DL 4-speed with a newly designed A43DE 4-speed. It featured an electronic controller that would adjust its shift pattern for a balance between performance and economy. It was the first in the industry to provide an electronically controlled transmission (ECT). This allowed the driver to choose either the “power” driving mode or “normal” driving mode at the touch of the button. The power mode provided the quickest acceleration and the normal mode provided the best all-around performance.

On the inside of the car there were virtually no changes, but changes to the exterior included a switch to a power mast antenna, mudflaps on all models, and the addition of headlight washers on P-types. All B-pillar and nose badges for cars sold in North America read “Celica Supra” and only P-types were available in two-tone color schemes.


1984 Supra A60 P-type

In 1984, Toyota changed quite a bit on the Supra. Power output was increased on the 5-speed models with a bump up to 160 hp (119 kW) and 163 lb·ft (221 N·m) of torque. The increase was achieved by a mixture of a redesigned intake manifold with “D”-shaped intake runners and an increase in compression ratio to: 9.2:1.[2] Another notable change in the 5-speeds was the switch to a 4.30:1 gear ratio in the rear differential. All automatic Supras retained the previous years power numbers, but the rear gear ratio was changed to a 4.10:1.

The most notable exterior change was the switch to wraparound front turn signals. Also on the outside the tail-lights were redesigned and the hatch received a billboard “Supra” sticker instead of the smaller sticker, which was previously positioned on the right. The rear hatch and bumper was changed and received the same color as the rest of the car (instead of the black of previous years). The door handles were also switched around, opening by pulling up instead of sideways. This year Toyota also decided to offer two-tone paint schemes on both the P-type and L-type.

Some interior controls such as the steering wheel, cruise control, and door lock switch were redesigned. Toyota included a 130 mph (210 km/h) speedometer instead of the traditional 85 mph (140 km/h) one and the automatic climate control display was also changed. The previous year’s cassette and equalizer stereo option was now made a standard feature.


The Supra was altered again in 1985. On the engine side, power output was increased to 161 hp (120 kW) and 169 lb·ft (229 N·m) of torque. All Supras this year had the same amount of power (both automatics and 5-speeds). The engine received a redesigned throttle position sensor (TPS) as well as a new EGR system and knock sensor. With the slight increase in power the Supra was able to propel itself from 0–60 mph in 8.4 seconds and netted a 16.1 second quarter-mile at 85 mph (137 km/h).[13]

Other changes would be a redesigned, more integrated sunshade and spoiler on the rear hatch. The rear spoiler was changed from a one-piece to a two-piece. The L-types of this year were not available with a leather interior, but P-types were. Toyota added a standard factory theft deterrent system and the outside mirrors were equipped with a defogger that activated with the rear defroster. All Supras this year received automatic-off lights that also encompassed an automatic illuminated entry and fade-out system.

While 1985 was to be the last year of the second generation model, delays in production of the third generation model led to a surplus of second generation Supras. During the first half of 1986 the 1985 P-type was still offered for sale, with only minor cosmetic changes as well as the addition of a now mandatory rear-mounted third brake light on the hatch. These were all labelled officially as 1986 models. P-types were the only model available in 1986.
