Mitsubishi Starion


The Mitsubishi Starion was a two-door, turbocharged four-cylinder rear-wheel drive four-seat hatchback sports car that was manufactured by Mitsubishi from 1982 to 1989. Rebadged variants were marketed in North America as the Conquest under the Chrysler, Dodge, and Plymouth brands.
The Starion is one of the first modern Japanese turbocharged performance automobiles with electronic fuel injection.

Overview

Mitsubishi began marketing the Starion in 1982, during a period in which a number of Japanese grand tourer sports cars were available, including the Nissan Z cars, Mazda RX-7, Toyota Supra and to a lesser extent, the Honda Prelude, Isuzu Piazza and Subaru XT.
The Starion was marketed in the US under Mitsubishi as the Starion and badge engineered variants of were marketed as the Dodge, Plymouth and Chrysler Conquest. In the UK it was sold as the Colt Starion.
Manufactured in two body configurations; a narrowbody and widebody, the narrower style complied with Japanese exterior dimension regulations taxing larger vehicles and engine displacement exceeding 2,000cc. Only the narrowbody was offered through the 1985.5 model year.
The introduction of the widebody also split the car into two ranges: a non-intercooled lower-horsepower car using the narrow body style and a high-performance intercooled widebody. In most markets, widebody cars were given the label of Starion ESI-r or Conquest TSi. Markets that never received the widebody had the ESI-r label, these cars had similar performance as the widebodies. Widebody cars were offered in 1986-1989 model years in the US.

Name

Mitsubishi says "Starion" is a contraction of "Star of Arion" — and refers to both a star and the mythical horse, Arion.
Several sources attribute the name to struggles by Japanese engineers to pronounce the word stallion. Automotive journalist Paul Niedermeyer noted that an early Japanese television commercial for the Starion closed with a logo of a stallion's head with the word "Starion" below it. The translation of the voiceover says the name refers to a star and the mythical horse, Arion. The Mitsubishi Colt and Mitsubishi Eclipse featured equine names, with the Eclipse named after the champion racehorse.
Marketing material from 1982 somewhat confirms the official explanation.
On an episode of BBC`s Top Gear, Jeremy Clarkson says the name was supposed to be stallion however it was misunderstood as "Starion" in a phone call with the marketing team and the name stuck since then.

Design

The Starion uses a traditional front-mounted engine with rear-wheel drive layout. Many came with a limited slip differential and anti-lock brakes as standard features. The entire chassis was derived from the previous high-performance variant of the Mitsubishi Sapporo or Mitsubishi Galant Lambda sports coupe, with a MacPherson strut suspension and sway bars that were fitted to the front and rear. Rack and pinion steering was not offered, instead gearbox steering was standard on all models.
Engine capacity differed between markets. American customers received the larger SOHC Astron G54B 2.6 L engine. Most markets received the SOHC 2.0 L Sirius G63B engine, subsequently featured in DOHC form in later Mitsubishi sport compacts such as the Mitsubishi Lancer Evolution. Both the 2.0 L and the 2.6 L produced roughly the same horsepower, the larger 2.6 L did have a slight torque advantage and the 2.0L had a higher redline. Reporters of the time considered the 2.0l to be peaky and exciting, while the American market 2.6l had plenty of torque, but was less rewarding. Both engines featured computer-controlled fuel injection and turbocharging. After 1987, European Starion models were also fitted with the 2.6 L engine, as was the GSR-VR for Japan. The move to the 2.6 L in all markets was spurred by emissions restrictions around the world tightening to meet the American standards for lead in fuels. Reviews during the change were negative as many felt the car was slower, for most of these markets this was the case as the engine change also coincided with a move to the heavier body style.
From 1984 until 1987 in Japan a 12-valve SOHC intercooled version of the 2.0 L G63B was made available in the top-spec GSR-V trim grade Starions. This setup was known as the Dual Action Super Head due to its ability to activate the third intake valve above a certain RPM, thereby increasing top end response, flow and overall engine performance. Redline was increased to 7000 rpm on these models.
Horsepower varied between depending mostly upon the turbocharger that was fitted, the presence of an intercooler, and whether the 8-valve or 12-valve head was used.
A naturally aspirated version known as the GX was offered in the Japanese market, with production ending in 1983. The Starion GX was offered without power windows, air conditioning, independent rear suspension, fuel injection or power-assisted steering.
Seating was a 2+2 with rear seats unsuitable for large adults. The front seats were adjustable for lumbar, angle, knee support, position and featured variable-angle side-braces.
Front seat belts were located in the doors for the driver and front passenger. 1987 and later American models featured electrically operated seat belts. Newer models also featured power windows that remained powered up to 30 seconds after the engine was turned off.
A five-speed manual transmission was standard in most models, however, an automatic transmission was sold as an option in some markets.
Later upgrades to the model included an intercooler, five-lug wheels replacing the four-bolt wheels it had shared with the rear wheel drive Mitsubishi Galant Lambda, rear power train changes from four- to six-bolt axles, various fuel management upgrades and upgrades to the transmission.
Towards the end of the models US run a widebody could be bought with a "Sports Handling Package" or SHP. This included adjustable front and rear struts and 1 inch wider wheels. The SHP was only offered during the '88 and '89 model years. The package can be retro fitted to earlier pre-widebody cars.
In 1988, a Special Edition Conquest TSI-SE was marketed to commemorate various IMSA and SCCA championship wins. It consisted of these vehicles from the first 500 of the assembly line in Japan. They featured all US dealer options, including SHP packages, a revised PCI-ECM with "over-boost", HD BorgWarner JM600 four-speed automatic transmission with push button overdrive and fourth gear lockout and an exclusive "Group-B" yellow exterior color scheme. A one-year only limited production run.
The drag coefficient was around 0.32, superior to the Mazda RX-7 and the Nissan 300ZX upon its release.
Notable upgrades included multi-port injection consisting of standalone engine management to control individual fuel injectors, one per cylinder versus the stock PCI-ECM two injector system. Two injector systems, primary and secondary non-sequential firing and sequential firing.

Motorsports

The Starion was a prominent competitor in motorsports up to International level during the 1980s and performed well on the circuit in Group A and Group N races of the era. Andy McLennan driving a Simmons Drums sponsored Starion was very successful, picking up many race wins and a Monroe championship, this against the semi works car of Colin Blower. In the Netherlands, John Hugenholtz won the over 2L class in the Dutch Championship, with the Colin Blower-prepared Mitsubishi Dealers car. In the United States, the Starion became best known for successes in endurance racing. Starions from Dave Wolin's Team Mitsubishi, with turbocharged 2.6 L G54B engines built by noted Lotus engine guru Dave Vegher, captured the prestigious "Longest Day of Nelson Ledges" 24-hour endurance race four years running from 1984 through 1987. Team Mitsubishi Starions also won the Sports Car Club of America U.S. Endurance Championships three of those four years, competing against the fully factory-backed efforts from Chrysler, Audi, Nissan and Mazda. Although not commonly seen in modern motorsports, a number are still raced on both circuit and in special stage rally events, usually by privateers.

Starion 4WD

The Starion was not very successful off-road, but found victory in Group A World Rally Championships and Asia Pacific Rally Championships during 1987 and 1988. An all wheel drive version of the Starion was also produced for Group B specifications, but after an encouraging start as a prototype, it was not homologated before the FIA banned Group B cars for safety reasons. The Starion was converted to all wheel drive by adding a strengthened transfer case from a Pajero behind the transmission. This configuration allowed the engine to be situated well back in the chassis, for improved front/rear weight distribution compared to the Audi Quattro, whose configuration required the engine to be far forward in the car. Although the wheelbase did not change, the use of regular headlights rather than the production model's pop-up headlights allowed the nose to be six inches shorter, as well as saving several pounds in weight. Further weight was saved by the use of carbon fiber for the driveshafts, sumpguard, and lower arms of the suspension, and fiberglass for the hood, tailgate, door skins, fenders, bumpers and spoilers, resulting in a final weight of less than, lighter than the Audi Quattro. The car was developed with a turbocharged and intercooled version of Mitsubishi's 2.0 L fuel injected engine, but the final goal was to use a turbocharged and intercooled version of the Sirius Dash engine that Mitsubishi announced at the 1983 Tokyo Motor Show, which switched electronically at 2500 rpm from one inlet valve per cylinder to two. The car was campaigned for Mitsubishi by Team Ralliart in Essex, Great Britain, under rally veteran Andrew Cowan and engineer , who had developed the Audi Quattro for Audi Sport UK.
