actually they did have the 4g63t just not here
and as far as dsm, it was still a joint venture so...
here ya go
The Starion used a traditional front-mounted engine with rear-wheel drive layout, which most sports cars use. Many came with a limited slip differential and anti-lock brakes (single channel, rear wheels only) as standard features. The entire chassis was derived from the previous high performance variant of the Mitsubishi Sapporo or Galant Lambda sports coupe, with a MacPherson strut front suspension and semi-trailing arm independent rear suspension.

Engine capacity was 2.0 L with the now well-known 4G63 2.0 L engine, subsequently featured in the Mitsubishi Lancer Evolution series of automobiles. However, American customers received the larger G54B 2.6 L engine but without any additional horsepower. Neither was DOHC. After 1987, European Starion models were also fitted with the 2.6 L engine, as was the GSR-VR for Japan. Both engines featured computer controlled fuel injection and turbocharging.

Horsepower varied between 150 and 197 bhp 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 also built for the Japanese market, however production ceased in 1983 due to low sales figures. The Starion GX had no electric windows, no air conditioning, no independent rear suspension, no fuel injection and did not have power-assisted steering.

Seating was a 2+3 arrangement, although the rear seats are not too suitable for large adults. The front seats were adjustable for lumbar, angle, knee support, position and featured variable-angle side-braces.

One of the more unusual features was that the seatbelts were located in the doors for the driver and front passenger, and some American and European models featured electrically operated seatbelts.

A five-speed manual transmission was standard in most models, however, an automatic transmission was sold as an option in some markets.

The drag coefficient was around 0.32; quite efficient for the era, and although quite angular, the aerodynamics in general were exceptional at the time.
