The Toyota MR2 as it’s known in the United States was actually part of a redesign in 1990 that led to the chassis we know as the W20. Powered by the turbocharged 3S-GTE that was a bit ahead of it’s time, the rear wheel drive sportscar had a brief glorious run in the US from 1991-1995.
In fact the SW20 MR2 is one of the pioneers of the small displacement turbocharged rear wheel drive import coupes, and sported traits that many of todays manufacturer’s strive to achieve today.
Four trims were available in the Japanese Domestic Market (JDM) however, there’s just the non turbo and turbo versions that made their way stateside. Putting down 200hp in stock form, many engine swappers import the 3S-GTE in for a variety of rear wheel drive donor chassis.
