Here's why:
* All 1987 Supra models came standard with fuel injection. This was a common feature for cars of that era, especially in Japan.
* Turbocharged models existed. The 1987 Supra offered both naturally aspirated (non-turbo) and turbocharged engines.
Therefore, a 1987 Supra could be fuel injected, but the turbocharged engine was also available. To know for sure if a specific 1987 Supra is turbocharged or not, you would need to check its specific model details.
