Drivetrain and Cooling Considerations The transmission choice often falls to the robust R154 manual or the Aisin-Warner automatic from the donor Supra. Furthermore, the 240SX benefits from a modern, factory-equipped rack-and-pinion steering system, eliminating the need for the complex and often expensive power steering conversions required for older Skylines.
Cooling is another critical factor that cannot be overlooked; the concentrated heat from the inline-six requires an expanded radiator core, often necessitating an external transmission cooler and an upgraded electric fan to ensure optimal temperatures are maintained during spirited driving or heavy traffic. This combination transforms a nimble sports car into a formidable performer capable of handling substantial power without compromising its sharp handling characteristics.
