【Car Accessories】Master the oneness of man and horse! "Fine-tuning Rebuilt Engine" for ND Roadster and more

Developed with the concept of "a street best specification that allows you to experience the refinement of 'man and horse as one' without compromising ease of use or durability," this rebuilt engine for the ND Roadster has finally been crafted by skilled artisans, achieving an ideal feel that mass production cannot offer. This is a custom part that you will want, even if it takes time.

Precision and weight/rotation balance beyond mass production!

Autoexe's "Fine-Tuning Rebuilt Engine" for the ND Roadster makes its debut with great anticipation. Clearances, weight, and rotation balance have been meticulously refined beyond mass production standards, with modifications made to the port, combustion chamber, and valve area shapes based on unique know-how.

In addition, three items that optimize cooling efficiency for sports driving are also lined up. If installed during engine replacement, it can also save labor hours.

The "Sports Radiator" uses an all-aluminum 2-layer core (core thickness 36mm, pitch 3.5mm). It achieves an 18% improvement in heat dissipation compared to the mass-produced 14mm core, and a 3% improvement compared to the NR-A large capacity (25mm). Even under high load, it provides ample cooling performance, enhancing stability during continuous driving.

The "Sports Radiator Cap" lowers the boiling point of the coolant with a venting pressure of 127kPa (13kg/cm2), maximizing radiator performance. Heat-resistant silicone rubber is used in the sealing part, maintaining sealing performance for a long time even under high temperatures and preventing pressure drop.

The "Sports Thermostat" is set to a venting temperature of 75℃ (genuine 88℃), helping to suppress the rise in water temperature during sports driving by circulating at a lower temperature to the radiator. A high-response type equivalent to the genuine part is used in the sensing part, allowing for quick opening and closing by concentrating the coolant in the sensing area. Stable water temperature control is possible.
