Overview

TOMEI USA is proud to announce the re-release of the KA24 Turbo Exhaust Manifold!
We have enhanced materials and manufacturing while preserving the original design, achieving greater durability, performance, and a sleek appearance.
Since its launch in 2015, this manifold has earned high praise from 240SX S13/S14 owners.
Designed for seamless compatibility with SR20 components, it enables efficient turbocharging for KA24 engines, delivering a significant performance boost.
However, due to mold deterioration, production was discontinued in 2022.
Now, after three years of development, it returns with major refinements.
We upgraded from cast iron to high-quality stainless steel, using advanced lost-wax casting for superior durability, heat resistance, and easier installation.
Optimized for the KA24’s long-stroke design, this manifold delivers smooth, torque-rich power, excelling in both daily driving and high-performance applications.
We appreciate your patience and support. This is our best version yet, and we hope all KA24 enthusiasts will enjoy its benefits.
Unlock the full potential of Nissan’s KA24 engine with this advanced turbocharging solution!

Appearance Improvement

  • Smooth and seamless finish, enhancing the factory-like aesthetic.
  • Beautiful silver-toned exterior, providing a premium and long-lasting visual appeal.

Characteristics of KA24

  • The KA24 engine features a long 96mm stroke, making it less suitable for high RPMs despite being a naturally aspirated (NA) engine.
  • While the KA24 is not originally equipped with a turbocharger, it is, in fact, highly compatible with forced induction.
  • Turbocharging enhances the inherent benefits of its long-stroke design, significantly increasing low- to mid-range torque.
  • As a result, it enables a more enjoyable and dynamic driving experience, whether in city traffic or on the racetrack, delivering both power and comfort across various driving conditions.

Compatibility with a Wide Range of SR20 Parts

  • The exhaust manifold is designed to position the turbo in the same location as on SR20DET-equipped vehicles, such as the Nissan Silvia and 180SX.
  • It offers broad compatibility with OEM SR20 parts, including:
  • Turbochargers
  • Turbo Outlet pipes (Elbow pipe)
  • Front pipes
  • This design allows KA24 owners to seamlessly experience turbocharged performance, as if a factory KA24DET variant existed.
  • Prioritizing ease of installation and a factory-like appearance, the manifold is engineered to fully unlock the potential of the KA24 engine.

Comparison with Other TOMEI Exhaust Manifolds

Our exhaust manifold designs for engines such as the RB26 and 4G63 utilize SUS304 stainless steel welding construction.
These designs emphasize performance enhancement, weight reduction, and a higher-pitched engine sound.
In contrast, the KA24 Exhaust Manifold is engineered with a different philosophy:

  • Specifically designed for turbocharging a naturally aspirated (NA) engine.
  • Prioritizes a factory-like appearance and exceptional durability.
  • The lost-wax casting method enables a seamless turbo conversion with minimal modifications.
  • Delivers outstanding performance, even in urban driving conditions.

4G63

Proven Technology from the SR20DET Manifold

  • Incorporates the same unequal-length design used in our SR20DET manifold, ensuring exceptional turbo spool response.
  • As a result, it delivers a smooth and highly responsive turbocharged driving experience, tailored for KA24 enthusiasts.
  • With its combination of enhanced durability, seamless installation, and compatibility with existing SR20 parts, the KA24 Exhaust Manifold is a premier choice for those seeking to upgrade their KA24 engine for a more refined and powerful driving experience.
