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 SR20DET 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.



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.
