CA18 OEM Position Manifold

Our CA18 OEM position manifold for the Silvia S13 (180SX / 200SX) is hand-made in-house from high-strength 1.4541 V4A . The runners have a wall thickness of 2.6 mm.

The CA18 OEM Position manifold offers all the advantages of shock charging technology by simply replacing the standard manifold , and thus ensures noticeable increased performance , especially at the limit.

The position of the turbo and the original flange pattern remain the same, meaning that hardly any changes need to be made to the periphery. Charge air piping, downpipe and the supply of media (oil, water) to the turbo can be retained.

The pulse charging principle achieves a significant increase in turbine efficiency compared to conventional turbocharging, as the turbo is not driven by the exhaust pressure, but by individual exhaust pulses that are fed to the charger inlet. The result is improved spool-up , significantly higher charger efficiency , earlier response , maximum peak power and a wider torque band . In addition, exhaust back pressure is reduced, which leads to a lower exhaust temperature , higher scavenging effect and better fresh gas filling .

Our collectors are also handmade. We attach great importance to the angle of attack being as sharp as possible in order to ensure optimal flow to the exhaust housing and selective activation by the exhaust gas pulses.

In addition, we always try to achieve the best possible pipe length compensation in terms of installation space and charger position in order to guarantee the maximum efficiency of the manifold.

Our flanges are made of a steel alloy that has reduced thermal expansion and is also less susceptible to distortion.
