Product Description

This intake collector is a standard item in the NISMO Z-tune GT-R34 Ver.2002. It is completely bolt-on installation, and no modifications on are necessary on the idling control, fuel piping, clutch piping & vacuum piping. (The only minor adjustments needed are on the throttle linkage & throttle sensor). Improved medium speed torque is achieved by improving airflow onto each cylinder, and this is done by refining the diameter & length of the inlet pipe & cross section of the intake collector.

Normal Collector Based on factory item with respect to form factor, air is not evenly distributed to all 6 cylinders. As a result, the NISMO air collector tried to distribute air flow evenly & equally by redefining the intake form factor.

There is a difference in turbine inlet exhaust gas temperature between the front & the rear. The overall temperature difference has been reduced drastically due to an improved & efficient intake quantity between the cylinders on both sides. (The exhaust gas temperatures at the front-rear turbine was reduced at an average of 18% at 2400 RPM to 7000 RPM) The fuel supply density is high in order to protect the turbocharger from high exhaust gas temperatures. With the NISMO air collector, temperatures are reduced and this resulted in improved fuel economy & improved output. Both cylinders & ignition timing could be optimized because exhaust gas temperature differences becomes small. (At 4800 RPM to 7600 RPM, output improved by an average of 1.8%, and fuel consumption improved by an average of 0.4%) The NISMO air collector installation kit includes the intake collector, the necessary vacuum piping for brake & clutch master, and vacuum hose for clutch master, bracket & gasket.This kit is including intake collector, vacuum piping for brake/clutch master, vacuum hose for clutch master,bracket and gasket for installing.

Product Note:

This product cannot be installed with the engine mounted.
Installation of this product will change the characteristics of the engine, necessitating adjustment of the engine control unit. Failure to do so very likely will result in damage to the engine.
The engine improvement figures shown above are based on internal company testing. The actual level of improvement will depend on the engine specifications, conditions of air-fuel mixture and ignition timing, weather and the precision of measurement.
This product cannot be used with single, large-diameter throttle chambers
