    SETTING GUIDE
    ITEM RECOMMENDED SETUP
    BOOST SETTINGS T400M:1.5㎏/cm2（21.3psi）With Boost Controller
    T440M: 1.6㎏/cm2（23.8psi）With Boost Controller
    T400M is designed to output 400ps at 1.5kg/cm2 boost, and T440M is designed to output 440ps at 1.6kg/cm2 boost.
    For normal engines, It is recommended to change metal type gaskets at very least, Because of concerns about gasket loss and engine strength. For normal engines, Approximately 330ps is a guideline for the limit.
    In this case, the boost setting is about 1.0 to 1.1 kg/cm2 (14.2 to 15.6 psi). By replacing the gasket, the upper limit can be set to 1.3 kg/cm2 (18.49psi), by replacing the forged pistons the upper limit can be set to 1.5 to 1.6 kg/cm2 (21.3 to 22.8psi), Please note that this will depend on the condition of each engine．
    When making changes to the boost setting, please do it when you are in 4th/5th gear.
    If you make changes whilst in a lower gear, the load will then be greater at a higher gear, and therefore the boost will be higher than the initial setting.
    (After setting the boost might drop as the rpm rises to peak boost. But don’t be alarmed as this is normal.)
    ACTUATOR SETTINGS Not Required since a boost controller is to be used.
    The wastegate actuator has been pre-set from factory and no further adjustment is required in most cases.
    It is recommended to use a boost controller along with T440M Turbo which helps to maintain stable boost and allows to adjust overall feeling.
    Adjustment of the wastegate actuator should usually only be performed as a sub-adjustment to help boost controller adjustment.
    TARGET POWER T400M:400ps
    T440M:440ps
    For normal engines, Because of concerns about gasket loss and engine strength. Use a max of 300～330ps as a guide at that moment, The setting boost is about 1.1 to 1.2k.
    PISTONS Forged Pistons Recommended: TOMEI Forged Piston Kit
    The stock SR20DET pistons are another weak point that has to be addressed when aiming for more than 330ps.
    When running either T400M, T440M turbos with 1.5～1.6kg/cm boost, the higher the combustion pressure, the higher the risk of the stock Pistons failing.
    {1.3 kg/cm (18.49psi) boost is the max limit of the stock Pistons.
    There has been cases of the engine lasting about a year with the stock pistons.} When running higher boost, together with the upgraded Head Gasket, Forged Pistons are highly recommended.
    CONRODS RECOMMENDED:TOMEI H-BEAM CONRODS
    The original connecting rods can be used, but depending on the engine specifications and driving purpose, the H-type connecting rod is recommended (recommendation: TOMEI H-type connecting rod)
    CAMSHAFT Recommended: TOMEI PONCAM
    With the existing camshafts, you will not get enough exhaust pressure to utilize a larger turbo.
    Replacing to the right camshafts to suit the setup helps the turbo to best perform.
    HEAD GASKET Upgraded Type Required
    Recommended: TOMEI METAL HEAD GASKET
    The higher the boost, the higher the combustion pressure, and there is a risk that the gasket blows off if the factory head gasket is used. To ensure the best sealing performance, it is recommended to replace with a reinforced head gasket with higher surface pressure when running high boost pressures. Depending on the boost pressure, the gasket thickness should be changed to adjust the compression ratio.
    INJECTOR SIZE 630cc or Higher　Recommended: 740cc
    Required injector capacity to suit each setup can be calculated as follows. Target Power(HP) x 5.9 ÷ No. of Cylinders =injector volume (cc) required per cylinder.
    10-20% higher volumed injectors than the amount calculated above is recommended to obtain ideal spray on high rpm range.
    FUEL PUMP 178/h or more (Fuel Pressure 3kg/cm2 )
    Recommended: TOMEI 255 /h
    Required fuel pump capacity to suit each setup can be calculated as follows.
    Injector volume (cc) x No. of Cylinders x 0.06 = Fuel Pump flow rate (L/h) required for the system.10-20% higher rated fuel pump than the amount calculated above is recommended to stabilize the fuel pressure at all time.
    FUEL PRESSURE REGULATOR Adjustable Regulator required. RECOMMENDED ：TOMEI type-S
    Adjusting fuel pressure is required when fuel pump is upgraded.The fuel pressure should usually be adjusted to 3kg/cm2 under the atmosphere pressure.
    AIR FILTER HIGHT FLOW TYPE
    Higher flowing, less restrictive air filter is recommended for a better performance.
    MAF SENSOR Z32 Genuine, or Air Flow Less
    The stock MAF diameter is too small and restrictive. So a common upgrade is the Nissan Z32 MAF sensor swap. With the Z32 MAF it is possible to reach 450p.
    In this case, it is recommended to use a fully adjustable engine management system and go MAF less setup.
    EXHAUST MANIFOLDS TOMEI EXHAUST MANIFOLDS or Similar
    By upgrading your camshafts, you can increase the exhaust pressure, this in turn will help spool larger turbines efficiently once the exhaust manifold has also been changed. All together will aid with the performance increase. Then your larger Turbine will be able to come on boost faster.
    TURBO OUTLET TOMEI TURBO OUTLET or Similar
    The stock outlet pipes will hinder the gas flow efficiency. At higher engine speeds (RPM), these narrower outlet pipes will choke the Turbine exhaust gas flow, causing the boost to be unstable.
    With the larger outlet pipe, exhaust gas flow will be more efficient, boost will stabilize and the efficiency of the Turbo will increase.
    FRONT PIPE Recommended: Pipe Size φ76.3～80 or Similar
    By using a similar sized pipe with the outlet pipe diameter, exhaust gas flow will be smoother, better mid range pick-up and more power in higher RPM range.
    METAL CAT High Flow Type is Required
    By upgrading to a sports metal catalytic converter, you can get the high flow performance needed whilst still meeting the most of the current smog emissions standards.
    EXHAUST Recommended: Main Pipe φ80
    By using a similar sized pipe (φ80～90mm), the exhaust gas flow will be smoother, this will greatly aid to maximize exhaust flow and to prevent any performance restrictions.
    SUCTION PIPE Recommended: Metal Catalytic Converter
    When running at higher boost, the stock suction pipe is not strong enough, so deformation occurs.
    You can improve the intake efficiency by upgrading it.
    INTERCOOLER Large capacity, high flow type
    Compressed air from the Turbo goes into the engine. This process increases the air temperature and lowers density of oxygen in the same volume of air that also lowers the combustion efficiency.
    Supplying the compressed and well cooled air by a better radiating intercooler increases the combustion efficiency that results a better performance and more power.
    BLOW OFF VALVE
    (Recirculation Type)    		 Recirculation type of blow off valve is required.
    Delete the stock air relieve valve system.
    When the Blow Off Valve relieves pressure by venting to the atmosphere, the turbo will work the same as the recirculation method.
    But when the throttle is suddenly closed, air will still continue to flow through the AFM which will confuse the ECU to allow more fuel to be injected into the engine even when there is insufficient air flowing into the engine.
    This will cause the mixture to run rich and cause the engine to stall.
    This fouls the plugs and drops engine performance.
    So when using a blow off valve that re-circulates like standard, this eliminates the problem and allows the ECU to accurately control the correct air/fuel mixture at all times.

    * The S14/15 comes with the Re-circulation Valve for intake relief function. This is when the pressure is higher than the supercharger, and so it acts as a safety device to allow the excess pressure to vent back into the intake system.
    This usually happens when the excess pressure reaches 0.1～ 0.4kg/cm .
    ENGINE MANAGEMENT Optimize the Engines Setup
    ECU tuning to suit each setup is required to optimize the performance and fuel efficiency as well as to protect the engine.
    PLUG UPGRADE REQUIRED Recommended: 8~9 Heat Range
    The stock spark plugs are too low on their heat value for the increased combustion temperature that may cause preignition and cause the spark plug electrodes to melt down and pistons to seize / erode.Recommended plug heat value is usually 8-9, however, the best setup varies engine to engine depending on usage,condition etc.
