The ARMS M7960 is capable of 400PS with 1.6k of boost.
The stock engine is safe for 360-370PS due to the weak Conrods. So with the standard engine it is best to use 1.4~1.5K of boost.
Change the boost settings whilst you are in 4th or 5th gear.
If you adjust boost settings in lower gear, then your boost settings will be higher when you are running in higher gears. (i.e setting theboost to 1.5K in 1st or 2nd gear can result to 1.7K in 4th or 5th gear).
(It’s not abnormal to see on some occasions when the rpm raises from peak boost and the boost drops). It is not necessary to modify the actuator from its original setting.
The actuator is designed to protect the turbine from the excessive boost pressures by relieving the excessive boost by opening the bypass valve.
The boost controller is connected with the actuator and intake plenum and it controls the amount of pressure that will go to the actuator to control the actuator.
So the boost controller will allow you to adjust the boost pressure that will determine when the actuator will open of close the relief valve.

| ■ EXPECTED POWER |
STANDARD ENGINE |
360~370ps |
| TUNED ENGINE 2.2L/ 2.3L |
400~420ps |
The stock engines Conrods are not that strong so the limit with the standard Conrods is about 360~370PS so it is best to keep the power below that with max boost being 1.4~1.5K.

■ INJECTOR SIZES
|
STANDARD ENGINE |
620cc or higher
Recommended: TOMEI 700cc |
| TUNED ENGINE 2.2L/ 2.3L |
680cc or higher
Recommended: TOMEI 700cc |
To work out the injector sizes you need you use this formula,
Target Horsepower x 5.9 ÷ No. of Cylinders = the cc flow amount per cylinder required. Take into account that you will run up to 80%~90% of the injector’s capacity.
|
|
■ FUEL PUMP
|
STANDARD ENGINE |
165L/h or higher (Fuel Pressure 3kg/cm²)
Recommended: TOMEI 255L/h (Fuel Pressure 3kg/cm²) |
| TUNED ENGINE 2.2L/ 2.3L |
182L/h or higher (Fuel Pressure 3kg/cm²)
Recommended:TOMEI 255L/h (Fuel Pressure 3kg/cm²)
|
 To work out the fuel pump size you need you use this formula,
Injectors Capacity x No. of Cylinders x 0.06 = Fuel Pump flow rate required. Then consider that the fuel pump should be used at 80~90% capacity when making your choice.

■ FUEL PRESSURE
REGULATOR
|
STANDARD ENGINE |
Upgrade Required
Recommended: TOMEI Type-S |
| TUNED ENGINE 2.2L/ 2.3L |
Upgrade Required
Recommended: TOMEI Type-S |
 Changing the fuel pump will require you to adjust the fuel pressure with an adjustable fuel pressure regulator to suit the new setup. You will need to set it at 3k when idling without the vaccum hose being connected.
|
|
| ■ SPARK PLUG HEAT RANGE |
STANDARD ENGINE |
Required Best to use Heat Range #8~9 |
| TUNED ENGINE 2.2L/ 2.3L |
Required Best to use Heat Range #8~9 |
With the increase of horse power, the increase in combustion temperatures and this will be a risk of the plugs from melting. The recommended plug heat range of 8-9 is suitable.
|
|
■ BLOW OFF VALVE
|
STANDARD ENGINE |
Best to upgrade.
Recommended: TOMEI Strenghtened Blow Off Valve |
| TUNED ENGINE 2.2L/ 2.3L |
Best to upgrade.
Recommended: TOMEI Strenghtened Blow Off Valve |
 The stock blow off valve is not strong enough to cope with the pressure on higher boosted applications so the TOMEI blow off valve will retain the recycling type feature and will adequately control the pressure on high power setups.
The stock blow off valve will at times not function effectively when needed depending on the boost settings so stabilizing the boost settings is not possible.
But without the blow off valve the turbo will fail. To protect the turbo the blow off valve becomes an important component on your investment and the TOMEI strengthened blow off valve is suitable to meet everyone’s budgets and to meet your needs.
This is an essential component for those who will upgrade their turbo and run higher boost.

■ CAMSHAFTS
|
STANDARD ENGINE |
TOMEI PONCAM SUITABLE |
| TUNED ENGINE 2.2L/ 2.3L |
TOMEI PONCAM SUITABLE or higher |
 Running larger profile camshafts will increase the exhaust back pressure.
This will help with spooling the turbo for improved peak power gains. |
|
■ EXHAUST MANIFOLDS
|
STANDARD ENGINE |
TOMEI EXPREME SUITABLE |
| TUNED ENGINE 2.2L/ 2.3L |
TOMEI EXPREME SUITABLE |
 When upgrading the camshafts to optimize the turbos performance it is best to also upgrade the exhaust to maximize the performance potential of the setup. With the EXPREME exhaust manifold design the exhaust backpressure will be improved to give you an easier and sharper turbine spool. |
|
■ OUTLET/ FRONT PIPE
|
STANDARD ENGINE |
TOMEI EXPREME SUITABLE |
| TUNED ENGINE 2.2L/ 2.3L |
TOMEI EXPREME SUITABLE |
The standard outlet pipe is not suitable for exhaust flow.
The exhaust will clog the exhaust gases with high speed, high boost due to the narrow pipe diameter which causes a bottleneck effect. This will drop the turbines efficiency due to the restrictions on the exhaust flow hindering boost capabilities.
So with the larger diameter pipe, the exhaust flow will be optimized which will maximize the Turbo’s and engines performance with a good stable boost control.
|
|
| ■ MUFFLER |
STANDARD ENGINE |
Recommended: Main Pipe Diameter Ø80 SUITABLE |
| TUNED ENGINE 2.2L/ 2.3L |
Recommended: Main Pipe Diameter Ø80 SUITABLE |
As with the TOMEI outlet pipe design a larger diameter design with smooth internal design to maximize exhaust flow and not cause any performance restrictions.
|
|
| ■ CATALYTIC CONVERTER |
STANDARD ENGINE |
Recommended: Metal Catalytic Converter |
| TUNED ENGINE 2.2L/ 2.3L |
Recommended: Metal Catalytic Converter |
With the use of a high flow performance Metal Catalytic Converter you can increase the performance with increasing the exhaust flow.
|
|
■ HEAD GASKET
|
STANDARD ENGINE |
Change to Metal Gasket Type
Recommended: TOMEI Metal Gasket |
| TUNED ENGINE 2.2L/ 2.3L |
Change to Metal Gasket Type
Recommended: TOMEI Metal Gasket |
 When increasing boost and with the increase of combustion pressure the standard head gasket limit is soon realized. By using the correct metal gasket thickness you can adjust and obtain the required compression ratio and increase durability to cope with the increased power output of the engine. |

| ■ INTERCOOLER |
STANDARD ENGINE |
Standard ~ Bolt on upgrade |
| TUNED ENGINE 2.2L/ 2.3L |
Standard ~ Bolt on upgrade |
Pressurized air in the turbine is sent to the engine compressed. Compressed air will expand with heat.
With the drop in air density the performance efficiency will also drop due to poor combustion.
With the intercooler fixed in between the engine and turbine the compressed air will be air cooled to eliminate heat.
Combustion efficiency will be improved with the cooled compressed air being forced into the engine intake resulting in performance gains.
|
|
| ■ AIR CLEANER |
STANDARD ENGINE |
Recommended: High Flow OEM Upgrade type. |
| TUNED ENGINE 2.2L/ 2.3L |
Recommended: High Flow OEM Upgrade type. |
Running the standard air cleaner is recommended when using an AFM (air flow meter) .

| ■ SUCTION PIPE |
STANDARD ENGINE |
Any Decent Aftermarket Type |
| TUNED ENGINE 2.2L/ 2.3L |
Any Decent Aftermarket Type |
The standard suction pipe can at times deform and or restrict flow with high boost conditions.
By upgrading this component added benefits can be gained.
