------------------------------------------------------------------------------------------------------------------------
BEFORE YOU START –IMPORTANT NOTES
Turbosmart recommends that your E-Boost Street is fitted by an appropriately qualified technician.
Consult your local tuning specialist before setting your boost pressure as setting boost beyond your engines capability can result in
severe engine damage or failure
Turbosmart recommends that the engines Air/Fuel ratio is checked once the desired boost pressure is set. Any increase in boost
pressure can cause the engine to run lean resulting in severe engine damage or failure
Turbosmart recommends that the E-Boost Street is not used in conjunction with any type of “Draw Through” induction System.
Turbosmart recommends that boost pressure is set using a Dynamometer and not on public roads.
The E-Boost Street may not be able to completely compensate for a drop in boost pressure at high RPM due to the turbocharger
operating beyond its maximum efficiency range i.e. incorrect turbocharger sizing or excessive exhaust backpressure.
The E-Boost Street cannot compensate for increases in boost pressure at high RPM due to inadequate waste gate flow capacity;
the turbo system must maintain a steady base boost curve before you start using a boost controller.
The E-Boost Street cannot be used with external waste gates that are in a poor, worn or non-serviceable condition.
For best results your turbocharger should be correctly sized for your application.
Erratic operation of electronic parts can be caused by Electro Magnetic Interference (EMI). EMI can be generated by aftermarket
ignition systems such as CDI which, if wired incorrectly, generate large amounts of EMI through the vehicles electrical system. This
can cause items such as ECU’s and boost controllers to be effected. Please follow ignition system installation instructions VERY
carefully to avoid EMI affecting the E-Boost Street. Sometimes, using resistor type spark plugs can reduce this problem.
The E-Boost Street is not waterproof and must be mounted inside the cabin. The unit has an operating temperature range of -5OC
to 70OC.

INSTALLATION
Wiring
(Solder all wires together and insulate the joints with the supplied heat shrink)
Note: Unused wires must be insulated with electrical tape so that they do not touch other wires or the chassis
Red Wire –+12 Volts switched through ignition –connect via 5 Amp fuse supplied
Black Wire –Chassis, earth or ground
Yellow Wire –To 3.5V –12V Square wave (RPM) Signal OPTIONAL
Green Wire –External set point switching (Ground to activate) OPTIONAL
Orange Wire –Dimming trigger (Ground to activate) OPTIONAL
White Wire –Auxiliary Output (Negative switched) OPTIONAL
Brown and grey wire –to boost control solenoid (Polarity not important)
RPM Signal Connection (OPTIONAL)
RPM signal connection is ONLY for Tacho mode, RPM set point mapping, Boost correction, shift light function and other advanced
features. Turbosmart recommends your RPM signal be connected by an appropriately qualified technician or automotive electrician. For
further information consult your vehicle’s manuals or your local automotive electrician. The E-Boost Street is ONLY able to accept an
RPM signal in the form of a square wave that is switching between 0V and 3.5-12 volts.
The following points should be followed to connect your RPM signal to an ECU pin.
- Locate your ECU RPM signal wire and splice into the signal wire coming from your ECU.
- Check the output you are splicing into is a square wave that is switching between switching between 0V and 3.5-12 volts with an
appropriate meter.
- Connect the yellow RPM wire from the E-Boost Street to the spliced section of the ECU RPM out.
- Turn on the E-Boost Street and configure your signal to the number of cylinders or rotors your engine has using the CYL (cylinder)
parameter located in the setup menu.
- In live mode with your engine running press mode once to show live RPM. The display should be reading RPMx100 e.g. 015 on
the display indicates 1500 RPM. If the display is not reading correctly re-check the cylinder configuration in the setup menu.
- Note: If the OEM tachometer does not display RPM after installing the E-Boost Street, a 2 ohm or higher resistor needs to
be installed in line between the ECU RPM output pin and the E-Boost Street.
The following points should be followed to connect your RPM signal to the negative terminal of an ignition coil. NOTE: Caution should
be exercised when connecting to the negative terminal of an ignition coil and Turbosmart recommends an ECU connection where
possible. IMPORTANT! The RPM signal should not be connected to a coil of a capacitive discharge ignition (CDI) system.

- Check the signal from the negative terminal is a square wave that is switching between switching between 0V and 3.5-12 volts with
an appropriate meter. If the voltage is below 3.5V (coil trigger signals tend to have a very low voltage) the e-Boost will not read a
signal. In this case, a signal amplifier (also known as a tach adapter) must be used to boost the signal.
- Connect the RPM signal wire from the E-Boost Street to the negative terminal of an ignition coil or tach adapter (which ever
method is used).
- Turn on the E-Boost Street and configure your signal to the number of cylinders or rotors your engine has using the CYL (cylinder)
parameter located in the setup menu
- In live mode with your engine running press mode once to show live RPM. The display should be reading RPMx100 e.g. 015 on
the display indicates 1500 RPM. If the display is not reading correctly re-check the cylinder configuration in the setup menu.
Vacuum/pressure signal
The E-Boost Street requires a vacuum/pressure signal from the intake manifold to function. A combination of poly tube and silicone
hose is used to connect the E-boost Street to a adequate vacuum/pressure signal. Route the poly tube from the E-boost Street
head unit through the fire wall approximately 100mm (4”) only as the poly tube is not rated to the high temperatures of the engine
bay.
Use the connecting barb to join the poly tube to the 3mm ID silicon hose at the firewall/bulkhead. Ensure the poly tube is pressed
all the way onto the connecting barb
Route the silicon hose through the engine bay and connect it to a pressure/vacuum signal from the inlet manifold. Use the supplied
tee piece if necessary.
Secure all connections with the supplied hose clamps
Installing the E-Boost Street Solenoid
- The E-Boost Street solenoid is rated to a maximum temperature of 100
degrees Celsius (212 degrees Fahrenheit), ensure that it is mounted a
minimum of 250mm (10 Inches) away from the heat of the turbo or
exhaust manifold, otherwise heat shielding maybe required.
- Mount the E-Boost Street solenoid in an appropriate position in the
engine bay with the mounting kit supplied.
- Fit the rubber grommet inside the mounting plate. Slide the sleeve
inside the grommet. Use the M3 screws to bolt the solenoid to the
mounting bracket –Note use loctite on the threads to secure. Use the
M6 screw, washer and Nyloc nut to mount in a suitable location in the
engine bay.
- The E-Boost Street head unit is capable of controlling two solenoids. The use of twin solenoids is not necessary but is
recommended in twin turbo setups on V configuration engines as this reduces the length of hose required for plumbing which aids
in response and control of the wastegates.
- The solenoid must be connected to a pressure only source which must be located before the intercooler, ideally off the compressor
cover of the turbocharger. The air temperature before the intercooler is less affected by ambient conditions which will give you
more consistent boost control.
SOLENOID HOOK UP METHODS
WARNING! Changing to different connection method can cause a higher than expected increase in boost pressure. Turbosmart
recommends adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by
the new setup before increasing your boost again.

5
Note: If your vehicle is fitted with a factory boost control solenoid, the hoses that run from the pressure source and to the
wastegate actuator must be disconnected. Leave the solenoid plugged into the wiring loom so that the ECU is not affected.
Failure to disable the factory boost control solenoid and hoses will result in erratic or fluctuating boost pressures which could
damage your engine.
INTERNAL WASTEGATE CONNECTION
WARNING! Changing to different connection methods can cause a higher than expected increase in boost pressure. Turbosmart
recommends adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure achieved by
the new setup before increasing your boost again.
Note: If your vehicle is fitted with a factory boost control solenoid, the hoses that run from the solenoid to the pressure source
and to the wastegate actuator must be disconnected from the solenoid. Leave the solenoid plugged into the wiring loom so
that the ECU is not affected.
Most factory turbocharged vehicles use an internal waste gate system to control boost pressure. The E-Boost Street controls boost
pressure by controlling the pressure signal that the waste gate actuator receives from the turbocharger. Please note that the E-Boost
Street cannot be used to obtain a boost pressure lower than the standard waste gate actuator’s pressure setting.
Some factory hoses have a small restrictor fitted inside them, if the factory hoses are reused over boosting or boost spiking may
occur.
Secure all connections with hose clamps.
Single solenoid, single turbocharger hook up(Basic single internal wastegate setups)
Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet
of the turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris
entering the solenoid.
Port (2): to the internal wastegate actuator
Port (3): to pressure only source
If you are unable to achieve your desired boost pressure, it is normally due to exhaust manifold backpressure forcing the internal waste
gate to open. To increase your boost pressure further, fit a higher pressure waste gate actuator to increase your minimum boost
pressure.
WARNING! Fitting a higher pressure waste gate actuator may cause a higher than expected increase in boost pressure.
Turbosmart recommends resetting the boost set point values to Zero and measure the new minimum boost pressure before increasing
your boost set point values.
Internal wastegates with 2 ports
Port (1): vents pressure from the solenoid.
Port (2): connect to one of the ports of the actuator

Single solenoid, twin parallel turbocharger hook up
(For straight configuration twin parallel turbocharger engines E.g. RB26DETT)
The E-Boost Street is capable of controlling twin internal wastegate turbochargers with a single solenoid.
This method is used when the turbochargers are mounted close to each other allowing the solenoid to be mounted close to both
actuators
Each solenoid port is connected as follows:
-Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet of
the turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris entering the
solenoid.
-Port (2): to tee piece that feeds both actuators
-Port (3): to pressure only source
Twin solenoid, twin parallel turbocharger hook up
(For V configuration twin parallel turbocharger engines E.g. V6, V8 etc)
The E-Boost Street is capable of controlling two solenoids for twin parallel turbocharger setups.
This method is used when there is a great distance between the wastegates. This allows the solenoids to be mounted close to the
wastegates to minimise the length of hose used and to maximise response
You will need a second solenoid for this method (TS-0301-3003)
Connect the grey wire from the e-Boost wiring loom to one of the wire from each solenoid.
Connect the brown wire from the e-Boost wiring loom to the remaining wire from each solenoid.
Each solenoid port is connected as follows:
-Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet of
the turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris entering the
solenoid.

EXTERNAL WASTEGATE CONNECTION
The first method of installation is a one port connection. If the desired boost level is not achieved i.e. boost level is too low, or not
controllable, it is recommended that the wastegate spring be changed to a spring which is closer to the desired boost pressure or to trial
a 2 port connection method.
There are 3 different 2 port connection methods that can be trialled to achieve different results. The 2 port method (1) can be used if
there is high exhaust manifold back pressure forcing the valve open. The 2 port method (2) allows the user to achieve the maximum
boost pressure their turbo system is capable of. If a wide range of boost pressures is desired i.e. 5 –40 PSI, the 2 port method (3) with
a 4 port solenoid (sold separately –TS-0301-2003) might be needed.
A single solenoid can be used to control twin wastegates in a twin turbo setup but it is recommended that twin solenoids are used in
twin turbo setups to reduce the length of the pressure hoses to aid in control and response of the wastegates.
