Can-Am Maverick R P48-415 Turbocharger Upgrade System

Remove the heat shields (2 part) around the turbocharger. 1 hose clamp, (2) 10mm screws underneath and (4) on top by the valve cover.

Unplug the 02 sensor from the engine harness. If you are running a shocker, unplug the actuator plug as well.

Remove the heat shield located on the downpipe. (3) 10mm screws.

Remove the (4) exhaust springs holding the downpipe to muffler. Loosen the V-band clamp holding the downpipe onto the turbocharger. Use a 13mm socket, lightly tap the V-band if stuck. Do not bend this clamp. Remove downpipe.

Remove the turbocharger to intercooler charge tube, (2) 11mm nuts. If you are running a rising rate setup, remove the vacuum line. Remove the intake tube, valve cover breather if not running a catch can, either OEM airbox or high flow intake.

Unplug the electronic wastegate connector. There are (2) tabs, one on top and one on bottom. Press together and remove.

Remove both V-band clamps holding the flex jointer from the header to turbocharger. Take note on where these clamps are orientated. Use a 10mm socket.

Remove the cap off the coolant reservoir. Pinch off all coolant lines going to and from the engine. A total of 5 clamps, going to the head, lines running up to the radiator and intercooler located by plenum, large hose by the temperature sensor, and hose between the firewall and plenum.

CAREFULLY remove the 10mm nut holding the wastegate rod to the flapper. Remove the nut, washer and inner sleeve. USE PB Blaster and let it sit!

Remove (2) 8mm screw holding the wastegate bracket onto the turbocharger.

Remove (2) 10mm turbocharger mounting screws on the bottom. Remove wastegate bracket and rod.

Place a catch pan underneath the vehicle. With the wastegate bracket removed, you can now access the coolant drain plug on the turbocharger. Use a 17mm socket, slowly remove the plug and copper washer.

Remove (4) 10mm screws on the top of the header.

Loosen the bottom pinch plate screws holding the header to the block. You may need to indent the heat shield to get a socket on the screw.

Remove the (2) top 10mm turbocharger screws.

Wiggle the turbocharger off the (2) locating pins while lifting the header up slightly. You do NOT need to remove the header. There is a pipe between the header and turbocharger.

Keep the compensator and (2) gaskets. If torn or bent, you must get new.

Clean up the turbocharger mounting location and gasket. Remove old gasket and replace with supplied gasket. Make sure the compensator tube is bottom out in the exhaust manifold or turbocharger. If not, remove and clean and reinstall with turbocharger. Sometimes they will get pinched sideways.

Install the coolant plug and sealing washer into the turbocharger, torque to 22 ft-lb. This is what you will be sending to Evolution Powersports.

Remove the header and inspect the gasket. If torn, replace. Reinstall header into the pinch plate. Install new turbocharger gasket if you haven’t already.

Install the new turbocharger without wastegate, with the compensator and gaskets. Install all (4) turbo mounting screws. Torque spec below.

Install the wastegate bracket and supplied (2) M8x16mm screws onto the turbocharger. Install the supplied wastegate rod with sleeve, washer and nut onto the wastegate flap. Install the other side of the wastegate rod to the actuator. You will notice the wastegate flap won’t be closed, this is normal.

Spin the compensator gaskets so the tabs are facing the wastegate actuator. If not clocked correctly, the V-band clamps will be clocked incorrectly.

Torque the bottom (3) screws on the clamping plate to 18 ft-lb in sequence.

Install the compensator V-band clamps and hand tighten to now. Make sure the gasket tab is in the opening of the V-band.

Torque the upper exhaust manifold screws to 18 ft-lb, in sequence. Notice the difference between “NEW” and “USED”.

Torque the (4) turbocharger screws to 18 ft-lb in sequence.

Torque the compensator V-band clamps to 80 in-lb.

Remove all the coolant clamps on all hoses.

Reinstall the HFI intake tube.

Reinstall charge tube from intercooler to turbocharger.

Reinstall exhaust and all heat shields. (see photo below)

Check oil levels, may have to add a little.

Add coolant, heat cycle the engine so thermostat opens to top off coolant.

located on the top of the plenum you will find a MAP sensor, remove the electrical connector. With a T-30 socket remove the screw. Remove the OEM MAP sensor. Install dielectric grease on the supplied 4 bar MAP sensor O-ring. Install into the plenum and plug in the electrical connector.

Located on the inside of the throttle body is the second MAP sensor. Remove the charge tube. Unplug the electrical connector, with a T-30 socket remove the screw. Remove the OEM MAP sensor. Install dielectric grease on the supplied 4 bar MAP sensor O-ring. Install the supplied MAP sensor harness to the OEM harness and MAP sensor.

Spray all injector ports and plenum with brake cleaner and compressed air. You do NOT want anything falling into the injector ports. Remove (2) 8mm screws.

Carefully push down and remove the blue safety clip on the fuel quick connector. DON’T BREAK IT. Press down on the top black connector and remove the fuel hose from the fuel rail.

Remove the fuel rail with injectors attached. Flip the fuel rail 180 degrees. Unclip all injector electrical connectors.

ONLY remove the (3) secondary injector clips. Remove injectors and clean O-rings. Install the (3) supplied 1000cc injectors. Use dielectric grease on the O-rings.

Reinstall all other parts in reverse order. No injector adaptors are needed.

Remove the bed and intercooler / radiator wind dam.

Remove both charge tubes from the intercooler using an 11mm socket.

Remove the (1) coolant reservoir mounting screw using a 10mm socket.

Remove the coolant reservoir and bungee it up to the cage.

Remove (6) intercooler tray screws using a 10mm socket.

Tilt the back of the intercooler upwards, unplug (2) intercooler fan connectors. Remove the intercooler from the vehicle.

With the intercooler removed you can now access the valve cover. Unplug (3) coil pack connectors, (3) T-30 screws, and remove (3) coils. With a 14mm socket loosen the spark plugs. Use a magnet to remove the plugs.

Apply a small amount of anti-seize to the threads of the new plugs. Install the plugs into the head using a magnet. Torque the plugs to 124 in-lb (14 Nm).

Once complete, reinstall vehicle in reverse order.
