Section 2: Removal Procedure
Preparation for Removal of Stock Intake Manifold
•
Before you begin make sure the fuel in your tank has
been completely switched over to premium 91
octane. This is necessary to avoid any pinging once
the supercharger has been installed.
•
Magnuson recommends that you thoroughly clean
the engine and engine compartment. If you don’t,
grease buildup on parts could become dislodged
during the procedure and fall into the engine.
•
Make sure the engine has cooled fully before you
begin.
•
To help you later, we suggest you draw diagrams of
your engine’s cable routing before you disconnect
anything. You can do the same for the vacuum hoses;
however, some of the vacuum connections on your
stock manifold may not be the same as those on the
supercharger. To ensure the proper hose
connections, refer to the diagrams in the back of this
manual.
•
The Magnuson supercharger kit has been designed
to reuse most of the stock nuts and bolts. Therefore,
as you remove them, keep them with their
components or label them for location. This will
assure a faster, easier installation.
Figure 1
A. Removal of Stock Intake Manifold (figure 1)
1. Disconnect the battery ground cable.
Figure 2
Page 3
2. With tape or a permanent marker, mark the forward
edge of the power steering and the air conditioning
compressor drive belts (figure 2). This will ensure
that the belts will be returned to their original
positions and that they will rotate in the same
direction. If you reverse the direction of rotation, it
may cause the belts to fray.
MAGNUSON INSTALL MANUAL
TOYOTA 3.4L MY 1996 - 2004
3. If equipped, remove the gravel guard from beneath
the radiator (figure 3). This will give you access to the
A/C belt adjuster.
TIP: The grave l gu ard consists of two pieces
but it’s m uch easier to install if you remove it
as a one‐piece assem bly.
4. Loosen the pinch nut in the center of the A/C
compressor belt pulley and loosen the adjuster bolt
enough to loosen the belt (see arrow, figure 4).
5. Using an angled flat ratchet, loosen the pinch nut and
adjuster bolt for the power steering pump.
6. Remove the two belts.
7. Loosen the alternator pivot bolt (top), pinch nut and
adjusting bolt and remove the alternator belt. During
the installation procedure, it will be replaced with a
belt supplied with the supercharger.
8. Loosen the air intake tube clamps at the throttle
body and disconnect the Mass Air Flow Sensor plug.
CAUTION: The air sensor (see pointer, figure 5) is
fragile so be careful when working around it.
Figure 4
Figure 5

MAGNUSON INSTALL MANUAL
TOYOTA 3.4L MY 1996 - 2004
9. Remove any connections from the air intake tube
and remove the tube (figure 6).
10. Some trucks are equipped with one or two Vacuum
Switched Valve (VSV) assemblies. To locate yours,
consult the appropriate diagrams at the end of this
manual. If the valve is mounted on the rear of the
engine, it should be relocated to the firewall with the
supplied bracket.
Figure 6
Figure 7
Figure 8
Page 5
11. Note the tension and adjustment of the throttle
cable and the transmission throttle‐pressure (kick
down) cable (if equipped with an automatic
transmission). You will need to re‐create these
adjustments during the assembly procedure. To help
you remember, look for the small metal bead (the
stake stopper, automatic transmission only) on the
kick down cable (see arrow, figure 7). If the cable is
properly adjusted, the bead should be flush with the
end of the cable’s rubber sheath (see arrow, figure
8).
MAGNUSON INSTALL MANUAL
TOYOTA 3.4L MY 1996 - 2004
TIP: If your vehicle is equipped with cruise
control, do not remove the cruise cable from
the throttle body. If you do, you will have to
readjust it later.
12. Loosen but don’t remove the cable nuts (figure 9).
Slide the cables from their brackets and remove the
cable ends from the throttle‐body levers.
13. Unplug the throttle‐position sensor connector (A)
and the IAC (Idle Air Control) valve connector (B) (see
arrows, figure 10).

TOYOTA 3.4L MY 1996 - 2004
14. Remove vacuum lines from the throttle body but
don’t remove the two coolant hoses (figure 11).
TIP: The coolant hoses have clam ps (see arrows, figure
12).The vacuum hoses do not.
15. Remove the throttle body with attached coolant
hoses and cruise control cable (if equipped) and set
to the passenger’s side (figure 12).
Figure 11
16. At the driver’s side of the engine, remove the
diagnostic plug from its mounting bracket (upper
arrow, figure 13) and set it aside. Remove the bolt
and bracket that holds the diagnostic connector to
the stock manifold and save for reassembly. Remove
the ground wire and move it to one side (lower
arrow, figure 13).
17. Remove the vacuum hoses for the power brake, PCV
and EVAP from their tubes on the upper manifold.
Figure 12

TOYOTA 3.4L MY 1996 - 2004
18. A pre‐2000 Tacoma or T‐100 may be equipped with
an EGR valve. To be sure, look for this tube (see
arrow, figure 14) on the driver’s‐side exhaust
manifold. Remove the valve according to the
procedure in Section 4. Note that the valve will be re‐
installed later in the installation procedure.
19. Remove the bolt holding the manifold to the intake
chamber stay (see arrow, figure 30). Save the bolt.
20. Remove the nuts and bolts from the upper half of the
intake manifold and set it aside (figure 15).
Figure 14
21. Remove the 2 bolts and disconnect the fuel‐return
line bracket (but don’t disconnect the fuel hose)
from the driver’s side of the lower manifold and
remove the bolt from the wire‐loom bracket.
22. Remove the bolts and nuts from the lower manifold.
TIP: The nuts at the far ends of the manifold will
be reused during installation. To avoid losing
them, pick them up with a magnet.
23. Remove the lower manifold (figure 16) and save the
factory nuts, washers and two short bolts, as they
will be reused.
Figure 15
24. Inspect the gasket. If it is in good shape, reuse it; if
not, replace it with a new one (Toyota part # 17176‐
62040).
Note: The gasket between the surge tank and the
manifold (figure 15) is intercangable for use as the
supercharger’s intake manifold gasket (see section
B‐2).
Figure 16

25. Tape over or cover the engine manifold ports to keep
out debris (figure 17).
26. Using the template supplied and a scribe or marker,
mark the top of the timing belt cover around the
template (figure 18).
27. Move any wires out of the way and with a coping saw
blade or flexible saw, cut along the scribe mark
(figure 19) and discard the cut‐out piece. This cut
away will provide the clearance for the drive housing
of the supercharger.

B. Installation of TRD Supercharger and
Manifold Assembly
1. (Skip this step for 2001 and newer 4Runner) Cut the
hose leading to the IAC valve connector at the
location shown, and insert the kit’s one‐way valve
into the straight part of the hose. The black end of
the valve (see arrow on figure 25 and diagrams at the
end of this manual) is closest to the throttle body.
IMPORTANT: The IAC hose and the coolant hoses are
similar in size. Don’t cut the wrong one. The coolant
hoses have clamps, the IAC hose does not.
Figure 25
2. Remove the tape from the intake manifold and
reinstall the stock gasket.
3. Lower the supercharger and manifold into place
making sure there are no hoses or wires in the way.
The ignition wires should be routed beneath the
supercharger’s drive housing (see arrow, figure 26).
4. When the assembly sits flat on the engine, put the
stock manifold brace (driver’s side) bolt and supplied
spacer in first (see arrow, figure 27) and then install
the stock nut so the studs at each end of the
manifold and hand tighten. Use M8x35mm Bolt
5. Install the supplied long manifold bolt (8x 1.25x
170mm) through the supercharger to the stock
manifold followed by the two stock bolts. Alternating
from one side to the other, torque the bolts and two
nuts to the specs provided in the Toyota Repair
Manual.
NOTE: In step #1 above, the valve in your kit may not
have a black end. You can determine the flow
direction by gently blowing air through it. The valve
needs to be installed so that the flow goes into the
engine.
Figure 27

6. Place the drive belt over the water pump pulley, the
crankshaft pulley and the alternator pulley (figure
28). Make sure the belt is on the correct sides of and
properly seated in the grooves of each pulley.
7. To assist in belt installation, using a 3/8" long handle
ratchet (figure 29), pull down in direction of arrow to
provide slack on belt.
8. Install the power steering and A/C belts according to
the marks you made before removal (see section 2,
figure 2, page 2).
9. Install the supplied dipstick relocation bracket (see
arrow, figure 30) utilizing the factory bolt. Reinstall
the factory dipstick and attach it to new bracket
using the supplied bolt (6mmx 1.0x 12mm).
Torque both bolts to 10ft./lbs.
NOTE: Be sure to maintain proper dipstick tube seal
at oil pan. Check rubber grommet at end of dipstick
tube for engagement.

install it now according to Section 4.
2.
Using the gasket, OE Fasteners, install the throttle body
on to the supercharger’s manifold.
A
Figure 31
IMPORTANT: Do not reuse the OE metal gasket (A,
figure 31) on the throttle body. It will reduce boost
output by 1 ½ lbs. Use the gasket supplied with the kit
(B, figure 31), and make sure that it is positioned
properly. Its shape must coincide with that of the
throttle body. If not, you will create a vacuum leak.
2. Torque each bolt to the specs provided in the Toyota
Repair Manual. Do not overtighten.
3. Install the throttle position sensor plug, the coil plug (if
removed), and the IAC valve connector.
4. Attach the PCV hose to the PCV valve on the passenger’s
side of the engine.
5. Install the air inlet tube to the throttle body and Mass
Air Flow Sensor and reconnect its hoses and tubes. Be
careful not to damage the sensor (figure 32).
6. Install the proper cable bracket to the top of the
manifold. Three throttle cable brackets are supplied
with this kit. The bracket with only one U‐shaped cable
mount should only be used on Tacoma 4WD manual‐
transmission vehicles. The bracket with two U‐shaped
cable mounts should be used on all other models except
2001 and newer 4Runners. For 2001 and newer
4Runners, use cable bracket number 00602‐17620‐080.
7. Remove the transmission cable clamp from the
manifold support. Clamp is no longer needed.
8. Remove the throttle cable/evaporative canister hose
bracket and bolt from the stock manifold. Install the
bracket on to the supercharger as shown (see arrow A,
figure 33). Insert the throttle cable and evaporative
canister hose, and install the Zip Ties on the throttle
cable and evaporative canister hoses as shown (see
arrows B, figure 33).

21. Drive test the vehicle. Listen for any unusual noises,
vibrations, or engine misfires. The supercharger does
have a slight whining noise under boost conditions,
which is normal. Listen for engine detonation
(pinging). If any detonation is heard let up on the
throttle immediately. Most detonation is caused by
low octane gasoline still in the tank. Premium fuel is
required.

Section 4: EGR Removal and Installation
If your Tacoma or T‐100 is equipped with an Exhaust Gas
Recirculation (EGR) valve (see arrow, figure 42), you
will need to remove the valve from the stock intake
manifold and reattach it to the Magnuson
supercharger manifold. Here’s how:
A. Removal
1. Loosen the EGR pipe from the driver’s side exhaust
manifold. This will ease the removal and installation
procedures (figure 42).
Figure 42
2. Loosen or remove the clamp holding the pipe to the
back of the engine.
3. Remove the two nuts holding the EGR pipe to the
EGR valve and separate the two.
