Installation Instructions for GFB Respons (part # T9002)

Applicable vehicles:

• Nissan Skyline GTS-T R32-33

• Nissan Skyline GT-T R34

• Nissan GT-R R35 (must use 2 valves)

• Mazda 3 & 6 MPS (Mazdaspeed 3 & 6)

• Mitsubishi Galant VR4

• Mitsubishi Eclipse 1G

1) On the Mazda, first remove the

engine cover to gain access to the
factory bypass valve (figure 1b).
On the Skyline (figure 1a), GTR,
VR4 and Eclipse the valve is
easily accessible.

Remove the two bolts shown in
figures 1a or 1b (item 1), taking
care not to drop them or the
gasket. Open the spring clamp (item 3) and pull the vacuum
hose free, then loosen the clamp on the recirc hose (item 2) and remove the valve from the
car.

3) Fit the GFB Respons valve to the factory mounting flange making sure to use the supplied

gasket between the two. Replace the two bolts, recirc and vacuum hoses and clamps.

Spring Adjustment

Contrary to popular belief, the spring pre-load DOES NOT need to be adjusted to suit different
boost levels. The valve will stay shut under full throttle conditions regardless of boost pressure or
spring pre-load.

Rather, the spring pre-load affects how easily the valve opens
when you lift the throttle, and how long it stays open when it
vents. Adjusting the spring is a simple matter of ensuring the
valve opens enough to release the air, but not long enough to
cause idling problems. The guide below will walk you
through the steps involved.

The screw in the centre of the head is the spring adjuster
(shown opposite). Use the supplied 5mm hex key for this
screw.

The softest spring setting is achieved when the top of the
adjustment screw is 3mm above the head of the valve. Do not set the screw more than 3mm above
the head.
