GFB Respons TMS Valve (part T9035) - Manual (Page 2)

Installation Instructions for GFB Respons (part # T9035)
The standard base of the GFB Respons T9035 can be mounted in two ways; either as a push fit inside 32-
35mm (1.25 – 1.375”) internal diameter hose, secured with a hose clamp, or by mounting onto a 25.4mm
(1”) outside diameter metal pipe. The supplied recirc outtlet is 30mm. For different mounting options, a list
of the adaptors available is found at the end of these instructions, but if in doubt, check out the adaptors page
on our website
www.gofastbits.com.au , or consult your local dealer.
T9035 is suitable for custom installations, and is also a direct factory replacement for:
•
Subaru WRX/STi MY97-98
•
Nissan 300ZX Z32 (2 valves required)
•
Nissan Silvia/200SX S13 (SR20DET)
•
Nissan Pulsar GTi-R N14 (needs softer spring, part # 6116)
For cars without factory fitted blow-off valves, a
location for the Respons must be found on the
piping between the turbo outlet and the throttle
body, and a suitable adaptor must be welded in
that location. GFB has a range of weld-on
adaptors in aluminium or stainless steel for this
purpose. A hose to connect the Respons recirc
outlet must also be fitted to the piping before the
turbo (after the airflow meter if one is installed).
NOTE: GFB recommends mounting the BOV
closer to the throttle body rather than the turbo,
since some factory turbo piping can cause
pressure
drops which may affect the
performance of the valve. If an intercooler is
used, it is preferable to mount the valve after the
intercooler, before the throttle.
1) Pipe mounting - Once a suitable 25.4mm (1”) O.D. metal pipe has been welded to the turbo piping,
insert the supplied o-ring into the internal groove in the base of your Respons, and partially thread the
M5 grub screws into the tapped holes. Smear a little oil or grease on the o-ring, and slide the valve
onto the pipe. Make sure that the pipe passes fully through the o-ring and bottoms out in the valve
base, and then lock the valve in place firmly with the grub screws. Thread the supplied nuts onto the
ends of the grub screws and tighten – this is to prevent the grub screws working loose.
2)
Hose mounting – Push the base of the Respons into the hose, and secure with a hose clamp. Ensure the
clamp is seated on the straight section of the hose fitting, and not on the retaining bead.
3) Connect the recirc outlet of the Respons to the recirc hose and secure with a hose clamp.
4)
Connect the vacuum nipple on the top of the Respons to a suitable manifold vacuum source (after the
throttle body), using rubber or silicone vacuum hose of at least 4mm I.D. Try to avoid attaching any
other hoses and t-pieces to the vacuum hose and keep it as short as possible, as this will ensure rapid
response from your GFB valve. DO NOT CONNECT THE VACUUM HOSE TO BOOST
CONTROL, FUEL PRESSURE REGULATOR OR BRAKE BOOSTER HOSES.
