Fitment Information

• Nissan Skyline R31 GTS-Turbo RB20DET (1985, 1986, 1987, 1988, 1989, 1990) GTS-Turbo only, does not fit non-turbo R31 variants
• Nissan Skyline R32 GTS-T RB20DET (1989, 1990, 1991, 1992, 1993) GTS-T only, does not fit R32 GT-R
• Nissan Skyline R33 GTS-T RB25DET (1993, 1994, 1995, 1996, 1997, 1998) GTS-T only, does not fit R33 GT-R
• Nissan Skyline R34 GT-T RB25DET (1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006) GT-T only, does not fit R34 GT-R

Fitment Note: Fits the single-turbo GTS-T and GT-T Skyline variants with RB20DET and RB25DET engines only. Does not fit the R32, R33, or R34 GT-R, which uses the twin-turbo RB26DETT engine and requires a different BOV setup with two valves and different flanges. 

Specs & Features

• 3 Valves in one, diverter valve/ BOV
• Dual staged venting outlets, can be configured for full recirc, 50/50, or full atmosphere operation using plugs provided.
  
• TMS Technology for up to 30% faster boost recovery on gearshift.
  
• Huge range of direct bolt-on kits.
  
• 100psi+ boost holding ability.
• This item does not ship to California
• The T9208 Hybrid is the original GFB dual-port blow-off valve, first developed in 1998, and is designed specifically to solve the stalling and backfiring issue that a pure atmosphere-venting BOV causes on MAF (Air Flow Meter) equipped vehicles such as the RB20DET and RB25DET.
• The staged venting design opens the recirculation port before the atmosphere port so that partial recirculation occurs even during an atmosphere vent event, preventing the lean spike that destabilises the AFM fuelling signal.
• Three venting configurations are possible using the supplied plugs: full recirculation for silent diverter operation, the default 50/50 hybrid configuration for a blend of performance and sound, or full atmosphere for maximum blow-off sound.
• TMS Technology delivers up to 30% faster boost recovery on gearshift compared to the factory diverter valve.
• Boost holding capacity exceeds 100 PSI.
• Direct bolt-on to the OEM BOV location, no modifications required. 

OEM Part Numbers

• R32 GTS-T RB20DET BOV assembly: Nissan 14956-05U00 (confirmed OEM diverter valve / BOV for R32 GTS-T RB20DET application)
• R33 / R34 GTS-T / GT-T RB25DET BOV assembly: Nissan 14956-24U00 (confirmed OEM diverter valve for RB25DET single-turbo application)

These OEM part numbers confirm the factory BOV that the T9208 replaces on each platform. The R31 GTS-Turbo OEM BOV part number was not available from verified sources at the time this listing was created. Buyers can verify using the Nissan parts catalog with their VIN or chassis number.

Pairs well with:

• Rev9 Front Mount Intercooler Kit Nissan Skyline R32/R33 GTS-T RB20DET/RB25DET A front mount intercooler upgrade to complement the BOV replacement on GTS-T and GT-T builds, reducing intake air temperatures and supporting higher boost levels where a performance BOV delivers the most benefit.

In a time before Justin Bieber, Y2K, and even Google, the year is 1998 and GFB’s founding engineer John Adrian is so sick of his new WRX stalling with an atmosphere-venting BOV he decided he didn’t want to live in a world any longer without a dual port BO…so he invented it!

Known as the “Hybrid”, this world-first became the flagship model of the newly formed company Go Fast Bits. The two venting ports of this revolutionary valve were staged on the body such that the recirc port opened before the atmo port, helping to prevent backfiring and stalling on cars with a MAF sensor, whilst still giving the signature blow off sound when the car is driven harder.

This innovation was so successful that the technology has since been adopted by almost every other BOV brand on the market. The Hybrid then went on to evolve into GFB’s next world-first, the venting bias adjustable BOV now known as the Respons TMS, and then to the electronically adjustable version, the Deceptor Pro.

With the spotlight focused on these current products, the Hybrid has been absent from the market for some time, but in celebration of the 20 years since the invention of one of the most influential BOVs the turbo world has seen, GFB is bringing the Hybrid back!

And as a fitting birthday present, the importance of the dual-port venting system and the new Hybrid valve was recognized from a field of 3000 entries by a panel of international judges and presented with a Global Media Award at the 2017 SEMA show.

With the same staged venting outlets as the original, but now with the ability to configure for full recirc, full atmosphere, or 50/50 venting, and a huge range of direct bolt-on kits for popular vehicles, the new Hybrid offers all the benefits of dual port venting, at an affordable price.
