GFB 09+ Nissan GTR TMS Respons Twin Valve Blow Off Valve Kit
Part #: T9202
As the name suggests, the GFB Respons is designed specifically with the aim of improving throttle response and reducing turbo lag.

Whats TMS? GFBs Turbo Management System is the term we apply to our diverter valves that have features designed specifically for the purpose of turbo lag reduction.

Tests show that TMS features can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

On top of the TMS benefits, the Respons also packs GFBs patented adjustable venting bias system found on the Stealth FX.

This unique system allows the amount of air vented to either recirc or atmosphere to be infinitely varied to change the venting sound like a stereo volume dial!

So if you want noise with your performance, the Respons can deliver! By fine-tuning the venting ratio, you CAN achieve a blow-off sound WITHOUT throwing a CEL, running rich, stalling, using more fuel or causing any other problems commonly associated with atmo-venting valves on cars with MAF sensors.

Available in a range of universal hose-mount or direct bolt-on configurations for many popular models.

*Features*
* Advanced TMS benefits
* Spring pre-load adjustment for max. response
* Available as universal or direct-fit kit
* Venting configurations:
- Full progressive bias adjustment from recirc (silent) to atmosphere (loud)
- Bias adjustment done manually via cap ring
- C an be locked off in full recirc mode for legality purposes

*Best choice for:*
* Quick and easy venting bias adjustment
* A chieving noise on a car that is sensitive to atmosphere venting e.g. VAG applications

Go Fast Bits 3 pc Lightweight Pulley Kit - Subaru BRZ/Scion FR-S
Part #: 2016
GFB Pulley Kit: GFB lightweight pulley kits are made from aircraft-grade 6061-T6 aluminium and offer faster acceleration through significant weight reduction on the crankshaft. The effect is similar to a lighter flywheel, and the car feels more lively and willing to rev.

Most of our kits are underdriven, which means the accessories are driven slightly slower to reduce parasitic losses. It should be noted that our underdrive pulley kits do NOT adversely affect the operation of the accessories. If they did, we would not sell them!

*Features*
* Improved throttle response and acceleration through significant reduction of rotating mass
* Engine feels more free-revving
* Under-driven kits offer more power through reduction of parasitic losses from the accessories with NO adverse affects on their operation

Go Fast Bits Alternator Pulley: Subaru
Part #: gfb.2201

Product Details: GFB's pulleys are manufactured on the latest Multi-Axis CNC machines from the highest grade 6061-T6 aluminium billet, making them immensely lighter than their factory steel counterparts. This lower weight yields a large reuction in the rotating inertia of the belt train, allowing the engine to accelerate faster. The effect is similar to fitting a lightened flywheel and is particularly noticeable in the lower RPM range before the turbo spools up. This is because the power required to accelerate a heavy pulley accounts for a much greater proportion of the available power at low RPM.

Go Fast Bits Atomic Boost Controller: Ford; Holden; Mazda; Mitsubishi; Nissan; Subaru; Toyota
Part #: 3001

Product Details: GFB puts the key to boost control in YOUR hands!

All turbocharged vehicles utilize some form of factory boost control, most of which display a tendency to be conservative in allowing the boost to build up, and then taper away noticeably toward redline. A GFB Boost Controller however, not only allows quick and easy boost level adjustment, but it can also reduce the boost threshold (the RPM at which boost starts to rise) and maintain a rock-steady upper limit.

Fits:

Ford Laser TX3 Turbo 4WD KE - KHII (1987 – 1993)
-The TX3, like many turbo cars, is limited in the boost that it can safely use by the efficiency of its intercooler and turbo compressor and the capability of its fuel supply system. Boost can be increased to the limit of the turbo's efficiency, for a good power increase, provided that intake air temperatures are kept close to ambient and enough fuel is available. Boost increases should always be made carefully, with the aid of an accurate boost gauge.

Ford Telstar TX5 Turbo AS - AV (1986 – 1991)
-
The TX5, like many turbo cars, is limited in the boost that it can safely use by the efficiency of its intercooler and turbo compressor and the capability of its fuel supply system. Boost can be increased to the limit of the turbo's efficiency, for a good power increase, provided that intake air temperatures are kept close to ambient and enough fuel is available. For smaller turbos, like the one used on the TX5, better results are often had by increasing boost just a couple of psi, rather than pushing it too high and taking the turbo out of its efficency range.

Holden VL Commodore Turbo (1986 - 1988)
-The VL Turbo uses a screw-in factory pop-off valve on the inlet manifold, which is nothing more than a spring-loaded overboost protection device. Typically these leak significantly, and should definitely be removed and plugged if you intend to raise the boost level.

Mazda 626 and MX-6 Turbo (1986 - 1991)
-The Mazda 626 and MX-6, like many turbo cars, are limited in the boost that they can safely use by the efficiency of their intercoolers and turbo compressors and the capability of their fuel supply system. Boost can be increased to the limit of the turbo's efficiency, for a good power increase, provided that intake air temperatures are kept close to ambient and enough fuel is available. For smaller turbos, like the one used on the 626 and MX-6, better results are often had by increasing boost just a couple of psi, rather than pushing it too high and taking the turbo out of its efficiency range.

Mazda RX-7 S4 & 5 (1986 – 1991)
-The main factor limiting the maximum safe boost level of a 13B turbo are the standard 2 mm three-piece apex seals. Factory boost is 6.2 psi for a series 4 RX-7, and 8.2 psi for a series 5. The reliable limit of these engines is 10 - 12 psi. If the engine is rebuilt and fitted with more durable 3 mm two-piece apex seals, then the engine will safely handle a higher boost level, although at above 14 - 15 psi, the factory turbo becomes inefficient and those seeking more power should install a high flow or larger aftermarket turbo.

Mitsubishi Starion Turbo JA - JD (1982 - 1987)
-GFB recommend that an intercooler is fitted to JA - JB Starions before attempting significant boost increases. Without one, the boost could probably be increased 1 or 2 psi fairly safely, but adding an octane booster to each tank of fuel would be a good measure against engine damaging detonation. Intercooled JD Starions could probably tolerate 2 or 3 extra psi using high octane (98 RON) unleaded fuel.

Mitsubishi Cordia GSR Turbo AA - AC (1984 – 89)

Mitsubishi CC Lancer GSR (1992 - 1996)

Mitsubishi Lancer EVO

Mitsubishi Galant VR-4 (1990 - 1993)

Nissan 200SX SR20DET S14 – 15 (1994 – 2003)
-The 200SX typically responds well to a modest boost increase, but the small factory intercooler poses the first restriction in the quest for power, being unable to scrub sufficient heat from the intake charge to ward off detonation at higher boost levels.

Nissan S13 Silvia & 180SX CA18DET

Nissan S13 Silvia & 180SX SR20DET

Nissan Skyline GTS-t R32
-Skylines typically respond well to a modest boost increase, but the small factory intercooler poses the first restriction in the quest for power, being unable to scrub sufficient heat from the intake charge to ward off detonation at higher boost levels.

Subaru WRX MY94-96
-The factory ECU cuts fuel if it senses boost exceeding 16-16.5psi (1.08-1.12 bar) for more than about half a second. It is common for these cars to easily handle boost increases up to this level. Beyond this, the fuel cut can be lifted or removed, but the small factory intercooler will limit the amount of boost you can run through it.

MY97-98 WRX and Version 3-4 STi
-On the WRX model the factory ECU cuts fuel if it senses boost exceeding 16-16.5psi (1.08-1.12 bar) for more than about half a second. It is common for these cars to easily handle boost increases up to this level. Beyond this, the fuel cut can be lifted or removed, but the smaller factory turbo will start to run out of puff beyond 15psi, particularly at high RPM. It is common to see these models drop back to about 12-13psi by redline, even if peak boost is set above 16psi.

MY99-00 WRX and Version 5-6 STi
-On the WRX model the factory ECU cuts fuel if it senses boost exceeding 16-16.5psi (1.08-1.12 bar) for more than about half a second. It is common for these cars to easily handle boost increases up to this level. Beyond this, the fuel cut can be lifted or removed, but the smaller factory turbo will start to run out of puff beyond 15psi, particularly at high RPM. It is common to see these models drop back to about 12-13psi by redline, even if peak boost is set above 16psi.

MY01-02 (MY02-03 in the U.S.) WRX and STi ("bugeye")
-On the WRX the factory ECU cuts fuel if it senses boost exceeding 18psi (1.22 bar) for more than about half a second. Boost can be quite safely increased by a modest margin, and this model shows the biggest improvements, thanks to a lethargic factory boost curve. Very good low and midrange gains can be had by the installation of a boost controller.
-The smaller factory turbo will start to run out of puff beyond 16psi, particularly at high RPM. It is common to see these models drop back to about 12-13psi by redline, even if peak boost is set above 16psi.
-A word of warning on this model, there is a catalytic converter placed before the turbo in the up-pipe, and it has been known to fail with increased power levels (Subaru deleted this cat on the MY03 model). There is also an exhaust sensor in the same position, which can sometimes trigger the check engine light with increased power levels. There are a number of companies making replacement cat-less up-pipes for these models, which is worth looking into if you plan to modify your car significantly.

MY03-current (MY04-current in the U.S.) WRX and STi
-On the WRX model the factory ECU cuts fuel if it senses boost exceeding 18psi (1.22 bar) for more than about half a second. Boost can be quite safely increased by a modest margin, but keep in mind with the higher compression ratio of this model, large increases should not be made without proper modifications. This model uses a smaller capacity fuel pump and injectors than previous models, so the safety headroom is reduced.

Go Fast Bits Black Crank Pulley Non-Underdrive: Subaru
Part #: 2009

Product Details: Install a GFB light-weight under-drive pulley kit and get better throttle response and more power!

How do they do this?

1. Less weight - GFB's pulleys are manufactured on the latest Multi-Axis CNC machines from the highest grade 6061-T6 aluminium billet, making them immensely lighter than their factory steel counterparts. This lower weight yields a large reuction in the rotating inertia of the belt train, allowing the engine to accelerate faster. The effect is similar to fitting a lightened flywheel and is particularly noticeable in the lower RPM range before the turbo spools up. This is because the power required to accelerate a heavy pulley accounts for a much greater proportion of the available power at low RPM.
2. Under-driving - Additional power increases also come from making the crank pulley smaller, thereby slowing down the accessories and reducing the driven load (particularly at high RPM), without affecting their operation.
