GFB - Respons TMS BOV + Short Shift Kit + Pulley Package - (WRX/STi 99-00)

GFB Respons 

The TMS range from GFB is designed specifically for the purpose of turbo lag reduction and improving throttle response. Tests show TMS features can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

Want sound? Admit it, you do - otherwise you wouldn t be looking at this product! Even if you only want to hear it a little bit, only some of the time, or hide it from your better half, GFB's unique patented venting bias adjustment system has you covered - it allows the amount of air vented to atmosphere or recirc to be infinitely varied to change the sound from silent to ear-shattering or anywhere in between, with a simple flick of the wrist!
 

• Unique adjustment to easily change distribution of vented air between recirculating and atmosphere ports.
• Great for cars with sensitive air flow meters as it can be tuned to vent just enough air back to the inlet to prevent backfiring, whilst achieving a blow-off sound.
• Direct bolt-on fitment NO extra parts, adaptors, or modifications to the car required just take the factory valve off, and put the GFB Respons TMS in its place!
• Excellent value!

These unique products manufactured in Australia to ISO 9001 can deliver performance with as much or as little noise as you like; with the GFB Respons TMS 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 atmosphere-venting valves on cars with MAF sensors.


NOTE : Used with STD Intercooler, Please check fitment if using a after market intercooler

GFB Short Shift Kit

GFB's Short Shift kits are like no other. Until you feel the action of one for yourself, you won t believe the difference!

Why did we bother to make a short shift kit, when there are so many other brands available? Because there was room for improvement!

Our unique system means that not only is the shift throw distance fully adjustable, it can be reduced more than any other brand by a long shot (at the shortest setting, the throw from 3rd to 4th is a mere 55mm, or 2.15 ), whilst retaining the stock gearstick height.If you want a race-car feel when you change gears, look no further than a GFB short shift kit, the shortest throw shifter on the market!

Light Weight Pulley Kit

GFB lightweight underdrive pulley kit is made from anodized aircraft-grade billet 6061-T6 aluminium and offers sharper throttle response and faster acceleration. Kit includes: crank, alternator and power steering pulleys, and 2 belts. GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev. 

We know that people are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured we have done our homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories, and whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, we steer clear of those. The kits we release are thoroughly application tested and do NOT cause engine damage in the short or long term.
