The Liberty Files

For Years now we at S & J have prided ourselves on our ability to tune not only the "Rebel Racers", but also the Prestige Luxury machines that Subaru have so lovingly put together for us!

Once again we are backed up by the perfect combination of EcuTek and MRT Performance, who are both consistently at the forefront of development when it comes to packaging upgrade kits for each model as it emerges.

Liberty B4 Twin Turbo

A rare beauty, but not without its flaws, the only two complaints we here about this model in standard trim are:

  • Engine "pinging" (detonation) under load.
  • The VOD (valley of death), which is the woeful dip in power during the transition from boost in the first turbo to both (3,500- 4,500 rpm).

These two problems are rectified with an EcuTek type 2 re-map, not to mention the 30 kw extra all for $1775 including 4wd dyno tuning. From there as with it's single turbo cousins, the B4 responds very well to exhaust, fuel pump and intercooler upgrades, as you can see on this dyno graph.

Liberty GT MY04-MY06

Even more refinement in regards to luxury, but now sporting the much talked about twin scroll turbo plus plastic intake plenum, electronic throttle and AVCS (active valve control system) on all 4 camshafts. This car is a real pleasure to tune, with such technology in electronics and engine hardware, incremental increases in boost combined with AVCS, fuel and ignition timing changes allow 30 kw extra, with improvements in fuel economy all part of the first upgrade package at $1775 including 4wd dyno tuning. Note that STI models respond just as well to these upgrades in both manual and Tip-tronic versions! 

Liberty GT and GT spec B MY07-MY09 (incl. STI)

Here we have the much awaited and anticipated 2.5L version of the beautiful Liberty GT. The lack of extra kw from the 2.0L predecessor is made up for by torque, and in our case leaves un-tapped power. The all new "SI Drive" feature gives us some more power as tuners, the power to give the driver genuine "map switching" with distinct power and torque differences between the Sport & Sport Sharp modes. From factory Subaru have done a beautiful job of "sharpening" up the faster mode, but as you will see in the dyno graphs there is a very minimal kilowatt difference between the two at full throttle. A full EcuTek type 4 retune costs $1990 including 4wd dyno tuning and nets 20 kw on Sport with a 30 kw gain on Sport Sharp. As always fuel economy is a focus for us, and as a result we have seen as much as a 1.2L/100km improvement. Once again Tip-tronic and STI versions are no trouble at all.



 

Liberty GT MY10-MY14 

New Lines, more room, even more comfort, are all great features, but what’s real exciting for us are the elaborate changes to Turbocharger in regards to size, type and positioning. The New Twin Scroll VF54 turbo has been responsible for an extra 20+kw ATW over the MY09 GT, and has given us (the EcuTek/MRT Team) even more scope, in regards to power and torque throughout the entire RPM range. See the dyno graph below for improvements at the XA kit Level only (no Hardware changes at all). Still featuring the "SI Drive”, EcuTek tuners have the power to give the driver genuine "map switching" with distinct power and torque differences between the “I”, “Sport” & “Sport Sharp” modes. From factory Subaru have done a beautiful job of "sharpening" up the faster mode, but there is a very minimal kilowatt difference between the three modes at full throttle. A Full EcuTek type 4 retune costs $1990 including 4wd dyno tuning and nets over 15 kw in Sport mode with a 20 kw gain on Sport Sharp. As always fuel economy is a focus for us, and as a result we have seen as much as a 1.2L/100km improvement. Once again Tip-tronic versions are no trouble at all.  

Liberty 3.0 R spec B

Public demand has encouraged us to give this beautifully appointed non-turbo 6 cylinder a tune-up.

The three main complaints from owners of these prestigious sports cars are:

  • Throttle hanging on after lift off.
  • Surge at full throttle.
  • RPM limiter is too violent.

 The issues above are easily rectified with an EcuTek Factory ECU re-map, an extra 15kw through the mid range plus 10 in the top end are also appreciated by any enthusiast! Cost for all of this is $1775 for the MY05-06 and $1990 for the "SI Drive" MY07-09 models including 4wd dyno tuning, and before and after printouts. Exhaust systems range from $1350 for a pair of S/S MRT rear mufflers, up to $2950 for a complete system including custom made headers.

We can tune your whole car!

Remember tuning a car to your needs doesn't necessarily stop at the engine and computer, brake and suspension upgrades can significantly improve your car too! With MRT and Whiteline constantly developing upgrade kits for all levels of touring and driving, we can tailor a package to satisfy your requirements!
