Models now covered with supercharger kits
GC8 98 - 99 - MAP sensed 3 plug ECU 2.0 , 2.2 and 2.5 (AUS, USA. UK)
GDA - 00 - 04 MAP sensed 3 plug ECU 2.0 and 2.5 liter (AUS,USA,UK)
GDB - 04 - 05 MAP sensed 3 Plug ECU 2.0 and 2.5 liter (AUS,USA,UK5)
GG + 08 - 11 MAF sensed 2.5i (USA/CANADA)
Legacy/Liberty 2.5 MAP sensed 3 plug ECU 1999
The thread is named Subaru GDB (should also have GDA) supercharger kits - thats exactly what it covers. Yes these models are in the USA and do have the following features. If your Subaru doesn't align with info provided so far then it soon will, just as soon as the development machine gets to it
If you have a Subaru with the following features our current kit will bolt to it:
1. The machined step on the right hand side manifold
2. Flexible high pressure hose from P/S pump and remote P/S fluid reservior
3. GDA and GDB body style
If you have a 98 - 05 Subaru with the following features our current kit and piggyback ECU will fit to it:
1. The machined step on the right hand side manifold
2. Flexible high pressure hose from P/S pump and remote P/S fluid reservior
3. GDA and GDB body style
4. 3 Plug ECU
5. MAP sensed
3 levels
1. Not intercooled 6.0 psi boost USD 2800.00) + freight
2. Intercooled 6.0psi
3. Intercooled 8.0psi
If you have a 05 - 11 Subaru with the following features our current kit will fit
1. 2.5i engine
2. MAF sensed
New USA kit price - NON INTERCOOLED
The pricing is same for all Impreza and Legacy kits from 2001 model - 2011 model cars with EJ engines with alloy intake manifolds. THIS EXCLUDES 2004 MODELS OF IMPREZA WITH PLASTIC INTAKE MANIFOLD.
You get a complete non intercooled 6-7psi supercharger kit - to make your car work properly you will need to ADD WRX injectors and a TUNE
AUD$2750 + Postage (typically AUD$245) +3% extra if paid through PAYPAL (thats what they will slug us)
I have listed it in AUD so we can deliver without being killed by currency exchange rates.
Now more affordable than ever due to increased interest from your part of the world
PS* These kits will make your RS really perform, way easier than a motor transplant, it will be setup to give your RS the max safe power it can take with out being unreliable. Not more and not less.
PPS* Do not post in this thread asking for 10 - 20psi or wanting the kit for turbo short blocks etc, you are welcome to buy our excellent engine management system to make your tuning task easier but otherwise suggest you go the whole turbo engine as a swap if you want the BIG psi
ADDITIONAL INFO POSTED 2/10/2012
Boost is 6.0psi, very progressive and working well with the 10.1:1 compression.
The injectors have a LOT of range left to go yet, so the entire fuel system is handling this like easy for the AU,NZ and SA Subarus. USA/CAN NA Subaru's all need larger than stock injectors - Fuel pumps on all models worldwide are fine for 6psi
The torque is very unusual but the dip at the start still results in higher than stock torque and then increases MASSIVELY.
The stock power was 95kw and 240Nm (disregard the silly bit at start of the run) at the wheels which was very good due to breathing directly into throttle body, no alternator and P/S belt and the very good exhaust system.
The next chart should show the best run, well it was the best final tuned run as the best run was 123kw at the wheels but just too hot later into test to make that number again. So 119kw and 351Nm was measured. Increases of 24kw and 130Nm, that torque is unreal and when you change gear the car cranks right back into it.
The final chart shows the difference between stock and Supercharged at 6.0psi.
So as you can all clearly see there is enormous potential left in this system with the blower easily able to make 5psi more and some intercooling benefit, this could see the torque go another 80 or more if we go all the way.
Taking the pod filter off makes another 3-4 kw or brings boost up another .4psi.
To sum it up, its 40Nm ahead of but same engine kw (160kw) as the MY05 WRX 2.0 as delivered to Australia. NICE but with out the dead bottom end power of the WRX. Those in Canada or Nth America's colder area's could expect better numbers too. We are not exactly creating WRX killing weapons here, just increasing your NA power as reliably as possible.
In the last image is you will see data that is beginning to back up the dyno results! From the Dynolicious App on IPHONE. THIS IS FROM A SINGLE RUN, I didn't do any before or after, was just going for one perfect (as possible) run, could have revved it more in 3rd gear before changing but otherwise not bad.
Some of the data behind that chart is as follows:
Temp at time: 29C/84F
0 - 60kmh - 3.0 secs
0 - 100kmh - 6.4secs (62.1mph)
Quartermile time: 14.36 @ 162.1 kmh (100.6mph)
Max acceleration: .83G's
Peak Power 162kw (BINGO )

Cars are running super reliably with this kit across all variants - 05 - 11 2.5i models can all be supercharged with the Raptor kit
GC8 - MAP sensed 3 plug ECU 2.0 liter & Phase 2 SOHC 2.2L (AUS, UK, not sure if this model was in USA)
The GC8 kit has all the same features as above GDA/B kit, refer there for additonal detail

Waiting on GC8 MAF sensed 2.0 and 2.5 (USA) only needing ECU pin out data
Waiting on GDB 4 plug ECU 2.0 (AUS, UK, USA)
GOING 9 PSI or more
I think before long we will all want to run a touch more boost, to do that safely consider that you WILL NEED EVERY item from the following list to have RELIABILITY
1. 380cc Deutschworks injectors or equivalent WRX injectors
2. Water to air or Air to Air intercooler system
3. High flow fuel pump (in tank)
4. 32mm BOV with 2Kg spring
5. Knock sensor with LED display using a Subaru knock sensor where possible.
If you aren't prepared to do the things in the above list ^^^^^ don't bother even contemplating the higher boost, we want you to have reliability not another broken engine story.
Unless your Subaru has a busted clutch or dodgy automatic this next step would should put every 2.5 Impreza at around a mid 13 quartermile as its quite a big step up from the 14.1. I ran with 5psi
