Models now covered with supercharger kits

GDA - MAP sensed 3 plug ECU 2.0 and 2.5 liter (AUS,USA,UK)
GDB - MAP sensed 3 Plug ECU 2.0 and 2.5 liter (AUS,USA,UK)

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 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 - final specification will depend on what I discover along the way. ALL PRICES PLUS FREIGHT

1. Not intercooled 5.2 psi boost AUD$4400 (USD 2500.00) based on .64cent AUD and AUD local tax removed
2. Intercooled 5.2psi
3. Intercooled 6.2psi


This kit will transfer across several models of Subaru so essentially what is seen here is a snap shot of a bigger scene.


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 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 14/12/2008

I have decided pretty much that this will be the Stage 1 system for now, in bad weather (HOT AND HUMID) conditions its still a safe kit when not intercooled. The torque increase should be taken notice off as there is a lot of cylinder pressure making that happen even if boost appears low so it will pay to not ask for too much more without intercooling, this would be a mistake many have made in the past - going hard because it all seems to be going too easy.

Boost is 5.2psi, 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.

I didn't measure the boost temps but even well into the session I was able to hold my hand on the charge pipe for greater than 15 seconds, so I would suggest around 50-55 celcius which is excellent for non intercooled.

The torque is very unusual but the big 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 5.2psi.

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 )







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)

Do you have any bigger dyno charts?
351Nm is about 260 lb-ft of torque... is that at the wheels? I made that at 14 psi of boost....hmmmm... interesting.

[dubkeith]

That is a rediculous amount of torque. Hign compression Supercharged motors do make big torque numbers, but usually at much higher RPM's than a turbo car. You probably made that 260ft/lbs at like 3000 rpm though right?

Any Canadian kits being shipped soon Tim???

[IneedIspeed]

Lil expensive though eh? I mean 5k will get you an entire swap. =/

[GREENEJ25]

$2500.00 for 5.2 psi non intercooled system which nets you 165hp at the wheels isnt too bad! Thats slightly better than a WRX.

[Battlesnake99]

So Youre recommending 98 octane?? Would 93 be ok here in the states?

On their site it says 4400 for that. =/

^^^Thats Australian Dollars! If you search thru the original thread Tradewind converts it to US dollars for everyone!

Thats the baseline kit....then there is the intercooled kit which yeilds even more Torque for another grand!
