An affordable Oil Cooler done the right way!

While track-side tuning Brian Locke’s WRX US Touring Car, the WRX’s ability to sufficiently cool its oil when operating in extreme conditions became glaringly apparent. Even in cool weather with moderate cycling, the factory system seems stressed, resulting in dangerously high oil temperatures (this is probably why the Spec C’s come with an oil cooler from the factory). After testing various solutions, we finally selected a setup that is more than capable of dealing with the stress of road racing.

With the Gruppe-S Oil Cooler, the racing oil temperature was reduced a consistent 40 degrees F, even in 110 degree + temperatures of Arizona, as proven with our data logs. In short, this oil-cooler works and it has been track tested on a race winning vehicle.

Key Features:

*High quality European core (240mm x 120mm x 45mm), not some Taiwanese knock off core.
*Thermostat operated Oil Cooler to avoid cooling cold oil upon startup.
*Aerospace fittings / stainless steel lines, professionally assembled and tested to 1000psi.
*Light weight mounting brackets.

In the words of Brian Lock, “this oil cooler rocks. After installing this setup we never had a problem with oil temperature again. Even at PIR where it was 115 and it was so hot inside the car I thought my legs were on fire, it was golden. Brian Lock thinks that this oil cooler is the *****, Brian Lock thinks you should buy it.”

Apex'i Induction Box - 02+ WRX / 04+ STi - JDM Spec - $150 Shipped!!
By fully enclosing the filter element and directing the intake air away from the heat soaked engine components, the APEXI WRX induction box helps prevent the ingestion of hot, preheated air from within the engine compartment. This reduction of intake air temperature promotes more efficient combustion, which in turn creates better performance and increased reliability. The box does not include a new filter.


Greddy Air Inx Intake Kit - 02+ WRX / 04+ STi - JDM Spec - $120 Shipped!!
The Greddy Air Inx intake features a dual element foam filter which is more adept at filtering than your stock filter. It also allows for increased air flow which, when coupled with increased fuel, results in increased power.


Accessories:

Cusco Aluminum Radiator Shroud (blue) - 02+ WRX / 04+ STI
Approximately 20% of incoming air current is diverted away from the radiator by the radiator support. The radiator shroud reduces this loss, by redirecting airflow over the radiator. The result is an increased cooling efficiency of the radiator.
$99 Shipped!!!


Gruppe-S Heat Shield- 02-05 WRX
This heatshield will lower your underhood operating temperatures by directing heat from the turbo and downpipe away fromt your TMIC and the rest of your engine. This will in turn lead to more power from cooler intake temperature and better engine operating conditions.
$49 Shipped!!!

Gruppe-S V2 4-1 Manifold with Jet Hot 2000 - $575 shipped !
The Gruppe-S manifold is a 4 to 1 manifold designed to provide extensive midrange and top-end power gains. Our manifold features T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. The 4-1 collector is cast to ensure the smoothest possible low rates. Strong gains in both HP and torque can be expected with the addition of the manifold, especially with high horsepower applications. The Jet Hot 2000 outside coating eliminates heat loss thus virtually eliminating low end power loss (compared to stock headers). These are the best coated headers we have ever seen; the coating is evenly applied with no bubbles and is absent from all bungs and threading. Includes all necessary gaskets.




Gruppe-S V2 Manifold - 02+ WRX / 04+ STI - $399 Shipped!


**Dyno graphs shows testing with 04 WRX catted downpipe, uppipe, exhaust, versus addition of manifold only.

Right now for a limited time only, if you provide us with your 2.5L block, get a $500 discount on any of our staged motors!!!

STi 2.5L Shortblock now obsolete? Gruppe-S Staged Motor Packages!

Why pay $1600 for an STI shortblock just to throw in $500 forged pistons, then pay $200 for installation ($2300) when for $299 more you can purchase a Gruppe-S Stage One Shortblock ($2599)?

So you're probably wondering, what exactly do I get for that extra $299?

Well, you also get:

-Race Spec Coated Bearings
-Complete balance of rotating assembly to within 1 gram
-Professional Assembly

Press Release:

Gruppe-S is proud to announce that it now offers complete built motor packages to the general public. A service only available to local customers previously, we have combined the best and most cost effective components available to form staged motor packages that should suit nearly every Suby junkie’s needs. These short and long blocks will support anywhere from 535 CHP to 700 CHP and all provide increased strength, power, and reliability. They are sold as packages so that you, the user, doesn’t have to worry about any options, specifics, or details.

---------------------------------------
Stage 1:

Not so crazy that it can’t be driven on the street but strong enough to handle almost anything that can be throw at it, the Gruppe-S 2.5 Stage One Motors are designed to reduce the compromise between high horsepower and reliability. Available as either a short block or long block that utilizes either your USDM STi’s AVCS heads or WRX EJ20 heads off of your own motor (includes custom gaskets for proper compression ratios), this motor is essentially a beefed up version of the USDM STi motor. Derived from our extensive experience building and tuning both race and street cars, our Stage 1 eliminates the failure points of the stock STI engine. We have replaced the stock hyper-cast pistons with our custom forged units by Wiseco. Wiseco Pistons were selected due to their versatility for both street and race applications; they eliminate the compromise of a "loose" race piston by retaining a better operating range. The factory bearings have also been replaced with coated race units that eliminate the spun / seized bearing issue we often see in high power applications. The longblock utilizes Cometic gaskets and ARP Head Studs to affix the heads to the block. Finally, the entire assembly is professionally balanced and assembled to race specifications (within 1 gram). When coupled with the lighter forged pistons, the is a redline that has been raised to 7500RPM. We recommend this short-block for all Subaru owners making in excess of 460HP. Can the stock motor hold more power? Yes, but based on our experience building and tuning literally hundreds of Subarus, the reliability of the engine becomes questionable at those power levels.

Assembly time is generally 3-4 weeks. For the Long block option, we require a core charge for the heads which will be refunded if you heads are in good working order.

Features:

-Gruppe-S / Wiseco Forged Pistons
-Gruppe-S Coated High Performance Rod & Crankshaft bearings
-ARP Headstuds (on long-block option)
-Cometic Head Gaskets (on long-block option)
-Professionally balanced rotating assembly (recommended 7500 RPM redline)
-Rehoned cylinder walls
-Capable of up to 535HP Operation
-Final Displacement 2.48L
-Compression ~8.5 : 1

$2599 for short-block
$3099 for long-block (+$1500 core charge)

---------------------------------------
Stage 2:

The Gruppe-S Stage Two Race Engine is a logical progression from Stage One: it combines our Stage One short block with a treated / reworked crankshaft for high RPM operation. The combination of forged pistons, coated race bearings, proper balancing, and re-worked crankshaft yields a potent short-block capable of supporting a staggering 600HP while also revving to 8000RPM. On the longblock option, Gruppe-S Stage Two camshafts (AVCS on STI), an upgraded valvetrain, and titanium retainers are added for extra breathing ability.

Assembly time is generally 3-4 weeks. For the Long block option, we require a core charge for the heads which will be refunded if you heads are in good working order.

Features:

-Gruppe-S / Wiseco Forged Pistons
-Coated High Performance Rod & Crankshaft bearings
-Reworked high RPM crankshaft
-Gruppe-S Stage Two camshafts (AVCS available) (on long-block option)
-Gruppe-S Stage Two Valve Train (on long-block option)
-ARP Headstuds (on long-block option)
-Cometic Head Gaskets (on long-block option)
-Professionally balanced and assembled (recommended 8000 RPM redline)
-Rehoned cylinder walls
-Capable of up to 600HP Operation
-Final Displacement 2.48L
-Compression ~8.5 : 1

$3299 for short-block
$5499 for long-block (+$1500 core charge)
