Hey guys,

We have a lot of new awesome products coming in soon. We're now taking pre-orders on them. Check them out:

Helix V3 Uppipe for 02+ WRX / STI - $TBD - ETA: LATE JULY

The new Helix V3 Uppipe is designed primarily for use on the newer 2.5L Subaru turbocharged motors. It features a larger 2.3” diameter and external port for a 38-42mm external wastegate. The larger 2.3 diameter piping is well suited for big-power blot-on turbos (such as the Helix RR500 turbo) because it allows for greater exhaust gas velocity at the turbine nozzle. Utilizing an external wastegate allows for improved boost stability that can result in additional power. The V3 Uppipe is designed to be used in conjunction with the Helix V3 Downpipe, which features a return port for external wastegates. The uppipe features SS304 stainless tubing, SS304 flanges, and TIG welding. for an external wastegate.



Helix V3 Downpipe for 02+ WRX / STI - $199 shipped - ETA: LATE JULY

The Helix V3 downpipe incorporates all the popular features of the V2 downpipe with the addition of an external wastegate provision. This provision allows for external wastegate gases to be vented back into the downpipe. Helix also re-designed the bellmouth to reduce production costs without sacrificing the SS304 mandrel tubing, high quality TIG welding, etc. The end result is a better downpipe at a lower price.



Helix Catted Downpipes for 02+ WRX / STI - $399 shipped - ETA: LATE JULY

The Helix Catted Downpipe incorporates Helix Power’s first-rate bell-mouth downpipe, with the addition of a 200 cell Metal-Substrate high-flow catalytic converter and thermal barrier heat-shield. The 200 cell Metal-Substrate downpipe has been tested by us to yield 7-10whp over the factory twin cats, while able to pass stringent California smog standards on the WRX / STI. The thermal barrier heat-shield assists in rapid warm-up of the cat for maximum efficiency and helping to reduce engine bay temperatures.

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



GFB Lightweight Pulley Kit - 02-05 WRX

SMC Alcohol / Methanol Injection Packages

Designed to be a hassle free upgrade, this package includes everything you need to get alcohol injection running properly on your car. Although many people are “scared” of alcohol injection, if utilized properly, it is perfectly safe while also being one of the best bang for the buck power adders available for a boosted car. Alcohol injection works by injecting a fine mist of alcohol into the intake stream. This does two important things:

1) Alcohol Injection lowers the temperature of the intake charge to create a denser (and thus greater) air mass.

2) Alcohol Injection raises the effective octane of your fuel which works towards avoiding detonation (the sworn enemy of engines).

These two factors are particularly beneficial on turbocharged cars because the effectiveness of turbocharging is dependent on having a dense and cool intake charge while also avoiding detonation. Boosted engines are particularly succeptable to detonation because they can see such high pressures and temperatures. By increasing the effective octane of your fuel, it allows you to run higher boost and add more timing advance. It is not uncommon to see HP gains as high as 20-30% with these changes, regardless of modifications. Additionally, two added bonuses of alky injection are that it also cleans your engine and will work with pump gas.

The SMC Alcohol Injection System is unique, reliable, and safe in several regards. Designed from the ground up specifically for the Subaru WRX and STi, this system includes a 1 gallon washer fluid tank that serves as a reservoir. This makes for a very simple and stealthy install. A small auxilliary washer tank/pump that mounts in front of the battery is also included so that you can still clean your windshield. Another unique feature of this kit is the Progressive Controller. An extremely small unit that can be fitted nearly anywhere (it measures only 2.75" wide x .9" high x 4.6" deep), this microprocessor based device will automatically increase alcohol spray pressure as boost rises. This system runs on denatured alcohol that can be bought nearly anywhere.

As is wise when running high boost levels, tools critical to tuning are highly recommened to be used in conjunction with this kit. A wide-band 02 controller, knock link, and tuning are suggested.

- Increase effective octane of fuel
- Drastically decrease temperature of intake charge
- Allows higher boost and more timing advance
- Expect 20-30% HP increases
- Stealth installation

SMC Alcohol Injection - $499 Shipped!

We are offering the following packages:

SMC Alcohol Injection + Link Knock Link + PLX M300 Wideband - $1099 Shipped!

This combo includes everything you will will need (short of EM) to tune and safely run alky injection on your car.

Gruppe-S Oil Cooler Kit - $479 Shipped!

This Oil Cooler kit was introduced to the public after testing several iterations on Brian Lock's USTCC race car in the deserts of Arizona. The stock WRX and STi lack an oil cooler and running any turbo charged motor hard puts an extreme load on the motor's cooling systems and fluids. Keeping your oil cool not only prolongs the life of your oil but more importantly, it prolongs the life of your motor. This is one of the most overlooked upgrades on the WRX / STi and we feel that anyone who drives their turbocharged vehicle hard should have one. Perhaps that's why the Spec. C comes with an oil cooler from the factory. This oil cooler is track tested on a race winning vehicle and data logs show that it works. In comparison to competitors' oil coolers, the Gruppe-S Oil Cooler features an extremely high quality European core manufactured by a world famous brand and a thermostat of similar quality.

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 USTCC race car driver 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.”



Gruppe-S Forged Connecting Rods for EJ25T (STI, LGT, FXT) - $399 shipped!!!

These are super high quality forged steel connecting rods made by a famous JDM aftermarket manufacturer (please e-mail for this info). They will fit in any 2.0L WRX / STi or 2.5L STI / FXT / LGT motor. These would be an excellent rod choice for anyone building a 2.0L or 2.5L motor and should support well over 600 WHP. These rods feature ARP L19 rod bolts which are widely considered to be the best on the market.
-Very high quality forged steel connecting rods
-Manufactured by a world renowned JDM company - PM FOR MORE INFO
-Use ARP L19 con rod bolts (regarded as the best on the market)

Built Shortblocks and Motors:

Built Ver. 8 JDM STi Shortblock - $2999 + Shipping

We have one rebuilt Ver. 8 JDM STi shortblock that's priced to move. This is without a doubt the ultimate JDM STi motor to have; it revs to 8K and should hold close 30 PSI reliably. It includes:

-Gruppe-S / Wiseco Forged and Coated Pistons
-Coated High Performance Rod & Crankshaft bearings
-Forged and nitrided STi Crankshaft
-Helix Forged H-beam Connecting Rods w/ ARP L19 bolts
-Professionally balanced and assembled
-Rehoned cylinder walls

Bolt on some good heads and this motor should be an absolute monster capable of holding 600+ CHP.

Gruppe-S 2.2L Stroker Kit for EJ20T - $1399 + Shipped

These are all the parts needed to build a 2.0L turbocharged motor (WRX or JDM STi) into a serious power making 2.2L stroker motor. This motor should be capable of holding 550 crank HP while revving to 7500 RPM if properly balanced. It includes the following:

-Custom spec Wiseco forged stroker pistons
-STi forged connecting rods and bolts
-STi forged crank shaft
-Gruppe-S coated racing bearings

Gruppe-S 2.5L Stage 1 Shortblock - $2599 + shipping

Our Stage 1 shortblock replaces the components we feel are most likely to fail in the USDM STi shortblock. This is essentially a bulletproof USDM STi shortblock and will compliment a GT30R, SZ55, FP Red , FP Green, or TD06-20G sized turbo nicely on 100 octane. WRX owners can benefit from this shortblock also since their heads will bolt right onto it; however, combining their heads with something like the Helix cams and valvetrain and this shortblock would yield something with peak power output similar to the USDM STi. In comparison to other companies' Stage 1 shortblocks, our adds coated race bearings and balancing to within 1 gram (JDM STi motors are balanced to within 7 grams).

Features:

-Gruppe-S / Wiseco Forged Pistons
-Gruppe-S Coated High Performance Rod & Crankshaft bearings
-STi Forged Connecting Rods
-STi Forged Crankshaft
-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 535+ CHP Operation
-Final Displacement 2.48L
-Compression ~8.5 : 1

*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.

Gruppe-S 2.5L Stage 2 Shortblock - $3599 + Shipping

We are pleased to announce the release of our second generation Stage 2 2.5L Short Block. The GS650 exemplifies all of our experience building and tuning high horsepower race and street engines. The GS650 has been installed on daily-driven cars that make over 600HP on the street, safely and reliably. These are the same cars that drive to the track, run sub-11 second times and are driven home. This block is capable of maxing out the GT35R turbo (ask MARKGSTI ).

The GS650 starts life as a regular STI shortblock. First we replace the weak hyper-cast stock pistons with custom spec forged units (coated). Not only are the pistons significantly stronger than the stock units the pistons are substantially lighter too. We then address the connecting rods. The rods are replaced with Helix forged H-beam rods held together with ARP L-19 bolts. The super-strong forged rods coupled with the best rod bolts available on the market allow for high RPM operation. The crankshaft is then modified with our proprietary techniques creating a crankshaft similar to the $2000 STI race crankshaft used on the WRC cars. The bearings are swapped out in favor of Gruppe-S coated race bearings. This addresses all the common main failure points of the stock STI 2.5 engine – spun bearings, cracked pistons, and damaged rods.

The entire assembly is then balanced. Piston walls are bored and honed, all tolerances are triple checked, and the assembly is professionally assembled. The end result is a big power engine that is capable of 8500 RPM operation* and holding 650 crank HP. That’s right, 165 HP PER A CYLINDER. The GS650 is purposely built to tight tolerances for street operation. You will not experience excessive oil consumption and you will not have a rocking issue with our pistons.

Recommended Limits:

-7500RPM redline**
-30psi boost limit
-650HP reliable horsepower limit

*”Looser” race engines (not recommended for street use) are available – simply let us know if that is what you are looking for.

**8500 RPM requires substantial modifications to the head, oiling system, and other components. We have experience building high revving engines, please contact us for additional details.



Features:

-Gruppe-S / Wiseco Forged and Coated Pistons
-Coated High Performance Rod & Crankshaft bearings
-Reworked Forged STi Crankshaft
-Helix Forged H-beam Connecting Rods w/ ARP L19 bolts
-Professionally balanced and assembled (recommended 7500 RPM redline)

I was out of Subaru of Santa Cruz and the tech guys there were showing me the oil cooler on the 05 STi. It is right before the oil filter and has a couple lines coming off of it. So, it does come with a factory oil cooler. I was about to buy the oil cooler from you but now I'm not sure...

So I am questioning your guys write up on the gruppe-s oil cooler. Are you saying that this is a better performing oil cooler? or...

gruppe-s

iTrader: (22)

It's a strech to call that an oil cooler. What the tech showed you is a crude heat exchanger. It has very little cooling capacity compared to a proper oil cooler with an air to liquid tube and fin core. I would not even compare the two to one another but I apologize if you feel that we have mis-informed you. If you'd like more information on either the stock heat exchanger or our oil cooler and the benefits of both, please let us know.

Thanks,

Geoff
