Power Packages

ENGINE PERFORMANCE

Our goal is to provide 'Real World' Performance Upgrades for your 2.5RS/TS, which will allow you to increase performance up to and over a WRX, using your normally aspirated engine as a base.

The upgrades run on pump gas (93 Octane) and use the OEM ECU and/or a Piggyback ECU.

Our upgrades are designed as an alternative to turbo charging the 2.5L engine, or you can add a turbo kit for that BIG POWER you are seeking.

Also, the power upgrades in this section can be used on your new Legacy, Legacy Outbacks, Foresters and and Baja 2.5L engines. Some parts are model specific and others require some fabrication.

You will need to contact us for Legacy, Legacy Outback, Forester and Baja applications.

Please note, all power outputs stated below can vary depending on vehicle condition, fuel and modifications. All Modifications are for Off-Road Use Only. All cams, except the .445s, are regrinds, heads and short blocks are custom built and all are considered racing parts, therefore do not carry any warranty period. In no event shall Xcceleration.com be liable for any warranty, labor or service charges whatsoever.

Please be patient, certain parts are made per order and require time to manufacturer. All parts will be immediately shipped as they become available. All prices do not include any core charges, shipping or installation charges.

HOT STREET-Race CAMS: SOHC .410 and .445 lift

For Non-Turbo and Turbo Applications

Power of Turbo Charging, with the Reliability of a Non-Turbo!

.410 lift Hot Street Cams are designed specifically for street cars, which are naturally aspirated. We have designed the cams for 'real world' street application, using the factory ECU and OEM intake and exhaust. The camshafts are designed to provide a great idle and increase the overall performance of the engine.

Power over the entire r.p.m. range is greatly improved. You can see gains in HP of about +20HP at redline (6500 RPM), on a stock engine. Even more is possible when performance intake, exhaust system and engine management are added.

.445 lift 'Hottest' Billet Street-Race Cams are designed for naturally aspirated and turbo charged applications. The .445 cams are new 'Billet' cams, not regrinds. They provide intense mid and high range torque, with a good idle and awesome performance. Engine Management, FPR and increased injector size are required.

• Power will begin at about 3200rpms and continue to redline (6500 RPM).
• You can see gains in HP of about 30+HP on a stock engine with engine management.
• When used with a performance intake, header, performance cat, and cat back system, you will see gains in HP of about 60+HP!
• If you add our performance heads, you will see gains in HP of about 80+HP!!

See more HP in turbo charged applications.

All cams are for 2.5L SOHC engines, '99 +

*Please be patient, cams are made per order and take about 4-6 weeks to deliver. .410 cams are reground to our specifications, no core charge is necessary. .445 cams are new 'billet' cams, no core charge is necessary. All shipping is the responsibility of the customer.

HOT CYLINDER HEADS

Hot Big Valve Cylinder Heads

Designed for

Intense LOW and MID RANGE TORQUE!

Intake: 22% Increased Flow (max)

Exhaust: 41% Increased Flow (max)

Providing over 40 HP+ depending on your application. The hot cylinder heads increase air flow for stunning performance. The Hot Cylinder Heads receive competition porting, polishing and multi-angle valve job, for maximum performance.

A graduated port finish maintains boundary turbulence for maximum fuel suspension while allowing maximum laminar velocities at the valve seat at all lifts. A properly shaped valve seat/port juncture in conjunction with proper combustion chamber modifications, help ensure maximum volumetric efficiency (cylinder filling). This will show dramatic flow increases at all lifts. Midrange and bottom end power will show serious gains and when coupled with complimentary intake modifications, a large top end increase will also be realized.

Pricing includes the following (using customer supplied cylinder heads):

1. Port refinishing and bowl contouring.

2. Custom 5-angle valve seat machining. Angles are chosen to match the specific porting.

3. Hand blending of the port/valve seat juncture.

4. Combustion chamber cleaning.

5. Milling of the cylinder head (skim depth).

6. Valve resurfacing using the ‘center-less’ method which also measures the stem and head run-outs to 0.0004”. Valves are replaced if this run-out is exceeded.

*$6,999. (using customer supplied heads)

*Price does not include processing fees, and shipping. Please be patient, each engine is made per order and takes about 6-8 weeks to deliver. All shipping is the responsibility of the customer. All head work is to performed on customer's heads only, and are not available for direct sale. If new heads are requested, $1500 will be added to above pricing.

TURBO KITS

Subaru Impreza 1.8, 2.0, 2.5 ENGINES 1993-2007

Some fabrication required

If you are looking for the ultimate in high performance - this extreme performance packages are for you. Providing the maximum horsepower for the very discriminating and still providing dependability for daily driving. Incorporating all the high performance equipment in a superior performance package, this extreme package includes: an intercooler, pop off valve, and piggyback ecu control unit (The Brain) and more. This offers complete control for your system, increased fuel delivery, and cooler temperature gas air mixture for better burning.

The Stage 1 Turbo kit :

- Garrett GT28R turbo and manifold pre-assembled
- Down pipe, catless mid pipe and gasket (upgrades : performance converters (cats) and catback exhaust)
- Polished charge piping (uppipe)
- High flow front mount intercooler
- Stainless steel braided oil line and fittings
- Stainless steel braided water lines for turbo cooling
- Rising rate fuel pressure regulator
- Blow-off valve (atmosphere)
- Piggyback ECU unit : ("Live Tuning")
- Heat shield
- Air intake tube (from turbo to stock air box. Upgrades : performance intake to replace stock air box)
- Oil return hose and oil pan fitting
- All hardware, pressure lines, hoses, clamps, and couplers, plus performance exhaust header included

Contact us for additional performance upgrade information and pricing.

This is a high quality factory kit that surpasses all the home made kits available. The kit includes a Garrett water cooled ball bearing turbo, front mount intercooler, blow off valve, stainless steel performance header, and more.

We recommend 6 PSI of boost for safety and reliability and puts the Horse Power at about 260 HP range at the engine. About 100 horsepower over stock. This makes the car very fast and considerably faster than a WRX as it has more horsepower and is a lighter car.

You will need to increase your injector size , modify your fuel rails and fuel system plus

consider upgrading your converters, catback and stock air box to a performance intake.

Constact us for information and costs.

The Stage2 Turbo kit : adds a STi Short block, STi pistons, rods, crankshaft; short block fully assembled (does not include gasket kit) and a piggy back ECU for live tuning. Using this block will allow the 6psi recommended for the Stage1 Turbo kit to be increased up to 18psi, to see about 400hp for an insane power increase!

Note: fabrication is required for fitment, and extra modifications are required when tuning the boost up above 6psi, including upgrades to injectors and fuel system.

You will need to increase your injector size , modify your fuel rails and fuel system plus

consider upgrading your converters, catback and stock air box to a performance intake,

as well as, your clutch or torque converter.

Constact us for information and costs.

The Stage3 Turbo kit, only for 2.5L SOHC Engines : adds our .445 Hot SOHC Cams for intense mid and high range torque. Using the .445 cams will add about +60HP to the mix and make an insane power increase!
