Mitsubishi EVO X

The factory location of the ACD pump has been known to cause premature failure of the pump due to its direct contact with the elements. The plate inside of the pump becomes corroded and causes the pump to lose pressure and turn off. This kit allows you to move it into the trunk and keep your pump out of the elements.

Only available with carpeted cover.

All EBC rotors are made from OE spec grey cast iron, exactly as used on new car production and as many as we have tools for are BRITISH MADE wholly in our own UK foundry. Currently EVERY SINGLE ROTOR sold in Europe and the UK is BRITISH MADE and a majority of the designs specific to the USA are also BRITISH made.The British foundry is constantly expanding its in house tooled range but EBC like every brake manufacturer ....does need occasionally to buy some rotors in from approved sources to complete ranges in overseas markets. None of our competitors will ever tell you where their rotors come from and we at EBC are as disappointed as the rest of the world that cost pressure means there is not ONE foundry left in the USA to supply such parts, other brake brands when asked about origin will just sidestep the question. When we do buy rotors in, they are specified, sampled, tested for element analysis, grain structure, tensile strength, hardness and optimum ductility and tested 100 piece by piece to be perfect for runout on this in house machine.

The ETS MAF Intake Includes a huge 5" inlet K+N air filter which feeds the intake pipe via the ETS EVO X MAF adapter which is milled on the ETS lathe for the perfect transition to the inlet diameter of the MAF sensor tube. With a built in dowel pin and precise inner diameter to make a 100% seal with the rubber grommet, this piece installs and fits as if it had a Mitsubishi part number. The system is then braced to the chassis with an aluminum bracket to ensure no movement or vibration. A single-piece mandrel bent 3" intake pipe makes the connection between the MAF and turbo with a smooth transition recirculation fitting for an easy connection to the BOV discharge.

Features:

• 5" KN Filter
• ETS Milled MAF Adapter
• Perfrect Transition From Adapter To MAF
• Blow Off Valve Recirculation Tube
• Includes heat shield to prevent idle surge.
• BOV Vacuum Line
• All Couplers, Clamps and Hardware.
• +56whp when used with a boost controller @ 22psi
• Weight: 3lbs

This 3" short ram intake was designed for use with aftermarket lower intercooler pipes such as the AMS and ETS kits. Also works with the stock lower intercooler pipe. These lower FMIC pipes relocate the BOV return closer to the front of the vehicle, making your factory BOV system useless. Furthermore, removal of the recirculated BOV setup requires additional work, such as a tune. This is not always an option for those budget minded individuals. So a convenient aftermarket option was needed.

The MAPerformance Evo X Intake Kit features a 3" 304 stainless steel tube. Why stainless you ask? It's a well known fact that steel reduces heat absorption compared to aluminum tubing. Lower heat improves power capacity with the stock mass airflow sensor, so our kit will not require tuning or scaling. Capped off with a massive 6" velocity stack, coupled with a high-flow K&N air filter, you'll get maximum induction performance.

Features

• Made from 3" mandrel bent stainless steel
• Works with both factory and aftermarket LICP
• CNC machined MAF adapter plate
• High flow K&N air filter
• 5-ply BOV coupler
• Brushed Aluminum heat shield mounts in factory location
• Includes all clamps required for installation

Benefits

• Friendly for both modded and unmodded intercooler systems
• Works with a wide variety of intercooler piping configurations
• Affordable for all budgets, while performing better than other higher priced intake systems

Mitsubishi Evo X Injector Set: 4x650cc Super FAST Lightweight Custom Modified Saturated / High Impedance Ball & Seat Injectors. Includes pigtails PGT USC4 or add Plug & Play adaptors.

Maximum output on any engine can only truly be achieved when you have complete control over valve train events.  Adjusting the degree of your camshafts, or altering your cam timing has always been a way to maximize performance from your engine.  Alternatively, correcting faulty cam timing has sometimes been a way to find missing horsepower when many have been left scratching their heads.

Cam gears available as a pair, Intake only, or Exhaust only

Features

• Billet Aluminum Timing Adjuster
• Correcting improper cam timing can unlock more hp and tune your hp curve
• Available individually or as a pair

A fuel surge tank (FST) is designed to prevent starvation to the engine on vehicles with inadequate fuel tank baffling. The surge tank also provides a quick and easy way to upgade any standard fuel system without the need to modify the stock fuel tank or pump. It is also an excellent fueling solution for vehicles installing large fuel demand power upgrades such as forced induction. 

PLUMBING
All adapter fittings on top of the FST are 6AN (9/16"-18) male.
1. The internal FST pump directly feeds the fuel rail(s), through the green 6AN bulkhead fitting. The pump outlet fitting is available in -6AN male size only.
2. The 3 black (interchangeable) 6AN ORB fittings are used for the following. 
a. Fuel entering the FST (from the lift pump)
b. Fuel overflowing and leaving the FST (to main tank)
c. Fuel returning from the fuel pressure regulator

NOTES: 
1. An internal flow deflector prevents fuel foam and aeration on all 3 ports.
2. The pumps mount internally using tubing that is gasoline, ethanol, and methanol resistant. 
3. The overflow to the main tank is a requirement on all installations. Tanks without return ports will need customization of the hanger top or filler neck to create a port for the overflow.

How it works

1. Purchase this item. In the comments field, list the year and trim of your Evo X, along with every modification to the car which could effect performance. This includes, but is not limited to engine modifications, wheels, tires, intake, exhaust, weight reduction, fuel system, etc.
2. Depending on the extent of your modifications, you may be required to pay additional fees for your tune. Items such as upgraded fuel systems, turbos, larger MAF housings, and so on will require much more time and calibration, hence, added cost.
3. You will be emailed a starter tune. You will be asked to download this tune to your ECU and log certain parameters in certain conditions.
4. Email us the logs, and you will receive an updated tune. The process of logging and updating your tune will continue until the tune is complete. An entry level tune will have a maximum of 15 versions for the above price.

Note: The tunes are the intellectual property of SpeedCircuit, and may not be shared with anyone without written consent. Furthermore, it is the responsibility of the owner to ensure that the car is mechanically sound. SpeedCircuit is not liable for any damages that may occur to your car. E-Tunes are done at your risk.

Requirements

• Laptop Computer
• Tactrix OpenPort 2.0 Cable w/ EvoScan OR a Cobb Accessport
• If you wish to use the ECUFlash method of tuning but do not have a Tactrix 2.0 cable, you can purchase one here.
• A knowledge and understanding of how a car works mechanically, in order to be able to track down potential issues.
  
• If it is suspected that your car has mechanical issues, you will be asked to address them or have a professional do so.  If you do not look into suspected mechanical issues, we will not be able to resume tuning your car until you do. It is not the responsibility of the tuner to diagnose any mechanical issues.

Recommended

• An Innovate or AEM Wideband O2 gauge with logging cable (required for all non-stock turbo tunes). If logging with a serial cable, we recommend a plugable USB to serial adapter which is available on amazon. If you are going to log via an analog connection, which is the only current way to log via Cobb AccessPort, see here for wiring instructions.
• A boost gauge
• Det cans to hear potential knock with.

What to log

• Wideband (only if you have a wideband O2 gauge installed)
  
• Throttle Position (TPS)
  
• RPM
  
• Load
  
• Boost
  
• Baro (if required by boost)
  
• Knocksum
  
• Timing Advance (ignition)
  
• Active WGDC Correction
  
• Odd Clutch Slip Speed (if tuning SST)

You may be asked to log more items as the tune progresses.

Please be sure to only do one full throttle pull per log. The pull should be from 3200-7000rpm unless specified otherwise.

Warning: E-Tuning requires that the driver of the car be aware of potential issues that may arise during tuning. This may include the car running lean, overboosting, detonating, or any other mechanical issues. If something doesn't feel right, take your foot off the throttle immediately and end the pull. SpeedCircuit, LLC is not responsible for any damages your car may incur! If you are not comfortable with this, please visit us for an in-person tune.

Expect an average of one new tune file per week. This will vary based on both our schedule and how quickly you can provide logs for the most recent update to your tune. There may be times where we may be unavailable, so on occasion there may be weeks where we are not available for e-tuning.

If you're not familiar with how to set up your car or computer to log or flash tunes on your car, or you need help with diagnostics, please check the Phone Support option.

Note: Once an initial base map has been sent to you, there are no refunds.

This video explains our e-tuning process:

Engineered to 'Activate More Grip', sway bars are principally designed to reduce body roll or sway. By reducing body roll, lateral loads are spread more evenly across the tires thereby increasing cornering grip and improving outright performance. This Whiteline 26mm 3 point adjustable sway bar = more grip = better handling = outright performance - it's the best dollar for dollar handling improvement you can make to your vehicle. In fact, benefits extend to improvements in handling, safety and tire wear without affecting ride quality or comfort.

Only the best materials go into the GSC Power-Division Beehive valve spring. Each batch is scrutinized for tensile strength properties, ductility, inclusion content, and fatigue toughness.

GSC Power-Division Beehive springs feature some of the most impressive manufacturing techniques in the industry. Our beehive spring uses an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. This spring has the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Only the best materials go into the GSC Power-Division Beehive valve spring. Each batch is scrutinized for tensile strength properties, ductility, inclusion content, and fatigue toughness.

The beehive valve spring shape has become the buzz lately. Some have enquired as to the benefits of a beehive spring vs the dual springs that are sold by others. While some might find that the beehive spring design is new it has been used commonly in many OE engines as well as in all of the NASCAR and F1 engines of today. Why? The beehive shape is more stable than standard single or dual cylindrical springs. The beehive design which incorporates an ovate wire is more than capable of the performance demands that were previously only matched by a Dual Springs. With the smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control. So beehive valve springs, with there lighter weight retainers allow for engine's to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs of yesteryear.

• Rev faster
• Lighter components
• More durable design
• Less stress on valvetrain components
• Lower spring frequency for more precise valve control.
• More valve control equals more aggressive cam profiles
• All of these items help to return more power for you to enjoy!

The GSC 5042 Beehive valve spring set, and Grade 5 Titanium retainers. This kit is capable of 9500+ RPMS, with as much as 12mm lift cams.
