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.

Installation instructions

This aluminum valve cover will not melt like the plastic ones, and will allow the valve cover to Powder Coated!

This is the OEM valve cover on from the 2008 Evo X which Mitsubishi later changed to plastic in order to cut costs.  It is compatible with all Evo Xs.

Includes Valve Cover Gasket as well as spark plug gaskets.

These are brand new valve covers, and if you decide to have us powder coat them, we DO NOT sandblast them like some other shops do. They are simply prepped and then powder coated.

We also recommend one of our spark covers to keep heat away from your coil packs, and to give the valve cover a nice, complete look.

Please note that valve covers are powder coated to order, so please allow time for this.

Optionally, you can replace your crusty old valve cover bolts with out Valve Cover Bolt Kit!

Powder coated valve covers are not returnable or refundable, as they are considered to be custom.

Lower your rotating mass in style with this billet aluminum power steering pump pulley!

Features include

• 1/2lb lighter than OEM
• CNC machined aluminum part
• Available in several finishes
• Won't rust like OEM
• Attractive pulley design looks great under the hood

The OpenPort 2.0 is Tactrix's newest tuning tool hardware that is capable of communicating with most OBDII compliant vehicles using a standard J2534 interface. Combined with the EcuFlash software, the OpenPort 2.0 is capable of reflashing a large number of newer Subaru and Mitsubishi vehicles, and support for other cars is in progress.

We include a USB cable with each OpenPort, which is all the hardware you'll need unless you have one of the few vehicles that require a separate reflash adapter. For Subaru you'll only need a reflash adapter for the 2001 through 2005 WRX, but not STi, unless you're working on an early non USDM STi in which case you made need one of our WRX adapters. No other Subaru vehicles require reflash adapters including Forester, Baja, Legacy, or naturally aspirated Impreza models. For Mitsubishi, you'll need the adapter for most pre CAN vehicles which include the 5-9 Evo. Choose the adapter you need from the 'Reflash Adapters' drop down list on the right side of this page.

Have your car professionally tuned by Dino @ SpeedCircuit via email.

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.

If you're making over 400whp, you'll want these upgraded pulleys to keep your serpentine belt intact! The Mitsubishi OEM pulleys are made from plastic and will permanently distort with big power, causing your belt to walk and shred time and time again. Don't leave yourself stranded and constantly in need of a new belt. Fix the problem by installing these steel pulleys.

Note: The pulley that goes onto the OEM belt tensioner will require the use of the provided washers to ensure proper the clearance for the pulley to fit.

The SpeedCircuit Hotpipe (Upper Intercooler Pipe) is a single piece 2.5" mandrel bent stainless steel pipe (instead of cheap steel that some competitors use to save money). Rather than slimming down the diameter halfway through the pipe like the factory part, our part remains at 2.5" the whole length of the pipe!

Benefits and features of this pipe include:

• Improved throttle response
• Small power gain
• No more stock hotpipe expanding and popping off under boost
• Smoother power at the top of the RPM range
• Engraved SpeedCircuit logo
• Replacement of stock rubber hose which allows you to mount BOV flanges and other accessories and bungs.
• T-Bolt clamps for a superior clamping strength.
• A show-quality piece to set your engine bay apart from the crowd.
• A part that will last the lifetime of the car.
• Reinforced silicone hose couplers

Additional options include:

• Weld-on BOV flanges for Greddy Type S/RS and HKS SSQ-V
• Specialty Powder Coating - You can also choose to do multiple types of finishes.

For example, you could do a polished finish, and on top we can do a black chrome
powder coat over it which will tint the polished pipe black. We also have wrinkle and high temp powder coats available as well. Many options are available for finishing, so feel free to ask us about your custom idea!

XXL firewall heat shield helps prevent heat and fire damage.

Benefits and features include:

• New XXL version designed to fit with large turbo setups, even those with large external wastegates such as the Full Race and ETS turbo kits.
• Designed to help prevent any firewall fires
• Constructed from stainless steel with a mirror finish
• TIG Welded for superior strength
• Install in minutes thanks to outstanding fitment
• Protects critical components such as wiring, ABS system, AC system, and more
  

Please note: The XXL version requires you to remove two small 6mm studs on the firewall, in addition to a square rubber grommet.  Installation guide to come. With some turbo kits, trimming of the bottom left of the shield by a few inches may be necessary for downpipe clearance. The last image will show the measurements required to trim the shield for the ETS Turbo kit. 

Instructions to trim this are as follows:

1. From the horizontal break, measure down on the left side of the piece 7" and place a dot.
2. From the horizontal break, measure down on the first bend 5" and place a dot.
   
3. From the horizontal break, measure down on the second bend 7" and place a dot.
   
4. From the previous dot, measure to the left 1.5" and place a dot.
5. Connect all of the dots from left to right as shown in the photo.
6. Cut on the line you created. This will allow space for the ETS downpipe to clear while still protecting the lines behind the shield.

If you plan on running this shield with a large turbo kit, it may be necessary to install this before the turbo kit.

Stainless steel heat shield for your exhaust cam sensor. Designed to protect your cam sensor from damage, especially when running tubular manifolds where the runner is very close to the sensor. Fits any manifold we've tried so far, even the Full Race!

The SpeedCircuit Automated Super Sport will automatically make your Evo X MR or SE start up with the SST transmission in Super Sport Mode. SST cars which are making significantly more than factory torque should always be run in Super Sport Mode, due to it's increased clamping pressure. Failure to do so will result in excess clutch slippage and short clutch life.

Avoid the hassle of manually putting your car into Super Sport Mode! The factory transmission mode switch will still retain all functionality and will allow you to choose Sport and Normal modes if desired.

Compatibility: This device is made for the Evo X MR and Evo X SE. It will also work with a Lancer Ralliart that has been converted to have Super Sport mode.

Installation Guide:

Form meets function with these track tested fenders for your Exocet! #deathmachine tested and approved!

These are made to order, so expect a 2-4 week lead time on average.

Specs and Info:

• The mounts are made from 1/2" steel rod with plate steel flanges. They are fully bolt-on, front and rear
• The mounts are suspension mounted, and move with the wheel
• This kit can accommodate anything from a +25 offset wheel with 205mm tire on them all the way to a 275+ mm tire with a negative offset. For more information on fitment, see our fitment list below.
• The fenders pictured are 11.5" wide, which were an optional upgrade from the standard 9.5" wide fender. Neither of these sizes are available anymore. They have been replaced by 8.5" and 10" options, to better suit most people's needs.
• The fenders are 1/8" thick aluminum
• By default, they will cover a stock NA/NB Miata tire diameter of 22.7". This will work well for a variety of sizes, for example a 245/40/15. To check your tire diameter, you can either check with your tire manufacturer, or use this calculator for an estimate.
• f your wheel diameter is significantly different from the stock 22.7" diameter, you may want to use the DIY option, which will allow you to customize your bracket height. This will require welding and a lot of time to set up properly.

Please watch the video below for installation instructions:

Fitment List:

While we cannot guarantee fitment with this kit and the unlimited combinations of wheels, tires, spacers, and suspension, we will try to occasionally update this list of known examples regarding fitment. If the brackets do not fit your wheel setup, it can mostly likely be fixed by using a spacer and extended wheel studs. Alternately, you can return the kit, but you will be subject to a restocking fee.

Modification is required to the rear bracket in order to fit an NA miata donor. The bracket must be ground down to fit.

Fits (YMMV):

• Japan Racing JR19 wheels, 15x10.5 ET-32, Hoosier A7 275/35/15, front and rear shock spacers - Plenty of clearance to the bottom of the fender and to the bracket.
• Team Dynamics wheels, 15x8 ET25 with 10mm spacers, 205/50/15 tires
• JNC 003 wheels, 15x9 ET0,245/x/15 with 5mm spacer - clears fine, spacer was required to clear rear brake calipers
• OZ wheels, 16x7 ET36 with 25mm spacer in the rear and a smaller spacer in front, 2015/x/16 Hoosier R7 tires
• 215/40/17 tires are a close fit
  

Does not fit:

• Custom wheels, 15x11 ET0, 295/35/15 - The inside of the tires rub the fender brackets. They should clear with a 15mm spacer.
• 6UL wheels, 15x9 ET12 - The inside of the tires rub the fender brackets. They should clear with a 15mm spacer.

CFM Performance now makes it easy to vent the crankcase on your 2008-2015 EVOLUTION X 10 & 2009-2015 RALLIART with our new billet valve cover baffled breather kit. This kit is a direct replacement for your factory oil fill cap and allows unwanted crankcase pressure to exit.

This breather is the ONLY one in the market which incorporates a check ball to keep unmetered air from coming through while the crankcase is under vacuum. In other words, this breather acts just like a factory oil cap under normal driving conditions and when you get into boost it will release any crankcase pressure present. The proprietary internal baffle substantially reduces oil particle travel without affecting air flow. The filter element is washable and has a variety of top finishes for great looks. The pre-oiled cotton fiber traps dirt particles without restricting air flow. Although this kit was designed for use in racing applications, it works and looks great in any engine compartment.

After listening to customer suggestions and with help from Dino at SpeedCircuit, SSP has come up with the most comprehensive solution for replacing the oem plastic under panel currently available. Not only did they address the issue regarding the high shipping costs by making this a two piece unit, but they have also managed to incorporate a front jack point location. All this while maintaining the structural integrity and level of protection you would expect from a SSP Under Panel.

Specs:

• 14.0 lbs total weight!!
• 6061 Billet ALUMINUM CONSTRUCTION (2.2mm thick)
• Powder Coated (Black ONLY)
• Oil filter/Oil Drain plug access panels
• All New Front Jack Point Location
• All New 2 Piece Construction for lower shipping costs
• Added louvers for additional cooling benefits.
• Comes with all hardware and fittings needed
• Replaces 100% of the OEM plastic under panel
• Fits most aftermarket spoilers

Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP® head studs are popular among leading Sport Compact/Import racers. You should know that ARP® uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It's important to note that lesser quality studs are not even centerless ground—the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP® studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned—something that won’t happen with inferior quality head studs. ARP® studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat. Premium parallel ground washers and Hex nuts (10 each) are also included with each kit. ARP is the leader in fasteners for racing and high performance. More winning teams use ARP fasteners than all others combined. Top quality, exact tolerances, the best materials and machining processes, and the ability to survive the rigors or racing and get you in the winner's circle make ARP fasteners the #1 choice.
