The COBB 3" Turbo Inlet Hose is constructed using four ply steel-reinforced silicone, eliminating the issue of hose collapse that other inlet pipes suffer while under suction at peak demand. While the steel reinforcement provides excellent stability, the silicone allows adequate torsional flex, allowing engine movement on the OEM engine mounts under hard acceleration without risk of separation.  This system uses all factory fittings and clamps.

The COBB Tuning 3" Turbo Inlet Hose is designed for use with 3" inlet turbos, such as the MHI TF06-18K. The bulge design of the COBB Inlet Hose increases the cross-section to 3.5" to maximize air flow delivered directly to your 3" turbocharger, providing much more efficient power and response. The smooth inner walls of the COBB Turbo Inlet taper gradually at both ends and reduce the air turbulence that occurs in the factory accordion style inlet. Designed to work with factory sized intakes.

• 4-Ply Steel Reinforced Silicone    Stealth Black or COBB Blue
• Designed to be used with Stock Intake or Stock-Sized Intakes
• Smooth Inner Walls for Quicker Airflow to the Turbo
• Bulges to 3.5" to Increase Potential Air Flow Delivery
  

Compressor outlet heat shield for Full Race Turbo Kits.

We've installed quite a few Full Race EFR turbo kits in the past couple of years, and have noticed that the #4 runner is way too close to the silicon coupler on the compressor outlet. The couplers will fail from the heat.

Because of this, we have made this heat shield.

There are two different types. A more simple one for the larger frame turbos (8374/9180), and another one, with three sections for the smaller frame turbos, such as the 7670.

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!

Front brake line brackets for the Exomotive Exocet. These are to be fastened or welded onto the frame where the hard line meets the soft line. CNC Plasma cut from 1/8" steel. The small ends have a welded plate with a hexagonal hole to allow the end of the soft brake line to seat.

Includes one pair.

Model Years: 2008 +

Engine: 2.0L 4B11 Turbocharged Inline 4

The Garrett® Evo X Turbo Upgrade allows you to push your AWD, rally-bred monster up to an estimated 750HP+ with the latest technology dual ball bearing GEN2 GTX3576R. Each turbo has been meticulously designed to be a bolt-on upgrade with no fabrication, cutting or welding required.

This Evo X Turbo Upgrade features a specially designed twin-scroll turbine housing that mates up directly to the Evo X's stock exhaust manifold as well as the stock exhaust down pipe to allow for aftermarket exhausts to be used without worrying about fitment.

The turbine housing allows for the retention of the stock exhaust heat shield for better temperature control as well as a stealth look.

The ported shroud compressor housing reduces the occurrence of surge during operation and mates directly to the intake piping as well as the stock outlet position.

The Garrett® patented dual ball bearing center housing is standard on both turbocharger options for unmatched power handling and unbeatable response.

The Evo X Turbo Upgrade is a powerful, yet highly streetable enhancement to an already potent car.

We recommend this compressor inlet with this turbo.

GEN2 GTX3576R:

• Horsepower (estimated) 750+
• Compressor Wheel Inducer 58mm
• Compressor Wheel Exducer 76mm
• Compressor Wheel Trim 58
• Compressor Housing A/R 0.60
• Turbine Wheel Diameter 68.0mm
• Turbine Housing A/R 0.94

Kit Contains:

• Garrett GEN2 GTX3576R dual ball bearing application specific turbocharger
• Inlet elbow
• Oil drain line
• Water lines
• Gaskets and necessary hardware
• Installation Instructions

PLEASE NOTE: Turbos with BIG wheel combinations such as these require good airflow in and out of them in order to do their job efficiently. Whenever possible, run the largest diameter inlet piping (3" preferred) to allow adequate airflow into the turbo and 3" diameter piping out of the turbine exhaust to facilitate maximum flow. Allowing the turbo to inhale and exhale freely through large piping work will allow you to attain the desired HP easier with often much less boost pressure during your tuning process. Failure to free up the turbo's flow potential can force the turbo to "top out" in power prematurely and undoubtedly place your entire engine/turbo against the perpetual "wall" and always short of reaching maximum power.

• P.E.P. manifolds are 304SS throughout! Never worry about rust or failed coatings.
• Utilizes 1/2″ flanges 4 mm thick walls to ensure strength with a low weight
• Positions the turbo in the stock location and is flanged for all T2 turbos (including but not limited to the stock turbo)

• An O2 bung in the collector for the stock primary O2 Sensor
• An EGR fitting which is positioned so that you can reuse your stock EGR tube, but the tube may need some slight adjustments in position for a perfect fit.
• 8 x socket cap bolts to replace the factory manifold bolts or optional upgraded stainless bolts or ARP stainless studs and nuts

• Use Anti-seize on all exhaust hardware
• Use optional studs wherever possible
• Cut the short end of an allen wrench down to about 0.75″ in total length so it can fit into some of the tighter spaces (such as the center bolts)
• Ball end allen wrenches will be very helpful throughout the install.
• The M20 threads on the EGR fitting can be very difficult to start especially if the alignment isn’t perfect. To make things easier loosen the EGR tube support bracket near the water neck and the nut at the intake manifold. With these loose, it becomes very simple to get the EGR fitting started at the exhaust manifold. Snug everything down once all threads are started.

• 3" Piping size to support up to 450whp.

Now get up to speed with two great products for one low package price!

On our car, we gained 72 extra horsepower to the wheels on a Mustang Dyno. Please note that Mustang Dynos tend to read about 10-13% lower than a standard DynoJet.

We achieved this on a hot summer day on 93 octane fuel. The car has zero driveability issues, and is much smoother and faster than stock. Simply put, it's a whole new car.

This is the perfect solution for someone who wants a stealthy yet serious modification to the car. Aside from the large power gains, it is virtually undetectable by anyone, including dealerships. If you're concerned with keeping your warranty intact, this is the product for you.

When ordering, Please be sure to specify the octane of fuel you will be running. Please specify your performance modifications as well. Also be sure to choose how aggressive you'd like your tune to be.

Mild - Good gain in power, however conservative and very safe. If you're not obsessed with making top performance numbers, this choice is for you. This tune runs richer air:fuel ratios and less aggressive timing.

Medium - Better gain in power, more aggressive. This runs less rich and more aggressive timing than Mild.

Spicy - Almost as aggressive as hot. Essentially this is a "Hot!" tune with slightly less timing.

Hot! - Best gain in power, however the most aggressive. This flash runs air:fuel ratios and timing numbers for optimal torque and horsepower. It is STRONGLY recommended that your car is equipped with a wideband air:fuel gauge if you are considering this version of the flash.

You have three options on how to attain this flash.

Option 1 - Make an appointment to have your car flashed, and come see us. Aside from your driving time, this option only takes about 20 minutes to complete.

Option 2 - Mail-in flash. Remove the ECU from your car (instructions to be posted shortly) and ship it to us. You may want to ship it via an overnight carrier as to have your car down for a shortly as possible.

Option 3 - E-tune. You will be emailed a ROM for use with a cobb accessport or ecuflash tactrix cable. This requires you to have at least one of the aformentioned tools.

While all of our flashes are extensively tested to produce good gains without any negative consequences, it must be noted that they are to be run at the risk of the customer.

The SpeedCircuit Hotpipe (Upper Intercooler Pipe) is a single piece 2.5" mandrel bent 304 stainless steel pipe (instead of cheap aluminum or 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 of this pipe include

• Improved throttle response
  
• Small power gain
  
• No more stock hotpipe expanding under boost
  
• Smoother power at the top of the RPM range
  
• Replacement of stock rubber hose which allows you to mount BOV flanges and other accessories and bungs.
  
• A show-quality piece to set your engine bay apart from the crowd.
  
• The fastest, easiest install hotpipe on the market today.
  
• A part that will last the lifetime of the car.
  
• Silicone hose couplers available in Black, Blue, and Red!

Note: By default, the pipes do not have any type of finish. We offer this by default in order to save you money by giving you the option to finish it any way you'd like. For an additional fee, we can offer a brushed finish, a polished finish (as pictured above) or a powder coated finish. You can even have us polish and powder coat the same pipe!

Additional options include

• Weld-on BOV flanges for Greddy Type S/RS and HKS SSQ-V
  
• Brushed finish
  
• Polished finish
  
• Powder coated the color of your choice
  
• 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. Many options are available for finishing, so feel free to ask us about your custom idea!

Running a lot of boost? Need more fuel in your engine? Here's your answer. Included with this manifold are four additional ~330cc injectors. Combined with your stock 280cc injectors, you'll have more fuel than you'll need.

An extra injector per runner means that you'll get an even distribution of fuel among all cylinders, rather than the pre-throttle body injector setups which may cause certain cylinders to run richer and others to run leaner.

For an additional $250, you can upgrade to a brand new single runner 626 intake manfiold for better airflow and more power.

(Stock injectors, fuel rail, and hoses not included)

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

Our bench flashing service can restore your bricked ECU or apply one of our canned tunes to get you going with your mods. If you're local we can remove the ECU for you if you prefer or you can mail it in and have it mailed back ASAP.

Have a bricked ECU? Don't have access to a Tactrix cable, but need a tune flashed? Need to downgrade your ECU to a different year or go from MR to GSR after a 5 speed swap? Well we have a solution for you! With our bench flashing service we can recover your bricked ECU and/or flash one of our canned tunes during the process. Now you don't have to panic when things go wrong or you cut corners and let your buddy give you a "custom tune."

Our wiring trays are 2" deeper than those available from Exomotive. If you plan on putting a lot into your wiring tray, especially if you're using an ECU which is taller than the Miata ECU, this is a must have.

In our shop car, we are running the OEM GM ECU for the 2004 GTO, and the ECU is too tall to fit into the tray. After talking to some other folks, we learned that we're not the only people with this issue.

Our trays are laser cut and bent by a computer controlled bender. The lid will be included, as will free shipping within the lower 48 states!

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.

• 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.

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 immeidately 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 two new tune files per week. This will vary based on both our scheudle and how quickly you can provide logs for the most recent update to your tune.

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.

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

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 will be an optional upgrade from the standard 9.5" wide fender.
• 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 siginficantly 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

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.

• Currently these do not fit cars with ABS. However, we are working on a solution.
