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.

Use this aluminum plate if you plan on moving your EGR valve to an other place. Will require a gasket and/or RTV to seal against intake manifold.

User needs to provide two of their own M8x1.25 bolts. 10mm to 20mm in length.

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.

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.

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.

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.
