Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each motor Cometic offers a number of options to suit your specific motor and needs.

*MLS*

The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it’s ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. The Viton coating is heat resistant to 2500C or 4820F.

The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.

The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.

Turbomotiv has manufactured a solution for EVO X owners that have experienced failures in the factory MIVEC exhaust cam gear housing after installing upgraded valve springs. It has been noticed over time that the stock cast aluminum housing will develop cracks in key areas that can cause a loss of MIVEC control when valve spring seat pressure from upgraded valve springs is increased or during loss of oil pressure. By enlarging the overall diameter and CNC machining it from billet 6061-T6 aluminum, they have increased the overall strength of the piece, making it more resistant to failure.

• CNC machined from billet 6061-T6 aluminum
• Does not include the factory phaser, gear, hardware, spring or retaining pin

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.

Revised and upgraded OEM timing chain for the Evo X. Since the original OEM timing chains were prone to stretch, Mitsubishi released heartier this timing chain to minimize stretch and increase lifespan.

ClubSpec Custom Design Hood Strut Kit was designed to provide a high quality option. The bracket designs allows proper distribution of weigh and a sturdy mounting point. CS utilizes commercial grade struts to ensure that they work in all weather conditions including sub-zero temps.

Oil Chain for the Evo X

This is a simple yet elegant solution for 4B11 owners who have experienced failures in the factory MIVEC exhaust cam gear housing. The stock cast aluminum housing are prone to failure due to increased valve spring seat pressure from upgraded valve springs.

This replaces the stock phaser, but is fixed at the 0° position. This will require your exhaust MIVEC target maps to be set to 0 in your tune to avoid a check engine light. During testing, we have not found exhaust MIVEC timing changes to have an impact on power, so having them set to 0° results in no performance penalty.

Effectively, this deletes MIVEC on the exhaust cam.

• No sealant required
• 90mm bore
• MLX technology
• No re-torque necessary

COMETIC MLX (Multi-Layer Stopper) gaskets utilize an integrated stopper layer for combustion chamber sealing and improved clamp load around the cylinder without increasing bore distortion. MLX technology can be found in some head gaskets and are made from the same materials as our MLS Head Gaskets. No sealants or re-torque required.

This head gasket is 1.37mm (.054") thick while the stock head gasket is is 1.1mm (.044") thick

GSC Power-Division Super Alloy Exhaust Valve for 4B11T

Set of 8

STD Size 29mm

These valve springs are required for Kelford 214-B and 214-C springs.

Valve Spring Specs:

• Outer O.D.: 0.965"
• Outer I.D.: 0.669"
• Closed Pressure: 77 lbs
• Closed Height: 1.378"
• Open Pressure: 165 lbs

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

Part #

• MMCENG1080 – Both Intake and Exhaust
• MMCENG1080I – Intake 
• MMCENG1080E – Exhaust

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!
