FEATURE / SPEC
■ SUPER GROMMET DESIGN
The sealing performance has been improved considerably with the super grommet,to suit these engines and has been proven to brliver excellent relibility.
 |
SUPER GROMMET TYPE
The dual sealing method of the bead structure & metal grommet, provides maximum sealing for the coolant, oil & gases around the bore circumference. |
■ Heat Conductivity & The Strength of Stainless Steel
Stainless steel was chosen to be the material of choice to make the Metal Gaskets with because of the heat conductivity efficiency of the stainless steel material to evenly distribute the heat and aid with cooling. This will greatly improve reliability and reduce the chances of problems.
The natural high tensile qualities of Stainless Steel greatly helps with increasing the joint ridged of the cylinder head with the cylinder block. This helps minimize the engine from warping when under severe stress loads that performance engines go through when running high power applications. The result is improved durability and added power gains.
■ ABOUT MARKING
All our metal head gaskets are laser marked with Models, Bores, Thickness, and TOMEI POWERED INC. company name.
Since there are similar/counterfeit goods on market, please make sure logos on Gasket. |

In order to make cam clearance maintenance-free and quieter operation sound, the hydraulic lash adjuster was adopted for the SR20 engine. However when aiming at higher RPM ranges and for higher horsepower output from engine modifications, it is important to improve the reliability of head system parts and to make valve drive train set correctly for the suited cam profile. So it is necessary to eliminate the use of the hydraulic lash adjusters. We have adopted the solid pivot system to enable adequate cam clearance adjustments while keeping total height of pivot of each cylinder fixed. Therefore it is possible to build a more precise head system in a shorter time compare to the other conventional methods. Improvements in the reliability and lower pricing were made possible at the same time by having reduced the number of parts required.

We chose to use Phosphor Bronze (Cn-Sn-P alloy) to make our Valve Guides, for its highly tensile and superior heat transferring ability, which is vital in high power and high RPM outputting engines. Since race engines these days require more power at higher RPM use , these engines now experience more extreme heat conditions. These conditions will increase the deterioration rate on these valve train related components. The Phosphor Bronze material has exceptionally lower friction and the best possible clearances can be maintained, which will reduce the stress on the valve train assembly, prevent seizures and cracking under high-stress loads.

Still since the product will be used for extreme conditions, it will still require additional regular maintenance and periodical checks. The product can wear out faster under certain conditions. Some examples of the abnormal conditions are as follows.
■The rocker arm type assemblies will apply more lateral pressure, which will increase the wear rate. If the stem wall of the valve is rough, it will also contribute to the increased wear rate.
■Using high lift, aggressive camshafts will also increase the wear rate.
■Excessive buildup of carbon will also hinder performance and increase wear rate. When there’s a small opening at the end, it will increase the carbon buildup rate as a funnel effect.
■The results from Valve Spring surging will cause the Valve to move on an angle. This will cause both ends to open up and create deformation. Then carbon can enter the valve guides more which will increase the wear rate.
■A defective seat cut. When the seat cut’s centerline across the main 45 degree face is offline from the valve stems centerline by more than 0.01mm, this can cause increased abnormal wear rate.
■If the clearance is not within the correct 0.03-0.04mm range. The Valve will rub against the guides inner wall, this degree angle in relation to the seat cut will cause it to shift by 0.01mm more than the clearance values. The guide will take the lateral pressure point and open up the opening. The buildup of carbon will increase in the newly formed gaps.
■A worn out used Valve. It’s possible to cut down by using the part that has not worn out the stem when changing to a high lift cams. The guides can wear out when the inappropriate clearances are made. (About 0.01mm out of clearance).
■The Valve design is defective. The difference from the dilatability and the guide being worn out abnormally is when the valve that is made with different alloys, will contribute with a faster deterioration.

■ Multi Coil Unequal Pitch Springs
By combining several steps of spring rates into the one spring and vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging. 
■ Advanced Oil Tempered Chromium-silicone Alloy Steel Core
Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further. Combined with a new optimized design, not only did we make it tougher, we also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.
■ Shot Peening
A process that strikes many small steel balls onto the surface of the spring at high speeds is made to enhance the surface of the spring to raise its fatigue limit. Although it has been carried out earlier during the manufacturing process.
■ Warm Setting
The process that is adding higher loads beyond the actual limits to the highly heated spring. This will modify its shape and keep it permanently fixed. We succeeded in securing the highest performance over a long period of time while preventing sagging.
■ Nitriding
The surface treatment method for making nitrogen permeates the spring and gives it large surface compression repulsion. This method was chosen to raise the fatigue limit to suit the demands or running high lift camshafts. The dangers of spring failure is greatly reduced with the 1.5 times increase in the springs fatigue limit with the combined use of Oil tempered chromium-silicone alloy steel wire and Nitriding. This is how our valve springs are suitable for use on extreme engine speed conditions of super-high revs exceeding 10,000 RPM which had not been previously possible with high lift camshafts.

FEATURE / SPEC
■ These products are designed and produced in cooperation with Australia’s ACL Bearing Company, which supplies engine bearings and various engine components as OEM to various automotive manufacturers.
MATERIALS
 |
The combination of these material enhancements optimize bearing performance under high loads and temperatures.
OVERLAY （P76 Material）
The P76 material is used for it’s superior abrasion and fatigue resistance. The elimination of the tin flash plating improves the heat transfer through the bearing.
F781 Material
The F781 material is used on connecting rod bearings for high performance engines. It has a hardened steel backing to improve the support of the bearing lining and assist bearing retention in the housing. |
CRUSH
 |
The Competition Bearing Series are designed with an increased crush (i.e. extra bearing length of typically 0.100-0.175mm). The extra crush improves the retention of the bearing in it’s housing.
Crush Height: The crush height is based on the bearing being a fraction longer than the housing seating so that a small section protrudes above the rod bore parting surface. When the rod halves are drawn together, the inserts touch before the halves, thus forcing the inserts tightly into place. |
ECCENTRICITY
 |
The wall thickness at the crown of the shell is thicker than the wall at 3/8″ down from the parting face. These Competition Bearing Series have an increased amount of eccentricity to compensate for the bearing housing bore elongation in extreme conditions and to help create an effective hydrodynamic oil film. |
LOCATING TANGS (NOTCHES)
 |
These Notches help with bearing alignment during fitment. They do not hold the bearings in place during operation, that is the function of “Crush”. |
BORED SURFACE
 |
The bore bearing surface finish method helps promote effective oil flow and to maintain adequate lubrication for both the bearings and other moving parts. |
BORED SURFACE
The design of the oil grooves on the lower main bearing shell is always a trade off between oil supply to the Conrods and the bearings load carrying capacity. These TOMEI Competition Bearings generally have a 3/4 groove to give optimum balance of oil flow whilst keeping optimum load carrying capacity.
The reason why TOMEI Competition Bearing Series do not have the final tin flash plating.
General standard grade bearings will have a Tin flash plating over the entire bearing to give them the grey silver finish. Since these bearings are designed for high end race purposes, the use of the final tin flash is not required as it gives no added benefit. Therefore, these bearings may show different colouring, which is normal.
The disadvantages of using the Tin Flash Plating are 1. Heat dissapation will be reduced. 2. The tin on the bearing back can act as a lubricant at high temperatures, and reduce the friction between the bearing and its housing. 3. At high loads and temperatures the tin plating on the bearing back can break down and “pool” to create hot spots.
To ensure the optimum bearing performance, the TOMEI Competition Bearing Series has not adopted this type of final tin flash plating. Thus the appearance of uneven colouring on our bearings. This poses no issues with performance and bearing efficiency so please do not be alarmed by it. There is a protective oil coating administered during packaging for protection against the elements. Please remove this oil coating prior to use. The protective oil coating will allow the bearings to have a storage shelf life of up to 3 years.

During the development of the ARMS turbines we also checked the suitable fuel setup, camshafts, compression ratio and collected the right data and setup with the REYTEC and TOMEI ECU. We found the best balance not only for the engine bench dyno but also for the daily driven Sports car use. The data collected during R&D proved to be the best balanced all round performance for street use and even at event days from Time Attack to Drift after being analysised from data logging.

To truly enjoy the FA20 is to extract the most from it in NA form. So maximum weight reduction is an essential part of it. This product is specifically designed for competition use. With the absence of a catalytic converter, the pipes made from Titanium, this drastically reduces the overall weight to compliment the power gains.
When fitted to a car that has a forced induction setup, it greatly enhances the performance gains with the improved exhaust flow efficiency. This is one of the key products to extract the performance potential of the 86/BRZ/FR-S.

■ Multi Coil Unequal Pitch Springs
By combining several steps of spring rates into the one spring and vibration frequency becomes amazingly high. This greatly minimizes resonance and the chances of surging. 
■ Advanced Oil Tempered Chromium-silicone Alloy Steel Core
Oil tempered chromium-silicone alloy steel wire is used which is considered to be the best material for springs for performance applications and evolved it even further. Combined with a new optimized design, not only did we make it tougher, we also succeeded in suppressing valve jumps or bounce even when raising the engines speeds RPM limit.
■ Shot Peening
A process that strikes many small steel balls onto the surface of the spring at high speeds is made to enhance the surface of the spring to raise its fatigue limit. Although it has been carried out earlier during the manufacturing process.
■ Warm Setting
The process that is adding higher loads beyond the actual limits to the highly heated spring. This will modify its shape and keep it permanently fixed. We succeeded in securing the highest performance over a long period of time while preventing sagging.
■ Nitriding
The surface treatment method for making nitrogen permeates the spring and gives it large surface compression repulsion. This method was chosen to raise the fatigue limit to suit the demands or running high lift camshafts. The dangers of spring failure is greatly reduced with the 1.5 times increase in the springs fatigue limit with the combined use of Oil tempered chromium-silicone alloy steel wire and Nitriding. This is how our valve springs are suitable for use on extreme engine speed conditions of super-high revs exceeding 10,000 RPM which had not been previously possible with high lift camshafts. 
High lift camshaft could not be used for ECR33 RB25DET because NVCS oil pipe is running beneath the valve spring and it restricts the amount of the intake valve lift. Neither, could strengthen valve spring have been manufactured according to its construction.
Now, we developed RB25DET special intake valve retainer that enables corresponding to high lift camshaft by 10.25mm, by enlarging the amount of valve lift. Deceleration of the valve can be also secured by applying strengthen valve spring, which is required for the high lift camshaft and high rotation of the engine.
【Surging】
The Phenomenon which material of the valve spring resonance and causes the spring itself to vibrate violently.
【Jump】
The Phenomenon that the valve rallies to the cam surface instead of settled back. It happens when the valve cannot follow the camshaft rotation and lifted irregally.
【Bounce】
The Phenomenon that the valve is bouncing repeatedly from valve seat other than sticking to it when it is closing.
【Fatigue】
Breakage that occurs during the repeat operation of the spring. (The larger lift, the more possibilities to get fatigued)
【Sag】
The Phenomenon in which the load (free play) of a spring decreases while inuse. It is related to the maximum stress under operation and use time.

■ Super Lightweight Duralumin
The Duralumin alloy was chosen for it’s super light weight properties. So our product is made from 100% Duralumin.
■ SUPERIOR ACCURACY
Both the pulley and the gear sections were manufactured from special precision methods.
This helps secure the set position from the transmission drive to the timing belt.
■ SUPERIOR DURABILITY
Highly durable in contact areas with the timing belt has been greatly enhanced by giving the industry’s first product to have deep anodized colouring applied to the surface of the pulley.
It is suited for Drag Racing Cars that are well over 1000 HP and rev well past the 10,000 RPM mark. There are also no signs of the colour coming off.
■ UNIQUE DESIGN THAT STANDS OUT
Every bit of the pure Duralumin was processed with the deep anodized colour.
With the functional design.
■ USER FRIENDLY ADJUSTABLE SCALE
Great consideration was taken in making a simple and easy to follow adjustable scale for anyone to understand.
SLIDING ADJUSTER
The simple graph makes it easy to change the engines characteristics with the simple sliding adjustments of the Cam Gear. If the intake valve timing is advanced (i.e. 120° to 110°) then performance gains are achieved at low RPM. If the intake valve timing is retarded (i.e. 110° to 120°) then performance gains are achieved at high RPM. Camshafts with no dowel pin attached will require you to check the timing adjustments with a dial gauge and scale board.
EASY VALVE TIMING ADJUSTMENTS WITH PONCAM
The Poncams valve timing has been preset at 110°. This Valve Timing has been calculated as the best setting for both performance and drivability. You can adjust the engines performance by making adjustments with the cam Gear carefully. This easy adjustable system is a great advantage over other conventional designs.

The sealing performance has been improved considerably with the super grommet,to suit these engines and has been proven to brliver excellent relibility.
|
SUPER GROMMET TYPE
The dual sealing method of the bead structure & metal grommet, provides maximum sealing for the coolant, oil & gases around the bore circumference. |
■ Heat Conductivity & The Strength of Stainless Steel
Stainless steel was chosen to be the material of choice to make the Metal Gaskets with because of the heat conductivity efficiency of the stainless steel material to evenly distribute the heat and aid with cooling. This will greatly improve reliability and reduce the chances of problems.
The natural high tensile qualities of Stainless Steel greatly helps with increasing the joint ridged of the cylinder head with the cylinder block. This helps minimize the engine from warping when under severe stress loads that performance engines go through when running high power applications. The result is improved durability and added power gains.
■ ABOUT MARKING
All our metal head gaskets are laser marked with Models, Bores, Thickness, and TOMEI POWERED INC. company name.
Since there are similar/counterfeit goods on market, please make sure logos on Gasket. |
