Tomei COMPETITION BEARING for Nissan RB26/RB25

Durability & Reliability, The Answer for All Professionals!!

When tuning engines for higher power output and high RPM the bearings are subjected to extreme load conditions. These harsh conditions require the bearings to be able to cope with excessive loads and stress conditions. The TOMEI Competition Bearing series are designed for fatigue resistance, durability, effective lubrication and resistance to scoring. Designed for use on engines that will be outputting 1,000 HP and at over 10,000RPM. These advanced designed bearings are suitable for the serious professionals in mind whom need results. We also have 3 grades available on all engine applications.

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.

■ 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.


TECHNICAL INFOMATION

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.
Terminology
【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.

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.

TIPS

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.

■ 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.

Tomei ROCKER ARM STOPPER For SR20DET

Tomei ROCKER ARM STOPPER For SR20DET

When over revving or miss-shifting the SR engine whilst at 7000 RPM and over during circuit runs or drag racing can sometimes cause the tappet side of the rocker arm to jump and rocker arm to come off. This Rocker Arm Stopper is a simple cost effective part which holds the lash adjuster side of Rocker Arm in place with a fixed clearance that prevents the rocker arm from disastrous results when the arm jumps and so will protect your engine from terminal damage.

Tomei OVERSIZED OIL PAN for SR20

Tomei OVERSIZED OIL PAN for SR20

The oil in the sump will forced to the side walls of the oil pan during side G force loads during Drifting, Time Attack and Drag Racing use. These problems can escalate to serious oil starvation in the engine when there is inadequate oil in the sump for the oil pickup which can lead to engine failure.
This oil pan increases the capacity with an extra 600cc without compromising the ground clearance so really low cars will not have any issues. With the internal design featuring 2 swing back doors which further aid with holding the oil in the center of the pan for the oil pickup point.

FEATURE / SPEC

BORN & BRED FROM AN N2 RACE SPEC SILVIA.

The Silvia N2 race car was powered by a Tomei 270HP NA engine which back in the day was named the “Ultimate SR20 Race Engine”.
The regulations prevented the use of a dry sump setup so under the extreme track conditions the standard wet sump setup had to be re-designed to cope with the requirements that the race engine needed. Road clearance was taken into account for the ultra low ride height of the car and even after all these years this oil pan is still popular with SR20 users.

■ Designed for G-Forces


The 2 plates with the one way rubber valve made in the pan are specifically designed to keep the pickup submerged in oil at all times.

The stock oil pan was not designed for the serious performance so when the oil moves away from the pickup and then if any air gets sucked into the lines. Then that brief moment when no oil is supplied to the vital areas, metal contact is made and unwanted metal friction in sensitive areas which then leads to engine failure.


■ High Strength & Accurate Welds,Maintain Road Clearance


Our highly accurate welding on pan with our famous strict standards to ensure no oil leaks with the high quality welds and as a direct bolt on product as you would expect.
Unlike the cast type oil pans this is made with stronger materials which will take a good hit and not crack like a cast based one would. Stronger and safer for your engine.

■ Optimum Oil Level



The extra 600cc was decided as it was found to be the best amount to suit for the required performance to suit the needs of the N2 race cars in the past. Still to this day this is still the best amount for Time Attack, Circuit use, Drift and Drag Racing. Designed to maintain an adequate level of oil for the pickup to supply the engine without compromising performance with unwanted friction on the spinning crankshaft or extra weight.

【OIL SPLASHING & WINDAGE】
The combination of the spinning crankshaft and G-forces will cause cavitations (oil bubbles) at higher engine speeds which leads to erratic oil pressures and reduced oil supply to the engine.

WIDE MOUTH & 3 INCH PIPE


The port shape to the turbo has been optimized for maximum flow. The inner parts are all smooth without any steps for improved gas flow. The front pipe side has been enlarged to 3 inches (76.3mm). This will suit those larger front pipes to achieve more power gains.
sr_outlet_hikaku03.jpg sr_outlet_hikaku04.jpg
 
HIGH STRENGTH / PRECISION FLANGE

The flange was entirely made with the precision lost wax process. With sufficient thickness to cope with the harsh vibrations and high heat temperature. The front pipe side is molded without compromising the volume and to ensure a smooth exhaust flow.
sr_outlet_hikaku05.jpg sr_outlet_hikaku06.jpg
 
DESIGN FEATURES


We have incorprated a dimple in the pipe where the bolt for the flange is located. To allow ease of access to both bolts & nuts to allow a quick, trouble free bolt on installation.
The capacity was maximized whilst ensuring the clearances with the transmission housing.
