Tomei has made an option to include their Competition Bearing Series product with our kits. All the engine internals are brought to static temperature (20 degrees Celcius) and blueprinted with 0.040~0.060mm clearance bearings.
This eliminates the measuring and blueprinting process for the customer, so the kit can be installed with less hassle.

Although the stock product is not metal, yet the sealing performance is limited due to the grommet type 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. |
The bead top pry is made of durable but flexible SUS301.
High heat radiation character of SUS301 helps transferring heat of the head and the block to coolant efficiently and prevents heat spots which causes gasket blow.
SUS301 is also known for its tensile strength and it helps the beads to keep sealing the head and cylinder which repeat heat expansion and shrink all the time. This structural strength also improves torsional rigidity of the whole engine by improving coupling rigidity of the head and the block.
![]() ![]() |
The gas sealing characteristics will improve with the raised rib, but the sealing characteristics of the neighbouring water and oil channels are equally reduced. Therefore when pushing for power gains, these areas are weak points that can allow leakages.The TOMEI design focuses on all areas to provide the maximum seal with the use of the super grommet design. By using the rib height to ensure an equal overall high surface pressure seal, where it is needed the most. |
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. |

REINFORCED BOLT
In order to secure the performance required of head gaskets, such as cooling, rigidity, and sealing, it is necessary to strengthen combination of a cylinder head and a cylinder block. However, in combination with a common bolt and nut, no matter what strengthen bolt it may used, bolting power concentrates on from third mountains to the 1st mountain of the screw, and the total bolting power cannot be increased beyond a certain value. Moreover, excessive stress is concentrated and may damage the bolt. Stud bolt, on the other hand, is applied dynamic design to its threading so that the bolting force is dispersed to all the screw threads and mighty bolting power is generated.

●BOLT STRETCH LIMITS
Bolts and screws in general will stretch when placed under stressful conditions. The stock bolts will tend not to return perfectly to its original shape once stretched due to the manufacturing methods used for the original purpose of the bolt design. Tuned engines will go through many procedures which require the bolts to be reused during every step. When having a dummy head installed and getting a bore and hone, when checking for bearing clearances and so on. So when the bolts are removed and torque up repeatedly bolt stretch management will then become difficult to manage the and retain the strict clearances required. The TOMEI Stud bolts are the best choice for high performance precision engines which require the fixed elastic range of the bolt set for repeated use and to maintain performance. The TOMEI Bolts will keep your engine together when needed most.
●ROTATING SURFACE HEAT TREATMENT
Rotation processing is the method of Rotating Die and Work Hardening the raw core of the bolt is placed on the cradle between the two rotating die with pressure applied from both sides. The metallic crystals within the bolts are then deformed at a microscopic scale, and then interacted with one another to make up a strengthened bolt that carries increased yield strength. The chromoly steel of the Tomei strengthened bolt is first heat treated and rolled on the rotating die, increasing impact resistance, surface strength, and longevity. These standards add up for the highest quality product available.
●ANGLE TORQUE BOLT TIGHTENING METHOD
An engine cannot be properly built without the use of the angle torque method when tightening certain bolts. It is necessary to utilize a special angle gauge when tightening strengthened studs and connecting rod bolts. Applying torque to the bolts without this specialized tool can lead to immediate or eventual catastrophic failure of the engine assembly.
Lack of bolting force | Excessive bolting force | |
---|---|---|
Head bolt | ・Leaking gas, water, oil caused by lack of the sealing pressure ・The further fall of bolting force, loosening, and engine breakage. |
・ Leaking gas, water, and oil from excessive bolting or failure of sealing pressure. ・Breakage of the cylinder from distortion. ・Poor piston clearance caused by cylinder distortion. |
Crank bearing cap bolt Conrod bearing cap bolt |
・Worn out of the engine by bad bearing assembly. ・Noise by too much clearance of bearing. ・The further fall of bolting force, loosening, and engine breakage. |
・Worn out of the engine by bad bearing assembly. ・Worn out of the engine by poor clearance of the bearing. |
●TORQUE NUMBERS CANNOT BE TRUSTED
Engine components that require precision accuracy when tightening its bolts cannot be trusted with basic torque figures. This is due to 80~90% of the friction is lost on the surface of the thread and the seat when tightened, with the correct figure being at 10~20% of the torque applied. The surface of the thread and the seat depends on the roughness of each surface and the lubrication state, so that no matter how accurate the torque specs are specified it cannot be trusted.

OIL LUBRICATION
The SR20 engine’s factory oil block tends to fail due to the weak oil filter sensor screw which often breaks. We here at TOMEI had found the problem during professional racing over a decade ago, so we designed & produced this upgrade oil block which solved the problem.
We had later discountinued this product after the end for the N2 series race but due to popular demand we had to bring it back into production with a new revived design. Now being lighter than before with ports for oil temperature and oil pressure sensors. The failure in the oil block can lead to engine failure so this is an absolute must have upgrade to protect your investment. Especially with vehicles running a sandwich block or similar the oil cooler can fail at times so you have to take added precautions.

The 4G63 Expreme manifold is one of a kind in design. Starting off with its smooth curves, the Expreme exhaust manifold has excellent flow characteristics. The tubing used has a diameter of 45 and is considered to be the best size when achieving for maximum torque. The material used for the piping and flange is aircraft quality SUS304 stainless steel. This material is very durable against corrosion and other harmful elements. Though in time, a light discoloration may be present, it is to be noted that this material will not deteriate. The process used to assemble this manifold together is know as the lost wax method and is very advanced in the sense that it helps promote the strength and long lasting structural integrity. Along side this well developed manifold is a manifold accessory known as a heat shield. This one off in design heat shielding device is also made from durable SUS304 stainless steel. When attached, to the exhaust manifold, this Expreme heat shield will help promote cooler under hood temperatures, thus other peripheral engine devises will have cooler and longer lasting run times.
