Brand: Tomei
Product: Forged Full-Counter Crankshaft 4G63-23
Part Num: 121040

Crankshaft is the parts that change vertical movement of a piston into rotational movement. It is suffered from explosion load and inertia power, and the load by bend vibration or torsion vibration.

- Full-counter weighted camshaft:
By preparing counter weight on every cylinder, making inertia power balance so that bent of the crankshaft is suppressed and vibration and friction is reduced, while the reliability of bearing is raised. (Applied to all engine model excluding CA)

- 2 route lubrication:
Two-route oil supply from two journals secures crankpin an enough amount of oil supply. Moreover, X shape oil passage enables supplying oil using the centrifugal force of a crankshaft; reliability of the oil supply at high RPM is improved. Furthermore, and resistance of oil flow is reduced by giving a modification on oil hole exit. (Applied to all engine model excluding CA)

- Balance rate:
Counter weight has its original shape that is designed with theoretical analysis, to secure the proper rate of balance (rate which negates the inertia power of a reciprocating movement) while reducing its weight.

- Edge shape designed with hydrodynamics:
At high RPM, counterweight rotates at more than 200km/h* inside the crankcase through the oil and air. Tomei designed the edge shape of the counterweight hydro-dynamically sharp so that less resistance will occur even at high rotation. (Applied other than CA)
*: If the radius of crank counter weight is 65mm, its circumference is 408mm = 0.4meter. When the engine is running at 8500RPM, crank rotates 141.7 turns per second which is translated in 56.7m/s = 204.1km/h of peripheral speed.

- Forged SCM435 metal:
Tomei selected chrome moly steel as a material (STD: regular steel) and forge it in the mold to improve the organization of crystal. As a result, metal flow is formed along with the shape of crankshaft that gives 2times more strength to the metal than before. (Applied to SR engine)

- WPC finish to the pulley journal:
WPC finish* prevents pulley and pulley holder to be worn and keeps good maintenance of the engine. (Applied to RB engines)
*: WPC finish is shooting micro ceramic spheres (45mm diameter) to the surface of the metal at 200m/s of speed.

Special Features:
- Designed for Torque and Drivability.
- 100.0mm Stroke
- Full Counter Weight Type
- Nitride Surface Treatment:
-- Nitride treatment is used for high perforamnce and high power applications for increased engine durability and longevity.
-- Low Friction: Minimises Metal Distortion.
-- High Precision: Minimises dimensional changes during use.
-- For High Output Components: Core strength not comprimised.
-- High Strength: Abrasions & seizure resistance is increased.
- Crankshaft Marking:
-- Each Crank comes with a logo and spec marking The marking shows the genuine Tomei product.

RHDJapan Store Reviews

very good pressure cap the only parts that i will use

Built quality is amazing as always, cusco reputation live up to it self, most of my suspension and braces are cusco and never dissapoint.. RHD Japan.. no need to say anymore, always awesome, loyal customer for 3 years and never a disappointment .. best place to get some rare Japanese made parts.. 99% of the time also with best pricing .

Awesome built quality, much better then the OEM STI ones which looks ... very inadequate.. RHD Japan awesome as always with quick response on item inquiries .. been getting car parts from these guys for 3 years and never dissapointed

I ordered the RS-Takagi side steps to replace the worn and deformed OEM side skirts on my 91 R32 GTR. The fitment was nearly perfect and only required minimal work to get them to look perfect. Once installed they are very solid which has led to the requirement that I must tell my passengers not to step on them, haha.

Yet another great product from kts and super fast delivery from rhd to the uk
