TOMEI SR22G Complete Shortblock Assembly - Nissan SR20DET

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei’s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei’s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei’s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.


Tomei's new Complete Engine Series Product Range are built from completely new base Nissan OEM engine blocks at their facility in Japan. Engines are always in stock with minimal delivery time, don’t waste precious time with your hectic race schedules!

The all new TOMEI Complete Engine Short Block has been revised, tradition and precision have been refined to an all new level. TOMEI Complete Engine Short Blocks Include:

Forged Pistons
From the combustion chamber to the cylinder, a piston works inside the core of the engine assembly where the energy of the explosion is converted into rotational movement. The piston suffers the most abuse out off all the components inside an engine, with standing such factors as the force from constant amounts of massive energy and severe fluctuation in temperatures.

Forged H-Bean Connecting Rods
The connecting rods role is to transfer the compressed pressure that the piston receives to the crankshaft. When the connecting rods inertial weight and balance then plays a major factor in the smoothness of the engines rotation assembly and durability at high RPM. The weight factor it self will dramatically change the engines characteristics.

Forged Crank Shaft
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.

Main Studs
When applying fastener load to any type of bolt, it typically applies the most stress to the first three threads. Tome Powered head studs are designed to distribute this load throughout the entire engaged thread of the stud, for the maximum holding capability.

Competition Bearings
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.

In addition to engine components listed, TOMEI Short Blocks also include

• Serial Plate – A special TOMEI Serial number is linked with the engine and the manual provided.
• Spec Card – Clearly specifies the main parts and specs for reference on your future rebuilds.
• Product Manual – Explanation book detailing the parts & build process to give you the inside view of the technical power of TOMEI.
• Emblem – A TOMEI emblem is included for displaying that your car is fitted with a TOMEI short block.
