Installation:

This Tomei Short Block is ready to install, however, professional installation by an experienced technician is highly recommended to ensure proper setup and functionality. Suitable for both street performance enthusiasts and professional racers alike.

All new cylinder blocks produced by new casting molds under the Nissan Heritage Program are used. You can select from two versions, N1 and standard version. There is a large difference in price between the N1 and the standard, but we recommend the standard for the general street use. For those who want to participate in drag races, full-scale races, and for those aiming for extreme power, we recommend the N1 which has even higher strength. Currently, it is difficult to obtain new blocks from Nissan Motor, but TOMEI has secured several units, so we are able to produce more, but please understand that the quantity is limited.

The crankshaft used is a forged billet full-counter crankshaft. The stroke is 77.7mm, which is a stroke increase of 4mm from the standard 73.7mm, delivering powerful torque. The counterweight has been changed from the standard 8 counter to a 12 counterweight with excellent balance ratio to achieve higher rotation and power, reducing the burden on the bearings and improving the durability of the engine.

The connecting rod is 119.5mm, which corresponds to the increased stroke compared to the standard 121.5mm, and is a forged H-beam design that achieves both lightness and strong durability with even stress distribution to the bearings. The connecting rod bolts used are L19 from the reliable American company ARP. Although they are more expensive than general ARP2000, they are extremely durable and have excellent reliability.

The piston is 87mm, which is 1mm larger than the standard 86mm, and the material is lightweight and strong A4032 forged aluminum alloy. The specified clearance of 0.05mm can be achieved by the material and the oval barrel design. It is the world’s best piston with excellent sealing performance, power retention, overwhelmingly low engine noise, less stress on piston rings, and outstanding durability.

The main studs and head studs are made by the trusted American company ARP. During machining work for engine boring and honing, work is performed after tightening the ARP studs to the specified torque on the torque plate and the crank caps. As a result, when the actual cylinder head is placed on the vehicle, the deformation of the cylinder block is extremely suppressed, and the appropriate piston and bearing clearance are ensured, providing maximum peace of mind. If these procedures are not made, there is a possibility of clearance error, with abnormal noise and decrease in engine durability.

Nismo bearings are used for both the main and connecting rod bearings and are carefully assembled by a veteran engine builder who has been building RB26 for over 30 years and are measured under a well-maintained environment with optimal temperature control giving it an outstanding sense of reliability.
