NISSAN RB28 KIT
 
The Ideal RB26.
Super Response & Big Torque
You'll experience dramatical changes in the RB26 with just the increase of 200cc in displacement. Superior response throughout, with just the slight changes in the throttle. Big torque with an overhwelming feeling of acceleration. Allows more room to grow with the ability to leverage the potential of larger turbos. Made from forged alloy for added strength, with the precision that you'd expect from TOMEI. Uncomparable with standard parts, and best value for money. Even to this day, the RB26 is one of the most popular sports engine to tune. True to it's form, the TOMEI RB28 KIT completes this true race engine.
 
Compatible with RB25 Engines!

KIT WITH BEARINGS INCLUDED
TOMEI Competition Bearing series
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.
  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.
