For Michele’s engine, we decided to run King Bearings. As we get more and greater experiences with them under very demanding conditions, we continue to use King XP bearings in our highest stressed builds.
We have been pulling down some of our race engines to find that the bearings look nearly brand new with XP bearings after sometimes more than a season of use. With this kind of history, we decided to use King XP bearings again. Pictured here are the rod bearings.
We also used King XP bearings for the main bearings. King’s XP bearings use their proprietary pMax-Black material. This is a tri-metal bearing with steel, a very high capacity copper based intermediate layer and a softer lead-based overlay that contains 5% copper and undergoes a proprietary hardening process for industry-leading load capacity.
In addition, the King mains have elliptical oil holes, undercut oil grooves for the maximum bearing area, a very tight crush for optimal heat transfer and solid retention, and an eccentric ID to help form and maintain a hydrodynamic oil film easier.
The XP main thrust bearings are swedged to the main bearing shells. The XP bearings are treated with King’s pMaxKote™.
The black colored coating is a new approach to coated bearings. The pMaxKote™ coating is a non-sacrificial layer that has a proven superior wear resistance and protection against metal-to-metal contact. The coating gives enhanced wear and oil cavitation resistance due to lower surface drag with superior anti-seizure properties.
We sourced brand new genuine Toyota seals for the engine. OEM is almost always the best quality when it comes to these sort of parts.
We also sourced brand new genuine Toyota OEM cam timing chains since we didn’t know the core engine’s history.
