ACL Race main bearings for Lotus 2ZZ-GE

ACL Race Series trimetal main bearings are designed for higher RPM conditions. The combination of construction, metallurgy and engineering provides improved fatigue properties and reliable bearing retention in the housing.

The set includes ACL Race Series main bearings with improved heat transfer, increased eccentricity to compensate for bore distortion at high RPM and tight, consistent wall tolerances.

• High-strength overlay plate with reduced thickness
• Increased crush for improved bearing retention
• Elimination of flash plating on the back for improved heat transfer and grip in the housing
• 3/4-grooved main bearings to optimize load-carrying surface area and oil flow
• Increased eccentricity to assist in the formation of hydrodynamic oil films
• Tight, consistent wall tolerances

Suitable for: Lotus 2-Eleven I (ROADSTER/SERIES3), Lotus Elise II (SERIE/2), Lotus Exige II (COUPE/SCC), Toyota Celica VII (T23), Toyota Corolla IX (E12).

Engines: 2ZZ-GE. Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
