Billet 2JZ-GTE Main Caps
The Titan Motorsports billet main caps are precision machined from high tensile billet steel. These billet caps are a must-have for any built 2JZ engine and will ensure that your powerplant stays together no matter how much power it makes.
The Titan Motorsports billet main caps are precision machined from high tensile billet steel. These main caps were developed out of necessity for the 2JZ race program are applicable in most street engines. With the increased boost levels seen in single and larger twin turbo setups, the factory crank pushes down on the caps often leading to stress fractures and cracks. The factory main caps were not designed for the forces required when doubling and tripling the factory horsepower and torque levels.
Titan Motorsports main caps will work with both the 2JZ-GTE engine found in the Supra turbo, as well as the 2JZ-GE engine found in non-turbocharged models. Please keep in mind that a line bore of the mains will need to be completed upon installation of these upgraded main caps. We recommend using brand new ARP Main studs and fresh bearings when installing the Titan Motorsports main caps.
