TITAN MOTORSPORTS 2JZ BILLET MAIN CAPS FOR TOYTA SUPRA MK4 JZA80

-

Titan Motorsports billet main caps are precision machined from high strength billet steel. We developed these main caps out of necessity for our 2JZ racing program and soon found them to be applicable in most street engines. With the increased levels of boost on single and larger twin turbo setups, the factory crank presses on the caps, often resulting in stress cracks and tears. The factory main caps were not designed for the forces required when doubling and tripling the factory horsepower and torque. Included in our short block and race engine packages, these caps are now available separately for those building their own engines. Titan Motorsports main caps work with both the 2JZ-GTE engine on the Supra-Turbo and the 2JZ-GE engine on the non-turbocharged models. Please note that installing these updated main caps requires a line hole of the mesh to be completed. We recommend using brand new ARP main bolts and fresh bearings when installing the Titan Motorsports main caps.
