Titan Motorsports Main Bearing Caps are precision machined from high strength steel. We developed these caps out of necessity for our 2JZ racing program and soon found that they were applicable to most street engines. With the increased levels of boost pressure seen in larger single and twin turbo setups, the factory crankshaft places stress on the caps, often leading to stress fractures and cracking. The factory main bearing caps were not designed for the forces required when doubling and tripling factory horsepower and torque levels. These caps are included in our short block and race engine packages and are now available separately for those building their own engines. Titan Motorsports Main Bearing Caps are compatible with both the 2JZ-GTE engine found in the Supra turbo, and the 2JZ-GE engine found in non-turbo models. Please note that a main bearing line bore will be required when installing these upgraded caps. We recommend using new ARP main studs and new bearings when installing the Titan Motorsports main caps. 2JZ 2000+ Stroker - 86.25mm Bore
