This is one of the many items that we are redesigning and manufacturing to reinforce the internals of the engine. With a full aluminum block construction, we were concerned about the extra stress forced induction would create. We designed cast iron cylinder sleeves to reinforce the cylinder walls. The block is going to be machined to remove material which will allow these sleeves to be pressed inside.
Although our power goals are relatively conservative, we decided to reengineer all engine internals for increased strength for long term durability. The connecting rod beam was changed to a forged 4330 H-beam design. Two holes were machined in the rod end for pin oiling. Hardware was upgraded to a 285,000 ksi rated fastener.
