Both the 1.4 TSI EA111 and 1.8 TSI EA888.3 engine blocks provide a robust foundation for tuning, but pushing these power plants beyond factory limits requires fortified internal architecture. Strengthening the rotating assembly with Forged Pistons and Forged Connecting Rods provides the structural integrity necessary to withstand massive cylinder pressures. Securing these components safely demands Uprated Engine Bolts (ARP) alongside low-friction Performance Bearings for the conrod and mains. For engine builders optimising volumetric efficiency, Performance Camshafts alter valve timing for maximum top-end breathing. We also supply Misc Engine Parts covering essential seals and gaskets for comprehensive block rebuilds.
