1ZZ ZZW30 MR-S
Special Honing
The cylinder block operates under both mechanical and heat stresses. TODA's special honing process heats the block and along with the use a dummy head recreates the forces found in the block under normal operating conditions. This process helps to improve piston to bore sealing giving you more power.
