You dont need custom pistons (wrist pin hight) unless you are putting a 4g64 crank in a 2.0L block which would make it a 2.3L. Rods, wrist pin hight and bearings are all the same between the 4g63 and 4g64 motors. (6 bolt = 6 bolt and 7 bolt = 7 bolt.. Duh)
The 4g64 has a deck hight 6mm higher than a 4g63, there for since the 4g64 crank has a stroke 12mm larger, 6mm TDC and 6mm BDC... The pistons and rods are the same specs except for the cylinder size making the pistons 1.5mm larger in the 4g64. 85mm bore in the 4g63 and 86.5mm bore in the 4g64. Just some tech info.
Some of you know this but for others who dont...
