You will need the later, bigger crank from AE92 and newer models. Some AE92 with T-Vis will have the bigger crank and all of the small port AE92s have the bigger crank.

Those rods are for the bigger crank also as the 45mm big end bore when fitted with bearings will suit the 42mm crank journal. Did your country get the AE92 Corolla?

Do you have access to a machinist?

The inside of the small end of the connecting rod can be enlarged from 18mm to 20mm.

As long as rpm levels stay under 7500 there should be no problem. rpm levels exceeding 7500 may be a problem

actually it is the reverse. smallport is newer, uses larger rod journal crankshaft. The largeport is older, and it uses 40mm rod journals
