take it you dont now much about the 4g63t evo engine, the only evo,s that suffer crankwalk or evo,s from 1 to 4.. crankwalk was due to the main bearing mitsubishi re designed them from the 5 upward, you cant do anything about it if you have evo 1 to 3 , but if you have a evo 4 you can put a 5 block in and take advantige of the new bearings



this is my 3 block i built up after crankwalk the middle bearing is the problem i put full race bearings in to help...



the problem bearing, evo 3 also suffer ring land failure, so i put evo 9 pistons in
