My cousin, brother and I were having a conversation about cars and my cousin popped this modification up. Knife edging crankshafts. I never heard of it until he was explaining it to me. I was researching on the Pros and Cons about doing this modification in the near future to my engine but I didnt find any hard facts on how it performs on 4G63 engines. I'm planning to drive it DD with this modification, so I will be doing more of a "street" knife edge instead of the "race" knife edge some time in the near future. I found a site here about these cranks for our cars (1G,2G,EVO) and now I am planning to do it to my spare engine in the near future. The question I am looking to get answered is how realiable is this modification on a DD car? I know the application varies, but this kind of mod isn't bad for a rebuild.
