Second Gear is a weak link

[Spaz]

I wouldn't know about a supercharged K24 but I know a turbo'd K20 has 4th gear as the weak link Great pictures though. How are you rebuilding it?

Funny I'm in the process of rebuilding a friends turbo transmission that blew out fourth gear! lol

I've cryo treated and that still didn't work. I've basically just given up hope and I just keep buying new main shafts. They aren't that expensive. But I am saving up for PPGs
