After reading for awhile I believe I stand correct in saying that the KA transmission will not hold 500whp. That's what I want my KA-t to do. I read where some people are using the Z32 transmission to overcome this. Any KA-t owners pushing 450whp+ on stock transmission? If anyone is using the z32 transmission with their KA-t swap please post everything you did to make it work. Any info will help.
