Is there any articles made about building a shift kit for two speed gearbox or how to make it work manually. I am a bit interested after annoying shift problems with our Twin Turbo Y-block machine. How many horsepowers that kind of a tranny can handle when it is working properly or is it a waste of time to play with it?
