its the same, they are all about the same
the tc trans is a WC trans
but still they are all like 20 years old and all about the same strength
some people run tens on stock T5s
some people blow them up with 88hp 2.3s
its all how you shift and take care of things, but eventually too much will just destroy it
search for your answers, if you can build a "400hp 289" then you should have enought knowledge
i understand more of what it takes to create that type of hp but its different when it comes to the drive train thats y if you look at all my posts there about gears and trans stuff other than the injectors witch i found my answer from a ford tech budy.
