5 speed stock gear box
 

Hi Everyone doeas any body know that can I install a non turbo supras gear box in twin turbo or not if yes what are the precaution i have to take?

Well... Of Course you can... The major precaution your going to have to take is Do you know what your doing! Don't try to do anything you've never done or watched someone do. Thats a horrible Idea! You could mess something up and do more damage then you think. If anything have a friend that knows what hes doing or a professional. If you know how to though I guess you could give it hell but i advise you not to do it if you don't know what you're doing.

You could, but why would you want to? The non turbo 5 speed is a w58 and the turbo is an R154. The R154 is a superior transmission and will handle a tone more HP than the W58.

I would recommend against such a swap
