Hi, i wanted to to put a BW t5 or t56 in my z with a l28block. What needs to be done? How can i fit them to the block and is the t5 the same as the t56 tranny? Are the bell housings interchangable, or do i have to have a special one made for it? I want to have a 6 spd but dont want to spend a lot of money on adapting it to my car.
