I would like to put a t-56 in my 1997 GT Convertible when I put the new motor in... How much would it cost to switch it all over... And isnt this something they could change in the ecu on a reflash... How much HP can the cobra 6 speed handle... If I could find one of them... I am looking for a setup to handle over 600 rwhp... turbo setup more than likely...
