No reason to do with the 8 speed you have have to remember that the new 8 speed trans are more for economy then performance. Not to mention the aftermarket is just now getting the NAG1 to work in a swap. and that Trans has been out for 8+ years. As of right now the 8 speed can not even be tuned in the new cars yet so until that can happen I do not even think it is worth investing any time or money to see if it can be done.
