Phil, I have two of those trannys saved up to use with my RB. If I swap out the front Z31 bell to the rb25 bell, that makes up the same trans we use for our rb swaps (rb25det RWD trans). I was thinking, if I could just get these two tranny's machined, and a adaptor made to the rb bolt pattern, like you did for the L6, I wouldn't need to source a rb donor bell to mate to the Z31 trans...
Do you think that place would make up those alum adaptor plates to the rb bolt pattern?
BTW, those tranny's can handle mucho power, compared to anything you've been using!
Great Video!!
