This is aimed to the tranny guys who make 9x11 converters. Can you make one for any car? Namely a 93.5-98 Supra Twin Turbo (Mk IV)? Or is this a project that you need to make a whole buttload of parts to keep the costs down? How much for just one, even though others would also want one. Just asking since I do not own a Mk IV, but plan to. ERIC.
