I use a Mendeola sequential gear box, I made the adapter plate. The SLC is made over by me by Detroit, most use a Porshe transaxle and LS engine package, I have messed with rotaries since my first new car was a RX 2. Got away from them in 80-90's then bougth this car and wanted something different, a 4 rotor was slightly to long without modifying the chassis, so the 3 rotor fit better, which I am glad I went with it. Haltech dash and ecu, just switch to the Elite 2500, still tuning it, which we will finish out in CA on the dyno with RRR tuning, Nelson. Its just a street car, been together for 2 years now, this will be the last year I take it apart for the winter, changing the body, fixing all the cracks and changing the nose a little, and redoing the wiring again, I dont think other then traction control I can add anymore and dont want to, so this winter one last time ill finish it up and make it nice on the inside. Its a blast to drive, I drive it all the time.
