ok, if you want a rotary, do what i'm doing with my 91 rx7. S5 (89 - 91 model) 13B turbo block, streetported. remove the turbo and all of its components, then take out the rotors. install n/a rotors (9.7:1 compression, compared to 9:1 compression for turbo model) and counterweights, new injectors, ecu, and harness. once you get the air/fuel ratio right, you will easily have around 200whp. bolt it to a turbo model 5 speed tranny, and use the stock zuki t-case. i was planning on doing this exact swap into my 89 kick, but its too much work for me. plus, my kick is my daily driver, and i just need to keep it running until i finish my rx7.
