i just bought a 92 civic sedan dx. i bought this with the idea to swap in the d15z1 (vx) engine into it along with its tranny for the gas milage. from talking to people about this and doin research, i believe it should just be a direct swap in as long as i use the vx engine, tranny, ecu, wiring harness, and 02 sensor. if anyone has done this swap before or has any information or tips for me i would appreciate it. i want to make sure that with all of this, it will be a direct swap. also, does anyone know the civic vx tranny code?
