My very first one on my car took like three months! Now I can do these suckers in 3 weeks and that is including upgraded injectors and rails and extra goodies like boost controllers and gauges. I probably could be faster but I have a full time job. I went in blind on my first swap but if you have common sense and have this wonderful site you can do it. Just take your time and post up any problems you may have. Also try to get a front clip if possible the swaps where I got just the motor and trans and all other parts needed it looked like ray Charles took that shit out.
