I recently did the zc swap on my 4th gen si. I am POSITIVE that I matched up the crank pulley and cam gears to TDC when I changed the timing belt, but when I checked the car with a timing gun, it was off by about two inches. The car seems kinda sluggish and I was thinking that it would have more power, does anyone know if the timing could be the problem? Should I adjust it? Thanks.
