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.
You're talking about 2 different kinds of timing here. On the drivers side of the engine is crankshaft/camshaft timing, and on the passenger side is IGNITION timing. To get the mark where you want it, loosen the distributor and rotate it until the timing is set correctly. Make sure you short the plug near the ECU (look at the label under your hood to find out what I mean).
