I've been searching for a solution for my problem. I am almost done doing a Ver4 STI swap to my GC. I am using a WRX ecu and have the harness already merged. My only issue is the cam trigger wheel. Is there an easy solution to this? WRX cams don't fit in the v4 heads and the gear and triggers are different. Is there a gear that will bolt up to the v4 cams with the triggers in the correct position? I am about to just say screw it and throw WRX heads on it, but i thought I would reach out and see what you guys say. I really wasn't planning on buying bolts and gaskets.
