The same one you see is the one used for the SR, KA and a few more nissan motors. The only reason why I added the fact that i had to re-angle because if you look at the return portion of the regulator, you'll see why. So yes freaks, it will fit your POS CA motors:D. They don't have a listing for a CA18, so that's why I said I'm one from the SR
