I was looking through my manual today and i happened upon "id locations" and it noted that the motor type stamping IE "K20A3" should be stamped on the block to the right of the intake manafold (looking into the engine bay from the front)
Now here is my delemia, there is some occidation on this spot, but what i can read is the Number "2". There is obviously some other letters before it, but occidation has rendered it unreadable at the moment.
I plan to take off my intake so that i can reach the stamping more easily. But for now it has my curiousity peaked, Could an A2 run off an A3 computer and thus feel and operate like an A3?
My car has come from shady origins, and as esmith13 aka Eric pointed out i do have an RSX intake manafold cover. My car also is notibly louder than other EP3s ive hung out with.
At a recent meet it was thought to be pully noise but removal and inspection of all pullys came up empty, im still curious.
