03 is the ap1 i believe

the ap2 is when the upped the displacement to 2.2l and lowered the redline to 8k which raise the torque for the stupid americans

japan still uses the 2.0 engine from the ap1 as far as i know....

well mtber...i was offered 16k on hondatech and would honestly laugh if someone offered me 10k. nada value is 11.8 STOCK...

and im not even going to ask why you think hondata is unneccesary because that is a can of worms i dont want to open and have seen the threads debating the different engine managements...
