Advancing and Retarding Cam Timing..
I already know alot about it so theres no need to explain what it is or what the basic functions are...ive read up on a few sites (yet none to fit accords) that changing the timing can me done without a timing light. a few civic sites have said it and some other forums... well yeah since timing can be done without the timing light..the question is can it be done on our cars and if so what is the step process... F23A1 engine...
im trying to retard it for better high RPM performance...
and if the timing is done...will the ignition timing need to be set as well?

Physically, you just slip the timing belt off by a notch or 2. Better yet, get an adjustable camshaft sprocket because 1 notch might be too much.
On 1998 & later, the spark timing is controlled by a sensor down at the crankshaft sprocket. Your distributor doesn't even have slots for timing adjustment. But now your crank & distributor timing sensors will be a bit out-of-phase. I don't know whether the ECU will notice & set off warnings.

and ur sayin i cant adjust the ignition timing correct? bcuz of no slots for adjustment...

You can't adjust the spark timing, not just because the distributor has no slots, but really because the spark timing is mostly controlled by the TDC sensor down at the crankshaft.
If you were to enlarge the distributor mounting holes into slots, that won't move the spark timing.

oh alright...so with the timing belt...slip it like back or forth on the teeth a notch?....(hypothetically speakin if i dont get the adjustable camshaft sprocket)

I agree with JimBlake, i dont think youll like the results. your higher RPM's might be a little better but youll lose all bottom end torque. Youll almost have a power band, very little power until a certain RPM range then it takes off.
(I did something kinda like that with my 05 mustang gt. had no power until 3000 RPM and in town i was getting like 6 haha)
