Please tell me about ignition timing

[novocaine]

yep i know about the possible consequences, we also only have 95 octane fuel

There are a number of 20V's in sa running advanced timing and they do run really well. The most i've heard of with the stock set up is 16.

South Africa was lucky enough to get quite a number of toyota corollas with the 20V blacktop motor, but its only recently that guys have started to modify them and actually find out about these little things increase performance.

For instance the 63mm exhaust... The local exhaust guys thought it was too big but in fact it makes the car run quite a bit better.

I was trying to understand why the advanced timing would work, and to make sense of all the talk of the advanced curve by a certain guy, but i think its cleared up for the most part. Thanks again for the information.
