Default Advancing Timing On a NA

hello everyone i am abit new to be starting a thread but i have questions,
i was wondering what the effects are on the motor if you advance the timing, because i also use the car as a daily driver and need it to stay reliable (it has 148,xxx). i understand its not going to be any significant power increase, Advice will be greatly appreciated!

Assuming the car is stock. It would be easy enough to fill the car with premium, turn the CAS to advance timing to 14 degrees. Then decide for yourself if you feel enough power gain to justify spending $2 extra per tank of gas.

Turn it up to 11!

If you have the tools to do it yourself, and know what to do, then go for it. If you're paying someone to do it, don't bother.

*Go here:
https://www.miataturbo.net/meet-greet-40/
Read the first 3 threads, they are "stickies", meaning they come up a lot, so they are kept on top of the other threads so ppl will see them before asking common questions.

*Search to see if somebody has made a thread about what you want to know before you, it helps if you "search titles only" instead of whatever the other option is. Also, you can just google ****, obviously.

sorry about my noob-ness,
i have a 93 miata naturally aspriated 1.6l with a racing beat intake no other motor work. i was just wondering i should advance the timing to 14 degrees to possible pick up alittle more power. i have extra time and tools to advance it i am just debating whether its worth my effort and if it will compromise reliably. Thanks

From what I understand, advancing timing doesn't add power so much as move more power to lower on the powerband so you make more power at a lower RPM. Could be wrong though. Miata.net has a buch of stuff on timing.

I wouldn't even worry about it, unless you feel like dropping in 91\93 octane every fillup.

As long as you haven't hit the point where you no longer gain power, you will gain power everywhere because you are changing spark overall by how many degrees you advance or retard on the CAS.

Other way around IIRC. Advancing timing moves power up higher. On a track car, probably worth it, as you're constantly in high rpms. On a car driven on the street? Absolutely not worth it. Literally, not worth turning one bolt and then tightening it again.

Very simple.

You will need a paperclip, 12 mm wrench, and a timing light.

Open up the diagnostic port by your driver side of engine compartment. Each wire will be labled. You want to use the paperclip as a jumper wire. Just stick each end of the paperclip into the plug that is labled ground and ten. This will put the ecu in a mode that allows you to read the correct idle timing with the timing light.

Hook timing light to the number one spark plug, start motor and find out what the timing is at idle. It should be 10 degrees. There are two marks on the balancer one at 0 degrees and one at 10 degrees.

Loosen the CAS on the back of the camshaft and turn it until you get the desired timing. You will see the mark on the balancer move when you turn it. Retighted the CAS.

I did some testing with a stock Miata and changing the timing. I got the best elapsed time at the drag strip with the timing set at 17 degrees.
