The correct setting for the base ignition timing on a Toyota MR2 Turbo is 10 degrees before top dead center (10 BTDC). The computer-controlled ignition timing in the MR2 Turbo is relative to this base timing set by the alignment of the distributor. It’s important to note that the MR2 Turbo has a hybrid ignition system, with a mechanical distributor and single coil, while more modern cars have mostly moved on to a distributorless ignition system (DIS) and individual coils on each spark plug.
Please keep in mind that the information provided is based on the search results and may vary depending on the specific model and year of the Toyota MR2.

What should ignition timing be at idle?
At idle, typical initial timing figures are 4-10 degrees before top dead center (BTDC).
Can I adjust ignition timing?
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you’ll advance the timing by rotating the distributor counterclockwise, and vice versa.
What happens if ignition timing is off?
improper ignition timing will cause spark to happen at the incorrect time and your engine will barely run, if it can start at all. if your ignition timing is too advanced, the engine will start to ping/ detonate, which can cause rapid overheating of the cylinder and eventually can lead to pre-ignition.
How do I know if my ignition timing is bad?
A well-timed engine produces a harmonious hum. If you start hearing clanking, knocking, or pinging noises, your engine might be struggling to keep the beat. These sounds are the engine’s way of signaling that something is amiss with the timing of the combustion process.
What is the base timing on a Toyota MR2?
The correct setting for the base ignition timing on the MR2 Turbo is 10 degrees before top dead center (10° BTDC).
What happens if timing is slightly off?
improper ignition timing will cause spark to happen at the incorrect time and your engine will barely run, if it can start at all. if your ignition timing is too advanced, the engine will start to ping/ detonate, which can cause rapid overheating of the cylinder and eventually can lead to pre-ignition.
What is too much ignition timing?
If by “too much timing” you mean that the timing is too far advanced , in other words the spark occurs too long before the piston reaches it top dead centre then the engine will ping, idles too high and detonation will occur and it can burn a hole in a piston.
What is initial engine timing?
Initial timing (sometimes called base timing) refers to the position of the distributor that creates the crankshaft position where the spark plug fires at idle. This and all other timing specs refer to the position of the piston as it approaches the top of its stroke, called Top Dead Center (TDC).
How can I improve my ignition timing?
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you’ll advance the timing by rotating the distributor counterclockwise, and vice versa.
What is the correct ignition timing?
Most stock street engines call for 6 to 8 degrees of initial advance, but this is not set in stone. Engines with longer duration camshafts and other modifications often demand more initial timing. It’s not unusual to input 14 to perhaps 18 degrees of initial timing for engines with big cams.
