Correct Firing Order for an 88 turbo
 
I know the firing order are the same for a turbo and a n/a but i need some info.

153624

I Know that because the 1&6, 2&5, and 3&4 pistons move with each other up and down.
Ever notice that when seeing a block?

That means that:
1 & 6 have to be 3 after each other.
2 & 5 have to be 3 after each other.
3 & 4 have to be 3 after each other.

Also in the equation: No cylider ever fires after the one positioned next to it.

You can also get the firing order by looking at your cams and see what order the cams have their lobes stick out.

Every inline six cylinder I have ever seen has been 153624.

153624 = Combustion Sequence/Firing Order

Do you actually think that #6 could fire after #1?
That is impossible by looking at the crank!
The crank would need to spin a whole 360 for the next fire/ignition if that were true, and that only happens with twins (2 cylinders), if we are discussing four stroke engines (meaning 360 degrees of crank rotation for each ignition).

Here is a picture of the crank I am selling, notice that the 1&6, 2&5, and 3&4 crank pins will move the pistons up and down at the same time, in synchonozation, although the actuall firing will be 360 degrees behind each other, or 3 each other as I have already stated in the order.

What you see on your coil packs is not the firing order in terms of combustion, that is a false assumption if you think that the coil packs denote when combustion happens!

If you don't take my word for it, I guess I will need to look it up of you :p
And here it is from http://www.cygnusx1.net/supra/librar.../em/EM_03.html :

You may be thinking of some other term, but it is generally accepted that firing order denotes the sequence that combustion occurs in the cylinders.

i got that firing order from so many sources but yesterday after the head was installed it ran so smoothly no shakes nothing. it purred like a kitten. with the firing order being 1-6-3-4-2-5 thats how the wires were when i got the car.

suprra_girl 04-03-2006 12:23 PM

yea, what happens with the wires isn't what happens with the cps

you have the coil wires perfectly fine
just the actual boom isn't at the time that the numbers are on the coils :)
