Holden 304 wiring storm

[shrug]

I’ve never touched a v8 with this firing order so checking I wire the wasted setup ls coils correct, with the firing order being 1,2,7,8,4,5,6,3 I wire as?

 

drive 1, 1-4 

drive 2, 2-5

drive 3, 7-6

drive 4, 8-3

 

also with injectors do I use the normal v8 pairing of injectors like a 1uz or the likes to run sequential injection or just use the same pairing as above? 

Sorry v8’s aren’t really my forte but doing this one as a favour so looking for a little guidance on the pairing since it’s a older g4+ storm with 4 drives. 

 

Thanks all.

Your coil pairs are correct.  The firing order doesn’t lend itself well to semi sequential so I would use multipoint group, wire 2 injectors on each side to an even numbered driver and two on each side to an odd driver.

So would you suggest 

 

inj 1, 1-5

inj 2, 2-6

inj 3, 7-3

inj 4, 8-4 

 

 

appreciate your input, thank you.

I dont think so.  Assuming this engine has cyl 1,3,5,7 down one side and 2,4,6,8 down the other then your proposed pairs would end up with all of one side connected to even drives and all of the other side connected to odd drives.  This would mean all 4 injectors on one side would switch on/off together and you will end up with large pressure pulsations in the rail.

Something like this would be better:

Inj1 = 1&3

Inj2 = 5&7

Inj3 = 2&4

Inj4 = 6&8

I’ll go with that, much appreciate your help.

4-6 cylinders are my thing so v8’s are new ground to be wiring. 

 

Thought it was better to ask and do it once than change it assuming. 

 

Thank you again.
