The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Ignition guru advice needed- coils and wires

I'm resuming work on my fuel injection project and after checking the coils and wires with an ohm meter, one was well out of spec. I now plan to replace both coils and the plug wires.

Doing a bit of reading, the Accel supercoils (140403, 3 ohm) look to be a popular mod and I found a pair locally for a good price. The main headache looks to be the mounting, but since it has been done by others I can do it as well.

Here's my questions regarding them:
1. Do I reuse the OEM plug caps with this coil? Since one also spec'd far different (would not give a consistent reading) than the others (8K, 10K, 10K) I'm going to replace them as well since they are like $3 each. I want to reduce any EM/RF interference since I'm using a Microsquirt.

2. The NGK caps look to be sized for a 7mm wire. The Accel wires are 8.8mm. Any thoughts on a quality 7mm wire? Copper core? Suppression?

3. The OEM plug caps look to have been 10K. I see NGK domedstically only sells 5K caps. They also sell BR8ES plugs rated at 5K. Would this be a good combo?

The Microsquirt uses a hand made ignition module capable of passing up to 16 amps of current per coil. I have not found an ohm rating specification for using the Microsquirt, so I'm presuming the OEM 3 ohm unit would work.
 
Good quality copper core wire will do fine if you're fitting it with resistor caps. You don't need resistor plugs with resistor caps - one or the other will do.
