What fuel management are you using?

Hondata, Uberdata, and most other programmable units will take care of ignition timing for you, making the capabilities of the SCI (a 6-series ignition) almost useless. On top of that, capacitive discharge is NOT ideal for turbo situations. Turbo engines really want a long duration spark to ensure ignition.

The "upgrade" most think of is simply an improved ignition coil. On top of that, low resistance wire and a proper spark gap will take car of that thick mixture. On some cars, it is nessessary to build a "flyback" board to avoid frying the ECU with wildly powerful ignition systems, but I have never heard of a Honda guy using one.

damn thanks for the input, so who makes an aftermarket ignition coil for h22's? and which type of wire is low resistance?

I have seen OEM grade wires run some pretty high power set-ups. I think that you would be best to just re-build the stock ignition system.

im running a blaster ss coil with a SCI ignition for about 4 years and I didnt have any problem but when I bought the kit I didnt know that the stock ignition was fine...

Should I just run the blaster coil ? and sell my SCI ? I put down 300whp on my street tune and I will be doing a little more ( around 350whp on my race tune ) this summer on my D16Z6...

I someone could help me...

As stated above, if you're using any kind of EMS, you don't need the functions of the SCI. The 6A is the base model, and is really all you need to run the external coil [Blaster SS]. If you really want to say goodbye to the stock ignition, you'll need to bypass the ICM, or ignitor.

The 6A and the SCI are the same box except the SCI box is a little better for higher rpms, its silver, it says SCI on it, and it costs more..

So if you had to choose between the box or the external coil, which would be the best to put on first?

You can upgrade to an external coil which will make the ignition system alot stronger.. After that then upgrade to an ignition box.. I used the BlasterSS coil for a long time and it always worked great..

and why does everyone get the ss over the hvc?
