Awesome, this is exactly the kind of thing I was looking for. I love this forum- completely devoid of punk kids and chumps with more money than brains. Thanks again guys.

I need educated help.

I'm going to need intake piping for my 1st gen RX-7 13BT swap. The diameter of the intake pipe should be on the order of 2"-2.5" (haven't run the calcs yet, just guessing). I have not yet decided on the material I would like to use, but I am leaning toward thin-walled aluminum ...

EDIT: 05/09/06

Symptoms: Leading coil would not fire at all. I think that's because I fried the ignitor when I mistakingly grounded a wire I shouldn't have, then observed smoke arising from the condensor unit.

Trailing coil #1 would fire normally, however, I couldn't get the plugs to ...

Roger:

The coilpacks themselves were not grounded. Do they ground through the casing of the ignitor/coil unit?

I did all the necessary MS rotary changes, and all the Q14-Q16 resistor pullup hardware modifications.

I tried this for both the leading and trailing coil assemblies (using only one ...

Roger/all:

I went ahead and tried out the bench setup for the coils/ignitors, but don't seem to be getting a spark. I tried a 12V source from both a computer power supply (250W) and a lead/acid car battery with no results. I hooked up a spark plug to one of the two output ports on both the leading ...

As many of you may know, I'm doing a S4 13BT swap into an 85 RX-7 GS. I've managed to make just about everything work ignition-wise. The CAS signal conditions perfectly and pulls the 3 LEDs for coil events as it should ...
