Does anyone run the MSD 2 step with nitrous?
I ran it with my turbo car and it worked great.
If either of you plan on using a 2 step though you'll need to wire an interrupt relay for your nitrous that either works off the clutch pedal or the transbrake to interrupt the nitrous/fuel solenoid relay.

I used it with a 6 speed setup. Use the blue wire from the MSD and the interrupt from the nitrous controller (some have them built in I used the FJO in my app), splice them together on the top side of the clutch switch, and then run the bottom terminal to a ground, when you push in the clutch, the circuit is grounded and the msd is activated, nitrous not activated, soon as you let it out, the msd deactivates and the nitrous now functions. Really simple. Transbrake is similar but you would have to use a relays instead. Put the ground (PIN 85) of the relay for the trans brake to one side of the button, and then to a good ground. On the output of the relay (PIN 87), splice the white wire of the msd and the transbrake positive together. On pin 87A will be power for the controller or window switch. Essentially, when the button is not pushed in, power goes to the nitrous system like normal, when the button is pushed in, the power switching from 87a to 87 and powers the transbrake and 2 step, and removes power from the nitrous system.
