I bought a kit off of ebay, just do a search for "flame thrower" or some variation. The kit says it is "complete" but all i could use was the "hot box" that basically acts as a dizzy for the coils to store voltage, then release. I went to a local muffler shop and a guy i know there had 2 O2 sensors that i then took to auto zone and matched thread with 2 spark plugs. Autozone also had ready made wires, so i bought 2 of the longest ones that they had that would connect one side to the coil and the other to the spark plug. The kit also comes with a relay, witched is the same as the fuel pump relay off of a 2000 Ford Taurus 3.0L It comes with directions, but because i have an MSD box i had to improvise. To shoot the flames, you rev the motor to 5000 or whatever, lower works but less size flames and shorter duration - then i click a button after activating the system that kill my ignition. I pump the accelerator to dump raw fuel into the exhaust pipes that then gets ignited on its way out. I then click the "ignition kill switch" off and the car spins back up to 5000 and i do it again.
let me know of anymore questions you may have
