Hey I'm selling a Brand New ZEX "Blackout" Wet Kit designed specifically for Scion tC1's and I believe it works with the gen 2 xB's (not 100% sure on xB's). The kit comes with everything you need, all the wiring, switches, electrical connectors several different options to choose from are included in the kit. Comes with Nitrous Management Unit (NMU) contains both solenoids(fuel/nitrous)and the electronics to engage the Nitrous and Fuel mixture aswell as all the hoses needed. NMU is extreamly simple to program; simply push the only button on it, put the peddle to the floor and your done. It has only taken out of the box once so I could take pictures of the kit to sell it. All the parts are included and have never been out of there original bags/packaging. This kit is 100% ready to go, It took me aprox. 6 hours to instal (being very cautious) instructions say about 3 hours to complete.(definitely doable in 3hrs) Comes with OE style fuel clips so you don't have to hack your fuel lines and are relativly easy to instal. No tune is needed when running the 55 shot, 65-75 shots require a tune and colder plugs.
I ended up with an entire extra kit, and thought about turning my kit into a 2 stage kit; but I decided I want to add a turbo to the mix. To do that I need to sell this first, its too much money to be sitting around. New this Kit cost me over $665.00 when I bought it last spring. I ordered factory direct from ZEX and have the invoice and packaging slips. I'm currently using this exact same kit on my tC and love it. I'm asking $550.00 shipped O.B.O anyone interested pm me. If you have any questions pm I should be able to answer them, or find the answer for you. Thanks for looking Talkshow
