I have been running my supercharger for 15,xxx miles without a 7th with no problem and I run it pretty hard. My truck has 220,xxx on it currently.
Depending on your elevation and how religiously you are willing to run 91 or higher octane gas, you will be fine without the 7th injector kit.
I do have the TRD Underdrive pulley that I would be willing to sell. (its not on my truck anymore)
Toyota offered this as an option to reduce boost from 6.5 down to 5 psi for people who were getting ping/detonation (mostly at lower elevations) or who couldnt get 91 octane on a regular basis.
It looks like most of the major stuff is there (as well as a set of header gaskets?!?). Not sure if you just didnt post em but did he send you pics of the SC as well? lol
From what I can see there, you will need the following:
Circular Throttle Body gasket (the one on your truck currently is D shaped and you will lose about 1 psi using it. This will have to be ordered through toyota and runs about $12)
Vaccume lines/hoses. You will most likely have to install the SC, then drive to an auto parts store and measure/cut each as there are multiple lengths and sizes.
One way valve that installs on the underside of the throttle body. (this will have to be ordered from toyota and runs about 6 bucks)
Misc Nuts and bolts (I just cant see clearly enough what is there.
If you get it and are wanting to sell it, I would be willing to buy the Boost gauge and housing from you.
