Supercharger ideas/Questions!!!!!!

I have a 2002 taco with 180k on motor. I have a used S/C. Found a site for rebuild parts. I cannot find the installtion kit. I work for Lexus and have asked the Toyota parts here at work if they can just get me the install kit and they said they cant. I need that kit and if anyone knows where i can buy one please please let me know! I also need to know if I should do the other upgrades such as the 7th injector and the urd pulley. I also need to know what kind of guages I need to run for the best quality. I was thinking i may need to update the ECM with a piggyback of some kind but im reading thats not always needed. I have read that since its made by toyota that I really dont need any extra stuff as its made to go on a stock engine. Seeing that I have 180k on motor do you guys think it would be wise to go ahead and do the upgrades? Just need some ideas and suggestions on this bc im new to working/building a motor thats supercharged.

Really Really need the installation kit!!!

Please help!!

 

Hopefully this helps!
