What all do I need to get ? Whats the difference between 1st and 2nd gen ? From what ive read its nothig. The 1st gen is louder thats all.
Both 1st, and 2nd gen chargers utiize the eaton M62 blower. They both flow the same. The 2nd generation supercharger is black, and a 1 piece design. and a lot better looking than the grey 1st gen, which is a 2 piece design. But if you get a 1st gen charger, you will most likely want to rebuild it before you put it on. You can get a full rebuild for around $300. Just make sure if you buy used, you get all of the accessories. you need the dynamic tensioner, all of the mounting bolts, 1 way check valve, and either the TRD throttle body gasket. You can also modify the stock aluminum gasket to work if need be. And of course, you need the belt.
i am not running a fuel kit at all, and i have not experienced any pinging issues running premium fuel. I may eventually do a fuel upgrade. I have seen the 7th injector kits go for around $4-500. I would probably just go with a set of supra mkIII injectors, with a greddy emanage, instead of the URD kits. i have seen a few of those used, but are still pretty expensive. I figure i can get an emanage used for about $250, and you can get the supra injectors rebuilt, and flow tested for about $30 a piece on rockauto.com. If you want to save some $$ on a fuel pump, you can go with a 3rd generation rx7 fuel pump. These are readily available used on rx7club.com. You can pick one of these up for around $30. They flow more than the walbro everyone uses on here.
BTW, for the other poster. I installed my supercharger on my 4runner at 154k, and i now have almost 160k on it, with no problems with the engine. As long as the motor has good compression, it doesnt really matter how many miles are on it.
