There are a few kits that are plug and play for the FCs, extremely over priced. You can build your own for 1/3 their cost. S&S Autochrome on eBay carries an inexpensive IC and along with a universal piping kit. Stay away fom their turbos. Be adventurous.

My brother runs the Greddy/Trust FMIC on his TII. I agree though that a custom setup though, could save you money. Beware that its going to involve some cutting of pipes, a weld or two if you want it to be really solid, and some trial and error with the silcone hoses that connect it all up. As far as the SS turbos. They don't cost much bc they didn't cost much to make. The shops who charge more for turbos, are selling a product that has more R&D time, more testing time, and is generally a better all around product. THAT being said. You may run a SS turbo fine with absolutely no problems. OR it may grenade as soon as you make it do some hard work. The more expensive turbos may do the same, HOWEVER you have a higher chance of it happening to a SS turbo, simply bc build quality and specs are not as high as other higher priced turbos. If you want an turbo that may be a bit less pricey, try a HOLSET turbo (they're on EBAY). There are 6 of us here in my town with RX-7's and we are all running them. Do some searching on here, and you should find out what you need about them in order to make a good buy. Good Luck.
The SS Autochrome turbos are Chinese knockoffs and many of them are crap. There have been several documented catastrophic engine failure due to the turbos themselves coming apart.
