To answer the OPs question, my turbo is a garrett polished compressor side/turbonetics exhaust side T3/T04E 57 trim .63a/r with a stage III wheel in it. Good power comes out of this turbo, it likes high boost for sure!
Like I said, you won't see the gains you'd think you would out of a fuel cooler...at 50+psi fuel pressure the fuel is flowing through the lines and whatnot so quickly it wouldn't be in the cooler long enough to make drastic drops in temperature, so your 40 bucks is better spent on 3/4 tank of gas lol.
C2K: While I do believe I'm a great help in the fuel section, I do not know everything that's out there and I give most of my information based solely on personal experience. I built my fuel system from scratch, built my turbo setup from scratch, fabricated my dump tube and 02 housing (pain in the ASS lol) did all my electronis myself and tuned the car myself. Alot of this took place over a period of 13 months through trial and error, but it has netted me 400 horsepower for under 1600 dollars after everything was said and done

That's mainly where I get all my info from, plus being on the forums and taking in as much info as I can doesn't hurt either lol.
