Hey bud, we have a Boost section. Should answer most of your questions there. Also the doing a search would help to. My honest thought is that for the money and what you would be getting. Revhard or Cybernation. Pretty much complete kits, while the Greddy is lacking. Hence in the long run you will pay more for the Greddy, and have a greater chance of screwing something up. While Revhard and Cybernation sorta figure that stuff for you already.
Also it is easier to get more power (upgrade) out of a turbo set-up. If you just wanted alittle something, that you can live with than you cannot go wrong with the JRSC.
