the FMAX kits sell for about $3500. hookup prices can get it for around $2800 if you look hard enough. i bought mine used. it had about 300 miles on it. i got it for $2300. the kit comes with a bov and wastegate. it comes with the Deltagate and HKS racing. the Deltagate is notorious for having boost creep. boost creep is when the wastegate is set to 8lbs and once in a while it will go up to 12-13lbs. obviously thats very bad. and i have just always loved the sound of the type-s bov so i swapped them. the extra injectors arent always on. they are closed until it reads 2lbs of boost. then they open up and inject fuel. so its just normal gas comsumption unless you go over 2lbs of boost. the displacement stays the same. the only way that changes is when you mess with the internals and block. i dont really like the way turbokits.com sells kits. its not really for the novice to buy from them. they offer kits by saying "70hp increase" and "100hp increase" mostly the only difference is how they upgrade the fuel system. they dont tell you that its with more boost. some people say "oh i'm gonna get the 200hp kit" but they dont realize that thats on 20lbs of boost which will also require you to build the block. they fail to mention that
