well... i do know 3500 is a lot, and he told me: "The turbo would be somewhere around 3500 to 4000 for the bolt on system" then, power hungry me asked about 10 psi and installation, so he said that would be more expensive...
anyway, as i was saying before, its all about getting the best parts for our cars, and im guessing thats no custom job, once he does one, we would see it for sale from their site. He said he needed either a p5 or an mp3 for 3 to 4 weeks.... and 3500 (the cost of the system) in my case he was going to change the fuel injectors and other stuff in order to get to 10psi

and installation.
well, actually i believe i can work out installation with him in case is the guinea pig.
In short, im sure we can get something cheaper, but will it be as good as this one can be?
also, for the person who mentioned greddy, they already said no for our cars.
