look at the link i posted from my350z that kit will set you back 3100€ plus shipping and tax. then you'd need to decide what route of ems you'd like to take, utec (500$), Uprev (think abbey no do a replacement ecu that you'll be able to change maps if you got a cruise control), haltech, motec... if you go for the tt mid turbo kit its made for built systems so keep the boost low and once you get bored of that power you build your engine and increase the boost... simples!
(+ that the kit seems / sounds to be a DIY kit!!!)
