Turbo Set-up Help

[Speed_H4ck]

So I bought a Mazda MX-5 MK2 1999 earlier this year and I told myself I wouldn't modify it, however, now I want to add a turbo in it. I want to play it safe and reach around 230bhp. I dont want to change stock internals. Budget isn't as issue but I would like cheap and reliable alternative suggestions for parts please. I have been doing some newby research and I came to set-up list. Guys, lets me know if you think this is ok. I'm open to criticism so criticise away.
