Honestly, no offense but it seems you dont have a lot exp. so I would just pay to have it done right.
ERL B18A/B Sleeved Blocks
Thats a good place to send your block or buy a built block. There are cheaper places but you get what you pay for and working with turbos and the power you want do it right.
The easy way would be to buy a pre fabbed turbo kit by a reputable company like maybe a full race or similar company.
If you think you can piece together all the parts yourself then go for it. I have seen guys with homeade turbo kits putting down almost the same amount of power you want using junk yard shit.
There is a build here that would be perfect for you to read.
