its just like building any other turbo. rebuild the motor so it doesn't think about blowing something when you boost it. running 7-9 psi shouldnt be a problem on stock internals but dont forget to get the car tuned.

heres mainly what you'll need-
1. rebuild kit (come with replace gaskets/rings/rod/piston)
2. turbo manifold (since its not a sports car you may need a custom made turbo manifold)

stock internal rebuild shouldn't run too much, ex: b18b1 rebuild kit is 300-400 $$
