@dejavoo bro u need to do a good deal of knowledge about the car's engine then the turbo its self plus even honda vti's engine which is said to be a storng car can hold upto 9psi the cultus though efi but being a 1000cc motor with even weaker internals then honda's motor can only stand approx 6psi of boost.now for gaining 6psi boost spending around 70k is not worth it i think.plus u cant get the turbo charger on just a new motor out from the factory u need a lil milage on it so that the due to slight internal wear n tear and obsolesence ur internals get to their right position.
