I have come across a Garret T-25 turbo. Has minor in-play. The thought of putting this on my 5sfe has crossed my mind.

But, this idea is basically a starter idea. If it would work, it would eventually be upgraded. I have read that the T-25 has been used for the 4a and 7a motors, would it be beneficial to a 5s?
Plan: start as a 5sfte, ( At a low boost of 4-6 lbs no higher )
aquire more parts,
build into a 5sgte!!!
These are big plans. But, I want to do it in steps.
So, would the T-25 be a good starting turbo? Should I keep on for the CT-26 or larger? I know if I wait for much a larger turbo I need to upgrade all at once to have it functioning healthy.
