no, it wont hold well on the 2.5 being that it has .5 more liters of displacement, at the same psi it flows more cfm than the 2.0. this turbo will be well beyond its efficiency island if you are expecting it to hold 18-20 to redline or somthing retarded.

read the turbo faq posts, there are cfm points for the 2.0 and 2.5 at 7k rpms at different psi numbers.
