2.5 Plus a Turbo??

Turboford.org has more detailed info, but results show that breathing and efficiency mods such as porting, cam, intercooler, exhaust are more cost effective than .2L of displacement.
Example, TF member Greg O'brien is building a drag car and is expecting to make well over 400 horsepower and is still using a standard stroke 2.3.

Basically figure out roughly how much horsepower you expect to make and then divide that by the cubic inches. Now take the number representing hp per cubic inch and multiply that by the number of cubes for the 2.5L

2.3L - 140CID
2.5L - 151CID

So lets say a 2.3L turbo makes 200hp. That would be 1.428hp per cubic inch

That would mean a 2.5L version would make about 215.628 hp.

Now a 300hp 2.3L would mean the same motor would make 323.442hp

This is just an example and doesnt take into account other factors like drag, volumetric effeciency, etc.
