The problem with the 2.5 is it has taller intake ports and matching intake that does not have the charge plates and other sensors on it like the older models

I plan on buying an adapter plate I have seen others use from eBay, and then using basically all my 2.3 pulleys and parts and sensors is there anything else I have to switch?

If you not swapped it yet, the 2.3 has another clutch. What you already buy for swap?
