Is this possible to be done? Do I need another coupler to increase and reduce to the piping?

 

Yea you could make it work just need a new coupler to the turbo

 

3 -> 2.5 right? I got to get my metric calculator out

 

If your trying to use it on the new style FP compressor housing then you will need a 3.5 to 3 inch reducer.

 

here is a pic of it as i got one for my fp black with my injen intak system. here you go buddy TTP charged me 39 shipped for it

 

But what about the hole that goes to the bov from the intake...needs to be plugged.

I makeshifted a kitchen drain plug to fit the hole and used some jb weld. Sounds ghetto but I assure you it looks and works well!

As far as the cupler is concerned, I used a loose one w/o any renforcements in it so It was able to stretch around the turbo and intake pipe.

 

gah maperformance sold me the wrong thing. sold me a 3"- 3" boo.
