For whatever reason you may choose not to IC your truck and have swapped to 38r.

Here is the intake part# that is a direct fit from turbo to 3" intake runners. Only took me 6 years to figure it out....

XC2Z-6K889-AA

 

I suppose the turbo outlet is different on the 38r and Tp-38's right? I want to do 3" plenums now but am not doing my turbo setup until later.

 

Yeah they are different. You can just get an adapter to go from the stock (is it 2") to the 3" allowing you to reuse your current stock turbo outlet manifold.

 

Yah stock is 2".

 

Sd van outlet makes it nice n easy.
