Hi my set up is a half bridgeport 12a with a GT42. Well i have two intercoolers. one the inlet and outlet are 2.5" and the other one is 3". I am thinking use the 3" but i want to know what you guys are using with gt42 or other big turbos.

 

i run a 42r and use a 3" inlet and outlet. core size is 24x12x3 i think

 

I run a 42 and have 2.5" piping... no problems for me

 

I run a 42R and I use 3"

 

got any nudes of that skank in your sig ?

 

Thanks everybody. I am going with 3"
