how do you tell the differance between
a 4x4 saph/big turbo escos plenum
and a small turbo escos eeciv plenum

i know the differance between 2wd and 4wd but never paid any
attention to the small turbo plenum?
is it a direct fit to a 2wd trumpet section,
i'm sure the sensors are differant but can they just be swapped over?
basicaly what needs done to fit it?
