I have to order a few more bends and what not for the pipe from the turbo to the intercooler. The turbo is a decent size ( precision sc61 ), and people are telling me to go with at least 2.25" piping, 2.5" would be ideal. Now when I measure the outlet on the turbo the inner diameter is only 1.75" and the total diameter is 2". Now wouldnt it be fine just to run 2" piping into the intercooler, and then 2.25" out? It seems like there is no need to go from 1.75" to 2.5" right where my lower piping would meet the turbo ... although I do understand that after the intercooler it would make sense to make the piping a bit larger. Can someone explain to me why 2" piping in and 2.25" piping out of the intercooler would not be sufficient if the outlet on the turbo is only 1.75"? I'm not arguing or anything, but just trying to understand. I know the greddy kit uses 2.0" in and 2.25" out. What's wrong with this? Thanks to whom ever can explain it!!
