Long story short I have been searching the Internet and local junkyards for a turbo diesel truck that I can take the t from, among other options. I'm considering both a holset and a CT26 (mkIII supra). To flow this boost, do I need custom headers and a 3" DP? I'm fabbing a 3" "cobra pipe" and want max airflow for max power. Ignore the blasphemy of fitting a supra turbo in a saab.
