Anyone fancy to speculate how an EFR 7064.083 on a std 4x4 cosworth manifold (T3) would compare against an EFR7064.092 twin scroll on a nortech twin scroll manifold?

Various after marked turbine housings may also be an option to combine with std manifold https://www.turbozentrum.de/BorgWarn...3-Single-063ar

 

..twin scroll is way better ....my car was transformed with twinscroll

 

better, as in much faster spool, or better as in more high end power, or both?

 

...i would say both,generally car drives much better picks up fast nothing like before ...before seemd like it had flu....had gt30 and after gen 2 gtx than twin scroll..
