Which S400

[TSPowell]

Borg Warner makes several S400's, does anyone know which one is the B2? I think its part# 171702. Also, is this the same B2/S400 that sourceautomotive and MPI are using for twins. I think the most common either come with a 75 or 80 wheel.

Nobody has a guess?

I asked Nathan at MPI and he told me he uses the 171702 turbo and says its the biggest S400 you can get without going to the S480. Hope this helps!
