If I got a D series kit could I just get some custom piping to fit a B series? Thx.

 

pretty much gotta just modify the manifold a bit. The piping can be modified to fit for the most part.

 

Yes, just get a copy flange made and welded to the D series manifold. You can use the charge pipes, but will need to get custom bent I/C piping and prolly a new down pipee.

Depending on the manifold, watch out for fan clearance.
