Miata NB Intake Manifold DBW Adapter
thingiverse
Adapts a 60mm Keihin DBW throttle to a NB Miata Intake Manifold.Readily available part found on the Honda 2.0L turbo engines (K20C* variants) found on the Accord, RDX, TLX, Civic, etc. Shown on a Junk2 inmani, but I modeled it using the common flat/square top inmani. The Junk2 does have a lot more room, but it fits with the flat top and stock NB fuel rail. You will need to use a K24A2 DBW paper gasket to seal the DBW to the adapter and use a standard Miata throttle body gasket between the inmani and the adapter.I ended up getting this CNC'd out of aluminum, since I didn't want to deal with strength and porosity issues with FDM printing.
