Just as an FYI, I had a spare del sol S intake manifold laying around (d15b7) and my buddy has a 91 dx hatch. The manifold does work as long as you use the d15b7 or d16z6 tb. The Z6 intake manifold doesn't line up right... He got a nice power bump from it, but has been plagued with dist problems since the swap. Can't find a good TDC sensor to save his life! Let me know if you guys have any questions...
