[Gasoline Fumes]

Luckily most Japanese cars use Nippon Denso or Nippon Seiki gauge clusters. They are for the most part, electronically interchangeable between Japanese cars. Convert the CRX tachometer to work with a 3-cyl engine and the Honda cluster should work fine with the Suzuki engine. The gauge side of the speedometer cables should be the same, so use the Suzuki cable if it's long enough. I'm not sure if the transmission ends are the same or not. Both Honda and Suzuki speedometers should be 1026 revolutions per mile. The Suzuki (Denso) ECU will expect to see a VSS signal from the speedometer, but I thought all PGM-FI Hondas had the VSS. I know disconnecting the cable on a 1991 Civic Wagon results in a check engine light. But if the cluster really doesn't have the VSS, you should be able to take the cluster apart and add one.
