Tach Test (Datsun Roadster with Miata Engine)

Автокөліктер мен көлік құралдары

I've temporarily mounted the tachometer from a Miata gauge cluster on a homemade bracket in the hole where the stock Roadster tach used to be. See the build at www.orange-claw-hammer.com/tmp/rs

    @Smatchimo - The speed of the oil pump is directly tied to the speed of engine, so the faster the engine revs, the faster the oil pump pumps.

    Is there anyway to hook up the stock speedometer and tachometer to the Miata engine?

    I never did, but I researched how to. With the speedometer, you have two options -- one somewhat inexpensive and hard, the other easy but somewhat expensive: (1) get an early RX-7 mechanical sender (my recollection is that you want the one with the purple plastic gear -- the colors denote tooth count) and drive gear (need to take rear housing off to get drive gear). Notch the Roadster X-member to create clearance for sender cable. Probably have custom extra long drive cable fabricated. (2) Buy a GPS speedometer sender ($90-250). Buy a digital signal to mechanical drive speedometer box ($284-345). Plug them in and run drive cable to gauge. For the tachometer, I would have a gauge shop convert it to take the tach output signal from the Miata ECU. The reason I don't recommend this approach for the speedometer is that it's unlikely to produce a good solution to the odometer and trip meter.
