The sensors are not there I dont think. You will have to get them from a Turbo Diesel engine and prob fit the sensors. ALOT OF HASSLE! Its not worth it. You could buy a turbo diesel 205 lump and fit that with the wiring loom? Still lots of work. I fitted the engine but not the loom and dont mind that I dont have a rev counter.

Yes, you can fit a rev counter (tachometer) to a Harley-Davidson 883 Sportster. You can either purchase a compatible aftermarket tachometer designed for the Sportster or use a universal model. The installation typically involves connecting the tachometer's wiring to the ignition system, often at the coil, and mounting the gauge on the handlebars or dashboard. Be sure to follow the manufacturer's instructions for proper wiring and installation.
