12v for Oil Pump on Turbo Lifan Project

Trying to finish up my turbo Lifan project. Does anyone have any tips on getting 12v from the stock flywheel to power the oil pump? I read I need a genuine GX160 Honda flywheel to accomplish this. Is this true? Any tips would be great!

Tracey's top notch fabrication skills are clearly showcased on this creation. Apparently built as a result of a dare by friends, the chassis is constructed from 4130 tubing. Power comes from a Honda 160cc single cylinder engine fitted with an IHI turbocharger. A ceramic coated, 2 inch exhaust dumps the fumes. A custom, billet, belt driven, oil pump was fabricated using Cummins fuel pump gears and Bosch relief valve parts. The fuel tank was hand fabbed from .080 aluminum. Braking is by a Hurst/Airheart hydraulic kart setup with cross drilled rotor.
