So far, I was looking for an Andoria 2.4l 4C90 engine based Żuk: recent, as fitted since 1991, and diesel with 7L/100km consumption instead of 14L/100km for the 2.1l S-21.
S-21 itself is an improvement of the M-20, original engine of the FSO Warszawa, basis of both FSC Żuk and ZSD Nysa van. So we are talking about quite an old design.

Clearly, an M-20 based Żuk is not an option: no power (54 bhp), not much torque and mad fuel consumption.
However S-21 is said to be reliable, easy to maintain and fix. The fuel consumption is a no-go, obviously, but a fair amount of Żuk are fitted with LPG system. That could be a valid alternative to a 4C90.
A 4C90 being diesel SOHC, Single OverHead Camshaft, requires, by principle, less attention than petrol OVH, OverHead Valve (no ignition/timing issue, etc).
Great to see someone else has gone through engine alternatives! This engine is stunning. I only hope after my conversion and testing, I can re-assemble to make my engine as clean as this! Congrats. Do you have pictures fitted also?

Ahem Andy, this video is not mine. It was made before I even bought my Żuk. For now, I am still at the prepare-for-paint step. Engine tuning will come later.
