After these progresses, Cristea, together with Ion Zamfirescu [fr], a motorcycling champion, decided to modify a Ford V8 in order to attempt a top finish in the 1936 Monte Carlo Rally.
He modified the engine, which received a British-made cylinder head which reduced the compression ratio, he replaced the Delco ignition with a Vertex-Scintila magneto and replaced the stock carburettor with a double Weber carburettor taken from Maserati, he reinforced the chassis, changed the shocks with some Lincoln provenance, more rigid shocks, obtained a rigid transmission by obtaining the current effect of the limited slip differential and transformed the car's body into a roadster's body.
Together with his teammate Ion Zamfirescu and his mechanic Gogu Constantinescu he started the rally from Athens and arrived to Monte Carlo without accumulating any penalty points (like other 15 crews).
The winner was going to be selected after a slalom contest, which Cristea won 0.4 seconds ahead of Frenchman Laury Schell, driving a more powerful Delahaye.
He also wrote Dicționar tehnic auto în 7 limbi (Dictionary of Automotive Terms in 7 Languages - English, French, German, Italian, Romanian, Russian and Spanish) with Carol Szabados.
