Nash Metropolitan drive train upgrades - I have seen a few that are practical for the small engine bay and relatively inexpensive to purchase. Ford small displacement 4 cylinder engines work.  Look at Pinto & small ford industrial engines Another popular engine/transmission upgrade is the GM Chevette.  I personally installed the Chevette 4 cyl engine & automatic transmission into a 54 Metro.  It was fairly easy to install & fit into the engine bay with only a few small modifications.  Easily made new engine mounts and tube style transmission cross member.  The car drives wonderfully.  Also about tires - radials are available but do not mount a wide radial as it will rub on the front coil springs unless a 1/4" spacer is used. Use a tall narrow radial or original design tires as the rims are very narrow. Note: everything on engine is opposite original engine. Meaning carburetor, manifolds, linkage, exhaust, etc is on opposite side, even radiator hook-ups & yes I used the original radiator.  Finding a good used Chevette engine/transmission is getting harder to find but they were very durable and can go over 150k miles and more. They are available with auto or 4 speed tranys.  If keeping original engine/trans then find a rear axle center section with a ratio of 3:90 and install it for more speed. Use a hot rod wiring kit to easily wire everything for 12 neg.
