    Should be a 100% bolt-in with a couple of ETACS setting changes. It would very likely run well enough even without changing the ECU, just might run rich at WOT and at start-up.

    The 3A92 is just a stroked 3A90. Exactly the same engine, just different crankshaft and/or connecting rods.

    It should actually be possible to convert your 3A92 to a 3A90 if you really wanted to.

    /\ This. The hardest part would be finding a 1.0 to swap in. Otherwise, it is like swapping an old Ford 352 for a 428.

    If you want a car with a 1.0 L engine, buy an old Metro.

    Custom is expensive.

    Crank and rods would be cheaper to ship from Europe vs a complete engine. But, you'd spend so much on machining and gaskets and other stuff (to do it right) that it would surely be cheaper to ship a whole engine. The engine only weighs like 120 pounds.

    You COULD even just have somebody ship you a short block. Without all the accessories and the head, the bottom end would weigh less than 90 pounds probably. But, again... then you'd have to buy a new headgasket and do all of that assembly.

    Probably cheapest to find a low-mileage Euro 1.0 and just have it shipped. Compared to "typical" engines, this thing is REALLY small and light!

    I'm all for doing things just in the name of experimentation and just to say you did. But... why would you want to do this? You're going to spend probably $600+ for the engine, plus at least $200 (that's probably very low... would cost $200 to ship it across the US) shipping, and more for odds and ends. You're looking at easily $1000. You'd have to drive an awful lot of miles to account for that cost. Economically, it probably doesn't make sense.

    Okay, so "just because". Fair enough!

    I had a 1987 Chevy Sprint that my wife bought brand new. We drove that thing everywhere! Easy to get 60 mpg. No air, cruise control, or power windows. Those Suzuki 3 cylinders were great. It was one of the primary things that made me get a Mirage. The Mirage to me is the 21st Century Metro/Swift/Sprint which is why I enjoy them so much.

    I'm currently driving a 1.0 swap!

    I swapped my 1.2L Mirage for my 20 year-old 1.0L Metro.

    Advice: stick with the Mirage.

    I did the same. Haven't missed the ol' Geo one bit.
