So this is gonna be a dumb question. But would a 2016 mercedes-benz cla45 amg engine fit in an automatic 2012 eclipse gs sport?

Yeah it would fit. And then you'd be running lower displacement with the same rod ratio as you have, with a heavier engine, with a heavier rotating assembly. You'd also need to run a standalone ECU, you'd be stuck with direct injection which quadruples the cost to add performance and has many non money drawbacks (DI gains are at fairly low power per displacement, and more for emissions), need to change transmission or make an adapter plate, may need custom gauges depending on which standalone you used, and you'd be at the power level a stock 4G69 with an ebay turbo slapped on it does. They do 375hp crank at 26psi boost factory, we do about the same at around 10-14psi

Unless of course you live in a region where the GS Sport was the sun and sound package, and auto trans, in which case, no, it won't work with your transmission, and a turbo 4G69 won't be worthwhile either, as you'd have to cap yourself around 5psi boost, making a GT more viable.
