Live Poll

Would you consider purchasing a heavily modified custom vehicle for your personal use?

A highly modified Geo Metro is drawing attention after appearing on the online auction platform Cars & Bids. The vehicle has been converted to house a massive 5.3-liter V8 engine where the backseat once was.

Why it matters

This build represents an extreme example of engine swapping, as the stock Geo Metro was originally equipped with a modest powerplant that produced only 55 horsepower.

The custom vehicle is powered by a 5.3-liter LS4 V8 engine capable of delivering 303 horsepower and 323 pound-feet of torque. The drivetrain is paired with a four-speed automatic transmission.

The players

Cars & Bids

This is an online automotive auction marketplace that specializes in modern enthusiast vehicles.

The details

To accommodate the massive drivetrain, the builder cut, widened, and reinforced the vehicle's body to fit a custom subframe. The cooling system is relocated to the rear, while a racing fuel cell now occupies the front engine bay.

Roadmap

This project highlights the ongoing hobbyist trend of transplanting modern, high-output engines into lightweight economy cars to achieve unique performance characteristics. Such builds reflect a broader DIY automotive culture that prioritizes mechanical engineering ingenuity over factory specifications.

Potential buyers should note that this vehicle is currently registered in Illinois and features extensive custom fabrication, which may impact future maintenance and serviceability. Interested parties can track the auction bidding activity directly through the platform listing.

The takeaway

Extreme engine swaps require significant structural reinforcement and custom cooling solutions to remain functional. Enthusiasts should prioritize assessing the build quality of custom subframes and structural welds when evaluating modified vehicles.
