You can hear the V8 sound in these videos.
The Geo was not intended to be a performance vehicle. It was a basic, entry-level vehicle. The owner of the car forgets its original purpose and adds a 5.3-liter LS4 v8 to the rear cargo area. This strange machine is available in Wisconsin for $7,000.
The powertrain has been redesigned and is located in the back. There’s no firewall between driver and engine. It is easy to reach behind the seat and hear it rumble. The four-speed, automatic transmission of the General Motors 4T80E drives the mill.
To make the engine swap possible, the builder must modify the rear end of the body. The body has fender flares that extend into the sides to direct air to the V8. The air intake is located just above the driver’s back wheel and sticks out from the body.
A fuel cell replaces the engine under the hood. To strengthen the front end, the builder adds chassis supports.
The cabin has not been modified in any significant way. The original instrument cluster has been replaced by a seven-inch tablet. The center console also has additional gauges. These seats look straight out of a Metro.
You can see the entire car in the video and hear the engine running. This little hatchback sounds great thanks to the mill.
According to the seller’s listing the V8-powered car completed approximately 500 miles of testing before winter. This included a 150-mile trip in temperatures above 85 degrees Fahrenheit. That was handled flawlessly by the car.
The V8 Metro’s excessive oversteer is noted by the seller at 65 miles an hour. According to the listing, “It begins to take concentration to maintain it in its lane.”
This video shows the V8 Metro running at 60 mph. When accelerating, the engine sounds like a small muscle car.
