Ferrari fans should look away as this 308 GTBi no longer has a V8 made by Modena, and now there’s a turbocharged Honda K24 occupying the engine bay. This video shows the first startup of a swapped powerplant.
The clip embedded above starts just as the engine is turning. The hoarse staccato sound of the Honda engine makes it sound like the world’s craziest popcorn popper. The cause of this interesting sound is the removal of the Vtec system, according to video host Mike.
The engine runs on a modern ECU which allows on-the-fly tuning. People who own laptops make these adjustments to adjust idle speed and monitor the air-fuel mixture. The current cooling system is not working, so they cannot operate the power plant for too long.
In the near future, Mike wants to have a cooling system. The car still needs axles too. A set of wheels is also a necessity. The interior needs some work as the passenger side currently holds the messy wires.
If you want to know the details, then we highly recommend watching the beginning of the video where Mike gets ready to run the engine. The work included assembling the battery case and attaching the necessary oil lines to the dry sump system. He makes a lot of his own fittings and does a lot of his own TIG welding.
Mike intends this Ferrari to be a time attack car. As the name implies, this form of motorsport is not about door-to-door racing in an effort to reach first place. Instead, competitors seek to organize the fastest laps around certain circuits.
Since this Honda-powered Ferrari had racing ahead, Mike tuned it to run on 110-octane gasoline. He thought he could find this fuel on the track too.
The reason for this swap was because Mike felt the 308 GTBi stock was “underpowered, overweight, and overpriced.” He’s probably right because in the US this fuel-injected 2.9-liter V8 makes just 202 hp. This may have been fine by early 1980s performance standards, but Mike showed there were ways to generate more power today.
