Your first step in this conversion process is selecting the right engine. The Honda VTEC is a great choice, given its high-end performance and compatibility with the classic Mini. But remember, not all Honda VTEC engines are the same. You need to choose the right type that will give your classic Mini the extra horsepower it needs while fitting perfectly into the engine bay.
The Honda B series engines, especially the B16A2 from the Civic Type R, are a popular choice for this kind of swap. They are reliable, compact, and offer a good balance of power and fuel efficiency. However, if you want a more powerful engine, the K20 from the Honda Civic Type R EP3 is another excellent choice.

Before you can fit the new engine in, you’ll need to prepare your Mini. This includes removing the existing engine and making necessary modifications to accommodate the VTEC engine. Begin by disconnecting all connections to the engine, such as the exhaust, radiator, fuel lines, and wiring. Once done, you can then lift the engine out.
The original engine mounts won’t work with the Honda engine, so you’ll need to install new ones. You’ll also need to modify the gearbox. Most engine swappers prefer using the Honda 5-speed or 6-speed gearbox as they work well with the VTEC engine. However, this will require you to modify the Mini’s gear stick location and linkages.
Now comes the big part – installing the Honda VTEC engine into your classic Mini. Lower the engine into the engine bay and align it with the new engine mounts. Secure it in place and start reconnecting everything.
Take your time to ensure everything is fitted correctly. The engine should sit snugly in the bay with enough clearance for the bonnet to close. Connect the fuel lines, exhaust, and wiring. Connecting the wiring can be tricky as you’ll need to integrate the Honda’s engine management system with the Mini’s wiring.
With a more powerful engine, you’ll need to upgrade the Mini’s suspension and brakes. This is crucial for handling the extra power and maintaining safety. Install a sports suspension kit that can handle the increased weight and power of the VTEC engine. For the brakes, you might need to upgrade to a larger brake kit.
Finally, you can fire up the engine and hit the road for testing. Listen carefully for any weird noises, and pay attention to how the car behaves. You may need to make some adjustments to get everything running smoothly. This might involve tuning the engine, adjusting the suspension, or tweaking the brakes.
This conversion is a journey that is, without a doubt, rewarding for any car enthusiast. It breathes new life into the classic Mini, making it a car that not only turns heads but also packs a punch under the hood. With a Honda VTEC engine swap, you’ll join an exclusive club of classic Mini owners who have taken the road less traveled to create something truly special.
When swapping a Honda VTEC engine into a classic Mini, you might encounter some challenges. This may include fitting the larger engine into the Mini’s compact engine bay, adapting the wiring harness, and modifying the fuel system, among others.
The size of the VTEC engine can present a significant obstacle. The engine bay of a classic Mini is quite small and was designed to accommodate a much smaller engine. Therefore, you may need to modify the engine bay to create more space. This might involve cutting and welding to enlarge the bay, but remember to do this carefully to maintain the structural integrity of the Mini.
The wiring of a Honda VTEC engine is more complex than the original Mini engine. Thus, you will need to adapt the wiring harness to connect the VTEC engine to the Mini’s electrical system. This can be a daunting task, especially for those without electrical experience, but it is crucial for the engine to function correctly.
The Mini’s original fuel system may also need some modifications to accommodate the VTEC engine. The Honda engine operates at a higher fuel pressure than the Mini’s original engine, so you might need to install a new fuel pump and fuel pressure regulator.
These challenges may seem overwhelming, but don’t be discouraged. With the right technical skills, patience, and the love for engines, you can overcome these obstacles and successfully complete the engine swap.
Completing a successful engine swap from a classic Mini to a Honda VTEC is a feat that is to be admired. It’s a project that requires technical skills, patience, and a great love for engines. But the reward of hearing the VTEC engine roar to life in a classic Mini is priceless.
The resulting car is a unique blend of classic British design and modern Japanese engineering. The classic Mini’s iconic design combined with the Honda VTEC’s high-end performance creates a car that turns heads on the street and provides an exhilarating driving experience.
The journey to a successful engine swap is not without its challenges. From selecting the right engine, preparing the Mini, installing the new engine, and overcoming various obstacles, it’s a project that will test your mechanical skills and patience. But it’s also a project that car enthusiasts will find incredibly rewarding and fulfilling.
So, whether you’re an experienced mechanic or an ambitious DIY enthusiast, swapping a Honda VTEC engine into a classic Mini is a project worth tackling. With careful planning, the right tools, and a strong passion for cars, you can join the exclusive club of classic Mini owners who have carried out this exciting VTEC conversion.
