We've seen our fair share of engine-swapped Minis, from Honda's B and K series to Suzuki Hayabusa motorcycle engines, but this EJ25-powered Mini takes things to the next level. Steve from ‪@DutchysGarage‬ has crafted something truly unique: a 1961 Morris Mini transformed into a mid-engined, RWD beast, all thanks to the heart of a 2010 Subaru WRX EJ25.

This 'MiniRex' stole the show for us in the World Time Attack Challenge carpark, with Steve personally handling 99% of the build himself —impressive work, especially given Australia’s strict vehicle regulations, which was one of the reasons for using an older pre-1973 chassis. The impressive 1-man-band craftsmanship and road-legal engineering make this build a real standout, combining eye-catching aesthetics (who doesn't love a sunroof!) with serious performance potential.

Key Build Details:

• 1961 Morris Mini – Mid-engined, RWD conversion • Subaru EJ25 engine: Essentially stock, producing 250hp and 400Nm of torque • Haltech Elite 2500 ECU with an iC7 dash, sensors, and wiring harness • Process West intercooler for added cooling performance • 3.9 final drive ratio for optimal gearing and acceleration of the 15" wheels • Mazda MX5/Miata suspension, hubs, and subframe integration • Viking coil-overs • Subaru inner CVs, custom axles, Mazda outer CVs • 2003 BMW Mini panoramic sunroof – because style matters too! • An unbelievable power-to-weight ratio, making this Mini a true sleeper
