The Secret To Buying An Engine For Your Classic Mini
Whether you’re simply replacing your Classic Mini’s engine or moving up to a powerunit that’s got more muscle, buying an engine is a complicated matter. How much power are you looking for? How authentic is authentic? What options should you consider? What option are available that you didn’t consider? (Believe us when we say the options available are mind blowing.)
So it’s not surprising to say the secret to replacing your Mini's engine is...call someone who can guide you through the process. Find an expert who knows Mini engines and understands that no two engines are alike.
For example, maybe you want an aluminum head rather than the traditional cast iron head. Or competition head studs rather than classic studs. Maybe you don't know the differences.
Our experts can identify your needs (and wishes) and work out a detailed plan to get you the engine you want.
And before you call – here are some things to consider:
Restoring or Replacing Your Engine
There is a wide spectrum of options between restoring or replacing your engine with many nuances in between. For instance, we offer off-the-shelf replacement 1275 engines that range from a standard engine with cast iron heads, a 3.4 Differential and a 4 speed gearbox to a High Performance engine that features a 5-Speed Transmission, Aluminum Head, 3.4 Differential. LCB Header, etc.
Or if you’re looking for something more powerful, our 1380 engines range from a Street Model Engine (with 73.5mm squeeze-cast pistons, 10:1 Compression, A+ Block, Crank, and Rods for best big bore reliability, etc.) to our High-Performance engine with an A+ Block fully prepped and off-set bored to 1380cc, 10.5 to 1 compression EVO 9cc dish pistons, reground A+ crank with +.010" or +.020" bearings, etc. etc. etc.)
It all depends on what you want.
Tested Pre-Owned or Rebuilt Pre-Owned or Brand New
Or maybe you’re looking for a pre-owned unit. Our pre-owned assemblies include everything from cylinder head to clutch and transmission. They’re fully inspected and approved and are ready to bolt in to your Classic Mini!
Need something more? Then maybe our rebuilt, pre-owned units are better suited for you. These pre-owned rebuilds have all been tested here for compression, oil pressure and blow-by and then reassembled to include from cylinder head to clutch and transmission. These units are also ready to bolt in.
Or perhaps, our brand new engines fits your needs. We begin with a pre-owned core, recondition things like rods and crankshaft and replace old items with new such as pistons, bearings, etc. so it's almost like getting a brand new engine.
