Here at Superformance for more than 36 years; we have been building performance engines using only premium "brand name" parts. To make things simple for our customers we offer an extensive range of 'Turn Key Engines' meaning that after installing one of our 'Turn-key's' you only need to connect up your radiator, transmission, fuel and power and you are ready to drive.
All of our Turn key Engines are run in and come with a metal stand for storage and transport.
