We can port your head and build your engine to whatever spec (bhp) you require. The MX-5 NC had arguably the best engines of all – the Mazda designed Duratec I4. Not only is it capable of great reliability and power outputs it came in 4 different capacities; 1.8, 2.0, 2.3 and 2.5. This is where things get interesting – they all look similar externally and are interchangeable with some minor modifications. Everyone’s needs are different from a remap to a highly tuned two litre, budget 2.3, very rare 2.4 or a more expensive 2.5 we can do it.
