<p><span>At stage 3 we go a step further, we are going to replace the internal or vital parts of the engine or turbocharger, this can go from increasing the cylinder capacity, placing sport camshafts, to the installation of a larger turbocharger. Sometimes there are some inherent risks to reliability, but not always. Manufacturers often build 1 basic engine block and by using a larger turbo and injectors they can build 2 capital versions. It goes without saying that in some cases you can boost your engine with original parts of the heavier version, without affecting the reliability because the manufacturer already had been anticipated.</span></p>
