Obtaining a turbo package is also a viable alternative. Since they have new seals, lines, waste gates, and new manifolds, all of that happen to be mounted by an easy bolt-on treatment. Turbo kits are a cheap and straightforward way to boost energy output and throttle reaction. If you need to thrust over 600 horsepower, you have to upgrade the internals, including the camshaft and cylinder heads.
