When it comes to building boost, there is no one-size-fits-all answer. However, a two-step process can certainly help. The first step is to find out what your engine's limit is. This can be done by revving the engine and noting where the needle starts to fall back down. Once you know this number, you can start working on increasing it. This can be done through a number of different methods, such as porting and polishing, installing larger valves, or changing the compression ratio. The second step is to actually increase the amount of boost that your engine produces. This can be done by adding a bigger turbocharger, increasing the size of the intercooler, or making other changes to the intake and exhaust system. If you're not sure where to start, consult with a professional tuner who can help you get the most out of your setup.
