The last comparo is a highly tuned GT3782 on an STI. Custom engine build - To really make power on these engines, a custom engine build with increased compression, improved cylinder head flow is required. Engine balancing - to ensure a well balanced, smooth and rev-happy engine, balancing of the rotation bottom end components is essential. This is the most popular option for those wanting a solid increase in power due to the improved efficiency a turbocharger offers. The first generation EZ30 had a single exhaust port on the head, which impacted free gas flow, but was required for the engine to meet its emission standards (the purpose of this strange exhaust port arrangement was to get heat in the catalytic converters as soon as possible). Earlier Legacys can run flex-fuel with an aftermarket ECU. We know of instances where more power has been made, however, there is reasonable risk involved with increasing power levels and boost on an engine with a block, pistons and other components not designed for the purpose.
