There is a question that has been bothering me around. I'm wondering if displacement of the engine really affects the horsepower output of the turbocharged engine. Lets say i got a RB26 engine, at 2.6 litre, running twin GT-SS turbos. This engine will be producing around 450-500 hp. Now, let's say i bore the engine up to 2.8 or 3.0 litre, still using twin GT-SS turbos, will i get more than 500 hp? Another question, say if i swap the engine for larger displacement engines, like a VK45DE engine(4.5 litre), still running twin GT-SS turbos but with the addition of external wastegates, will i get more than 500hp?
