2L8v8

I recently got a eg hatch and been weighing the options of built head w itbs, small turbo, or a centrifugal sc. Did some research and came across a few people boosting running high compression. I would like people with first hand experience to chime in. numbers I really dont care about, and budget doesn't really matter. I would like somewhere around 300hp with great reliability. The internals on the b18c is stock and its a 98 sir motor w only 66k on the clock. Whether its turbo or sc just would like to know size, internal/external waste gate, and how much boost. Thanks alot guys
