You can throw on every bolt-on available and a Hondata ECU and with tuning maybe get 200-225 HP at the wheels.  I have a completely built d16y8 that is turbocharged and is putting down 266 at the wheels w/13psi.  I had way too much $$ invested in this motor w/bolt-ons when it was N/A to consider an engine swap, so I went crazy and replaced the top and bottom end when I had the turbo installed.  Hitting 300 HP shouldn't be a prob when I upgrade the injectors.  I would also consider a K-swap.  Minor bolt-one to that engine will net 200 HP easily.
