Also a nice cheap motor mount upgrade is the civic type r / Integra type s rear motor mount is a direct swap and/or get the poly insert. Don't get anything too stiff, Honda cheaped out on vibration control i.e. the interior panels annoyingly make noise under vibration.
dp ~ 6hp mid , 12hp peak
prl fp ~ 2hp mid , 1hp peak
prl sri ~ 6hp mid, 3hp peak (if not heat soaked)
Thermal r&d exhaust ~ 2hp
These are guesstimates based on other dynos of individual parts, so ABOUT +16Hp midrange, +18hp at peak.
Your next upgrade should be a larger intercooler and charge...
