Stage 3 - Engine Internal optimization
Stage 3 is where we get serious about maximum efficiency. At this level we are delving deep into the engine to improve efficiency (Lighter weight components, polishing to reduce friction, etc.), add displacement, and possibly forced induction, all of the way to complete re-builds.
o Head Work (Porting / Polishing)
o Balancing / Blueprinting
o Adding Displacement
o Forged Internals
o Forced induction (Turbo & Supercharger)
o Full re-builds
