Anatomy of a 4.1L 1200+whp VQ engine build
We here @ Mazworx are building a monster VQ engine for our new engine program. In this thread you will see the step by step process to create this engine. We shall first start off with the cylinder head.
Here you see our port work. This is the exhaust side of the cylinder head.
Here is the combustion chamber opened up to match the bore 100mm and deshrouded. This process eliminates hot spots and reduces the chance of detonation.
All oil passages on the head are cleared, cleaned, and tapped for plugs
Cylinder head here is cleaned, ported and ready for machine work
Getting ready to install Supertech valve guides
Cylinder head clamped in the valve seat machine ready for machine work
Valve job being performed
Right valve shows the final deshrouding radius
With the valve open , the deshrouded valve has more space around it. This allows more flow. Using Supertech inconel exhaust valves.
A complete 5 angle valve job
Valve job on the head completed and ready for assembly
Getting ready to install the Supertech valve seals
OEM Spring seat, Supertech inner spring seat, Supertech valve seals installed
Installing the Supertech dual valve springs and titanium retainers.
Cylinder head being resurfaced
Once head is completed, we install a spark plug and the chamber volume can be measured.
We will be back shortly for the shots of the engine block work.
