Mazworx | 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.

yup, same parts and method used to build my heads as well. You guys are using the 80lb double valve springs right? Which cams? If C9s, it will be cool to see how much machining you needed to do to make em fit. I didnt wanna mess with all that, along with the mechanical VTC stops.
for 1200whp, i assume you are using 62mm or bigger twins. Hopefully 67mm!! In house kit?

We will be using a Garrett 4718R

nice! 1/2 sized radiator. Do you have 1/2 sized ac condensor as well?
a T6 88mm turbo is excellent! Are you building the manifold around a quick spool valve?
Why the garrett over say a ProMod88 or PTE 8884 billet?
Already see you built custom motor mounts to fit that beast. Did forward facing next to the radiator not work?
