For those who haven't seen, OCD Works makes a lot of beautiful products, here is an example of a Supra VC:
In terms of materials, compared to the 2JZ cover, the N54 cover requires 'way more than double because of size'. The 2JZ cover is a two sided affair, where each side weighs 38 pounds before machining. In contrast to the N54 cover which will weigh in at 141 pounds BEFORE machining, just to give an idea how much more material is required.
Here is some other notes from Scott:
...you have much to benefit from crank case improvement. Externally large ports can be addressed and you will have better ring seal as well as increased tuning windows and knock thresholds. Cyl pressure will be lower, crank case pressure is being lowered. Better then plastic where you can't even property mount or place breather port...
...Top mount people. Sure. It will be benefit because it won't crack and melt ..but we will integrated more important factors built in so even just as a valve cover, it will be a product that can solve issues and other improvements...
I'll get more info, but for now, he's back to machining his T51R comp cover mods.
First, we get a Intake Manifold, now we have a chance to see something that can really make the N54 engine bay shine!
Lets share this post and get the word out and show Scott that we want a beautiful engine bay too!
