Oooh. Art.
 

So, why's the head off anyway?

That looks really nice!

because I was having them flowed and portmatched to the RS4 intake

here's the full res, hosted on my dsl . . .

That sounds expensive...what other mods are you planning...the RS4 turbos?

Here is one post from the S4 forum
 

Basically trying to do all RS4 stuff . . .

Someone asked about ceramic coating so I took some more photos and posted this.

These parts are all sitting on my kitchen table so I haven't actually used any of this stuff yet but here's the idea.

We were trying to optimize each side of the air pump (engine). We wanted to keep the intake cool and the exhaust hot. We used two type of ceramic coatings. One is a dispersant coating trying to keep things cool and the other is a barrier coating trying to retain heat energy.

Here is a shot of the barrier coating applied to the stock exhaust manifold.

The next shot of the turbo shows the barrier coating on the exhaust side and the dispersant coating in the compressor side.

The entire exhaust side is coated trying to retain energy. Here is a down pipe.

The intake manifold was cleaned up, intake bells were smoothed and then dispersant coated.

And the whole reason we did all this was the heads.

Not important: are all those parts "spare" so that you actually still have a running car?
 

Those're some thorough mods you're doing! Nice!

Yeah, I've basically been collecting parts for 3 years . . .

I was gonna say "you've got a spare complete engine?!"
 

Have fun with the install! :)
