possibly a stupid question... but did that flange get cut off a head? is it just too have a perfect start for the exhaust?
Builds 80 series where to start! Again.... (12 Viewers)

It was an exhaust gasket glued together for a pattern then converted to a digital file for a CNC laser

Not a stupid question at all. It is like Dogfishlake said. The two individual intake manifold gaskets taped together and then scanned into a CNC laser machine to cut the exact shape of the gaskets in 1/2" steel.
The reason I am doing this is: I did a J-pipe with my current truck and while I think it is an outstanding solution, this turbo is much bigger so I wanted to free up some room. The path I want to take with the exhaust and the turbo outlet will work better with a one off customer turbo header, and really there is some bling factor to a badass tig welded, stainless turbo header with a CNC'd collector and stainless Tial turbine housing.
Haha and we all know I am all about the bling

You need to make it bounce off a rev limiter like the supra turbo race motors!https://youtu.be/0VoQGGz kWzo
By the way, that's not even close to fastest supra any more
Ryan fxxxing rocks.
All I have to say is that he puts the 1FZ world to shame.

Haha, not sure about rocks but this build is the put your money where your mouth is build for sure! I keep telling people not to motor swap. The 1FZ can and will run circles around your LS motors, so I guess we will really find out.
No disagreement from me. Which is why I retired my 80 series. I can't compete any more.

Lol. Certainly not a competition, but if it were a 70 series beats a motor swapped 80 any day.

Thanks for the info on the turbo header. Now it's all making sense to me. I haven't been super confident with my turbo knowledge so I'm finding this all really interesting.

Haha these are some serious chunks of metal! This is going to be a massive manifold! I do not envy Marc at all for trying to figure out how to do the equal length setup so that each runner makes it to the collector!!

Getting each cylinder to the inlet won't be bad but getting them there at equal length will be tricky

Yeah Marc only builds equal length runners on his builds. Like I said that is his problem. lol

Marc's 2JZ equal length, equal radius turbo manifold.

Yeah it is kind of WTF, but if you don't do it exactly equal length you have exhaust pulses that are hitting each other and canceling each other out instead of spooling the turbo. If it is all the exact same length, each pulse's energy goes right down the runner and into the turbine.
Makes good sense, and looks really awesome at the same time. You're going to have a very interesting sight under the hood!

That looks like a bunch of snakes f$%#ing each other under there !

Haha the old GT40 Headers used to be called Bundles of Snakes. But they could be much more attractive since they were NA and didn't have to worry about being equal length.
