Custom manifolds
Here are my new Intake and exhaust manifolds!
If anyone is interested I have a greddy and an HKS manifold for sale. They wouldn't fit with the turbo I am using.

Excellently fabricated!!
I'm a little perplexed as to why you went through all the trouble fabricating these manifolds without a little research done first. Perhaps you just decided to be different? I'll clarify, the exhaust manifold, why not go with the tried true proven to spool quicker AND make more power fully divided manifold? Also, bends within 3" of the turbine entrance can hurt some of the dynamics within the turbine also. And for the beautiful intake, there’s been a lot of research showing that having the inlet to each runner being flush with one wall or more within the plenum makes better torque and horse power overall then the velocity stacks being placed inside the plenums. Your still supposed to use a velocity stack type entrance to the runner, just not have it protrude into the plenum. Not trying to burst your bubble, its very VERY well fabricated pieces and will yet show good numbers and should perform extrremely well I'm sure. Its just not 100% as optimal as one could get while going through the work of making custom parts.
Again, nice work and it should have some impressive numbers.

If I could have put that large of a turbo elswhere the design of the manifold would have been different but you do what you can with the space you got. But thanks for the compliments. We'll see in the end what the numbers really are.

Here is a dyno map of a car with the same style header on a different car, smaller turbo. Seems to work just fine to me.

That's awesome work. Love seeing new and custom stuff. Personally I am most thrilled about the o-rings used in the lower intake. Why has no one thought of this before?
I share the concerns regarding the length of the turbo runners, as well as the decision to merge them before the turbine housing. It's been fairly clearly demonstrated that keeping them divided will result in a massive increase in response.
If you were worried about fitting a large turbo, it's really not that much of a concern:
It's much higher then yours though.
Another area of concern might be the brace that is run between the turbo and engine. With so much stainless supporting the turbo, I'd worry about movement. You might find that the brace is causing cracks in the manifold and not preventing them. One reason I have elected to not run such a brace.

It appears that the turbo is "hanging" from the brace with a balljoint connection, allowing for thermal expansion movement while still providing support. I'm making a brace right now with two balljoints between the engine and brace, but I think the hanging turbo method would prolly work even better.

I don't see an issue with that exhaust manifold at all. In fact it's very very nice. The bend before the turbo isn't that bad. The turbo itself is a pretty good restriction and messes up flow anyways. Luckily it gives back FAR more than it takes! That's actually one of the few really nicely designed manifolds I've seen here. Good job. Take a look at a Champ Car exhaust manifold setup sometime. It looks an awful lot like that in design. There is even a bend right before the turbo but of course you also have to work within a small space in those cars. When it comes to turbos, you can actually mess up pretty badly and still get good results. You aren't going to see any issues with this setup.

let me offer my praises on the aesthetics of your setup. i'm at a bit of a loss on the technical advanatges (or drawbacks) of it. i can understand the protrusion of the velocity stacks not being necessary in the plenum, but the exhaust is where things start to get a bit over my head. i don't know enough to have a real opinion.
i used to know Eric (Grim) from when he was with Performance Factory back home in NY. i'm glad to see him and his brother doing such BIG things! as long as he hasn't changed since then, he knows his **** and i can say you're getting what he truly feels is the best - not just flash.
i expect to see great results when your car is done. one question though: what are you doing about your water pump. it seems that the turbo brace/anchor (weight relief) is attached to where one of the water pump mounts is.

If you look closely of the third pic above , you'll see a Miziere (?) EWP .

And yes it is a mezerie electric water pump.
Thanks diabolical1. Yeah grim and his brother are good friends of mine. They have put a lot into this car and I hope to get it done soon.
Thanks Rotarygod.

Nice ducting! It's also nice to finally see someone with a turbo get the air filter out of the damn heater of an engine bay. I don't know why more people don't do this? Contrary to popular belief the turbo is not making up for the less dense hot air so I'm clueless as to the logic. This may be the nicest setup I've seen on this forum yet. If it isn't, I can't remember what was done better. Bring it to Sevenstock in September. I'd love to see it in person.

Not too sure about that car but I am gonna try to finish my car by seven stock. And DRIVE it there. But unfortunately there is yet a lot of body work that needs to be done also. But I will definatly try to get Jack to bring his car.
