Turbo exhaust manifold.

Does anybody know where I can find this? It doesn´t look custom made.

Either custom, or off a kit. Too bad there's no picture that shows the flange of the wastegate...

Where'd you get the picture from?

I think I found it here a while ago! Saved the picture, and now when it´s mani time,
I looked at diffrent designs and like this one the best! I think it is an HKS product, but
I´m not sure...
An other picture:

Doesn't look like an HKS style ss manifold to me. You have no pictures of the wastegate flange?

Yes, the last one is a custom made copy of the first one. If I remember correctly someone here made the copy of the first one, and that was what the thread was about.

Nobody knows who makes them? Where is the best place to get a good quality manifold from?

Like I said in the other thread, it's most likely a one-off custom piece.
I don't recognize the design, and it doesn't match any of the common pre-made units...at least not in the U.S.

What do you think about the design? Im going with a Tial 46mm and a
Turbonetics T66 BB Q-trim a/r 1.15 devided, would I have to worry about boostcreep? I´m most likely not planing to run more than 1.2 bar...
This is the way I´m planing to build my mani, if I don´t find someone selling them!

I don't like the placement of the wastegate pipes off the main runners, but I think the 46mm Tial should be okay.

Were would you like them to be placed? They will if I´ve understod everything correctly be more effective if they are placed more in the flow direction from the engine, but if they are placed like that wouldn´t it have a negative effect on the flow to the turbo?
Thanks for your help!

Yes, it will... but that is why the wastegate will remain closed until you have hit a specific boost pressure.
