Start of the duratec manifold. I'm hoping this manifold will not only replace the cheap cast manifolds available from china but also fit an efr turbo

Looks great; couple of questions. Is that a t3 flange? I know you can get efr turbos with a internal wastegate but are including or making an external wastegate an option?

I'm still undecided on what all options I want to offer. This manifold will be a t25 since I'm mainly concerned with using a efr 6258 or 6758. But I may have a t3 ewg option in case there is any interest. It just makes jigs much more complicated

Looks great. Wish you were doing this 7 years ago when I made my manifold. [cheers]
At the time there were no aftermarket Duratec manifolds, and FSWerks refused to sell me their manifold.

Yeah I would have liked to have been a part of all your builds. But 7 years ago I wasn't good enough to build them like this lol

I'm hoping to get my hands on an st to build a kit for them while they are still fresh. I have a friend that just bought one but he lives 300 miles away now

Looks good. Like sporadic said, wish this was available when I was doing my build. I still might be interested in the t3 one though. Hopefully swapping in the hy35 here soon.

On a friends rear mount setup we did, he used the tial mvs wastegate. Was thinking of doing that because of the vband style. Less chance for leaks.

Nothing yet. Everything got pushed back. Just mock ups for now. I have everything but pistons and gaskets for the engine build. And still need a clutch. The plan was to cut the dump tube I have it run straight down but not sure if I want to recirculate it to the dp.

I would dump it if at all possible. Esp if you are planning to run 15 plus. It will help get more air out which is always good but I could understand someone running only 10psi would want it recir bc it would be opening all the time lol

I'm planning big boost. That's why I picked that turbo they spool like a beast. Dsm guys on this are getting great numbers on high boost with really quick spool. I will run at least 15 on street but plan on doing 20+
