Best turbo for 617 in an SD - Page 3 - PeachParts Mercedes-Benz Forum

I would think the three head flanges and turbo flange would need to be pre-cut.

Make it with a GT2056 flange

Here is a stock T3 flange:

Anyone else interested in a set, I know it will depend upon price and quality. If I make more than my own set, I will have to run the bending thru the shop. I will sell them at cost, which should be fairly low, depending on how many bends it will take.

Diesel kid can make the head/turbo flanges---if he doesnt already have a program scanned, I think he does stainless too. theres a thread---"need something fabricated" by dieselkid

Are you willing to post the technical specs for the parts produced? I wouldn't mind helping to throw a cad model together. An open-source performance manifold would be pretty darn cool.

Edit: I don't want to steal business from dieselkid (he's probably got a faster turnaround than me) but I can occasionaly make/get custom parts in a pinch if needed. (read:my free time=none)

I am not trying to make any money from this project, so yes I will provide any specs I can. Any input from any of you guys is appreciated.

Bgkast, Not sure on what turbo I will use. Probably a GT2256.

If I can get the dimensions of the 2056, I could make one up just as easy.

Here's bgkast's post about the GT2056V adapter to the stock manifold. This might help. Bryan probably has a better schematic or can elaborate more on this pic.

Purple - Threaded 8mm (will have studs inserted to mount GT2056V)

Cool, that will help.

Equal length header is going to be hard to do within the space limitations. Unequal length would be pretty easy and I don't think you would ever notice a difference in power.

I will see what I can do. I don't have mine apart yet. What is the exhaust port size? I will start checking out what dies we have once I know what the port size is so I can figure on a tubing size.

I think If I do all of this, I will run off 4 or 5 sets.

Did this header project ever get off the ground?

Also interested in any other turbo options. Thanks.
